Hi Roland,
Can you reliable reproduce this problem? If so, can you please log a
bug, including your test application (or a link to download it). Or,
ideally, if you have source code that can be compiled that makes
things even easier to debug.

I'm having an NSOutlineView Assertion Failure on collapse if the

item is a child (or child of child, etc) of the item that is being

all the
related posts seem to indicate threading is the cause, but my
application
isn't using any threads. I'm using XCode 3.1 and targeting 10.5
(Intel). I
never call reloadData on my NSOutLineView, so it's data should be
constant.
Any ideas?
