Performing action with a:commandButton - EntityManger closed

[bemar]

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

Ben
