Hi Quincey,
I did read this page - but I'm not sure it does what I want because it's only 2/3rds of my interface. The master-detail explained there works fine for my items list and to display the selected item's properties but I need the list of items (the master in Apple's example) to be the result of another relationship (the accounts - each account can have zero to many items). So almost as master-master-detail, even though that's a terrible term.
Does that make more sense?
