The Form way is a quirk way to do it in the first place. You are not
supposed to update model before validation etc. so you will run into
lots of troubles that way.
Reusemanager simply works like wicket normally works when you validate
and repaint the screen with rawInput values. It just keeps those
components and copies the old rawInput value which was persisted
during incomplete submit.
