How to get a NSPopUpButtonCell bound to a CoreData attribute?

Subject: How to get a NSPopUpButtonCell bound to a CoreData attribute?

I have a NSTableView with its columns bound to a array controller backed by CoreData.

I would like to change one of the free form text cells to a lookup. I have added NSPopUpCellButton and linked that to a menu.

If I do not bind the column the menu options for the table are displayed, but the column value is not displayed one a menu choice has been selected.

If I bind the column the menu will not popup! I don't mind what the entity attribute is, but would prefer it to be the index of the selected menu item. How do I get the menu selection to update the entity attribute and the column to display the selected menu text?


Thanks Martin
