Description
TemplateBinding for ICommand not working from within a ControlTemplate on Xamarin Forms iOS whereas it works as expected on Xamarin Forms Android.
Steps to Reproduce
- Bind the ItemTapped Command Property from an extended ListView contained in a ControlTemplate used on a ContentPage
Expected Behavior
Expected Behavior is that the ICommand in the ViewModel is executed which happens correctly on Android.
Actual Behavior
Actual Behavior on iOS is that somehow the ListView.ItemTapped event appears not to run although the ICommand is executed. The result is that the Command Parameters are never passed. The sample app can be used to illustrate this, a breakpoint in ListViewEx.OnItemTapped is never hit.
