SignInPage没有看到用户名和密码

Question

我尝试使用ServletContainerAuthenticatedWebApplication实现登录，并将Wicket中的默认SignInPage注册为登录页面。到目前为止一切正常，当我尝试访问受保护的资源时，它会将我重定向到登录页面，但我无法登录，因为SignInPanel内的用户名和密码字段始终为null，无论我在浏览器中输入的内容是什么。我试用了Wicket 8.0.0-M8和Wicket 7.9.0。一些帮助将在此时受到赞赏。

    public class HelloWorldApplication extends ServletContainerAuthenticatedWebApplication
{
    private static String EJB_PROJ_NAME = "rezerva_masa_ejb";

    public HelloWorldApplication()
    {
    }

    @Override
    public void init()
    {
        super.init();
        getComponentInstantiationListeners().add(new JavaEEComponentInjector(this, new AppJndiNamingStrategy(EJB_PROJ_NAME)));
    }   

    @Override
    public Class getHomePage()
    {
        return HelloWorld.class;
    }

    @Override
    protected Class<? extends ServletContainerAuthenticatedWebSession> getContainerManagedWebSessionClass()
    {
        return ServletContainerAuthenticatedWebSession.class;
    }

    @Override
    protected Class<? extends WebPage> getSignInPageClass()
    {
        return SignInPage.class;
    }
}
