      Hi,

      I've got a table where only one component should be reRendered (valD)

      Tried to do something, but without success...

      <a4j:poll action="#{bean.updateStats2}" immediate="true" interval="5000" reRender="ble"/>
 <h:panelGrid>
 <a4j:repeat binding="#{bean.gamesRepeat}" id="gamesRow" value="#{bean.gamesIt}" var="games_it">
 <h:panelGrid columns="2">
 <h:panelGrid>
 <h:outputText id="valA" value="#{games_it.valA}"/>
 <h:outputText id="valB" value="#{games_it.valB}"/>
 </h:panelGrid>
 <h:panelGrid>
 <h:outputText id="valC" value="#{games_it.valC}"/>
 <a4j:outputPanel id="ble">
 <h:outputText binding="#{bean.valDText}" id="valDText" value="#{games_it.valD}"/>
 </a4j:outputPanel>
 </h:panelGrid>
 </h:panelGrid>
 </a4j:repeat>
 </h:panelGrid>


      Can anyone help? Any hints how it should be done?

            Sorry, I don't get it. I've tried:

            <a4j:log/>
 <a4j:poll action="#{bean.updateStats2}" immediate="true" interval="5000" reRender="gamesRow"/>
 <h:panelGrid>
 <a4j:repeat binding="#{bean.gamesRepeat}" id="gamesRow" value="#{bean.gamesIt}" var="games_it" ajaxKeys="#{bean.ajaxedRowsSet}">
 <h:panelGrid columns="2">
 <h:panelGrid>
 <h:outputText id="valA" value="#{games_it.valA}"/>
 <h:outputText id="valB" value="#{games_it.valB}"/>
 </h:panelGrid>
 <h:panelGrid>
 <h:outputText id="valC" value="#{games_it.valC}"/>
 <h:outputText binding="#{bean.valDText}" id="valDText" value="#{games_it.valD}"/>
 </h:panelGrid>
 </h:panelGrid>
 </a4j:repeat>
 </h:panelGrid>




            public List ajaxedRowsSet() {
 ListDataModel model = (ListDataModel)gamesRepeat.getValue();
 TempModel row = null;
 int rows = model.getRowCount();
 List list = new ArrayList();
 for(int i=0;i<rows;i++) {
 model.setRowIndex(i);
 row = (TempModel)model.getRowData();
 System.out.println("id: " + valDText.getId());
 list.add(valDText.getId());
 }
 return list;
 }


            buit nothing happens. And Log4j shows this error

            error[10:53:38,250]: New node for ID main:gamesRow is not present in response

            Looks like method for getting ids is not even invoked.
