You may want the collection from which you build a menu to be a Set because you don't want to have repeated entries in a menu, and you'd want nil to be there if your field can be empty. When the menu items are automatically generated, it'd be nice to be able to do Whatever buildMenuFrom: (myCollection asSet add: nil; yourself). IMO this would be more elegant than doing myCollection asSet asOrderedCollection add: nil; yourself, or any other way to ensure the elements are unique and the collection includes nil. 2011/5/20 Henrik Sperre Johansen <henrik.s.johansen@veloxit.no>

Huh? How does a Set figure into that?
