I just ran into the same issue adding groups to a CollectionView. Stack trace: |
|
Still reproducibly with MAUI 8.0.70. We are constantly running into this bug. Would be nice, if someone could have look. |
|
The same issue for me on the prod is reported by Google Play. I'm unable to reproduce it locally. MAUI 8.0.70 |
|
I'm still seeing this bug, which is a bit of a showstopper as it leads to random app crashes. We can no longer deploy Xamarin Forms updates to Google Play, due to lack of support for Android 14. So the fact this is still a MAUI bug is disheartening. Has anyone found a workaround besides reallocating the ObservableCollection? |

Description
Adding groups to a CollectionView sometimes leads to a IndexOutOfBoundsException - see "Log output" for complete stacktrace.
Steps to Reproduce
Link to public reproduction project repository
https://github.com/markusroessler/MauiCollectionViewInconsistencyDetected
Version with bug
8.0.40 SR5
Is this a regression from previous behavior?
Yes, this used to work in Xamarin.Forms
Last version that worked well
Unknown/Other
Affected platforms
Android
Affected platform versions
Android 10
Did you find any workaround?
Recreate the ItemsSource/ObservableCollection instead of adding items to the existing one. Performance will obviously be worse when doing this.
