ABP Framework version: v4.4.2

Exception message and stack trace: No one
Steps to reproduce the issue: Generate a Blazor Server App

We been working on a Blazor (webAssembly) app, but we decide migrate to Blazor server, for get better performance on firsts loading.

Right now we been through some problems, one of then is User notify for validations and errors, in web assembly we got a modal windows message that indicate the error or validation. But now on Blazor server, we only get a console log notification in the browser.

Can anybody guide us for get older behaviour?

This is an example:

Before

The user left some field in blank

Now

Right now we got a message for reload page, and the user did not know what's happening

Hi @david.hurtado, please wrap your create and update methods with try-catch blocks and handle exception by yourself (by using HandleErrorAsync method). => https://support.abp.io/QA/Questions/1523/Blazor-Server-ABP-Exception-Dialog-not-shown#answer-7939465b-3349-3100-2cc1-39fd4fd8c78a

And also, you can check the validations (are granted or not) inside of your create and update methods.

private Validations NewSalesmanValidations { get; set; } //validation that used in your create modal

//...

private async Task CreateNewSalesmanAsync()
{
   try
   {
      //if all validation rules are not validated, simply don't do anything  
      if (NewSalesmanValidations?.ValidateAll() == false) 
      {
         return;
      }
   
      await SalesmanAppService.CreateAsync(NewSalesman);
      await GetSalesmanAsync();
      CreateSalesmanModal.Hide();
   }
   catch (Exception ex)
   {
      await HandleErrorAsync(ex); //handles the exception and prevent app crash
   }
}
