Application crash on setting icon on toolbar item #25534

Open jdarwood007 opened 1 week ago

jdarwood007 commented 1 week ago

Description

My app sets a icon for a tool. The icon binding is inside a view model. The crash only happens with a specific setup and steps. I've linked to a test app that I can reliably cause it to crash.

I compiled the iOS code on XCode 16 on Mac OS Sonoma (14.5) on a M1 Mac. This does not crash Android

At first I thought this was related to the Mvvm tool kit, but I can get it to crash using just the native INotifyPropertyChanged I've included both in my rest repo.

The error I get with this is:

Which seems to indicate that the button_note file is not found. However this works to set it the first time around.

Checking the directory, the file exists, with the appropriate extension:

jeremy@macmini ~ % ls /Users/jeremy/Library/Developer/CoreSimulator/Devices/B0940D78-2ADE-4E0D-9F93-4FE2A0A65412/data/Containers/Bundle/Application/0439438F-E562-4B4F-8843-4AD1F3808A60/MauiApp6.app | grep 'button_note'
button_note.png
button_note@2x.png
button_note@3x.png

I'm unsure if related, but at one point, I did get a sigsegv crash testing this

Exiting early due to double fault.

Steps to Reproduce

From my test repo

  1. Click on 'Go to Add page'
  2. The icon is set properly no error occurs
  3. Click the go back button.
  4. Click on the 'Go to Add page'
  5. App crash occurs on the second call to update the NoteIcon property.

Additional testing

If I comment out the call to SetProperty and have it just set a null, I still get a error.

        set
        {
            noteIcon = null;
            //SetProperty(ref noteIcon, value);
        }

The Fallbackvalue from the .xaml would be calling this

        <ToolbarItem Text="Notes" IconImageSource="{Binding NoteIcon, FallbackValue=button_empty}" />

I've tried to specify a file extension, no change.

I've installed the latest visual studio preview and upgraded to the latest (at the time) .NET 9. It does not crash, but produces the error:

2024-10-28 08:44:41.209437-0700 MauiApp6[17199:3339626] [MauiApp6] IIOImageSource:439: *** ERROR: can't open '/Users/jeremy/Library/Developer/CoreSimulator/Devices/B0940D78-2ADE-4E0D-9F93-4FE2A0A65412/data/Containers/Bundle/Application/0CA9C5C4-75ED-4638-8E41-F981404DCFF4/MauiApp6.app/button_note'  (fileExists == false)

Reverted back to .NET 8 and the crash occurs. This seems to specifically target .NET 8.

In my testing the icon still appears to be updated correctly and changes as expected on the interface if I use a try catch to ignore the null reference.

I am still trying to find a workaround here. This is holding up my app development as I can't reliably get the icon to change as app logic determines it should update.

I thought about adding some logic with a Task.Delay on the OnAppearing call using MainThread.InvokeOnMainThreadAsync. I would then remove the toolbar item and readd it. This resulted in a crash. I did some more testing and found just calling for removing the toolbar item is able to crash the app with similar errors as above

    private void CrashBtn_Clicked(object sender, EventArgs e)
    {
        ToolbarItem? noteBtn = ToolbarItems.FirstOrDefault(x => x.Text == "Notes");
        ToolbarItems.Remove(noteBtn);
    }

I tried to mess with linker settings and no workaround yet.

If I suppress the call with a try/catch, no crash but the icon does not update as expected either.
