It might be of use to remember that changes within an NSMutableArray 
(addObject, remove...) do not by themselves lead tot calling the 
class's observers. I found it useful to bracket the changes in this 
manner:
[self willChangeValueForKey:@"theArray"];
  // changes to the contents of the array
[self didChangeValueForKey:@"theArray"];

Hope this helps.
