@LuckyDucko tagging you here as I don't think I can assign you.

@Mous625 all good, ill sort this one out asap, downgrading makes it work?

@LuckyDucko Thank you for your prompt reply.

Just checked, and downgrading to 1.0.1 makes it work if closing the popup using MopupService manually. However, the error does occur if the user attempts to close the popup by swiping down on it.

P.S when I say manually I mean using the await MopupService.Instance.PopAsync() to a button event handler of my own making.

That makes sense, as its an issue with the HitTest function, ill let you know when its sorted 👍

So curiosity got the better of me and I decided to have a look and added the Mopups project to my own. The error was happening when trying to cast a ViewCell to a VisualElement. I'm not an expert by any means, so I just added a try-catch to that section to ignore cast exceptions and it worked without issues. Please note I have no idea whether simply ignoring the ViewCell is the right approach but this may help speed up the process for you. Here is the code:

private static void DisposeModelAndChildrenHandlers(VisualElement view)
{
  foreach (VisualElement child in view.GetVisualTreeDescendants())
  {
    try //<-------- added by me
    {
        IViewHandler handler = child.Handler;
        child?.Handler?.DisconnectHandler();
        (handler?.PlatformView as UIView)?.RemoveFromSuperview();
        (handler?.PlatformView as UIView)?.Dispose();
    }
    catch(Exception){} //<-------- added by me
  }

  view?.Handler?.DisconnectHandler();
  (view?.Handler?.PlatformView as UIView)?.RemoveFromSuperview();
  (view?.Handler?.PlatformView as UIView)?.Dispose();
}

Still getting round to this, just been having issues with my Macbook, so i can't poke where the issues may be, sorry for the delay!

@Mous625 could you provide a sample project for me to work off?

I just tested it then, and it seems to work quite fine on the default project. Perhaps its because you use shell?

Either way, I have a fix in mind, just wanting to get a test case running so I know

---EDIT----

Scratch that, I can probably just add any version of the "Cell" class in for testing

I dont understand why I settled on VisualElement, as this is much more robust if it works

This should be addressed by v 1.0.3

My apologies I forgot to respond as I got bogged down by a new project. This fixes the issue. Thanks.

Hello,
I just stumbled upon a rather unique encounter.
I am currently porting a Xamarin.Forms Application to MAUI. And I'm using Mopups as a replacement of RG.Popup. I'm still getting this error when trying to pop a page with ViewCells. I tried with both 1.1.1 and 1.2.0 nuget packages, but the problem persists.
Then I tried to debug with injecting the master code-base directly into my project and the problem went away.
