Try

@ReturnInsert(returnOnly=true)

That should work on PostgreSQL, too.

 

Just what I need, thanks!

 

Hm, I get a runtime-exception when using this:

 

Exception [EclipseLink-189] (Eclipse Persistence Services - 2.5.1.v20130814-ad1d746): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: ReturningPolicy contains mapped field, [id] which requires type.
Descriptor: RelationalDescriptor(no.officenet.origo.core.domain.model.person.Person --> [DatabaseTable(onp_crm_entity), DatabaseTable(onp_crm_person)])

 

 

My mapping in @Entity Person is:

 

@Column(name = "id", nullable = false, unique = true, updatable = false, insertable = false)
@ReturnInsert(returnOnly=true)
var personId: java.lang.Long = null

 

This inherits from an AbstractEntityObject which defines @Id:

 

@Entity
@Table(name = "onp_crm_entity")
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "type", discriminatorType = DiscriminatorType.STRING)
@SequenceGenerator(name = "AbstractEntityObjectSEQ_STORE", sequenceName = "onp_crm_entity_id_seq", allocationSize = 1)
abstract class AbstractEntityObject(_contentType: ContentType) extends AbstractDomainObject {
//...
//...
@Id
@Column(name = "entity_id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "AbstractEntityObjectSEQ_STORE")
var id: java.lang.Long = null

Any hints on what's wrong?

 

without @ReturnInsert annotation the app works but the property isn't populated on persist.
