To get it to observe changes in the array's objects you need to have someObject conform to the KVC indexed accessor pattern which is described in the "Key Value Coding Programming Guide".

This is not accurate. It is not *necessary* for 'someObject' to implement the indexed accessors. You must simply modify the array in a KVO-compliant manner. The most reliable way is typically to use the proxy returned from 'mutableArrayValueForKey:'... See <http://homepage.mac.com/mmalc/CocoaExamples/controllers.html> -- "Programmatic modifications to arrays not noticed by table view".
