Ouch, maybe it's time to upgrade to 1.2....though I'm supposed to launch this app in a month and I don't want to use a beta or RC in production.

yeah thats 1.2

in 1.1 i guess what you can do is create your own runtimeexception that takes a page, override onRuntimeException in requestcycle? application? and return that page from that method. that should work although im not sure.

throw new RestartResponseException or throw new RestartResponseAtInterceptPageException depending on your needs.

you pass in the page you want to restart at via exception's constructor

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!
