I've put wrong version, correct code is without @Begin( join = true ) line:
| @Stateful
| @Name( "selectSeat" )
| @Conversational( ifNotBegunOutcome = "ERR" )
| @Interceptors( SeamInterceptor.class )
| public class SelectSeatAction implements Serializable, SelectSeat {
|
| private static final long serialVersionUID = 1L;
|
| @PersistenceContext( type = PersistenceContextType.EXTENDED )
| private EntityManager cinemaDatabase;
|
| private Set<Seat> selectedSeats = new HashSet<Seat>( );
|
| @Out( scope = ScopeType.CONVERSATION )
| Seat seat;
|
|
| public String select( String place ) {
|
| this.seat = (Seat) cinemaDatabase.createQuery( "from Seat where row
|| ',' || number = :place" ).setParameter(
| "place", place ).getSingleResult( );
|
| selectedSeats.add( seat );
|
| return seat.getState( ).toString( );
| }
|
| @Destroy
| @Remove
| public void destroy( ) {
|
| }
| }
|
