I try to do the pagenation in rich:dataTable with the rich:datascroller, but when I click the datascroll, there is no response.

What else config should I add in the datascroll,

here's my code:

Thanks!

<h:form>
    <rich:dataTable id="metadataList"
                var="_metadata"
              value="#{metadataList.resultList}"
           rendered="#{not empty metadataList.resultList}">
        <h:column>
            <f:facet name="header">
                <ui:include src="layout/sort.xhtml">
                    <ui:param name="entityList" value="#{metadataList}"/>
                    <ui:param name="propertyLabel" value="Activity id"/>
                    <ui:param name="propertyPath" value="metadata.activityId"/>
                </ui:include>
            </f:facet>
            <h:outputText value="#{_metadata.activityId}"/>
        </h:column>       
        <f:facet name="footer">
             <rich:datascroller  for="metadataList" maxPages="3"/>
       </f:facet>
       
       </rich:dataTable>
</h:form>
