-----------------------------------------------------------------
Attached is a fix that sorted out this issue in portlet environment. The fix
prevents repeated addition if HTML link component to the data scroller that was
a cause of having duplicate element inside the data scroller component.

> In a portlet environment a non-faces request produces an exception when the
> faces tree is rendered if the faces tree contains a DataScroller component.
> The HtmlDataScroller renderer actually renders its children twice in this
> case, once in the encodeChildren method and once in the encodeEnd method.
> Since rendering of the children is taken care of in encodeEnd I made the
> encodeChildren method a no-op. Also, although the CommandLinks which are
> rendered as children are marked as transient, they see to stick around. I
> put a check in the getLink methods to make sure that the links are not added
> twice. This seems to fix the duplicate id exception, but it might be
> necessary to further investigate why they are sticking around in the first
> place.
