public class PageHTMLForm
extends BaseHTMLForm

A HTML form intended to be used in a jsp page that self-submits. A hidden control is used to determine if the form has been submitted and needs to be validated against external inputs. Otherwise the form validates against its initial state so these forms should be initialised to a valid state to avoid error markup on the initial show of the form.
