KVO / NSArrayController question

Hi,

I'm using bindings (NSArrayController) for my latest app and it's working great! Using bindings saves so much time!

I have one question, however: I would like to dirty my document whenever any value changes in the array managed by the NSArrayController. So I'm not only interested in changes to the array itself (insertion and removal of elements) but also in the modification of any value of any object in the array (modification of instance variables of the objects in the array). I have been searching the list archives and the documentation on this and I guess the addObserver:forKeyPath:options:context: method will do the trick. However, I'd be interested in every possible keyPath available so I was wondering if there is a simpler approach of observing all keyPaths at once for all objects in the array managed by NSArrayController.

Thanks in advance!

Peter
