Re: NSReponder chain and controllers

NSArrayController isn't an NSResponder, so you can't add your 
subclasses to the responder chain.  I think the problem is that you 
should be using NSWindowController and NSViewControllers to handle 
menu actions, not NSArrayController.  Those objects can be added to 
the responder chain so you don't have to worry about dispatching 
anything in your code.
