Oh, I see... thanks!  I didn't realize it was a subclass of 
NSArrayController; I was going under the assumption its selection 
binding was the same as that for NSObjectController (which from 
reading the documentation I now realize wouldn't have made sense even 
if it was true).

I fixed my binding as per your suggestion, and have now fixed the 
problem.


Thanks again,

Sam
