问题 I am trying to sign into my application. First I throw the RestartResponseAtInterceptPageException (this is in a WicketPanel on my BasePage): add(new Link<String>("signin") { @Override public void onClick() { throw new RestartResponseAtInterceptPageException(SignIn.class); } }); The SignIn Page class contains a form (an inner private class) for the sign in, with the following submit button: add(new Button("signinButton") { @Override public void onSubmit() { final User user = model.getObject()

问题 I'm a Wicket newbie. I wonder if someone could help me with the following: I have: .centredtab{ margin-left: auto; margin-right: auto; } and: <form class="centredtab"wicket:id="questionform"> but the class centredtab for the form is not being rendered. Is there a method in the Wicket API to ensure that this class attribute will be rendered in order that the form is centred? Thanks! 回答1: Wicket simple attribute appender to rescue you see here http://wicket.apache.org/apidocs/1.4/org/apache

问题 I have a Wicket AuthenticatedWebApplication which has several pages and features that need to be reused in a new AuthenticatedWebApplication that I have to develop. I am using Wicket 1.4, Spring and Hibernate. Both applications will even share the same look (except for Application logo) which is now implemented in a base page. Has anyone had a similar experience? I definitely don't want to recur to copy-paste code because the common functionality implements a workflow process which can and

问题 I would like to implement a countdown timer in Wicket. I have a clock class: public class Clock extends Label{ private static int time; public Clock(int mytime,String id,String message){ super(id,message); time=mytime; this.setDefaultModelObject(message); } public int getTimeLeft(){ return time; } public void decrement(){ time--; } } and here I attempt to update it every second: clock.add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(1)){ protected void onTimer(AjaxRequestTarget target){

问题 I have a wicket project with lambda expressions. On one page when user clicks on back button my application crashes on: java.lang.IllegalArgumentException: Invalid lambda deserialization at x.y.z.MyPage$3.$deserializeLambda$(MyPage.java:1) In the page class (where I return) I'm using lambda expression for implementation of this interface: public interface Localizator extends Serializable { String getLocalizedString(String key); } And the lambda: protected void someMethod() { localize((String

问题 I get a Caused by: org.hibernate.SessionException: Session is closed! error when I click on a link before the whole page is loaded (or my guess, just inside the active hibernate session). All of my DAO classes are subclassing GenericDAO where i got this method: public Session getSession() { if (session == null || !session.isOpen()) { session = HibernateUtil.getSessionFactory().getCurrentSession(); } return session; } This is called from: public void beginTransaction() { transaction =

问题 I need to modify the position of the modal window before it gets displayed in the middle. I have a ajaxbutton which will open the modal window. In the onClick method I tried something like... target.appendJavaScript("$(\".wicket-modal\").css('width', 888+'px');"); or target.appendJavaScript("$(\"[id^=_wicket_window]\").css('top', 100+'px');"); and some more variations of it... It seems I can't manipulate the position of the ModalWindow before it gets displayed. But I can manipulate the

问题 Interface IColumn contains a method getSortProperty(), which returns a value of any type S. How the name can be of type other than string? /** * Returns the name of the property that this header sorts. If null is returned the header will * be unsortable. * * @return the sort property */ S getSortProperty(); http://ci.apache.org/projects/wicket/apidocs/6.0.x/org/apache/wicket/extensions/markup/html/repeater/data/table/IColumn.html In wicket older version 6: PropertyColumn<SomeClass> column =

问题 I'm using wicket 6. My application is based on WebPages created with pageParameters in the constructor. I'm using also a pageParameter country that is a path-parameter defined with: mountPage("/${country}/pagepath", MyPage.class); I have many statefull forms in every page. I'm now trying to handle the case when the session expires (to reproduce this scenario I delete or modify the jsessionid cookie). After that I click a submit button in a page and I'd expect wicket to understand that the

问题 I am taking my first steps with Apache Wicket and ran into the following problem. I have a ListView that displays a "delete" link right next to its entries. When the delete link is clicked, the entity represented by the list item is deleted from the database but the list itself does not get updated until I reload the page manually in the browser. IModel<List<SampleEntity>> sampleEntityListModel = new LoadableDetachableModel<List<SampleEntity>>() { @Override protected List<SampleEntity> load()
