I just wondered why it was NSTreeControllerTreeNode rather than
NSTreeNode. I'm just naturally wary of solutions beginning "class-dump
shows..."!

Splendid!

I just treat everything at the top level as a group item:
- (BOOL)outlineView:(NSOutlineView *)outlineView isGroupItem:(id)item
{
return ([outlineView parentForItem:item] == nil);
}

Best wishes,
Hamish
