ISSUE Retrieve ViewRowImpl attributes using ExpressionLanguage

Question

Hello,
In my page JSPX I use a popupFetchListener to store my ROW in pageFlowScope, when I try to retrieve one of attributes I encountered this error :
<font color="red">
PropertyNotFoundException The class fr.annuaire.model.views.annuaire.EdpViewRowImpl does not have the property NbUti.
</font>
the error comes from the line disabled="#{pageFlowScope.currentEdpRow.NbUti > 0}"
The attribute exists in the ViewRowImpl, see code below
How can i access to attributes via ExpressionLanguage ?
IN JSPX :
<af:table value="#{bindings.EdpViewSearch.collectionModel}" var="row"
     id="tabEdp"
     rowSelection="none"
     contentDelivery="immediate"
     clientComponent="true"
     contextMenuSelect="true">
    <f<colon>facet name="contextMenu">
      <af:popup id="popupEdp" contentDelivery="lazyUncached" popupFetchListener="#{backingBeanScope.backing_entiteUtilisateurTab.popupMenuEdpFetchListener}">
     <af:menu id="m6">
       <af:commandMenuItem id="cmiSupprimerSingleEdpCM"
                     text="Supprimer"
                     disabled="#{pageFlowScope.CurrentEdpRow.NbUti > 0}"
                     actionListener="#{backingBeanScope.backing_entiteUtilisateurTab.actionOpenPopSupEdp}"/>
IN BACKING BEAN : backing_entiteUtilisateurTab
public void popupMenuEdpFetchListener(PopupFetchEvent fetchEvent) {
  JUCtrlHierNodeBinding nodeRoot = (JUCtrlHierNodeBinding)this.getTabEdp().getRowData();
  Map<String, Object> mpPageFlowScope = AdfFacesContext.getCurrentInstance().getPageFlowScope();
  SgtiEdpViewRowImpl row = (SgtiEdpViewRowImpl)nodeRoot.getRow();  
  mpPageFlowScope.put("CurrentEdpRow", row);
IN MODEL :
public class EdpViewRowImpl extends ViewRowImpl {
    public enum AttributesEnum {
        NbUti {
            public Object get(EdpViewRowImpl obj) {
                return obj.getNbUti();
            public void put(EdpViewRowImpl obj, Object value) {
                obj.setNbUti((BigDecimal)value);
    public static final int NBUTI = AttributesEnum.NbUti.index();
    public BigDecimal getNbUti() {
        return (BigDecimal)getAttributeInternal(NBUTI);
    public void setNbUti(BigDecimal value) {
        setAttributeInternal(NBUTI, value);
}Thank you

Although it's probably not the cause of your problem, you should not be sticking a ViewRowImpl into page flow scope, the reason being is that ViewRowImpl is not Serializable, and page flow scope is a map in session scope. Does it work if you put the attribute into page flow scope directly?
