    Not evaluated @Column Annotation

      Hello,


      I am using SEAM 2.0.1 on a JBoss 4.2.2 with EJB3 and PostgreSQL 8.2.6. I generated a project using seam-gen and added an entity containing a field physicalDiskId. By a Column-Annotation this field is mapped to a column physicalvolume_id. Here the been:


      @Entity
@IdClass(ExtentPK.class)
@Table(name="extent")
public class Extent implements java.io.Serializable {
    
     private static final long serialVersionUID = 1L;

     // <editor-fold defaultstate="collapsed" desc="EJB CMP Fields.">
    @Id
    @Column(name = "id", nullable = false)
    private Long id;
    
    @Id
    @Column(name = "physicalvolume_id", nullable = false)
    private Long physicalDiskId;
    
    @Column(name="virtualposition")
    private Long virtualPosition;
    
    @Column(name="physicalposition")
    private Long physicalPosition;
    
    @Column(name="status")
    private Long status;
    
    @Column(name="virtualvolume_id")
    private Long virtualVolumeId;

[...]



      Deploying the application I get the following errormessage:


      15:37:13,075 WARN  [ServiceController] Problem starting service persistence.units:ear=mda2008.ear,jar=mda2008.jar,unitName=mda2008
javax.persistence.PersistenceException: org.hibernate.HibernateException: Missing column: physicalDiskId in public.extent
     at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:720)
     at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:127)



      So it tries to find a column named after the field in the bean instead of the name I told him. Why does this happen?


      The table extent looks like following:


      CREATE TABLE extent (
        id bigint,
        physicalvolume_id bigint,
        virtualposition bigint,
        physicalposition bigint,
        status bigint,
        virtualvolume_id bigint,
        PRIMARY KEY (id, physicalvolume_id)
);



      Can anyone tell me where my failure is?
