[Mono-osx] NSKeyValueObserving with NSCollectionView

[flohei]

Hi again,

In a simple example where I'm binding a NSString to an NSTextField the binding does work in the first place (when the window loads). But when I update the string in code, say on a button click, it does not change the interface. Any ideas on this?
