"Encountered unmanaged object in persistent field" error while merging object
tree
----------------------------------------------------------------------------------
Key: OPENJPA-714
URL: https://issues.apache.org/jira/browse/OPENJPA-714
Project: OpenJPA
Issue Type: Bug
Affects Versions: 1.2.0, 1.1.0
Environment: Fedora Linux 6
java version "1.5.0_11"
Reporter: Ekin Sokmen
I get following error while merging a persisted entity A after adding new child
entities to it. The following relation exists between entities: A -> (many to
many) B -> (one to many) C. If I add "cascade= {CascadeType.MERGE,
CascadeType.PERSIST}" to ChainEntityC.chainEntityB field It works.
My opinion is the cascade type on entity C should not be necessary because C is
the last entity in the chain and should be cascaded from A to B to C. Cascade
from C to B does not sound logical. The information is already given using
foreignkey and cascase annotation.
The test code is attached and works if you copy it to openjpa-persistence-jdbc
test module.

org.apache.openjpa.persistence.InvalidStateException: Encountered unmanaged
object in persistent field
"org.apache.openjpa.persistence.relations.ChainEntityC.chainEntityB" during
flush. However, this field does not allow cascade persist. Set the cascade
attribute for this field to CascadeType.PERSIST or CascadeType.ALL (JPA
annotations) or "persist" or "all" (JPA orm.xml), or enable cascade-persist
globally, or manually persist the related field value prior to flushing. You
cannot flush unmanaged objects or graphs that have persistent associations to
unmanaged objects.
