Hello everyone,

I’ve got a problem with rich:tree and a4j:poll.


Code:

Tree File

<a4j:form style="display: inline;" id="arbre_form">
 <ratp:block styleClass="treeContainer">
 <h:panelGroup>
 <rich:tree
 rendered="true"
 ajaxSingle="true"
 switchType="ajax"
 value="#{Arbre.modelTree}"
 var="item"
 nodeFace="#{item.type}"
 id="arbre_materiel"
 binding="#{Arbre.tree}"
 iconCollapsed="${basePath}/styles/images/icones/collapsed.gif"
 iconExpanded="${basePath}/styles/images/icones/expanded.gif"
 reRender="arbre_form">
 <rich:treeNode

 </a4j:htmlCommandLink>
 </rich:treeNode>
 <rich:treeNode
 type="BASE_TREE_TYPE"
 rendered="true">
 <f:facet name="icon">

 </rich:treeNode>
 </rich:tree>
 </h:panelGroup>
 </ratp:block>

 <rich:contextMenu id="arbreContextMenu"
 onexpand="javascript:document.getElementById('html:body:arbre_form:valueToFiltreArbre').value=document.getElementById('hiddenFilter').value;
 document.getElementById('html:body:arbre_form:idTreeArbre').value=document.getElementById('hiddenIdTree').value;"
 oncollapse="javascript:contextMenuOpened = false;"
 submitMode="none"
 rendered="true"
 attached="false">
 <rich:menuItem id="arbreRichMenuItem">
 <h:panelGrid columns="3" id="arbrePanelridMenuItem">
 <h:outputText value="#{ArbreMessages['arbre.filtre']}: "/>
 <h:panelGroup>
 <h:inputText id="valueToFiltreArbre" size="6" value="#{Arbre.filtre}" />
 </h:panelGroup>
 <a4j:commandLink
 action="#{Arbre.filtre}"
 reRender="arbre_materiel">
 <h:graphicImage
 value="/styles/images/icones/valid.gif"
 style="cursor:pointer" />
 </a4j:commandLink>
 <h:inputHidden id="idTreeArbre" value="#{Arbre.idTree}" />
 </h:panelGrid>
 </rich:menuItem>
 </rich:contextMenu>


 <script>



 function updateFilter(newValue, idTreeValue){
 document.getElementById('hiddenFilter').value = newValue;
 document.getElementById('hiddenIdTree').value = idTreeValue;
 }


 </script>
 <input type="hidden" id="hiddenFilter" value=""/>
 <input type="hidden" id="hiddenIdTree" value=""/>
 </a4j:form>

Poll file:

<a4j:form>
<a4j:poll
 interval="1000"
 action="#{InformationBean.updateAction}"
 />
</a4j:form>

When the a4j:poll is called, the linked method to the value of the tree (#{Arbre.modelTree}) is called (the tree is not rerender).

In fact on each ajax request, this method is called whereas I don't rerender the tree.

Is there any problem in my code?
