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 look here

http://www.wilshipley.com/blog/2006/04/pimp-my-code-part-10-whining-about.html

in particular the -indexPathToObject: method, which allows you to write things like this:

[treeController setSelectionIndexPath:[treeController indexPathToObject:anObject]];

which then send the note. In 10.5 the NSTreeNode has an -indexPath method, but (AFAIK) there's still not an out-of-the-box way of taking an arbitrary object in your model and getting its indexPath in the tree. I've requested an enhancement : rdar://problem/5832408

Happy hunting,

Jon
