MAUI Blazor for Windows: PushModalAsync-Issue

Open reinhardlackner opened this issue 3 years ago • 3 comments

Description

In a MAUI blazor app, it is not always possible to open a content page as modal dialog in Windows.

  1. Start MAUI Blazor App: image

  2. Click on Button "Open modal page" (which calls a ContentPage) - Code: image

  3. Unhandled Win32 Exception appears: image

Steps to Reproduce

  1. Create .NET MAUI Blazor-App

  2. Add new .NET MAUI ContentPage (XAML) image

  3. Add new button which opens the newly created modal dialog page: image

4a) Case ERROR SHOWN: After clicking on the button, the modal ContentPage sometimes does not appear... Win32 Exception is shown instead: image

4b) Case NO ERROR SHOWN: After clicking on the button, the modal ContentPage appears correctly: image Click on "Close me" - Executed code: await Navigation.PopModalAsync();

Click on the button again (1) and click anywhere in the white background (2), before the modal page appears - Win32-Exception appears: image

Hi @reinhardlackner , can you show the full stack trace of the exception when this happens? That would help us route this issue to the appropriate team.

Hi @reinhardlackner , can you show the full stack trace of the exception when this happens? That would help us route this issue to the appropriate team.

@Eilon Unfortunately I was not able to add a debugger after the crash. image

Alright thank you for the info, we will try to reproduce this and investigate.

Hi @reinhardlackner , I was able to reproduce an exception in this app when I specifically attach native debugging and catch all exceptions. I then get this error, but I'm not sure if it's the same error as you're seeing:

The same exception that I saw also happens without any Blazor. Lots of various Win32 (or C++?) exceptions, but they are all first-chance, so without a debugger you can't see them.

Verified this issue with Visual Studio Enterprise 17.7.0 Preview 2.0. Not repro on Windows platform with sample project. MauiAppBlazorModalBug_20220809.zip image

Hi @reinhardlackner. We have added the "s/try-latest-version" label to this issue, which indicates that we'd like you to try and reproduce this issue on the latest available public version. This can happen because we think that this issue was fixed in a version that has just been released, or the information provided by you indicates that you might be working with an older version.

You can install the latest version by installing the latest Visual Studio (Preview) with the .NET MAUI workload installed. If the issue still persists, please let us know with any additional details and ideally a reproduction project provided through a GitHub repository.

This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.
