Hi, Try setting the breakpoint in createView. Facelets differs from JSP at VDL level by loading the view in the createView method, not renderView. If renderView pushes nothing on the client, it should be because the component tree is empty. You could add a PhaseListener to your application and inspect the component tree in the before render phase to be sure that it's what's happening.
