I am still having problems even though I am using the additional
count key path.
This happens if you implement an indentation method on your tree
structure (outline view). If you then indent a node and use undo
(core data), the same wrong index exception occurs.
I have not been able to find a complete way to work around this
problem yet.

The bug is not that serious though. You can solve this by
implementing a count method for the count key path of the
NSTreeController's attributes.

Use Core Data and NSTreeController. This is what they're designed

10.4.3 introduced a bad regression bug in NSTreeController. I
wouldn't recommend using it until that's fixed, hopefully soon in
10.4.4!
Best wishes,
