org.apache.wicket.markup.html.form
Class StatelessForm<T>

java.lang.Object
  org.apache.wicket.Component
      org.apache.wicket.MarkupContainer
          org.apache.wicket.markup.html.WebMarkupContainer
              org.apache.wicket.markup.html.form.Form<T>
                  org.apache.wicket.markup.html.form.StatelessForm<T>

Type Parameters:

T - The type of the Form's model object

All Implemented Interfaces:

Serializable, IClusterable, IConverterLocator, IRequestListener, IFormSubmitListener, IHeaderContributor

Direct Known Subclasses:

SignInPanel.SignInForm

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.

Method Detail

process

public boolean process()

Description copied from class: Form

Process the form. Though you can override this method to provide your whole own algorithm, it is not recommended to do so.

See the class documentation for further details on the form processing

Overrides:

process in class Form<T>

Returns:

False if the form had an error

getStatelessHint

protected boolean getStatelessHint()

Description copied from class: Component

Returns whether the component can be stateless. Also the component behaviors must be stateless, otherwise the component will be treat as stateful. In order for page to be stateless (and not to be stored in session), all components (and component behaviors) must be stateless.

Overrides:

getStatelessHint in class Form<T>

Returns:

whether the component can be stateless
