Michael Vorburger commented on OPENJPA-953:
-------------------------------------------
I actually found a work-around, for the attached test, do as follows: No
DictLanguageLabelId extends DictLabelId (and no @IdClass on
DictLanguageLabelEntity), and make DictLabelId not abstract. Then add the
following to the DictLabelEntity to "double map" that "object_dict_id" column
(which is also mapped in the DictLanguageLabelEntity subclass), and remove the
@Id from the forLanguage in DictLanguageLabelEntity:
@Id
@Basic(optional = false)
@javax.persistence.Column(name = "object_dict_id", nullable = false)
private long objectRef;
and add a public long objectRef; to the DictLabelId (with updated equals() and
hashCode()). seems to work, but is clearly a work-around for this bug...
