In iOS, calling .Clear() on an ObservableCollection bound to a listview causes a nullref

Open edgiardina opened this issue 3 years ago • 0 comments

Description

I receive the following exception which appears to be thrown from the iOS internals (Android is fine) when clearing a listview's ObserableCollection binding

[0:] System.NullReferenceException: Object reference not set to an instance of an object.

**System.ArgumentOutOfRangeException:** 'Specified argument was out of the range of valid values. (Parameter 'index')'

I receive a few exceptions like **System.ArgumentOutOfRangeException:** 'Specified argument was out of the range of valid values. (Parameter 'index')' in this as well.

Steps to Reproduce

  1. Create file -> new .net maui app
  2. Add a Simple listview to the mainpage xaml
  3. in the codebehind create a simple ObservableCollection list
  4. Bind the Listview to the observable collection
  5. Clear the observablecollection with .Clear() via a button event handler or the like.
  6. Run project on an iOS Sim and click the button
  7. Witness a crash.
