Hello,

I'm using ICEfaces 1.5.3. By and large, it's working very well for our demanding project.

Ran into the following issue when using the tree component. We're displaying an organization hierarchy using a tree component, with icons displayed conditionally.

Code:

            <ice:panelGrid width="100%" cellpadding="0" cellspacing="0" columns="2">
                 <ice:graphicImage value="/images/common/dot.gif"/>
                 <ice:tree id="orgTree"
                           value="#{treeBean.model}"
                           var="node"
                           hideRootNode="false"
                           hideNavigation="false"
                           imageDir="#{facesContext.externalContext.request.contextPath}/images/common/tree/">
                     <ice:treeNode>
                         <f:facet name="icon">
                             <ice:panelGroup style="display: inline">
                                 [b]<ice:commandLink id="_#{node.userObject.id}" actionListener="#{controller.nodeSelected}">[/b]
                                     <ice:graphicImage
                                             value="/images/common/org.jpg"/>
                                 </ice:commandLink>
                                 <ice:outputLink value="#{facesContext.externalContext.request.contextPath}/com/ketera/web/organization/create/create-edit-org.iface"
                                         rendered="#{(displayEditBtn eq 'Y')>
                                     <ice:graphicImage value="/images/common/edit.gif" title="Edit Org"/>
                                     <f:param name="id" value="#{node.userObject.id}"/>
                                 </ice:outputLink>
                                 <ice:outputLink value="#{facesContext.externalContext.request.contextPath}/com/ketera/web/organization/view/view-org-profile.iface"
                                         rendered="#{(displayViewBtn eq 'Y')>
                                     <ice:graphicImage value="/images/common/view.gif" title="View Org"/>
                                     <f:param name="id" value="#{node.userObject.id}"/>
                                 </ice:outputLink>
                             </ice:panelGroup>
                         </f:facet>
                         <f:facet name="content">
                             <ice:panelGroup style="display: inline">
                                 [b]<ice:commandLink id="_#{node.userObject.id}" actionListener="#{controller.nodeSelected}">
 [/b]                                    <ice:outputText value="#{node.userObject.name}" style="font-style: italic"/>
                                 </ice:commandLink>
                             </ice:panelGroup>
                         </f:facet>
                     </ice:treeNode>
                 </ice:tree>
             </ice:panelGrid>

ActionListener:
Code:

   public void nodeSelected(javax.faces.event.ActionEvent actionEvent)
   {
       logger.debug("parentOrgSelected: selected org id [" + actionEvent.getComponent().getId() + "]");
   }

The id value is logged as "_". That is, the value of Code:

#{node.userObject.id}

is either not being resolved, or it's incorrectly initialized.

Any idea why this is happening?

In some other pages, I'm using a similar commandLink -> actionListener without any issues. However, in that case, the command link is inside a panelGrid, not a tree component.

Thanks in advance.

Hi Spartacus,

The "id" can be generated dynamically only if facelets being used, without facelets the id attribute can not have a value binding. So just wondering if you are using facelets?

Thanks,

Instead of passing the ID via the component, you could pass it via f:param

Code:

 <ice:commandLink 
                                 actionListener="#{tree.nodeClicked}">
                              <f:param name="clickedId"
                             value="#{item.userObject.id}"/>
                             <ice:outputText
                                     value="#{item.userObject.id}"/>
                         </ice:commandLink>

Hi,

please could you tell me how to get parameter "clickedId" into the backingbean?

thanks

OK I found. But We can't pass objects? just String with f:param :(

FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("clickedId");

I'm trying to use a commandLink with actionListener arround my graphicImage in the treeNode.

But it never goes to the actionListener.

Code:

 In the xhtml:
 <ice:tree var="treeNode" hideRootNode="false" hideNavigation="false"
      value="#{bean.tree.model}" 
     imageDir="./xmlhttp/css/xp/css-images/" >
   <ice:treeNode>
     <f:facet name="icon">
       <ice:panelGroup style="display: inline">
         <ice:commandLink actionListener="#{bean.klikTest}">
           <h:graphicImage value="#{treeNode.userObject.icon}"/>
 	</ice:commandLink>
       </ice:panelGroup>
     </f:facet>
     <f:facet name="content">
       <ice:panelGroup style="display: inline" >
         <ice:commandLink 
             actionListener="#{treeNode.userObject.nodeClicked}" 
             value="#{treeNode.userObject.text}"
 	    title="#{treeNode.userObject.text}"
 	    action=".../>
       </ice:panelGroup>
     </f:facet>
   </ice:treeNode>
 </ice:tree>
 
 In the bean:
 public void klikTest(ActionEvent e) {
   System.out.println("!!!!! klik");
 }

I'm using version 1.8.1.

What am I doing wrong?

Thx,
Kevin
