What is it crashing with?? I.e. what signal? SEGV?
Have you used the debugger on it ??
If you are getting SEGV's maybe the problem is that you have a
retain/release issue?
I.e. some of the objects within the NSOutlineview aren't being retained
and hence
later on when you go and access it the app crashes??
Just some ideas..

Hi,
I have an outline view that represents relationships of data. I have it
so
that you can traverse the relationship graph. When you have stepped
into the
relationship hierarchy so that you are now looking at the relationships
of
the first relationship it recursively calls the methods [NSOutlineView
_expandItemEntry:addIntoExpandSet:expandChildren].
Eg
e1
| r1 relates to e2
| r2 relates to e3
e2
| r2.1 relates to e1
e3
When expanded when it crashes the tree looks like this.
e1
| r1
|-- r2.1
|---- r1
| r2
e2
| r2.1
e3
Is this a bug with NSOutlineView in that you are not able to show the
same
object in the heirachy twice?
Any info on this would be greatly appreciated.
Regards,
Greg
