Hi,
I have a One-To-Many relation with the Many-entity having an composite id with AttributeOverrides. This works fine with 6.2.0-CR3 ( and 5), but starts failing with CR4.
{noformat}java.lang.ClassCastException: class org.hibernate.mapping.BasicValue cannot be cast to class org.hibernate.mapping.ToOne (org.hibernate.mapping.BasicValue and org.hibernate.mapping.ToOne are in unnamed module of loader 'app'){noformat}
I attached a test case.
[^hibernate-orm-6.zip]
{noformat}@Entity
public class Contract implements Serializable {
private static final long serialVersionUID = 1L;
@Id
private Integer contractId;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "id.contractId")
@OrderBy(value = "id.positionNumber")
private List<Contractposition> contractpositions = new ArrayList<>();{noformat}
{noformat}@Entity
public class Contractposition implements Serializable {
private static final long serialVersionUID = 1L;
@EmbeddedId
@AttributeOverrides(
{
@AttributeOverride(name = "contractId", column = @Column(name = "VERTRAG_ID", nullable = false)),
@AttributeOverride(name = "positionNumber", column = @Column(name = "POSITIONSNUMMER", nullable = false))})
private ContractpositionId id;{noformat}
{noformat}@Embeddable
public class ContractpositionId implements Serializable {
private static final long serialVersionUID = 1L;
@Column(name = "VERTRAG_ID", nullable = false)
private Integer contractId;
@Column(name = "POSITIONSNUMMER", nullable = false)
private int positionNumber;{noformat}
Debugging shows:
