public class StatelessForm<T> extends Form<T>
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. Note: Use RepeatingView in the case when FormComponents need to be rendered inside a repeater. See the javadoc of AbstractRepeater for more information.

      getStatelessHint in class Form<T>
      Returns:
      whether the component can be stateless
