Hi,
Quick question: If my custom NSView exposes a binding called 'blah' why
must it be KVC compliant with that key? Do not key value observations
arrive via observeValueForKeyPath to the view and when the view changes
a value, it uses setValue:forKeyPath: on the controller? What is the KVC
compliance for?
I've also noticed in debugging that the getBlah method gets called after
the observeValueForKeyPath happens. This is related to above obviously
since KVC compliance would be needed to call getBlah. But why is this
happening?
