I have a relationship similar to this one:
{code:java}
@Entity
public class EntityA {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@OneToOne(cascade = ALL)
@PrimaryKeyJoinColumn
private EntityB mydata;
{code}
and
{code:java}
@Entity
public class EntityB {
@Id
private Integer id;
@MapsId
@OneToOne
@JoinColumn(name = "id", updatable = false)
private EntityA a;
{code}
and while everything worked fine until hibernate 5.3, it does not work anymore with 5.4, with this error:
Caused by: org.hibernate.id.IdentifierGenerationException: null id generated for:class EntityB |
