Invalid cast of CPListItem to CPListImageRowItem
As a continuation of #9996 here is a new issue.
Steps to Reproduce
- Use below SceneDelegate as a CarPlay scene delegate
- Load the app, and tap on an image of the horizontal row
- Get the exception
Expected Behavior
CPNowPlaying should be pushed to the stack and shown.
Actual Behavior
Exception:
Unable to cast object of type 'CarPlay.CPListItem' to type 'CarPlay.CPListImageRowItem'.

If I remove the await Task.Delay() call, it seems to work, but I need to do my async network calls to retrieve the actual data that is shown in the lists.

Example Project (If Possible)
Thanks for the feedback.
Please attach a full sample project, as CarPlay is sufficiently complex to setup a project for, and the configuration might cause different behavior.

Hi @chamons,
Thanks for your quick response. I stripped down my app to the bare minimum: it's a Xamarin Forms app, with CarPlay side. https://github.com/janwiebe-jump/carplay-repro
The one thing you need to do is to have a provisioning profile with the carplay entitlement enabled, and set you own provisioning profile and signing certificate in the options. When you launch the mobile app, you only see a Welcome message. The CarPlay app shows a CPListTemplate with a row with 4 images. Tapping one of the images triggers the Exception. Please let me know if I can be of further help.
Thanks for looking into it!
