Hello, in my application I have a NSObjectController bound to all controls on the user interface. This works fine so far.

I'm adding the items as part of -awakeFromN...
I have several NSComboBoxes created in Interface Builder, and one created programmatically. The NSComboBoxes created in Interface Builder are perfect. I have their Value bound to the Shared User Default Controller, and when their view is opened they are sitting there with the correct value. Importantly, this value is shown as "normal"...
I have an NSComboBox and I was wondering if there is an easy way to convert it to an ordinary NSTextField? Considering NSCombBox is a subclass of NSTextField, I would think there is an easy way to turn this on/off but I can't figure it out. ...
