sean schofield commented on MYFACES-200:
----------------------------------------

Is this still a problem with the latest nightly build?  <h:dataTable> implementation has been significantly changed and many of the related issues are no longer problems.

>          URL: http://issues.apache.org/jira/browse/MYFACES-200
>      Project: MyFaces
>         Type: Bug
>     Versions: 1.0.9 beta
>  Environment: Windows XP, Tomcat 5/JBoss 3.2.5 (my environment), in general any environment
>     Reporter: Waldek Piszczewiat
>     Priority: Minor

> When I use dataScroller tag with facets, i.e like this:
> <x:dataScroller id="scroll_1"
>   for="dataAssignment"
>   fastStep="#{assignments.layout.list.paginatorFastStep}" 
>   pageCountVar="pageCount"
>   pageIndexVar="pageIndex"
>   styleClass="paginatorScroller"
>   paginator="true"
>   paginatorMaxPages="#{assignments.layout.list.paginatorMaxPages}"
>   paginatorTableClass="paginator"
>   paginatorActiveColumnStyle="font-weight:bold;"
> >
> <f:facet name="first" >
>  <x:outputText styleClass="paginatorLink" value="#{commonBundle.paginatorFirst}"></x:outputText>
>  </f:facet>
>  <f:facet name="last">
>     <x:outputText styleClass="paginatorLink" value="#{commonBundle.paginatorLast}"></x:outputText>
>   </f:facet>
>   <f:facet name="previous">
>     <x:outputText styleClass="paginatorLink" value="#{commonBundle.paginatorPrevious}"></x:outputText>
>   </f:facet>
>   <f:facet name="next">
>     <x:outputText styleClass="paginatorLink" value="#{commonBundle.paginatorNext}"></x:outputText>
>   </f:facet>
>   <f:facet name="fastforward">
>     <x:outputText styleClass="paginatorLink" value="#{commonBundle.paginatorFastforward}"></x:outputText>
>   </f:facet>
>   <f:facet name="fastrewind">
>     <x:outputText styleClass="paginatorLink" value="#{commonBundle.paginatorFastrewind}"></x:outputText>
>   </f:facet>
> </x:dataScroller>
> sometimes dataScroller renders facets twice (but only links, not a table delimiters).
> I trace code and I found a method in class HtmlDataScrollerRenderer method renderFacet. The problem is the first line:
> UIComponent link = getLink(facesContext, scroller, facetComp, facetName);
> because in method getLink created link with not null child (facetComp).
> I replaced this line by:
> // create empty link, without children
> UIComponent link = getLink(facesContext, scroller, null, facetName);
> and component works good. I don't know what is a detailed specification of this component (now only first element from facet is rendered), so I don't create diff file.
