mmalc,
Thanks for your help but I just can't get something to work and I think
you might be able to help me. I read your great help page but I still
can't figure one thing out.
OK, I now have two array controllers bound to the same content array.
The main one is controlled by a table--call this combatantController.
The other one is called targetController (I have not added filtering
yet, but I will do so later--for now it just lists the same names as
the original controller does).
First off, I've decided to use an NSPopupButton instead of Combo Box
(makes more sense). What I need to happen is when I choose a name from
the Popup I need the shield rating to be displayed in a text field for
the Combatant (which now happens to be a target) chosen in the Popup.
The problem is that I cannot seem to get this to work. I just don't
know what I should bind to what in the Popup's bindings. The shield
rating text field has been bound to selection.shieldRating as you
suggested (of the targetController). But I can't get the popup to set
the selection index of the array controller and so the shield rating
text field always shows "No Selection".
How do I setup the bindings to get this work properly--so that choosing
a target name in the Popup changes the selected object in the
targetController?
Thanks so much,
Kent!

I *think* you should be able to do this using a custom array
controller that uses the same content array as the first, but which
filters out its (the first's) selection (make an appropriate binding)
-- for an example of filtering see:
<http://homepage.mac.com/mmalc/CocoaExamples/controllers.html>
Now, based on the name chosen in that combo box, another NSTextField
will display this second combatant's shield rating variable value.
That will simply be selection.shieldRating (FilteredArrayController)
