Style note: you don't need to do this. [[item representedObject]
isKindOfClass:[GroupNode class]] will work just fine, because messages
to nil return zero or their logical equivalent. So if item == nil,
then [item representedObject] == nil, which means that [[item
representedObject] isKindOfClass:[GroupNode class]] == NO.
Of course, this all works only if the GroupNode class exists. ;-)
