    Datamodel: casting exception on @Destroy - Submit bug?

      Is there a bug that should be reported for the following?:


      Getting the following error for a datamodel when it is used to display an h:dataTable. The dataTable is displayed fine. However, in the log, I receive:


      15:04:42,312 WARN  [Component] Exception calling component @Destroy method: deliveryDeadlineOptionList
javax.ejb.EJBException: java.lang.ClassCastException: java.util.ArrayList cannot be cast to javax.faces.model.DataModel
at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:77)
...



      The bean for this is used for the following two purposes:


      1. Value of an s:selectItems


      2. Value of an h:dataTable (i.e., as mentioned above)


      The bean:


      @Stateful
@Scope(CONVERSATION)
@Name("deliveryDeadlineOptionList")
@TransactionAttribute(REQUIRES_NEW)
public class DeliveryDeadlineOptionListAction implements DeliveryDeadlineOptionList, Serializable
{
@PersistenceContext(type=PersistenceContextType.EXTENDED)
@In(create=true)
private EntityManager entityManager;

@DataModel
private List<DeliveryDeadlineOption> deliveryDeadlineOptionsList;

@DataModelSelection
private DeliveryDeadlineOption deliveryDeadlineOption;

@Create
public void create() {getDeliveryDeadlineOptionsList();}

@Factory
public List<DeliveryDeadlineOption> getDeliveryDeadlineOptionsList(){
return (List<DeliveryDeadlineOption>) entityManager.createQuery("select c from DeliveryDeadlineOption c")
.getResultList();
}

public DeliveryDeadlineOption getDeliveryDeadlineOption(){return deliveryDeadlineOption;}

@Destroy
@Remove
public void destroy() {}
}



      Relevant portions of the bean where deliveryDeadlineOptionList is used for the s:selectItems functionality:


      @Stateful
@Name("quoteCalculate")
@Scope(ScopeType.CONVERSATION)
public class QuoteCalculatingAction implements QuoteCalculating
{
@PersistenceContext(type=PersistenceContextType.EXTENDED)
@In(create=true)
private EntityManager entityManager;

...

@In(value="deliveryDeadlineOptionsList", create=true)
private List<DeliveryDeadlineOption> deliveryDeadlineOptions;

@DataModel
private List<DeliveryDeadlineOption> selectedDeliveryDeadlineOptions;

...

(Standard getters and setters for above)

public void selectedDeliveryDeadlineOptionsChange(ValueChangeEvent valueChangeEvent) {
setSelectedDeliveryDeadlineOptions((List<DeliveryDeadlineOption>) valueChangeEvent.getNewValue());
...
}
...
}
