JPA/Hibernate shared primary key and @OneToOne mapping


JPA/Hibernate shared primary key and @OneToOne mapping



Is it possible,when using @OneToOne mapping and shared primary key to insert child object,while updating Parent object?


public class Project{
@Id
@SequenceGenerator(name = "projectsIdSeq", sequenceName = "PROJECTS_ID_SEQ", allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "projectsIdSeq")
private Long id;

@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "ID", referencedColumnName = "PROJECT_ID")
@PrimaryKeyJoinColumn
private PlanningStageInfo planningStageInfo;
}


public class PlanningStageInfo{
@Id
@Column(name = "PROJECT_ID")
private Long projectId;

@NotAudited
@JsonIgnore
@MapsId
@OneToOne(mappedBy = "planningStageInfo")
private Project project;
}



When I'm trying to update Project without PlanningStageInfo I'm getting eroor


Caused by: org.hibernate.id.IdentifierGenerationException: attempted to assign id from null one-to-one property [ge.msda.buildtbilisi.model.PlanningStageInfo.project]





I've tried,but I'm getting exception
