Sample repo to illustrate an crash with MAUI-iOS when a CollectionView is on a non-visibile Page and has updates to the groups it's bound to. Scenario mimics logic our company uses in a real world application.
Currently using Microsoft.Maui.Controls v9.0.40.
To reproduce error:
- Run application - should see a 'TODO' group with 'Mow Lawn', and a 'DONE' group with 2 other rows.
- For the 'Mow Lawn' row, tap 'Details'
- Within the DetailPage, tap the 'ACTIVE' button - work item will now be ACTIVE, and the groups will be updated in MainViewModel&MainPage.
- Staying on the DetailPage, tap the 'TODO' button
Running the above on WinUI and Android works flawlessly. Running on iOS results in a crash:
