Description

If I have a collection view (with no binding involved) that I've set the ItemSource to in the constructor of a page. Then that ItemSource gets nulled out if the page is refreshed via hotreload

Steps to Reproduce

  1. Run the attached app
  2. If you click the button you'll see that strings will get added to the collection view Item Source
  3. change the text on the button inside hot reload
  4. The Collection View is now blank
  5. if you click the button no items get added because the ItemSource is now null

Expected Behavior

The ItemSource should retain the value that was set in the constructor after a hot reload happens

Actual Behavior

The ItemSource becomes null

Basic Information

  • Version with issue: 4.7
  • Tested on Android only so far
