Commands do not Properly Enable Buttons in Release Builds (Android)

[adamjhilton]

Description

When buttons are bound to an underlying command, everything works fine when compiled for Debug. When compiled for Release, the command's CanExecute() method does not properly redraw the button in accordance with its designated style.

This is an Android specific bug. The behavior is the same when running in an emulator and when sideloaded on a physical device.

When compiling for a Windows Machine, the behavior is as expected.

Steps to Reproduce

1. Pull the MauiBugs repo with the test app.
2. Build and run the app in Debug.
3. Play with the buttons under the 'Button Enabling Visualization Bug' heading.
4. When the button is enabled, it displays and behaves correctly.
5. Build and run the app in Release.
6. When the button is enabled, it behaves correctly. But it is not displayed correctly.
7. The Click Count button's text color is the only thing that changes.

Version with bug

6.0.400

Last version that worked well

Unknown/Other

Affected platforms

Android

Affected platform versions

Android 11.0

Did you find any workaround?

I created a second disabled button that draws itself on top of the actual button. I modified the underlying code with an additional flag that the button's IsVisible field is bound to. The command's CanExecute() method always returns true, but the new flag is set appropriately.

Hi @adamjhilton. 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.

Thanks for the update. This is still broken. Sorry that I commented out the controls for this bug. I thought you were done with it. I've commented them back in. Grab the latest of my repo. See the (#10825) section. Everything behaves in Debug. But when I compile for Release and deploy the app, the button never visibly reenables after it's been disabled and then reenabled.

(Side thought: looking at this again, I think that #10825 and #14813 might be the same bug across multiple controls.)

I've updated to the latest version of Visual Studio. Below is the info from the About Microsoft Visual Studio screen:

Still broken on .Net 8 Preview 5.

[jenscski]

Looks like it's fixed in .NET 8 Preview 7

Can this be verified?

[stefanpirkl]

Seems fixed in Preview 7, for the small amount of time I got the release build working. However, Preview 7 introduced new bugs crashing the app on release builds - until I've found workarounds for those, I won't be able to test properly.
