Post some code. How is clicking the button adding to the array?

Hi everyone,
I have a Container object that has a Characteristics object which,
in turn,
has a NSMutableArray ("myarray") object. I also have a
ContainerController
object that I want to set up to observe changes to the NSMutableArray
object. In the ContainerController, I have a line of code:
[container addObserver: self forKeyPath: @"characteristics.myarray"
options:
0 context: NULL];
I have a NSArrayController object set up to manage changes by a user
to the
NSMutableArray object through a table view. I also have a button
that, when
clicked, adds a row to the table. Such a change to the array does
not seem
to be sending a "changed" message to the observer (the
ContainerController
object). I am pretty sure that I've followed the KVO criteria
regarding this
array object. How should I set this up so that my
ContainerController object
will be notified when an element is added to the array?
Thanks,
Jason
