What are all the things you can bind to in a NSTableColumn of NSPopupButtonCell?

Question

There are quite a few things you can bind to in a NSTableColumn filled with NSPopupButtonCell, I tried looking around for explanations but couldn't seem to find any.

• What are each of the binding under value selection for? For example, what's the difference between "Content" and "Content Values"?
• Why is "Content Objects" grayed out anyways?
• Why do you bind to the table column instead of the Pop Up Button Cell? The binding options available for Table Column containing a TextCell is also different. How is that accomplished?

This should help for general explanations of the bindings http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/CocoaBindingsRef/BindingsText/NSPopUpButton.html#//apple_ref/doc/uid/NSPopUpButton-DontLinkElementID_801

For help with binding an NSPopupButtonCell and Core Data check out my tutorial at: http://www.themikeswan.com/blog/?p=81 It will also give you an idea of how the bindings would work for non - Core Data stuff as well.
