continueToOriginalDestination not working correctly

[Pepijn de Geus]

Hi all,

I'm working on a website were the customer can enable a splash page that will 
be displayed once per session to every visitor entering the site.
To achieve this, I've added a small session check with a to my BasePage, which 
is the parent of all webpages:

if (!getSession().isSplashShown()) {
    SplashData splash = em.find(SplashData.class, SplashData.ID);
    if (splash.isEnabled()) {
        throw new RestartResponseAtInterceptPageException(SplashWebPage.class);
    } else {
        getSession().setSplashShown();
    }
}

This works like expected; the user is redirected to the URL the SplashWebPage 
is mounted on.
On the SplashWebPage, which does not extends BasePage, I've added a 
AjaxFallbackLink like this:

session.setSplashShown();



add(new AjaxFallbackLink<Void>("close") {
    private static final long serialVersionUID = 1L;

    public void onClick(AjaxRequestTarget target) {
        if (!continueToOriginalDestination()) {
            setResponsePage(HomePage.class);
        }
    }
});

Clicking this links does not work. The log tells me:

"ClassName=org.apache.wicket.protocol.http.WebResponse;MethodName=redirect;....|Redirecting
 to "
(nothing after 'to', only a space)

and the AJAX response reads:

<ajax-response><redirect></redirect></ajax-response>

I was able to solve this issue by either:
- Changing the link to a non-ajax one
- Mounting the SplashWebPage on a path 'deeper' then the one the user 
originally tried te open, such as "/splash/work/please". The user is then 
redirected to "../../" correctly.

It this a bug in Wicket, or am I doing something stupid?

Thanks in advance,
Pepijn
