so you seemed to have populated the array controller in a non KVO way... but still, w/o code not to be discussed.
I think that is the problem. If you bind the content of an NSArrayController to someObject.variable, then the controller will be notified of a change in it's content only if you assign a different object (NSArray) to the variable, but NOT if you manipulate the contents of the array. Instead, you need to manipulate the contents of the variable via the controller. So, instead of populating the mutable array directly in your windowControllerDidLoadNib method, try populating it via the controller.
