> When you omit <f:view> on a page, you get an exception along the following lines:
> java.lang.ClassCastException: javax.faces.component.UIViewRoot 
> at 
> org.apache.myfaces.trinidad.webapp.UIXComponentELTag.setProperties(UIXComponentELTag.java:99) 
> (this in the 1.2 branch, where we have a UIXComponentELTag.)  The problem is that
> the underlying UIComponentTag has actually associated itself with the UIViewRoot, since
> it's the first component in a page, and passed that to setProperties(), where we try
> to cast it to UIXComponent.   Bad.  We should detect UIViewRoots and throw a
> meaningful exception, something like:
>   "<f:view> was not present on page:  tag XXXX encountered without an <f:view>"
