Unable to find OverlayLayer from given TopLevel #596

Closed BuLuoPiaoYu closed 1 month ago

BuLuoPiaoYu commented 4 months ago

Describe the bug When I create a MainWindow form and inherit from my custom form class AvaWindow, calling ContentDialog.ShowAsync() within it raises the following exception: "Unable to find OverlayLayer from given TopLevel".

Screenshots

Desktop/Platform (please complete the following information):

OS: Windows 11
FluentAvalonia Version [2.1.0-preview6]
Avalonia Version [11.1.0]

Here is the code Style and Code.zip

I got a similar exception on Android when tapping on FAComboBox:

Unable to create IPopupImpl and no overlay layer is found for the target control

Test with many combinations and the last working combination is

Avalonia(.*): 11.1.0-beta1
FluentAvalonia: 2.1.0-preview5

Bumping either will bring the exception for me.

Looking at changes made between Avalonia 11.1.0-beta1 and 11.1.0-beta2, I noticed this commit has changed Android TopLevel significantly. Not sure if this is related.

You need to make sure your TopLevel (Window or otherwise) has a Style/ControlTheme that has the VisualLayerManager, which is where all the adorner and overlay pieces come in.
