Binding and NSPopupButton

I'm using binding on a NSPopupButton, and it works great. I have the 
binding connected to the selected value and using Shared User 
Defaults. The popup menu is used to set a preference. When my 
application is running I can lookup the key and I get the string of 
the selected item in that popup menu. Seeing how the interface will 
be getting localized at some point that string is not really what I 
want stored in the Shared User Defaults. It would be far more useful 
to have the tag of the menu item that was selected. Then once things 
get localized it will still work.

In IB shows binding for the tag but it is disabled. Or should I be 
using a Value Transformer? Does anyone have a nice clean way to do this?

thank for the help
