Hi!

I've got a problem with DetachedCriteria and In-List.
Please have a look at my code:


Code:
Criteria crit =
   s.createCriteria(ServiceAssignment.class, "sa")
   .createAlias("service", "s");

DetachedCriteria dc = DetachedCriteria
   .forClass(ResourceReservation.class, "res")
   .setFetchMode("res.pk.resource", FetchMode.JOIN)
   .createAlias("res.pk.resource.employee", "resEmp")
   .add( Restrictions.eq("resEmp.id", searchData.getTechnicianId()))
   .setProjection(Property.forName("res.pk.refNo1"));
   
crit.add(Property.forName("sa.id").in(dc));



The related Entitys are defined as follows:

Code:

@Entity
@Table(name="SERVICE")
public class Service extends DefaultBusinessData implements Serializable {

   private static final long serialVersionUID = 8319881504472814377L;
   
   @Id
   @Column(name="SERVICENR")
   private Long id;
}

@Entity
@Table(name="SRVEINSATZ")
public class ServiceAssignment  implements Serializable {
   
   private static final long serialVersionUID = -4423630394669230016L;

   @Id
   @Column(name="EINSATZNR")
   private Long id;
   
   @ManyToOne(fetch=FetchType.LAZY)
   @JoinColumn(name="LFDSERVICENR")
   private Service service;
}

@Entity
@Table(name="RESBELEGUNG")
public class ResourceReservation implements Serializable {

   private static final long serialVersionUID = -7434828090715354721L;

   @Id
   private ResourceReservationPK pk;
   
}

@Embeddable
public class ResourceReservationPK implements Serializable {

   private static final long serialVersionUID = -6822968368044282709L;

   @ManyToOne(fetch=FetchType.LAZY)
   @JoinColumn(name="LFDRESNR")
   private Resource resource;
   
   @Column(name="AUFKOPFNR")
   private Long refNo1;
   
}

@Entity
@Table(name="RESSOURCE")
public class Resource implements Serializable {

   private static final long serialVersionUID = -4063075607856411271L;

   @Id
   @Column(name="LFDNR")
   private Long id;
   
   @ManyToOne(fetch=FetchType.LAZY)
   @JoinColumn(name="LFDMITARBNR")
   private Employee employee;
}

@Entity
@Table( name = "MITARBEITER" )
public class Employee extends DefaultBusinessData implements Serializable {

   private static final long serialVersionUID = -5362260719432683301L;

   @Id
   @Column( name = "mitarbnr" )
   private Long id;
}



When executing, I get the following error:
