Most likely your Root's end action forwards to a view. If you use the  
RenderView action-class, it shouldn't do that if the body is set.

I would change the rg actions last few lines to something like this:


$c->res->body($t);
$c->res->content_type('your/content-type');
}

No point in forwarding to end, since that is done automaticly.

If you don't use RenderView, you need to post your roots end action if  
we are to help you figure out whats up there.
