    RichFaces, Regions and Jboss EL - bad mix?

    Magnus Sandberg Novice

      I don't know if this is RichFaces, Seam or EL issue or if this is just impossible (original problem JBoss  ELExpression Evaluates To Null)


      This does not work, id is always null is action method:


      <rich:dataTable   
        value="#{admin.infoEditList.items}" 
        var="info">
          <h:column>
              <a4j:region>
                  <a4j:commandLink 
                    action="#{admin.infoEditList.selectItem(info.id)}" />                            
              </a4j:region>
          </h:column>
      </rich:dataTable>



      removing the region and the correct id is used in the action:


      <rich:dataTable   
        value="#{admin.infoEditList.items}" 
        var="info">
          <h:column>
              <a4j:commandLink 
                    action="#{admin.infoEditList.selectItem(info.id)}" />                            
          </h:column>
      </rich:dataTable>



      placing the region outside the table works as well:


      <a4j:region>
        <rich:dataTable   
         value="#{admin.infoEditList.items}" 
         var="info">
           <h:column>
               <a4j:commandLink 
                     action="#{admin.infoEditList.selectItem(info.id)}" />                            
           </h:column>
       </rich:dataTable>
      </a4j:region>



      replacing the a4j:commandLink with h:commandLink or s:link makes no differance - the EL is not evaluated at render time.
