The specific problem should be fixed now, but investigation did show loads of issues
in the outline view code. We really should try and find somebody to check to whole
class.

Thanks, that indeed fixed the problem I was having. Though, I have found others. I was
expecting reloadItem to redisplay the item as well. This doesn't currently happen
under GNUstep.
I modified the test a little bit to check for this too. I also got the test running on
OSX, and can verify that on OSX, the item is redisplayed. A new one is here:
http://www.eskimo.com/~pburns/rob/misc/Testing-20040701.tar.gz
Also, after playing with the test a bit more I found that if you reproduce the
following steps:
1) open the NSOutlineView test
2) expand the 'wet' item
3) select the 'wet' item
4) check the 'Children' checkbox
5) press the 'Reload Selected Item' button
The contents of the OutlineView will disappear

This problem is caused by the inconsistent use of NSNull in NSOutlineView. The shared
null object is used here for the key nil in object mappings, but sometimes when
iterating over the keys the reverse conversion is not applied.
I changed that and the code is now working for me.
