This is how you can do it with reusemanager:
HomePage:
public class HomePage extends WebPage {
public HomePage(final PageParameters parameters) {
Form<Void> form;
add(form = new Form<Void>("form"));
form.add(WicketSession.get().getReuseManager().rememberOrReuseAndProvideFeedback(HomePage.class.getSimpleName()
+ "tf", new TextField<String>("tf", Model.of(""))));
form.add(new Button("doMemorizeInvalidData") {
@Override
public void onSubmit() {
super.onSubmit();
setResponsePage(OtherPage.class);
setRedirect(true);
};
}.setDefaultFormProcessing(false));
form.add(new Button("doUpdateData") {
@Override
public void onSubmit() {
super.onSubmit();
setResponsePage(OtherPage.class);
setRedirect(true);
};
});
}
}
Reusemanager holder (can be session, can be something else):
public class WicketSession extends WebSession {
/**
*
*/
private static final long serialVersionUID = 1L;
private final FormComponentReuseManager reuseManager = new
FormComponentReuseManager();
public FormComponentReuseManager getReuseManager() {
return reuseManager;
}
/**
* @param request
*/
public WicketSession(Request request) {
super(request);
}
/**
* @return WicketSession
*/
public static WicketSession get() {
return (WicketSession) Session.get();
}
}
