Hello List,
Can someone tell me how to expand the root node in an NSOutlineView (bound to an NSTreeController, managing entities) ?
With "rootNode" being the topmost NSManagedObject in the hierarchy (i.e. having a "parent == nil" predicate), [treeView expandItem: [treeView rootNode]] simply does nothing and I think I'm missing out one something basic here...
Thanks in advance for any helpful input !
Alain
