Wicket & Portlets : content-type problem

[Pierre Goupil]

Hello,

I'm currently facing a problem with a simple code. I'm trying and display a
YUI Carousel but my portal (eXo Platform) gives me an error :


exception returned by processAction() or render() methods
<java.lang.IllegalStateException: the content type has not been set before
calling thegetPortletOutputStream() method.>


Here is the code, which works in a servlet context :

List<String> list = Arrays.asList(new String[] { "images/bangkok.jpg",
"images/hk.jpg",
                "images/jakarta.jpg", "images/sgp.jpg",
"images/neuschwanstein.jpg",
                "images/hongkong.png", "images/singapore.png" });


        add(new YuiCarousel<String>("carousel", list)
        {

            @Override
            protected Component newPanel(String id, String object)
            {
                return new ImagePanel(id, object);
            }
        }

I've seen several people having the same problem on the Net but was unable
to find a solution. Any help would be greatly appreciated.

Regards,

Pierre
