[jira] [Updated] (OPENJPA-2536) FetchGroup is not returning lazy fields.

["Heath Thomann (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OPENJPA-2536?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Heath Thomann updated OPENJPA-2536:
-----------------------------------
    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
