Well, or if you use it for something else. In my case the model backs up a
list of items. The
list has a PagingNavigator whose isVisible() returns its result conditional
on the number
of pages  (zero=invisible).  

The problem is that the isVisible() method gets called on every
(ajax)request regardless of
whether its component is added to the RequestTarget or not.
