Hi list,

I'm using the NSCollectionView to present some my custom data. I'm using a
NSMutableArray which bind to the ArrayController to provide data to the
CollectionView.

Every time I'm using the willChangeValueForKey and didChangeValueForKey to
update the GUI.But some time the NSCollectionView will crash . It's really
wired . I haven't used any core Animation features in the IB.

The crash reoport :

I have no idea how it works inside the CollectionView . Could anyone give me
some clue of this bug?? or just prevent the collectionView coreAnimation
features?


Thanks in Advance.

Best Regards
