Hi list,
I am using OpenJPA 2.0, Posgresql and JDBC4
and the following entity (well - its Scala ;-) @BeanProperty
translates to a private property and a setter- and getter-method):
@Entity
@Table(name = "org_struct")
@IdClass(classOf[OrganisationStructureId])
@SequenceGenerator(name = "org_struct_index_seq", sequenceName =
"org_struct_index_sequence", allocationSize = 1)
class OrganisationStructure extends MIPEntity {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator =
"org_struct_index_seq")
@Column(name = "org_struct_ix", nullable = false, length = 20)
@BeanProperty
protected var ix: BigInteger = _
@Id
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "org_struct_root_org_id", nullable = false,
updatable = false)
@BeanProperty
protected var orgStructRootOrg: Organisation = _
}
/**
* ID Class
*/
class OrganisationStructureId {
@BeanProperty
var orgStructRootOrg: BigInteger = _
@BeanProperty
var ix: BigInteger = _
. . .
}
Doing persist I get the following exception:
org.apache.openjpa.persistence.PersistenceException: Can not set

I think OpenJPA tries to put an Organisation into the BigInt field. Any advice?
