cellero created
- ABP Framework version: v4.4.0
- UI type: Blazor Server
- DB provider: EF Core
- Tiered (MVC) or Identity Server Separated (Angular): no
The create modal crashes when a required field is left empty. The bug is easy to replicate
- Use Abp Suite to create a simple entity with a required field/property
- Run the Blazor app and click on the "+ New xx" button
- Press save without completing any fields
- The error will occur.
Note that on update, the UI does provide feedback, but still crashes when pressing the save button.
Please advise the correct approach for solving this issue and can confirm it is a bug to be solved.
Thanks.

Hi @cellero, please wrap your create and update methods with try-catch blocks and handle exception by yourself (by using
HandleErrorAsyncmethod). => https://support.abp.io/QA/Questions/1523/Blazor-Server-ABP-Exception-Dialog-not-shown#answer-7939465b-3349-3100-2cc1-39fd4fd8c78aprivate async Task CreateBookAsync() { try { await BooksAppService.CreateAsync(NewBook); await GetBooksAsync(); CreateBookModal.Hide(); } catch (Exception ex) { await HandleErrorAsync(ex); } }- Please also be sure about your *.razor page inherits from your base component.
@page "/books" @attribute [Authorize(MyPermissions.Books.Default)] @inherits MyPageComponentBase //be sure about your razor page inherits from your base component ///... -

Thank you for your prompt reply. I have implemented this work around. Hopefully this is being worked on to be handled by the ABP suite.

I'm sharing the updated Blazor Suite templates. You can also update them on your side
