Hope we are both talking about a TALES expressions that is part of the 
Action object.

One example was this expression:

     python:object.getPortalTypeName() in ('File', 'Image')

If you add a new type that should also use this Action, you have to 
modify the expression. Its quite hard to do that in an automated way.


Hope that makes my point clearer.
