I think the java.bean.VetoableChangeListenter would be a good thing in
an helper bean that was populated by an ActionForm bean, but would
violate the API contract for an ActionForm bean. The ActionFormBean is
suppose to accept whatever the actor throws at it, and then perform
validation. This way we can return exactly what they entered for
correction.
