Marko,
I use this same situation for a registration page - where you want a User object
as the model, and an additional field on only the action for the confirmed
password.
In this case, I do not implement the ModelDriven interface but have getUser()
and setUser() methods on the Action. The ParametersInterceptor happily walks
into the user object and sets all the values (on the Action and the user
object). What I did have a problem with (a bug is logged), is with declarative
validation in this circumstance.
