Re: [eclipselink-users] Problem with attributes of a ElementCollection in Query
|
This seems to be an issue with JPQL and ElementCollections. Please log a bug
for this issue.
As a workaround using a Criteria Query or an EclipseLink Expression query
should work. Or you can change the ElementCollection to a OneToMany and an
Entity.
