reRender HtmlPanelGroup children

[svkap]

Hello.

I have some problems with rerendering of HtmlPanelGroup. I have tried using HtmlAjaxCommandLink + rerender, HtmlAjaxSupport + onclick + rerender but nothing works. I assume that just the component cannot be found to be rerendered but I do not know why. Here is my jsf page:

My backing bean is generating the content. In short I have 3 HtmlPanelGroups generated inside (as children) and each of them has several children. When I click on the command link panelRoot.getChildren().clear(); is called, all children are generated again with different values and finally the new HtmlPanelGroups are added to panelRoot as children. I can see that in the backing bean the children are generated as expected but the panelRoot is not rerendered. Here is part of my code:

        HtmlAjaxCommandLink linkNextPage = new HtmlAjaxCommandLink();
        linkNextPage.setId("linkNextPage_id_" + uniqueId);
        linkNextPage.setValue("Next");
        linkNextPage.setDisabled(!isNextPageAvailable());
        linkNextPage.setReRender(panelRoot.getId());
        linkNextPage.addActionListener(nextPageListener);

//        HtmlAjaxSupport asNextPage = new HtmlAjaxSupport();
//        asNextPage.setId("ajax_nextPage_id_" + uniqueId);
//        asNextPage.setEvent("onclick");
//        asNextPage.setReRender("panelRoot_id");
//
//        linkNextPage.getChildren().add(asNextPage);

Thank you.

Hi Svetoslav,

Try assigning explicit IDs to panel.

Hi Nick.

I am actually using explicit id for the panelRoot (set in the JSF page). panelRoot.getId() returns the correct ID. I have tried using the id ("panelRoot_id") as string instead of panelRoot.getId() but the result was the same.

try to enclose panelGroups inside the <a4j:outputPanel ajaxRendered="true">

Hi.

I tired that but unfortunately it did not work . Here is a part of my jsf page:

         <h:form id="form_id" >
             <a4j:outputPanel ajaxRendered="true">
                 <h:panelGroup layout="block" id="panelRoot_id"
                     style="width:580px;" binding="#{bean.panelRoot}">
                 </h:panelGroup>
             </a4j:outputPanel>
         </h:form>

Hi.

This was mistiriously fixed. I have only changed panel ID and panel bindnig property and it is working fine now.

<h:panelGroup layout="block" id="panelRoot_id_Test" style="width:580px;" 
                binding="#{bean.panelRootTest}" />

I do not know why it is working now but I am happy .
