Description

In my environment every subsequent request causes a paginator renders the page links twice.
The links are renderd twice, once by encodeChildren method then by renderPaginator method.
I had to create a simple patch to ignore page links in encodeChildren method.

    public void encodeChildren(FacesContext facescontext, UIComponent uicomponent)
                    throws IOException
    {
        RendererUtils.checkParamValidity(facescontext, uicomponent, HtmlDataScroller.class);

        if (uicomponent.getChildCount() > 0)
        {
            HtmlDataScroller scroller = (HtmlDataScroller) uicomponent;
            String scrollerIdPagePrefix = scroller.getId() + HtmlDataScrollerRenderer.PAGE_NAVIGATION; 

            for (Iterator it = uicomponent.getChildren().iterator(); it.hasNext(); )
            {
                UIComponent child = (UIComponent)it.next();
                String childId = child.getId();

                if (childId != null && !childId.startsWith(scrollerIdPagePrefix)){
                    RendererUtils.renderChild(facescontext, child);
                }
            }
        }
    }
