Hi Simon, I set a breakpoint before the RENDER_RESPONSE phase and inspected FacesContext.context.currentView.viewRoot. The property "childrenList" is null. But it's also null if I use external facelets (where everything works fine). So I guess I'm not inspecting the right object. So my (propably stupid) question is: how to inspect the component tree?
