[Wicket-user] ending a response

[Vincent Jenks]

I'm convinced that I saw an example of what do to when one would like to end the response of a page and redirect to another...but I can't put my finger on it...so here's my problem:

In my page I'm testing for the existence of an object...if it doesn't exist I'd like to redirec to another page...but it appears to continue to try and render the page...which throws a NullReferenceException (obviously) because my object is null:

        //get cart from session
        final ShoppingCart cart = ((UserSession)getSession()).getCart();
       
        if (cart == null)
            setResponsePage(new EmptyCart());

I want the page to stop rendering and redirect to EmptyCart....

Thanks!
