Hi Adam,
I've found that programmatically changing the selection using the tree
controller's -setSelectionIndexPath(s): will always send the
NSOutlineViewSelectionDidChangeNotification, you might want to have a

I hooked it all up and now the OutlineView displays content, but the
exact same "out of sync issues remain"
The GUI representation of the selected row (which is always correct)
is not noticed by the TreeController under certain rare conditions. A
removal of an item and then an undo for instance.

I think the big problem I am having is that an OutlineView doesn't
always accurately update its index paths to match the selection the
GUI is displaying. So I dont have accurate information to pass onto

Have your tried binding the tree controller's @"selectionIndexPaths"
binding to a variable in your model object?
I havent tried it but it seems that you can do this in IB and then get
the model to observe the bound instance variable and you cab then see
each time the variable changes. Not s
