Subject Re: Issue saving entities with fields that reference read only data
Date Tue, 11 Mar 2014 16:42:54 GMT
If you are trying to persist an Entity that has a relationship to an
(readonly) Entity that already exists in your DB, you should ensure that
the existing Entity is a part of your persistence context (ie managed).
OpenJPA is most likely complaining because we encountered an unmanaged
field when persisting your non readonly Entity to the DB.

So :

ReadOnlyEntity e = em.find(...); // I assume this is different than what
you are currently doing.
NewEntity ne = new NewEntity();
ne.setRelationship(e);

em.persist(e);

Thanks,
Rick
