observing a controller for changes

I have a tableView with an arraycontroller. Basically
I query a database for stuff, create the
NSMutableArray and set the content of the tableView
controller to the array. Works great.

I am stumped to know how to observe if the user makes
any changes to the table. I was checking
http://homepage.mac.com/mmalc... if there was anything
there..

basically what I want to do is to set my view as dirty
and enable a save button if the user changes anything.

Any help pointing me in the correct direction would be
appreciated.

Ted
