Of course. Content is being provided by a NSArrayController. And I've 
added an observer to the key "selectionIndexes" of the 
ArrayController. But: I forgot to connect the "Selection Indexes" 
Binding of the NSCollectionView to the ArrayControllers 
"selectionIndexes" in IB. After connecting them together it works 
without errors.

So, thanks for the Tip with the ArrayController, that made me check my 
bindings..
