> Key: OPENJPA-162
> URL: https://issues.apache.org/jira/browse/OPENJPA-162
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Affects Versions: 0.9.6
> Environment: Using PostgreSQL 8.1 as the database
> Reporter: Nick Johnson
> Fix For: 0.9.7
>
>
> Using the following annotation:
> @OneToMany(mappedBy="root", fetch=FetchType.LAZY)
> @OrderBy("objectId ASC")
> private List<Message> messages;
> I get the exception "Cannot order "net.spatula.tally_ho.model.MessageRoot.messages" on "objectId", because that field is not in the default fetch group. You can only order on fields that will be selected when the related object is loaded."
> I should certainly hope that the primary key of the related object is going to be selected when the object is loaded:
> @Id
> @Column(name = "object_id")
> private long objectId;
