org.apache.wicket.markup.html.form.persistence.IValuePersister
Wicket users and developers should not need to care about where or how form values are saved. An implementer of IValuePersister persister is responsible for storing and retrieving FormComponent values. Different means of storing values for form components may be implemented. CookieValuePersister, for example, uses an HTTP cookie to persist the value of a form component. Other implementations may instead persist form values to server-side storage for security reasons. @author Juergen Donnerstag @author Jonathan Locke @deprecated remove in 1.5

        // Note: if that is true, values may remain persisted longer
        // than really necessary
        if (formComponent.isPersistent() && formComponent.isVisibleInHierarchy())

          final IValuePersister persister = getValuePersister();


          // Retrieve persisted value
          persister.load(formComponent);
        }
