I would like the action to perform (not fail as validator specifies) but give feedback to the user about the entered data. For example in certain fields you can use a table as a select but override the selection, and other input would be added to the selection. You would want to let the user know that the information was added to the allowed list.
I am doing your other selection in the action class as well. My intermeditate solution, is to extend the ActionForm and add an informational message ActionMessages property and a special tag for displaying any pending informational messages.
