Hello

I search since 4 days for the following problems and I am really desperate :-(

Problem1:

I would like to embed the attributes "datum" and "datumszusatz" in the class "HFPersonImpl" from the class "ErweitertesDatumImpl". Hibernate override the Attribut "datum" but not "datumszusatz" (look at Example1).
If I don't use the Relationship, Hibernate generates the attribute "datumszusatz" (Example2). Why? Where is the mistake? Ist it a Hibernate bug?


EXAMPLE1
HFPersonImpl
...
@Embedded
@Target(de.ard.sad.trinidad.bo.ndb.impl.hibernate.basis.ErweitertesDatumImpl.class)
@AttributeOverrides( {
@AttributeOverride(name = "datum", column = @Column(name = "G_DAT_DATUM", columnDefinition = "VARCHAR2(20)")),
@AttributeOverride(name = "datumszusatz", column = @Column(name = "G_DAT_FK_DAT_ZUS_WERT", columnDefinition = "NUMBER(19)")) })
private ErweitertesDatum geburtsdatum;

@Embedded
@Target(de.ard.sad.trinidad.bo.ndb.impl.hibernate.basis.ErweitertesDatumImpl.class)
@AttributeOverrides( {
@AttributeOverride(name = "datum", column = @Column(name = "T_DAT_DATUM", columnDefinition = "VARCHAR2(20)")),
@AttributeOverride(name = "datumszusatz", column = @Column(name = "T_DAT_FK_DAT_ZUS_WERT", columnDefinition = "NUMBER(19)")) })
private ErweitertesDatum todesdatum;
...

ErweitertesDatumImpl
@Entity
@Table(name = "ERWEITERTES_DATUM")
@Embeddable
public class ErweitertesDatumImpl implements ErweitertesDatum, Serializable {
...
@Column(name = "DATUM", columnDefinition = "VARCHAR2(20)")
@Target(de.ard.sad.trinidad.bo.hibernate.dataTypes.DateIntervalUserType.class)
private DateInterval datum;

@ManyToOne(targetEntity = de.ard.sad.trinidad.bo.ndb.impl.hibernate.wert.DatumzusatzImpl.class)
@JoinColumn(name = "FK_DAT_ZUS_WERT", columnDefinition = "NUMBER(19)")
private Datumzusatz datumszusatz;
...

Result:

[hibernatetool] create table HF_PERSON (...G_DAT_DATUM VARCHAR2(20), T_DAT_DATUM VARCHAR2(20), FK_DAT_ZUS_WERT NUMBER(19)...

I don't know exactly but for sure @Embeddable and @Entity on the same class is not supported today

Thank you for your tip, but I don't think that it is the solution.

Well the tip shows that your mapping is not correct :)

Well, but it works with @Entity and @Embedabble. He generates the table.

But I can't explain myself, why hibernate embeds the attribut if I leave out the ManyToOne-relation...

Nobody an Idea?
