Hello... I have an issue in the Blazor server

if I want to change the layout for this page to a custom layout.... I use @layout in any razor component it works fine without any problem, but if I have @attribute [Authorize("PolicyName")]; I get an error if I refresh the browser only. if I put Authorize for Roles it works fine without any error (when I refresh the browser) @attribute [Authorize(Roles="Roles")]; or @attribute [Authorize];

    Hi @liangshiwei I create the Blazor server Project with public web site then i Create the table in Db using Abp Suite then i create layout from the sorce code of leptonX theme i put the layout in the page i created is the new one

    when i run the project app start on the home page then when i navigate to my created page it is worked when i refresh the browser (already i am in the created page ) and put authorize property with policy name i got this error

    this is layout page

    this is my crud page

    if you remove the @attribute [Authorize(BlazorTutorialPermissions.TabledPageInformations.Default)]; with this @attribute [Authorize]; or @attribute [Authorize(Roles="R1,R2")];

    I sent the code to your email.

    if you change the code in test page to @attribute [Authorize("Any Policy You Have")]; in stead of @attribute [Authorize]; it will happen

    Hi,

    It's a bug,we will fix it in the next version.

    You can download the Lepton X Pro module and replace packages reference with local reference.

    Find MainHeader and MainMenu components and update the Dispose method:

    public void Dispose()
    {
        if (Menu != null)
        {
            Menu.StateChanged -= RefreshMenu;
        }
    }
    
    public void Dispose()
    {
        if (Menu != null)
        {
            Menu.StateChanged -= Menu_StateChanged;
        }
    
        AuthenticationStateProvider.AuthenticationStateChanged -= AuthenticationStateProviderAuthenticationStateChanged;
    }
