Description

I have found an issue with FetchGroups not returning 'lazy' fields. To describe, take this entity:

@Entity
@FetchGroup(name = "HardwareSimple", attributes =

{ @FetchAttribute(name = "status"), @FetchAttribute(name = "statusActive") }

)
public class HardwareStatus implements Serializable {

@Id
private String status;
private String statusActive;
private String condition;
private int connection;
...............

With this Entity, take the following scenario:

OpenJPAEntityManager openJpaEm = OpenJPAPersistence.cast(em);
openJpaEm.getFetchPlan().resetFetchGroups().removeFetchGroup("default").addFetchGroups("HardwareSimple");

HardwareStatus h1 = em.find(HardwareStatus.class, "Lost");
//h1.status contains "Lost" in the db.
assertEquals("Lost",h1.getStatus()); //this assert passes
//h1.connection contains '2' in the db.
assertEquals(2, h1.getConnection()); //this assert fails, 0 is returned by the getter.
//h1.condition contains "Used" in the db.
assertEquals("Used", h1.getCondition()); //this assert fails, null is returned by the getter.

The latter two h1.get* do not return the correct values. These fields are 'lazy' (i.e. not part of the FetchGroup) but should be fetched when requested. See the attached test for full details.

Thanks,

Heath
