1. Solution

• Background

  • RequireFeatures on a permission definition hides that permission when the required feature is disabled for the current tenant. Host has no tenant context; if the feature you reference is not enabled for the Host side, all children (menu items bound to those permissions) disappear for Host admins.
  • StateCheckers allow custom enable/disable logic per permission (e.g., “bypass for host, check feature for tenants”), but they only affect the permission state. If your Angular menus are not also filtered by permission/feature, a menu item can still render and then fail with 403 when navigated.
  • In microservice + Angular, menu visibility depends on:
    • The permission attached to the menu item (requiredPolicy in Angular).
    • Feature checks (optional) you apply in the menu contributor.
    • The actual grant rows in PermissionGrants for the current user/role/tenant.

• Part A: Host admin can still see “Management Service” when RequireFeatures is used

  1. Ensure features are enabled for Host if you want Host to see these permissions.
     • In the Feature Management UI, switch to Host side and enable the features required by your permissions (e.g., CarbonFeatures.Categories, CarbonFeatures.CategoryTypes, etc.). If you manage features programmatically, set default values for the host:

public class CarbonFeatureDefinitionProvider : FeatureDefinitionProvider
     {
         public override void Define(IFeatureDefinitionContext context)
         {
             var group = context.AddGroup("CarbonFeatures");
             group.AddFeature("CarbonFeatures.Categories", defaultValue: "true"); // host-default
             group.AddFeature("CarbonFeatures.Categories.Create", defaultValue: "true");
             group.AddFeature("CarbonFeatures.Categories.Edit", defaultValue: "true");
             group.AddFeature("CarbonFeatures.Categories.Delete", defaultValue: "true");

             group.AddFeature("CarbonFeatures.CategoryTypes", defaultValue: "true");
             group.AddFeature("CarbonFeatures.CategoryTypes.Create", defaultValue: "true");
             group.AddFeature("CarbonFeatures.CategoryTypes.Edit", defaultValue: "true");
             group.AddFeature("CarbonFeatures.CategoryTypes.Delete", defaultValue: "true");
         }
     }

2. Alternatively, keep RequireFeatures for tenants, but bypass feature checks for host via StateCheckers:

public sealed class HostBypassFeatureChecker : ISimpleStateChecker<PermissionDefinition>
     {
         public async Task<bool> IsEnabledAsync(SimpleStateCheckerContext<PermissionDefinition> context)
         {
             var currentTenant = context.ServiceProvider.GetRequiredService<ICurrentTenant>();
             if (!currentTenant.IsAvailable) // Host
                 return true;

             var featureChecker = context.ServiceProvider.GetRequiredService<IFeatureChecker>();
             // Map permission name to feature name as you need
             var featureName = MapPermissionToFeature(context.State.Name);
             return await featureChecker.IsEnabledAsync(featureName);
         }

         private static string MapPermissionToFeature(string permissionName)
         {
             // Example mapping: adjust to your permission constants
             if (permissionName.StartsWith(ManagementServicePermissions.Categories.Default))
                 return "CarbonFeatures.Categories";
             if (permissionName.StartsWith(ManagementServicePermissions.CategoryTypes.Default))
                 return "CarbonFeatures.CategoryTypes";
             return permissionName; // fallback
         }
     }
     // Apply to your permission definitions:
     var category = myGroup.AddPermission(ManagementServicePermissions.Categories.Default, L("Permission:Categories"));
     category.StateCheckers.Add(new HostBypassFeatureChecker());

 This approach keeps the Host menu visible without requiring Host features to be explicitly enabled.

• Part B: Prevent tenants from seeing menu pages that are not included in their package
  • Root cause in your scenario: the Angular menu item appears because the permission used by the menu item is granted (or no permission was bound to the menu item). Clicking leads to 403 because the page or API requires a different permission that is not granted.
  • Fixes:
    1. Ensure each Angular route/menu item uses a permission that exactly matches your backend permission for that page. Do not use a “broader” parent permission if you want to hide the page when a sub-feature is disabled.
       • Angular route guard:

{
           path: 'category-types',
           component: CategoryTypesComponent,
           canActivate: [PermissionGuard],
           data: { requiredPolicy: 'ManagementService.CategoryTypes' }
         }

   - Menu item:

this.context.addItem({
           id: 'ManagementService.CategoryTypes',
           text: 'Category Types',
           icon: 'fa fa-list',
           order: 10,
           requiredPolicy: 'ManagementService.CategoryTypes'
         }, MANAGEMENT_MENU_NAME);

   - If you need feature-level hiding too, add a feature check in the menu contributor and skip adding the item when feature is disabled for the current tenant.
2) Do not grant the permission in the tenant’s package if the page must be hidden. If you are generating grants dynamically, verify PermissionGrant table has no rows for the excluded pages. Your observation is correct: once the grants are removed, the menu is hidden provided you use requiredPolicy on the menu item.
3) If you keep using StateCheckers (bypass for host, check feature for tenant), keep menu items bound to those exact permissions. Since ABP UI reads permission states, menu entries disappear for tenants when the feature is disabled.
4) For microservice solutions with dynamic permissions: verify the PermissionDefinition names you bind in Angular match the definitions pushed by that microservice. A mismatch leads to menu items always visible due to missing policy binding.

• Part C: Known edge cases and recommendations

  • Use RequireFeatures on permission definitions only if you also want menus and API access to follow the same feature switches. If host must always see, either enable those features for Host or switch to StateCheckers that bypass for host.
  • In Angular, always set both:
    • canActivate PermissionGuard on routes.
    • requiredPolicy on menu items. This guarantees no “visible but 403 on click” inconsistency.
  • If you need a package concept: treat the package assignment flow as feature/permission provisioning. When a package is assigned to a tenant, grant only the permissions of included pages. When a package excludes a page, ensure those permissions are not granted. Use your provisioning service to synchronize PermissionGrant records accordingly.

• Minimal example putting all together

  • Permission definitions:

public class ManagementServicePermissionDefinitionProvider : PermissionDefinitionProvider
  {
      public override void Define(IPermissionDefinitionContext context)
      {
          var group = context.AddGroup("ManagementService");

          var categories = group.AddPermission("ManagementService.Categories", L("Permission:Categories"));
          categories.StateCheckers.Add(new HostBypassFeatureChecker()); // host bypass
          categories.RequireFeatures("CarbonFeatures.Categories");      // tenant feature

          var categoryTypes = group.AddPermission("ManagementService.CategoryTypes", L("Permission:CategoryTypes"));
          categoryTypes.StateCheckers.Add(new HostBypassFeatureChecker());
          categoryTypes.RequireFeatures("CarbonFeatures.CategoryTypes");
      }
  }

• Angular route and menu:

// route
  { path: 'categories', component: CategoriesComponent, canActivate: [PermissionGuard], data: { requiredPolicy: 'ManagementService.Categories' } }
  { path: 'category-types', component: CategoryTypesComponent, canActivate: [PermissionGuard], data: { requiredPolicy: 'ManagementService.CategoryTypes' } }

  // menu
  this.context.addItem({
    id: 'ManagementService',
    text: 'ManagementService',
    icon: 'fa fa-book',
    order: 30
  });

  this.context.addItem({
    id: 'ManagementService.Categories',
    text: 'Categories',
    parentId: 'ManagementService',
    requiredPolicy: 'ManagementService.Categories'
  });

  this.context.addItem({
    id: 'ManagementService.CategoryTypes',
    text: 'Category Types',
    parentId: 'ManagementService',
    requiredPolicy: 'ManagementService.CategoryTypes'
  });

• Feature defaults for host (optional) if you prefer RequireFeatures without StateChecker bypass:

public class CarbonFeatureDefinitionProvider : FeatureDefinitionProvider
  {
      public override void Define(IFeatureDefinitionContext context)
      {
          var g = context.AddGroup("CarbonFeatures");
          g.AddFeature("CarbonFeatures.Categories", defaultValue: "true");
          g.AddFeature("CarbonFeatures.CategoryTypes", defaultValue: "true");
      }
  }

This approach will:

• Make Host admin always see and access Management Service (via host-bypass or enabling host features).
• Make tenants see only the pages included in the package because only those permissions will be granted and the menu items require those permissions; excluded pages won’t appear at all, avoiding the 403-on-click experience.

1. Solution

• Cause: CMS Kit Blog pages ship their own Bootstrap container/row markup and some generic CSS. In LeptonX for Blazor, the application body already uses a flex/grid layout and spacing utilities. When the blog list and post components render inside the layout, duplicated container/row wrappers and a few global CSS classes from the Blog module can break the page width and push the sidebar/header out of alignment.

• Fix 1 — Update LeptonX and CMS Kit to the latest compatible versions for ABP 9.3.x:

  • Ensure all UI packages are aligned to your ABP version (9.3.6). Mismatched minor versions easily cause layout glitches.
  • In all Blazor UI projects, align these packages:
    • Volo.Abp.AspNetCore.Components.Web.LeptonXTheme
    • Volo.CmsKit.Pro.Public.Web and Volo.CmsKit.Pro.Admin.Web (or the non-Pro equivalents if you use the open-source CMS Kit)
  • After updating, clean and rebuild.

• Fix 2 — Remove conflicting container wrappers in your CMS Kit page overrides:

  • If you customized/overrode any Blog razor components (List or Detail) under your project (e.g., Pages/CmsKit/Blogs/* or Components/Blogs/*), remove extra Bootstrap container/row/col wrappers. LeptonX already handles the main container. Keep only the content block.
  • Example (pseudo-diff):

<!-- Before -->
    <div class="container">
      <div class="row">
        <div class="col-12">
          @* Blog content *@
        </div>
      </div>
    </div>

    <!-- After -->
    @* Use LeptonX content area; no extra container *@
    @* Blog content *@

• Fix 3 — Ensure you’re not importing Blog CSS globally:

  • If you added custom blog CSS to wwwroot/styles.css or imported a third-party blog stylesheet globally, scope it to the blog components only, or remove global selectors that target html/body/.container/.row. Use a wrapper class (e.g., .blog-page) in the blog components and prefix selectors accordingly.

• Fix 4 — Verify LeptonX app layout and content container:

  • Make sure your MainLayout is using the default LeptonX layout and that your content is placed inside the provided content area. Avoid adding additional wrappers with fixed widths.
  • If you replaced any LeptonX layout component (Header, Footer, ContentContainer), revert to the default or re-implement with the same structure to preserve the layout.

• Fix 5 — Clear cached assets:

  • Delete bin/obj, purge wwwroot (generated bundles), and restart the app. If you use static versioning, increment the bundle version so browsers fetch the new CSS.

1. Solution

• Reason: The client (Login/Register/ChangePassword pages) adds its own validators. If you lower Identity password requirements on the server (e.g., RequiredLength = 3), but the UI still shows “min 6” (or other rules), it means the client-side validators are not refreshed or they are hard-coded/defaulted.

• Fix (Angular UI):

  1. Make sure the password rules are coming from the dynamic application configuration and not hard-coded. Update ABP Angular packages to the latest compatible version.
     • Run:
       • yarn upgrade @abp/ng.core @abp/ng.account.core @abp/ng.account @volo/abp.ng.identity.config
       • Delete node_modules and yarn.lock (or package-lock.json) and reinstall.
  2. Ensure the Register/ChangePassword forms use the validators provided by @volo/abp.ng.identity.config (or read them from getApplicationConfiguration) instead of a fixed Validators.minLength(6). Any local form code that sets Validators.minLength(6) must be changed to use the value from configuration (identity.password.requiredLength).
  3. After changing settings at runtime, refresh application configuration so the UI gets new rules. A full page reload always works. In SPA scenarios where you change settings without reload, reinitialize CurrentApplicationConfiguration on the client after saving settings.

• Fix (MVC UI):

  • Remove any hard-coded minlength attributes or model validators that conflict with IdentityOptions and bind to the IOptions<IdentityOptions>.Value.Password.RequiredLength for client validation metadata, or disable conflicting client rules.

• Notes:

  • Server-side validation always uses the backend settings (IdentityOptions). Even if the client lets a weak password through, the server will still reject it if it violates current rules.
  • Historically, mismatches were fixed by updating the identity config package in Angular projects. If you’re on an older version, upgrade the UI packages to align with backend rules.

1. Solution

• You can’t load Lepton (v1) and LeptonX themes at the same time. Both modules register the same keys and services (e.g., AbpErrorPageOptions.ErrorViewUrls["401"], DefaultTheme, toolbar contributors, bundle names), which causes “An item with the same key has already been added” and “service not registered” errors. ABP supports only one active MVC theme per application.

• Pick one theme and remove the other theme module(s) and registrations:

  • If you want LeptonX:
    • Remove AbpAspNetCoreMvcUiLeptonThemeModule from all DependsOn attributes and delete any custom module inheriting from AbpAspNetCoreMvcUiLeptonThemeModule.
    • Add AbpAspNetCoreMvcUiLeptonXThemeModule to your Web module DependsOn.
    • Remove any Configure<AbpErrorPageOptions>() entries you copied from Lepton to avoid duplicate keys; LeptonX already configures these.
    • Ensure you register the theme in AbpThemingOptions only once (DefaultThemeName should be LeptonXTheme.Name or let LeptonX register itself).
    • If you use LeptonX theme management/settings, add Volo.Abp.LeptonXTheme.Management.Domain.Shared to your Domain.Shared project and add [DependsOn(typeof(LeptonXThemeManagementDomainSharedModule))] to your domain shared module.
  • If you want Lepton (v1):
    • Remove AbpAspNetCoreMvcUiLeptonXThemeModule from DependsOn and any LeptonX nuget/package references.
    • Keep AbpAspNetCoreMvcUiLeptonThemeModule and its options.

• Do not inherit one theme module from the other. Theme modules are independent and each configures its own services/options. Inheriting or registering both leads to duplicate option keys and missing service registrations for the “current theme” resolver.

• After changes:

  • Clean and rebuild to ensure only one theme remains:
    • abp clean
    • dotnet restore
    • dotnet build
  • If you switched to LeptonX and see “Undefined setting: Volo.Abp.LeptonXTheme.ApplicationLayout”, add the LeptonX theme management shared module as noted above.

Code example (use LeptonX only):

using Volo.Abp.AspNetCore.Mvc.UI.Theming;
using Volo.Abp.Modularity;
using Volo.Abp.AspNetCore.Mvc.UI.Theme.LeptonX;

[DependsOn(
    typeof(AbpAspNetCoreMvcUiLeptonXThemeModule)
    // remove: typeof(AbpAspNetCoreMvcUiLeptonThemeModule)
)]
public class MyWebModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        Configure<AbpThemingOptions>(options =>
        {
            // Don’t add Lepton and LeptonX together
            options.Themes.Add<LeptonXTheme>();
            options.DefaultThemeName = LeptonXTheme.Name;
        });

        // Remove duplicate error page mapping if you had both:
        // Configure<AbpErrorPageOptions>(options => { ... }); // Not needed for LeptonX
    }
}

If you need to switch themes dynamically at runtime, implement a single theme that changes its resources/layouts based on a setting or cookie rather than loading two different theme modules simultaneously.

1. Solution

• Why this happens

  • In LeptonX/LeptonX Lite for Blazor, the login page header uses the Branding component. Its rendering logic is:
    • If LogoUrl is set (not null/empty), it shows only the logo (no AppName text).
    • If LogoUrl is null/empty, it shows the AppName text (and uses a default logo elsewhere if needed).
    • Therefore, when you override LogoUrl, AppName is intentionally hidden.
  • The logo size on the login page is controlled by the theme’s CSS for the Branding component. If your custom asset has extra whitespace or different intrinsic dimensions/aspect ratio, it can appear smaller.

• Keep AppName visible and customize the logo Option A: Use LogoUrl only inside the app shell, not on the login page

  • Override the login page Branding with your own component so you can render both logo and AppName:
    1. Create a custom Branding component override under your Web project to replace the theme’s Branding on the login page:
    • Create file: /Themes/LeptonX/Components/Branding/Default.razor (path must match the theme component to override).
    • Example implementation:

@inject Volo.Abp.Ui.Branding.IBrandingProvider Branding

      <div class="lpx-branding lpx-branding--login">
          <img src="@Branding.LogoUrl" alt="@Branding.AppName" class="lpx-branding__logo" />
          <div class="lpx-branding__title">@Branding.AppName</div>
      </div>

      @code { }

- Add minimal CSS to keep original sizing:
  - Add to wwwroot/global-styles.css (or your bundle):

.lpx-branding--login {
          display: flex;
          flex-direction: column;
          align-items: center;
          gap: .5rem;
        }
        .lpx-branding__logo {
          height: 56px; /* similar to default */
          width: auto;
        }
        .lpx-branding__title {
          font-size: 1.5rem;
          font-weight: 600;
        }

- This ensures both the logo and AppName are shown on login regardless of LogoUrl.

Option B: Do not override LogoUrl; use LeptonX CSS variables

• LeptonX supports logo customization via CSS variables. If you only set:

:root .lpx-theme-light {
      --lpx-logo: url('/images/logo/leptonx/icon-logo.svg');
      --lpx-logo-icon: url('/images/logo/leptonx/icon.svg');
    }
    :root .lpx-theme-dark,
    :root .lpx-theme-dim {
      --lpx-logo: url('/images/logo/leptonx/icon-logo.svg');
      --lpx-logo-icon: url('/images/logo/leptonx/icon.svg');
    }

- Keep DefaultBrandingProvider.LogoUrl = null (do not override), and keep AppName override as desired:

[Dependency(ReplaceServices = true)]
      public class AbpTabsBrandingProvider : DefaultBrandingProvider
      {
          public override string AppName => "AbpTest";
          // Do not override LogoUrl -> keep base.LogoUrl (null) so AppName is displayed
      }

- The theme will use your CSS-defined logos in the layout while still showing AppName on the login page.

• Keep the logo size consistent
  • Ensure your SVG has a proper viewBox and no excessive whitespace.
  • Control size with CSS in your override or by targeting the default selector:

/* If not overriding component, target default branding image on login */
    .lpx-auth .lpx-branding img, 
    .lpx-auth .lpx-branding svg {
      height: 56px;
      width: auto;
    }

• If your asset is small intrinsically, set a consistent height in CSS as above.

• Per-tenant branding

  • If you need tenant-specific logos:
    • Keep the override in BrandingProvider, but move tenant logic into CSS variables or component override rather than setting LogoUrl. You can:
      • Use settings per tenant to change CSS variables via a Layout Hook or a small style tag injected at runtime.
      • Or override the Branding component and compute the URL per tenant, while still rendering AppName alongside the image (as in Option A).

• Summary of what to change

  1. Remove your override of LogoUrl (to show AppName again), and switch to LeptonX CSS variables for logos; or
  2. Keep LogoUrl override and override the Branding component for the login page to render both the image and AppName; and
  3. Add CSS to enforce a consistent logo height (e.g., 56px) on the login page.

1. Solution

• Root cause: In ABP v9.2+ Angular UI packages were migrated to standalone. If your app still uses NgModule-based components, ABP Angular elements like abp-button (emitting abpClick) and abp-modal (content projection, submit wiring) will only work if their standalone imports/providers are added to your module (or component) explicitly. Using (click) works because it’s plain Angular, but abpClick is an ABP output from the ButtonComponent and requires importing the ABP button component/directives into the module where it’s used.

• Fix: Import the ABP Angular standalone components into your module via the provided module-level re-export (for non-standalone apps), or import the components directly in a standalone component’s imports.

For a non-standalone component declared in an NgModule:

// app.module.ts (or a feature module where your modal component is declared)
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
// Bring ABP Angular shared directives/components into module-based apps:
import { AbpThemeSharedModule } from '@abp/ng.theme.shared'; // re-exported compatibility module

import { MyFeatureComponent } from './my-feature.component';

@NgModule({
  declarations: [MyFeatureComponent],
  imports: [
    CommonModule,
    AbpThemeSharedModule, // IMPORTANT: provides abp-button, abp-modal, directives like abpClose, abpPermission, etc.
  ],
})
export class MyFeatureModule {}

If you don’t have AbpThemeSharedModule (depending on version), import the specific components into your module via their modules (compatibility packages) or switch your component to standalone and import the components there:

// my-feature.component.ts (standalone variant)
import { Component } from '@angular/core';
import { ButtonComponent } from '@abp/ng.theme.shared/components/button';
import { ModalComponent } from '@abp/ng.theme.shared/components/modal';

@Component({
  selector: 'app-my-feature',
  standalone: true,
  imports: [ButtonComponent, ModalComponent],
  template: `
    <abp-modal [(visible)]="isOpen">
      <ng-template #abpHeader>Title</ng-template>
      <ng-template #abpBody>Body</ng-template>
      <ng-template #abpFooter>
        <abp-button (abpClick)="onSubmit()">Submit</abp-button>
      </ng-template>
    </abp-modal>
  `,
})
export class MyFeatureComponent {
  isOpen = true;
  onSubmit() { /* ... */ }
}

• Ensure you’re using the ABP button output:

<!-- inside modal footer/body -->
<abp-button (abpClick)="onSubmit()" [buttonType]="'button'">
  Save
</abp-button>

• Double-check that there isn’t an overlay or disabled state blocking clicks:

  • abp-modal’s [busy] input sets the projected abpSubmit button’s loading state and prevents closing; if you set [busy]="true" permanently, clicks may appear ignored. Make sure [busy] is false when you expect interaction.
  • If your footer uses a native button with [disabled], that will bypass abpClick because it won’t fire.

• If you are wiring form submit:

  • Either use form="form-id" with a native button and handle (ngSubmit) on the form, or use abp-button with (abpClick). Mixing disabled states can give the impression of “no click”.

• Summary checklist for module-based app:

  1. Import AbpThemeSharedModule (or the required ABP Angular compatibility modules) in the NgModule that declares the component using abp-modal/abp-button.
  2. Use (abpClick) on abp-button.
  3. Verify [busy] and disabled states aren’t blocking the event.

1. Solution

• ABP 9.x targets .NET 9. The official migration guide states that if you plan to use ABP 9.0, you need to migrate your solutions to .NET 9.0. Therefore, ABP 9.0/9.1 packages (for example, Volo.Saas.Host.Application 9.0.0) are not compatible with net8.0 and will produce NU1202 (exactly like in your screenshot), because those packages include net9.0 TFMs.

• What you can do:

  • Option A (stay on .NET 8): Keep your solution on ABP 8.x (latest 8.3.4) which fully supports .NET 8.
  • Option B (move to ABP 9.x): Upgrade your solution to .NET 9 (update TargetFramework to net9.0 and update Microsoft.* packages to 9.0.0) and then update ABP to 9.x.

• Minimal steps for Option B (upgrade to .NET 9 + ABP 9.x):

  1. Install .NET 9 SDK.
  2. Change all project <TargetFramework> to net9.0 (and update global.json if present).
  3. Upgrade Microsoft.* NuGet packages to 9.0.0.
  4. abp update (to move ABP packages to 9.x).
  5. Apply the ABP 9 migration adjustments (e.g., MapAbpStaticAssets if applicable), as per the guide.

  • The package Volo.Saas.Host.Application 9.0.0 only provides net9.0; your project targets net8.0. NuGet raises NU1202: “not compatible with net8.0”.

1. Solution

• Current behavior (ABP v9.1.1, Angular): Idle Session Timeout works per-tab. The built-in Account Idle Session Timeout feature does not synchronize timers across multiple open tabs/windows by default. Each tab runs its own activity watcher and countdown. This is why you observe inconsistent behavior across tabs.

• Implement multi‑tab sync (Angular) using storage events:

  • Goal: when user activity happens in any tab, reset the idle timer in all tabs; when warning/timeout occurs in one tab, all tabs show the same warning/perform logout.
  • Approach: broadcast activity and timer-state via localStorage and subscribe to the storage event in every tab.

  Example implementation outline:

  1. Create a small cross-tab channel

// src/app/core/idle-sync.service.ts
  import { Injectable, NgZone } from '@angular/core';

  const CHANNEL_KEY = 'abp-idle-sync';
  type IdleSyncMessage =
    | { t: 'activity'; ts: number }
    | { t: 'show-warning'; deadline: number }
    | { t: 'cancel-warning' }
    | { t: 'timeout' };

  @Injectable({ providedIn: 'root' })
  export class IdleSyncService {
    constructor(private zone: NgZone) {
      window.addEventListener('storage', (e) => {
        if (e.key !== CHANNEL_KEY || !e.newValue) return;
        const msg = JSON.parse(e.newValue) as IdleSyncMessage;
        this.zone.run(() => this.onMessage?.(msg));
      });
    }

    onMessage?: (msg: IdleSyncMessage) => void;

    notify(msg: IdleSyncMessage) {
      // write-then-remove to trigger storage event in other tabs
      localStorage.setItem(CHANNEL_KEY, JSON.stringify(msg));
      localStorage.removeItem(CHANNEL_KEY);
    }
  }

2. Wire it to ABP’s idle feature hooks (Angular):

• In your app’s root component (or a dedicated initializer), listen to user activity and dispatch “activity” messages.
• Hook into the idle warning display/hide and timeout actions to broadcast “show-warning”, “cancel-warning”, and “timeout”. Also react to incoming messages by invoking the same UI actions locally (so all tabs stay in sync).

Example:

// src/app/app.component.ts
  import { Component, HostListener, OnInit } from '@angular/core';
  import { IdleSyncService } from './core/idle-sync.service';
  import { AccountIdleSessionTimeoutService } from '@abp/ng.account/config'; // service used internally by ABP Account Angular UI

  @Component({ selector: 'app-root', template: '<router-outlet></router-outlet>' })
  export class AppComponent implements OnInit {
    constructor(
      private idleSync: IdleSyncService,
      private idleService: AccountIdleSessionTimeoutService
    ) {}

    ngOnInit() {
      // 1) When local idle feature is about to show warning, broadcast to others
      this.idleService.onShowWarning$.subscribe((deadlineUtcMs) => {
        this.idleSync.notify({ t: 'show-warning', deadline: deadlineUtcMs });
      });

      // 2) When local warning is cancelled (user activity), broadcast
      this.idleService.onCancelWarning$.subscribe(() => {
        this.idleSync.notify({ t: 'cancel-warning' });
      });

      // 3) When local timeout happens (logout), broadcast
      this.idleService.onTimeout$.subscribe(() => {
        this.idleSync.notify({ t: 'timeout' });
      });

      // 4) React to messages from other tabs
      this.idleSync.onMessage = (msg) => {
        switch (msg.t) {
          case 'activity':
            this.idleService.resetTimerFromExternalActivity(); // custom helper; see below
            break;
          case 'show-warning':
            this.idleService.showWarningExternally(msg.deadline);
            break;
          case 'cancel-warning':
            this.idleService.cancelWarningExternally();
            break;
          case 'timeout':
            this.idleService.triggerTimeoutExternally();
            break;
        }
      };
    }

    // Broadcast user activity from this tab
    @HostListener('document:mousemove')
    @HostListener('document:keydown')
    @HostListener('document:click')
    onActivity() {
      this.idleSync.notify({ t: 'activity', ts: Date.now() });
    }
  }

3. Expose minimal helpers on top of ABP’s idle Angular service:

• If the ABP Angular Account idle service you use doesn’t expose such methods, wrap/extend it where you already subscribe to its events (warning start/cancel, timeout). The idea is to:

  • Keep one source of truth for the timer per tab (the existing ABP idle service),
  • On incoming “activity” message, simply call the same “reset” logic you use when the user moves mouse/presses key,
  • On “show-warning/cancel/timeout” messages, call the same internal methods you call locally to show/cancel the warning modal or sign out. If needed, implement a thin facade service that calls to the ABP components or dispatches the same RxJS streams they use.

• Notes:

  • Use localStorage, not sessionStorage. The browser fires “storage” events only across tabs for localStorage.
  • Include a debounce/throttle if you want to reduce the activity message rate.
  • If you cannot call internal methods of the ABP idle service, mirror the behavior by:
    • Stopping/starting your local countdown timer when “activity” arrives,
    • Opening/closing the same warning modal component with the same translations and deadline,
    • Calling the existing sign-out flow on “timeout” (e.g., AuthService.logout()).

1. Solution

• ABP’s Idle Session Timeout feature already works across multiple tabs of the same browser profile. It uses browser storage and a single activity monitor to keep all tabs in sync: user activity in any tab resets the idle timer, and when the warning/timeout is reached, all tabs react consistently.

• To enable and configure it in Angular (v9.1.1):

  1. Ensure the Account Module is added on the backend and the Idle Session Timeout setting is enabled.
  2. Configure settings (host or tenant) in Settings > Account > Idle Session Timeout:
     • Enable Idle Session Timeout
     • Idle Time (minutes)
     • Show Warning Before (seconds)
  3. No extra Angular code is needed for multi-tab handling. The module’s built-in logic listens to user activity events (mouse, keyboard, click, etc.) and coordinates via storage so that all tabs share the same idle state.

• If you want to customize behavior:

  • You can change thresholds or disable the feature per tenant/host from settings.
  • If you need to completely disable the feature for all users, set it off in Settings or override/hide the related setting UI (Angular) as a customization.
