I am running the lastest ganymede Eclipse/EMF/Teneo on linux. Using
mysql 5.1.
I have a simple containment relationship where A contains B. When I
create A, add to resource, then create B and set A as the container via
setB(A) call in EMF I get the following exception:
org.hibernate.PropertyValueException: not-null property references a
null or transient value: NamedEquipmentList.facility
at org.hibernate.engine.Nullability.checkNullability(Nullabilit y.java:95)
at
org.hibernate.event.def.AbstractSaveEventListener.performSav eOrReplicate(AbstractSaveEventListener.java:313)
at
org.hibernate.event.def.AbstractSaveEventListener.performSav e(AbstractSaveEventListener.java:204)
at
org.hibernate.event.def.AbstractSaveEventListener.saveWithGe neratedId(AbstractSaveEventListener.java:130)

org.hibernate.event.def.DefaultSaveOrUpdateEventListener.ent ityIsTransient(DefaultSaveOrUpdateEventListener.java:195)
at
org.hibernate.event.def.DefaultSaveOrUpdateEventListener.per formSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:117)
....more
I have explicitly added B to the list of B's in A and set all attributes
in both objects with no luck.
A may contain 1-many B BTW.
Thanks,
Mark.

Hi Mark,
As an extra: here is also some background info for this type of exception. This type of exception occurs because there
is a reference to another object which is not yet persisted (known to hibernate).
There are two solutions:
1) first persist the refered-to object. Although this can sound impractical many times (in case of many-to-one
relations) the business logic works this way already, i.e. master data is persisted/created before creating/entering
transactional data.
2) If the association has specific cascade annotations set then hibernate will traverse the association and persist the
refered-to object (no exception in that case) before persisting the refering object.
For setting cascade annotations see my previous post.

Mark,
You can pass them to the datastore, the class PersistenceOptions has constants with the correct name of the options. See
here for a complete set of the options:
http://www.elver.org/hibernate/options.html
Or you can annotate the NamedEquipmentList.facility efeature with a ManyToOne with cascade options set.
Hmm, the only strange thing to me is the point when you get this exception, exactly when doing setB(A)? And the
NamedEquipmentList was already persisted/saved (you have called resource.save before doing setB(A))?

Martin,
Thanks.
No, the exception is on the first call to save the resource. The objects
are created and populated and all the references set, then save is
called. The db is empty, so all the objects in this case are created at
one time.
Mark.
