>  In an included page (or fragment) if a composite component gets used, the CompositeComponentTagHandler
retrieves the logical viewId (context.getViewRoot().getViewId()) first and then gets its physical
URI in order to determine the VDL to use. This is usually not a problem in vanilla JSF applications
or even vanilla Trinidad applications, but in frameworks (such as Oracle) where the viewId
of an included fragment comes into play (iow, the fragment is in context and not the main
page), the PageResolver implementation can no longer return the correct physical URI for the
logical viewId. It merely returns the logical viewId.
>  The problem is further exasperated if the logical viewId of the page does not contain
an extension. As there is no extension available, the VDL returned is the JspViewHandlingStrategy
always. This is disastrous when the page is being rendered using FaceletsVDL.
>  One way to resolve this issue is to cache the physical URI of the page on the ViewRoot's
viewMap and return the cached value whenever the VDLFactory.getVDL() is called for a viewId
that matches the current viewRoot's viewId.
