I\'m trying to achieve something that should be simple and fairly common: having a bindings populated NSPopupButton inside bindings populated NSTab
You can try this FOUR + 1 settings for NSPopUpbutton:
In my example, "allPersons" is equivalent to your "Authors". I have allPersons available as a property (NSArray*) in File's owner.
Additionally, I bound the tableView delegate to File's owner. If this is not bound, I just get a default list :Item1, Item2, Item3
