You could certainly bind the combo box's "value" binding to a string property in your data model, whose setter created a new dictionary when necessary. I'm not certain, though, how you'd be sure the user typed a new "Name" for the purpose of creating a new dictionary or just mistyped an existing one. Alternatively, use a pop up menu instead, with a "New XXX..." entry as well as the existing names. That's a more traditional way of doing it, which has the benefit of discoverability for the creation function (unlike the combo box solution). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
