outlineViewSelectionDidChange not called

I have an NSOutlineView column bound to an NSTreeController. When I
remove an object from the TreeController the row representing the
deleted object disappears and OutlineView selects the next row, but
does not send a notification to the delegate method
outlineViewSelectionDidChange. When I manually change the
OutlineView's selection with the mouse or keyboard
outlineViewSelectionDidChange gets called just fine. I update some non
controller bound GUI controls when the selection changes and I need to
know when to do this.

On a separate but related note, when I add an object to the
TreeController is there away to get the OutlineView to automatically
select the new row?

Any help with this would be much appreciated,
Adam
