 * This StatelessForm is the same as a normal form but with the statelesshint default to true. The
 * form can be newly constructed when the onSubmit of its form or its buttons is called. So you
 * can't depend on state within the page. The only state you can depend on is what was submitted
 * from the browser. So the model of the form or the formcomponents are updated with the submit
 * values.
