I honestly don't know why people use the approach of having a hidden field on a re-entrant form to indicate whether it should be validated or not. I have used re-entrant forms for years without such a thing. How? Quite simply there are two phases to a form - GET, which requests a form from the server, and POST, which sends a form to the server. It is therefore quite obvious that I validate on every POST. Simple, isn't it?
