UIComponent problems with rendered and actionListener

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hi,

I'm currently modifying the browse jsp.

I want to list all nodes (content and folder) in one single UIRichList.

For this purpose i set some rendered tag in order to distinguish the rendering of folders, and the rendering of contents.

NB: I added my own NodePropertyResolver in order to get a new
nodeType value to test wether i have a node which is subclass of a folder (cm:folder) or not (cm:content).

<%– if folder, use this actionLink –%>
<a:actionLink id="col1-act2" value="#{r.name}" actionListener="#{BrowseBean.clickSpace}" rendered="#{r.nodeType=='folder'}">
   <f:param name="id" value="#{r.id}" />
</a:actionLink>
                              
<%– if not folder, use this actionLink –%>
<a:actionLink id="col9-act2" value="#{r.name}" href="#{r.url}" target="new" rendered="#{r.nodeType == 'content'}" />
<r:lockIcon id="col9-lock" value="#{r.nodeRef}"   align="absmiddle" rendered="#{r.nodeType == 'content'}"/>

My problem is that once I set a rendered tag, the actionListener seems to not working. (I click, and nothing's happen…)

Can you help me on this topic.

Maybe I can provide exactly what I did.
In fact, I set up a new Backing bean, which uses the browsebean to get all nodes.

I'm creating a new list upon the BrowseBean.getNodes() and BrowseBean.getContent() functions.

for each node I get, I add a NodePropertyResolver which check if node is a subclass of folder, or content.

Here's the code…

package xxx.portal.web.bean;

import java.util.ArrayList;
import java.util.List;

import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;

import org.alfresco.model.ContentModel;

import org.alfresco.service.cmr.dictionary.DictionaryService;
import org.alfresco.service.cmr.repository.NodeRef;
import org.alfresco.web.app.context.IContextListener;
import org.alfresco.web.app.context.UIContextService;
import org.alfresco.web.bean.BrowseBean;
import org.alfresco.web.bean.repository.Node;
import org.alfresco.web.bean.repository.NodePropertyResolver;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

Here's the faces-config.

      <description>Back bean for external user browsing</description>
      <managed-bean-name>LightBrowseBean</managed-bean-name>
      <managed-bean-class>xxx.portal.web.bean.LightBrowseBean</managed-bean-class>

Hope it will help.
