Hi, Laurent. I realize this is quite old, but I have been wrestling with
NSRuleEditor myself for a while. The main difference between NSTableView and
NSRuleEditor is that NSRuleEditor is more accurately understood as a tree or
network whereas NSTableView is a multi-dimensional array, [rows][columns].
As you change the selections in the NSRuleEditor it re-queries the delegate
for the display values for the children. When I diagramed the architecture
of my NSRuleEditor as a tree/network, it made a lot more sense. Start with
the root as nil.
Hope this helps.
