    Problem with rich:tree and events

    Harald Höhn Newbie

      Hi,

       

      Im using richfaces 3.3.3 and i have problems with events in the rich:tree. I have a tree with 100k emelemts in it and each element have a <a4j:commandlink> which set states in a BackingBean to do other things with the selected element information. But sometimes the tree is hanging and i can't select another element or collapse an tree component....

       

      I see in the a4j log that the request to collapse the tree element will send correctly but the response will not have information about the elements to collapse. How can it be that the a4j request is send but the internal handling will not work. Can the ajax engine have a wrong state? If this state occur, alle events (other menu events to change to a new side also not work) are broken. But this "corrupt" state  always occur by selecting tree elements.

       

      Here are the information about my implementation:

       

      xhtml file:

       

      <a4j:form eventsQueue="WebQueue">

           <rich:tree id="group_tree_id" value="#{GroupTreeBean.treeNode}" stateAdvisor="#{TreeAdvisor}" var="item" switchType="ajax">

                <rich:treeNode iconLeaf="#{item.image}" icon="#{item.image}">

                     <a4j:commandLink reRender="Group_LD_id">

                          <h:outputText value="#{item}" escape="true">

                               <f:converter converterId="UrlConverter" />

                           </h:outputText>

                          <a4j:actionparam name="obid" value="#{item.obid}" assignTo="#{GroupDataBean.obid}"/>

                          <a4j:actionparam name="header" value="#{item.name}" assignTo="#{GroupDataBean.headerTitle}"/>

                     </a4j:commandLink>

                </rich:treeNode>

           </rich:tree>

      </a4j:form>

      Is therefore a workaround?

       

      Best regards
