 * This class can be used to define an 'action' to perform when a form is
 * submitted.
 *
 * An action can be added to a form using the {@link Form#addPreSubmitAction}
 * and {@link Form#addPostSubmitAction} methods. The first can be used to define
 * an action to perform right before the form is submitted (typically used to do
 * some final field updates); the latter can be used to do some processing after
 * the form is submitted (typically used to write back field values to some
 * target object).
