I want to bring up another issue. The default behavior of RequestProcessor is to save everything into a new ActionForm then do the validation. If token is invalid, why should we bother populating the ActionForm at all? Regards, PQ "This Guy Thinks He Knows Everything" "This Guy Thinks He Knows What He Is Doing"

What you describe would have to occur if the user clicked the submit button twice. So, use js to prevent the double clicking and tokens to be sure the form is not submitted twice.
