For the type of design that you are using, I would recommend placing
your own bean in the session scope, and then using the Actions to
populate it from the incoming ActionForms. This gives you a chance to
vet the input before it placed onto the bean you will be using to update
the business model.

If this is part of a workflow, you can use the bean you have placed in
the session scope to update any outgoing ActionForms with the current
values. This would allow you to use request-scope ActionForms without
bothering with any hidden fields and so forth.
