Subject [jira] Created: (OPENJPA-249) problem using enum with @Enumerated annotation in Query

problem using enum with @Enumerated annotation in Query
-------------------------------------------------------

                 Key: OPENJPA-249
                 URL: https://issues.apache.org/jira/browse/OPENJPA-249
             Project: OpenJPA
          Issue Type: Bug
          Components: query
    Affects Versions: 0.9.7
         Environment: Windows XP, WAS 6.1
            Reporter: Daniel Gajdos


Situation description:
@Entity
public class Application {
...
	@ManyToOne(optional = false)
	@JoinColumn(name = "C_APPLICATION_STATUS",
		nullable = false)
	@ForeignKey(name = "FK_APPLICATION__APPLICATION_S")
	private ApplicationStatus applicationStatus;
...}

@Entity
public class ApplicationStatus {
	public static enum Code {
		created
	}
	@Id
	@Column(name = "C_CODE")
	@Enumerated(EnumType.STRING)
	private Code code;
}
And now the problem:
When executing query "SELECT a FROM Application a WHERE a.applicationStatus = :status" with
parameter q.setParameter("status", ApplicationStatus status); everything works fine. 
But when trying to call the query like "SELECT a FROM Application a WHERE a.applicationStatus.code
= :package.ApplicationStatus.Code.created " it fails with: Attempt to query field "package.ApplicationStatus.Code.waiting"
from non-entity class "null".
Is there any way to create a query with built in enum value? I found a similar issue on http://forums.oracle.com/forums/thread.jspa?threadID=506389&tstart=45
