Hello,

I used the clickable list example described in chapter 1.3 in the reference guide to \
create my own list page, but I have some:

javax.faces.el.PropertyNotFoundException

when I try to display the datatable

The weird thing is that the same Object is in the DataModel and in the "var" of my \
datatable:


  | certif	com.fitnetapplication.certifications.entity.CertificationList@1faa588
  | certificationList	com.fitnetapplication.certifications.entity.CertificationList@1faa588
  | 

(This comes from the debug page)

Here is my bean code :


  | @Stateless
  | @Name("myCertifications")
  | public class MyCertificationsBean implements MyCertifications {
  | 	
  |     @Logger private Log log;
  | 	
  |     @In FacesMessages facesMessages;
  |     
  |     @DataModel
  |     private List<Certification> certificationList;
  |     
  |     @DataModelSelection
  |     @Out(required=false)
  |     private Certification certification;
  |     
  |     @In(value="entityManager")
  |     private EntityManager em;
  |     
  |     @In(value="loggedCollaborateur", required=false, create=true)
  |     Collaborateur loggedCollaborateur;
  |     
  |     @Factory("certificationList")
  |     public void findMessages()
  |     {    	    	
  | 
  | (...) blablabla, I'm fetching all my list (...)
  |     	
  |     } 
  | 

My page :


  |     <h:dataTable id="certificationList" 
  |                 var="certif"
  |               value="#{certificationList}" >
  |         <h:column>
  |             <f:facet name="header">
  |                 <s:link styleClass="columnHeader"
  |                              value="certificationId \
#{certificationList.order=='certificationId asc' ? messages.down : ( \
certificationList.order=='certificationId desc' ? messages.up : '' )}">  |            \
<f:param name="order" value="#{certificationList.order=='certificationId asc' ? \
'certificationId desc' : 'certificationId asc'}"/>  |                 </s:link>
  |             </f:facet>
  |             <h:outputText value="#{certif.certificationId}"></h:outputText>
  |         </h:column>
  | 
  | etc (...)
  | 

I also tried with a rich:datatable but it didn't change.

What am I doing wring here ?
Why isn't there any "Certification" objects in my "certif" var in the jsf page ?
