Nothing obvious immediately springs to my mind as to why this might
happen. Would you be able to provide us with a test case that produces
this problem so we could troubleshoot it?

Hi all,
I wrote a small app to look at openejb and am having an issue with one of
the relationships.
Before posting too much code I wanted to see if anything is obviously wrong.
The application has about 5 tables, I'm creating one row and building a
OneToMany association to another pre-existing entity, this all works without
issue. The next step in my test case was to update the OneToMany to another
pre-existing entity. All of the fields are already populated and I'm
invoking the setter on the entity. Once this is done, I invoked the merge
method on the Injected entityManager. The object returned from this is in
tact, and has the association, but one of the fields in the associated
object is set to null.
I'm working in OpenJPA 1.1, OpenEJB3.1, database is Postgres.
The code is inside a local Stateless session bean method.
The foreign key association for the onetomany is updated, and if I invoke
the finder to reload the object, it all loads properly, and the null field
is populated properly.
finally, in order to ensure this was an openejb problem and not something
specific to openjpa, I broke the code out of the stateless session, and ran
the same code with the transaction management in place without openejb.
Basically, the entity ended up with the proper field value after the merge.
thanks for any info/help.
