Hi people,
I have a problem with Hibernate when use Query by Example and the object have a composite-id. When i call the criteria.list() the list return all objects of table. The hibernate dont add composite-id in where clause.

Class:
public class ProdutoComposite implements Serializable{
private String idProduto;
private String idEmpresa;
private String descricao;
private double valorUnitario;

/*
Here i implements hashCode equals and acessors methods

*/

}




Hibernate version: 3.0.5

Mapping documents:
<hibernate-mapping>
<class name="com.csi.prototipo.produtocompositeid.ProdutoComposite" table="rodrigo_composite_id">
<composite-id>
<key-property name="idProduto" column="ID_PRODUTO"/>
<key-property name="idEmpresa" column="ID_EMPRESA"/>
</composite-id>
<property name="descricao" type="string" column="descricao"/>
<property name="valorUnitario" type="double" column="valor_unitario"/>
</class>
</hibernate-mapping>


Full stack trace of any exception that occurs:
None


Name and version of the database you are using: Oracle 9i and Driver ojdbc14.jar

The generated SQL (show_sql=true):
Hibernate: select this.ID_PRODUTO as ID_PRODUTO0_, this.ID_EMPRESA as ID_EMPRESA0_, this.descricao as descricao0_, this.valor_unitario as valor_un4_0_ from rodrigo_composite_id this where (1=1)

I got the same problem with composite id and Criteria...
I am looking for a solution too.
Anybody ?
