I am using Cocoa bindings to display the objects of a certain entity
in an NSPopUpButton. (It sets a relationship for another entity--like
the "Chef" menu in the Core Recipes example.)
Currently I have the standard Cocoa bindings setup: "content" bound
to "MyNSArrayController.arrangedObjects", "contentValues" bound to
"MyNSArrayController.arrangedObjects.name". This works fine.
I want to add one more item to the NSPopUpButton: "Edit...", which
would open a sheet to edit the entities represented in the pop-up
button. (Again, akin to allowing the user to not just select a chef
but edit them.) I'd capture such a selection and display the sheet.
Obviously the existing binding to NSArrayController won't work.
What's the best way to replace this binding? So far I've tried the
"mixing static and dynamic" technique described by mmalc:
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html
But I'm hopelessly lost--I don't know how to combine that technique
with array controllers and bindings to boot! Any advice?
