System.InvalidCastException: Unable to cast object of type ' XXXX' to type 'YYYY' #14453

Current behavior

Hello, our project uses the c# language to develop the Uno framework + Gtk + Skia running on the Linux platform project,
and it is always triggered occasionally when InitializeComponent() is executed

System.InvalidCastException: Unable to cast object of type 'XXXXX' to type 'YYYYY'.””The following is an error message for one of them." ---> System.InvalidCastException: Unable to cast object of type 'System.Double' to type 'Windows.UI.Xaml.Input.XYFocusKeyboardNavigationMode'.

Can you provide a repro please?

sushuying521 · 2023-11-17T09:08:36Z

Xaml：

<Grid >
    <Popup x:Name="m_Popup" Height="72" Width="800">
        <Grid Background="#FF323232"  Width="800" Margin="72,0" MinHeight="72" >
        <TextBlock Margin="24,0"
                   HorizontalAlignment="Stretch"
                   VerticalAlignment="Center"
                   Text="{Binding StatusText}"
                   Foreground="White"
                   FontSize="{StaticResource TouchPanel.FontSize.Medium}"
                   TextWrapping="WrapWholeWords"
                   TextAlignment="Left" />
         </Grid>
    </Popup>
</Grid>

it is always triggered **occasionally** when InitializeComponent() is executed

jeromelaban · 2023-11-17T21:04:28Z

Thanks. Make sure to provide all the details that are requested when creating a template, particularly the uno version that you're using.

MartinZikmund · 2023-11-20T16:54:20Z

Are you using XYFocusKeyboardNavigation anywhere within the code?

MartinZikmund · 2023-11-20T17:01:31Z

@ebariche Could this be theoretically related to your changes?

Youssef1313 · 2023-11-20T17:02:53Z

I have seen it today in CI:

https://dev.azure.com/uno-platform/Uno%20Platform/_build/results?buildId=102402&view=logs&j=6d871ad7-2a7e-50b7-2020-9e22d4075df1&t=63c7d45e-2e27-5d4f-a2d8-bb7b8105683e&s=71fd53b2-b039-5dc2-9015-d1e3f7eed8d5

Happened for PR: #14476

ebariche · 2023-11-20T17:25:07Z

@MartinZikmund I doubt so !

jeromelaban · 2023-11-21T13:44:15Z

@ebariche this looks very similar to #14489. If people have been using the latest dev bits, though none of them have confirmed that they are, this would point to a change in dependency object.

Youssef1313 · 2023-11-21T13:50:20Z

@jeromelaban I think some of the recent changes (specifically related to performance) assumed that certain code paths are only run in the UI thread.

Could it be something running in a different thread causing a race? In the stacktrace in the original post here, there is IntegrationTestPlatform in the stack trace. That would also explain why there is no 100% reliable repro.

jeromelaban · 2023-11-21T13:52:53Z

It may, indeed. We do not have UI Thread checks in DependencyObject, but it may be interesting to enable them to validate if that's the issue.

MartinZikmund · 2023-11-21T14:39:00Z

@sushuying521 Are you by any chance doing some asynchronous, non-UI thread work in your app by any chance?

Youssef1313 · 2023-11-21T16:01:22Z

#13963 might be related. It's one of those performance optimizations that rely on code properly executing in the UI thread.

If GetPropertyType is accessed by two different threads, bad things can happen.

sushuying521 · 2023-11-22T09:43:06Z

Thanks. Make sure to provide all the details that are requested when creating a template, particularly the uno version that you're using.

<PackageReference Include="Uno.UI" Version="4.9.17" />

sushuying521 · 2023-11-22T09:44:59Z

Are you using anywhere within the code?XYFocusKeyboardNavigation
This is not used in our code

Youssef1313 · 2023-11-22T10:01:40Z

@sushuying521 Are you able to upload a project where this happens?

jeromelaban · 2023-11-22T12:58:41Z

If this is an error this is reported in 4.9.17 as well, this is likely not caused by recent changes. This may be caused by some unknown race condition.

Youssef1313 · 2023-11-28T06:36:45Z

@sushuying521 Do you have subscription to Unloaded event anywhere in your code?

Youssef1313 · 2023-11-28T10:12:53Z

@sushuying521 Also, are you using any RadioButtonss in your code (not RadioButtons). I mean this:

uno/src/Uno.UI/Microsoft/UI/Xaml/Controls/RadioButtons/RadioButtons.cs

Line 21 in f3cc757

public partial class RadioButtons : Control

In that case, #14599 might fix it.

Youssef1313 · 2023-12-19T17:31:56Z

@ebariche @jeromelaban I think this should be fixed and can be closed?

jeromelaban · 2023-12-19T17:57:06Z
