Application crash on setting icon on toolbar item #25534

jdarwood007 · 2024-10-25T20:28:38Z

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

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

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.

jdarwood007 · 2024-11-01T15:59:56Z

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.
