I am expecting that when I do [docArray addObject:x] that the array controller will observe the change and do a reloadData on the NSTableView. That isn't happening.

Read the Key Value Coding and Key Value Observing documentation. Your problem is a common one. If you're modifying the bound-to array, you need to enclose the modification with will/ didChangeValueForKey: ... otherwise you're "changing the array behind the controller's back" because you're not sending proper KVO notifications to let it know a change occurred.
