Title: 10.7 added some extra methods to outline views to support drag and drop.

Just copied your way of bouncing it to the secondary delegate if supported.

These methods aren't in the documentation - you need to look at NSOutlineView.h to see them (and they don't appear in the drop down either"

:(
