    Performing action with a:commandButton - EntityManger closed

    Benjamin Mark Newbie

      Hello,


      I wan't to perform a action with my entity bean via a:commandButton but when the action calls the method in the bean the error


      Caused by: java.lang.IllegalStateException: EntityManager is closed



      is thrown. I'm using a standard seam-gen bean.


      The error


      Caused by: javax.el.ELException: /IncidentSearch.xhtml @124,48 value="#{incidentSearchList.calcResult}": Error reading 'calcResult' on type ch.bemar.creditfriend.action.IncidentSearchList_$$_javassist_seam_5

      My xhmtl file


      <a:status id="globalStatus" 
                          onstart="Richfaces.showModalPanel('loading', {width:'70x', height:'70px'});"
                          onstop="Richfaces.hideModalPanel('loading');" />
      
      <rich:simpleTogglePanel label="#{messages.text_foundincidents}"
                          switchType="ajax">
      
                          <s:decorate id="foundPersonField" template="layout/edit.xhtml">
                               <ui:define name="label">Person gefunden</ui:define>
                               <h:outputText id="foundPerson" size="45"
                                    value="#{incidentSearchList.calcResult}">                              
                               </h:outputText>
                          </s:decorate>
                     </rich:simpleTogglePanel>
      
      
      <a:commandButton id="infotext"
                          value="a:#{messages.text_search}"
                          disabled="#{incidentSearchList.incidentSearch.validInput==false}"
                          status="globalStatus" reRender="foundPersonField"/> 




      The bean




      /**
           * Get the list of results this query returns
           * 
           * Any changed restriction values will be applied
           */
          @Transactional
          public Integer getCalcResult()
          {
              System.out.println(incidentSearch);
              List<Incident> incidentList = super.getResultList();
              this.foundPersons = incidentList.size();
              return this.foundPersons;
          }



      What could be the problem?


      Thx for your help
