We have a query:

Code:
select f from equipment_Equipment f where f.type=com.nokia.nspos.model.domain.equipment.types.EquipmentType.port


that is failing with:

Code:

Hi,
can you give us more details about the entity and which datastore you are using?

Sorry for the late reply, I've only seen this today.

Thanks,
Davide

Right, this is with Neo4j. Not sure what details you're looking for, but here's a basic outline of the classes. I've omitted other fields, and all getters/setters.

Code:
@Entity(name = "equipment_Equipment")
@Table(name = "EQUIPMENT_EQUIPMENT")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@Access(AccessType.FIELD)
public class Equipment extends com.nokia.nspos.model.domain.equipment.entities.AbstractEquipment   {
  ...
}

@Entity(name = "equipment_AbstractEquipment")
@Table(name = "EQUIPMENT_ABSTRACTEQUIPMENT")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@Access(AccessType.FIELD)
public abstract class AbstractEquipment extends com.nokia.nspos.model.domain.core.entities.SourcedManagedObject  implements com.nokia.nspos.model.domain.common.entities.Stateful, com.nokia.nspos.model.domain.common.entities.ObjectDetailsHolder
{
  ...
    @Basic(optional = false)
    private com.nokia.nspos.model.domain.equipment.types.EquipmentType type;
  ...
}

public enum EquipmentType implements IManagedEnum {
    /**
     An unexpected equipment type not matching any of the other enum values
     */
    unknown(0, "unknown"),

  ...

   /**
     */
    rack(8, "rack"),
    /**
     */
    port(9, "port"),
    ;
}

I think you are missing the annotation
Code:
@Enumerated
.


It should be:
Code:
import javax.persistence.Enumerated;

...
   @Basic(optional = false)
   @Enumerated   
   private com.nokia.nspos.model.domain.equipment.types.EquipmentType type;
...

I finally got a chance to test this.

Not a big surprise, but that doesn't fix the error. @Enumerated is documented as optional.
