Ryan,

You mentioned you had a patch for this issue, but I don't see it.

> The getLink methods in HtmlDataScrollerRenderer are called every time the HtmlDataScroller is rendered.  The methods return a transient HtmlCommandLink.  It looks like the transient property is not being honored because I am getting duplicate id exceptions for these links.
> In order to patch it I extended HtmlDataScrollerRenderer and checked for the existence of the links.  This seemed to work for me.  But I still think it should have been ok as it was because the links are being set to transient.
> In my extension of HtmlDataScrollerRenderer I added the following:
> HtmlCommandLink link = (HtmlCommandLink) scroller.findComponent(scroller.getId() + facetName);
> if (link == null) { // create link and link's children and add link to scroller .... }
> return link;
> The Faces view is being stored in the session.  Not sure how transient property disallows Components to be stored in the session along with the view tree.
