I'm writing a program which contains an outline view. The data

need to be able to get a pointer to the item's parent so I can find
its key in the case that it is in a dictionary, or its index if its
in an array. Is there any simple way of doing this, or am I going
to have to make a big work around? Any help would be appreciated.
Thanks.
Create a simple NSObject subclass and use that instead of arrays,
dictionaries, etc. The subclass can have a weak reference to its
parent.

I'm not sure if I understand what your saying here. Maybe I didn't
explain my problem very well either? Just in case here's an example:
The data source's method outlineView:outlineView
objectValueForTableColumn:tableColumn byItem:item is called. From
this method I need to get a pointer to 'item's parent in the
NSOutlineView. That is my entire problem. (Sorry for being so cryptic
before.)
