net.sf.hibernate.HibernateException: Illegal attempt to associate a
collection with two open sessions
I get the preceding error when...
A user issues a query to select an object holding a collection and at the
same time another user updates that object.
Is it true, that in the same SessionFactory, you cannot update and read an
object in 2 different Sessions
which contains a collection, at the same time?
I saw posted back in January...but did not find a solution. Should I just
ditch the one-to-many association?
"This exception occurs when (during a flush) Hibernate discovers a new
reference to a collection that is currently "owned" by another open
Session. You should verify that you are closing all your Sessions. (It
is nothing to do with the query itself; Hibernate simply decided that
the query required that a flush precede the
Query.) "
my config...
<set name="batches" lazy="false" order-by="batch_no asc">
<key column="survey_id"/>
<one-to-many class="com.lsr.pamm2.generic.model.SurveyBatch"/>
</set>
Thanks,
Joseph Toth
