It should work. Check if you don't have any syntactic mistakes in the Jelly.

By the way. I always thought that exposing the "resource" to the Jelly 
is not very nice. The jelly should only be concerned with what is 
intended for it. As a template it should only know about the model (of 
the view) because it is supposed to be used for rendering.

When you start having ${resource.getFoo()}, ${resource.setFoo()} etc. 
then the template becomes kind of an active entity, a controller. Hence 
the same story as with JSP, where you mix view and controller.
