Description Drew Frisk 2015-03-04 15:02:58 UTC
When implementing a custom view on the ListView.Header property, the app will crash when tapping on the view that is rendered in the list.

Replicate: Create a new ListView with Xamarin.Forms and set the header property to any view. Run/debug the application, navigate to the page with the list view and tap on the header item. The app will crash.
