Hello everyone! I hope someone can help me with this.. Deadline coming closer.. :|
I have a problem when mapping a Map<Entity, String>.

@MapKeyManyToMany(joinColumns={@JoinColumn(referencedColumnName="Pk")})
@CollectionOfElements
@Cascade({CascadeType.ALL})
public Map<CarBrand, String> getDepartmentCarbrandId() {
return departmentCarbrandId;
}

The problem is that the mapkey column(for CarBrand) in the database (postgres 8.2) becomes of bytearray type instead of mapping the Pk(for CarBrand as Long). I've tried different variations of @JoinTable(name="Pk") The Map persists but with the entity serialized. The owning Entity maps to PK and the String to Varchar.

I'm using JBoss 4.0.4 GA which I think has hibernate 3.2.0.cr4.

Any clues anyone? Extremly greatful for any insights.

Best regards,

Hi,

Have you made absolutly sure that all the annotation are either at variable/field or getter/method level. If you mix and match the level at which you place the annotations you run into problems when using relationships.

Upgraded to Jboss 4.0.5.GA Solved the problem. Used referenceName instead of name in the join column.
