-----------------------------------------
Well, I worked all day on trying to duplicate the exception in a simpler test
case and ended up by dumb luck fixing the problem instead. Here is the patch:

//This is where to components with the same id are in the tree,

- inputCalendar.setId(facesContext.getViewRoot().createUniqueId());
+ inputCalendar.setId(inputCalendar.getId()+"tempId");
inputCalendar.getChildren().add(inputText);
I was suspicious of the createUniqueId() method of making a temporary component
id so I changed it so it does not use that method to create a temporary id
anymore. It has fixed the problem in my case which leads me to believe that
perhaps the JSF-RI must be using createUniqueId to help detect duplicate ids in
some way or maybe to help restore the tree. Either way it works now for me and
I think that perhaps this solution may be better than the createUniqueId
solution anyway.
The other issue brought up in here is the lack of duplicate id detections in
MyFaces. Perhaps that should be addressed in another issue?
