Well, After some troubleshooting, it looks like the NSView that is attached to the NSCollectionViewItem object is missing its superview. Does any know how this might be possible??
I can see my Subclassed NSView being created. AwakeFromNib works, as does hitTest. The drawRect does get called, but the call to superview fails, because it is set to nil. Just for laughs, I created another NSCollectionView, with NSArrayController, etc, and manually add objects. This works, with the NSViews displaying properly. Is there a way to force NSCollectionView to reload/re-display the NSViews with a proper superview set? bob.
