[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5091) Unidirectional One-To-Many relationship with foreign key mapping doesn't work

Unidirectional One-To-Many relationship with foreign key mapping doesn't work ----------------------------------------------------------------------------- Key: HHH-5091 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5091 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.0-Final Reporter: Juergen Zimmermann I've the following 2 tables (in PostgreSQL) in a one-to-many relationship with foreign key mapping: CREATE TABLE bestellung( b_id BIGSERIAL NOT NULL PRIMARY KEY, version INTEGER DEFAULT 0, kunde_fk BIGINT NOT NULL REFERENCES kunde(k_id) ); CREATE TABLE bestellposition( bp_id BIGSERIAL NOT NULL PRIMARY KEY, version INTEGER DEFAULT 0, artikel_fk BIGINT NOT NULL REFERENCES artikel(a_id), anzahl SMALLINT NOT NULL, bestellung_fk BIGINT NOT NULL REFERENCES bestellung(b_id) ); Now the 2 JPA entity classes: // owner class @Entity @Table(name="bestellung") public class Bestellung implements java.io.Serializable { @Id @GeneratedValue(generator="bestellung_sequence_name") @SequenceGenerator(name="bestellung_sequence_name", sequenceName="bestellung_b_id_seq", allocationSize=1) @Column(name="b_id", nullable=false) private Long id = null; @Version private int version = 0; // bidirectional @ManyToOne(optional=false) @JoinColumn(name="kunde_fk") @NotNull(message="{bestellverwaltung.bestellung.kunde.notNull}") private Kunde kunde; // unidirectional and cascading persist @OneToMany(fetch=EAGER, cascade={PERSIST, REMOVE}, orphanRemoval=true) @JoinColumn(name="bestellung_fk") @OrderBy("id ASC") @NotEmpty(message="{bestellverwaltung.bestellung.bestellpositionen.notEmpty}") private List<Bestellposition> bestellpositionen; } // dependant class @Entity @Table(name="bestellposition") public class Bestellposition implements java.io.Serializable { @Id @GeneratedValue(generator="bestellposition_sequence_name") @SequenceGenerator(name="bestellposition_sequence_name", sequenceName="bestellposition_bp_id_seq", allocationSize=1) @Column(name="bp_id", nullable=false) private Long id = null; @Version private int version = 0; @Column(nullable=false) @Min(value=ANZAHL_MIN, message="{bestellverwaltung.bestellposition.anzahl.min}") private short anzahl = 1; @ManyToOne(optional=false) @JoinColumn(name="artikel_fk") @NotNull(message="{bestellverwaltung.bestellposition.artikel.notNull}") private Artikel artikel; } Inside the owner class the dependent class is declared with cascade=PERSIST (see above). When I try to create a persistent entity of class Bestellung (owner class) then the generated SQL statement is wrong because the foreign key ("bestellung_fk") for the owner record is missing. insert into bestellposition(anzahl, artikel_fk, version, bp_id) values(?, ?, ?, ?)
