> The org.richfaces.component.DataScrollerPhaseListener adds a phase listener that always searches through the component tree looking for a DataScroller component (to reset the pagination I think), evaluating the isRendered flag on each component.
> I would suggest that, if possible, this should only occur when a DataScroller component is actually present on the page, avoiding the overhead of searching the entire component tree on each request. (Could the DataScroller component store its id in the view root attributes to switch the searching on/ off?)
> Also, the evaluation of the rendered attribute by the phase listener ought to be documented to aid developers.
