 Post subject: Repeated column in mapping

JBoss version:4.0.1 RC1


I have a composite primary key made up of two Integer fields and I was able to create a PK class from the JBoss EJB 3.0 example. However my situation is different from the example in that one of the fields of the primary key is the JoinColumn to another table. This causes Jboss Hibernate to return a error, "Repeated column in mapping"

According to Hibernate discussions this problem can be fixed by marking the OneToMany as "update=false, insert=false" however this doesn't seem to be part of the 3.0 spec.

Is there a Hiberate fix for this problem?

Thanks.

Thanks for the response. Here is an example

Code:
@Entity
public class CustomerFlight implements java.io.Serializable
{
   CustomerFlightPK pk;
   Flight flight;

   public CustomerFlight()
   {
   }

   @Id(generate = GeneratorType.NONE)
   @Dependent({
   @DependentAttribute(name = "id"),
   @DependentAttribute(name = "flight_id")
   })
   public CustomerPK getPk()
   {
      return pk;
   }

   public void setPk(CustomerPK pk)
   {
      this.pk = pk;
   }

   @Transient
   public String getName()
   {
      return pk.getName();
   }

   @ManyToOne
   @JoinColumns({@JoinColumn(name = "flight_id")})

   public Flight getFlight()
   {
      return flight;
   }

   public void setFlight(Flight flight)
   {
      this.flight = flight;
   }

}

You'll not be able to fix it using the EJB3 annotations. I think we should forbid what you want or enable the update/insert attribute at the spec level.

Should it be possible to create the relationship under the CustomerPK class instead and expose it throught @Transient methods to the Customer class?

You mean
Code:
@Transient public getLink() {
    getId().getLink();
}


Actually you can :-)

Emmanuel,

Did you get my example? I sent you an email where it doesn't work.

BTW. How do you upload attachements to this board?

Thanks,

Gray

There is no need for attachments of any kind. If you can not express an issue using the artefacts listed in our textarea form, it should not be discussed on a public forum until you isolate the problem further.

I doubt Emmanuel has the time to work on your application.

Thanks for your response however I'm not asking him to work on my issue. He responded to my posted with certain information about the capability of Hibernate that doesn't seem to match the reality of my experience. For the purpose of disseminating accurate information to your user community, it would be nice for you to actually provide verifiable information on this board.

Thanks,

Gray

Actually I hadn't had time to look at your case. You should report this bug to Bill anyway http://www.jboss.org/products/ejb3/jira.
