@Version annotated Field not included in SELECT (prepstmnt)

Hello,

I'm having an issue in openJPA 1.2.1 with a entity model as follows:

@Entity
@Table(name = "PARTNER", schema = "PART")
@NamedQuery(name = "getPartner", query = "SELECT p FROM Partner p where 
p.partKey = :partKey")
public class Partner
{
    @Id
    @Column(name = "PART_KEY")
    private BigDecimal partKey;

    @OneToMany(mappedBy = "partner", fetch = FetchType.LAZY)
    private List<PartnerRolle> rollen;
}

@Entity
@Table(name = "PARTNERROLLE")
public class PartnerRolle
{
    @EmbeddedId
    private PartnerRolleKey key;

         @Version
    @Column(name = "VERSION")
    private BigDecimal version;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "PART_KEY")
    private Partner partner;
}

When I ask for a Partner and later on call getRollen(), in the 
corresponding SELECT (prepstmt), the Column VERSION of PARTNERROLLE is NOT 
queried (not listed in the SELECT). When I remove the @Version annotation, 
it works corerctly, thus the VERSION is filled with the correct value. It 
only works as expected, when I do NOT set @Version to that column. 

I doubt this is correct behaviour, cause even though its a simple query, 
ALL annotated columns should be returned, whether or not they changed. I 
was relying on the return of the VERSION field and ran into a 
NullPointerException because the BigDecimal was not correctly instatiated.

Any suggestion, even if it is "this is correct behaviour, because ..." 
would be appreciated.

Thanx,

Best regards,

Heiko
