I'm just leaving the UIViewRoot creation and setting of the viewId to
the superclass.
When I debug renderView, I can see that the initial request has the
viewId set to "/view.xml" which is the "real file" I pass during
super.createView. Is that not the correct viewId? If not, where/when
would I set it, and what viewId should I use?
