> We've encountered a problem using the PostLoad event to access a OneToMany Collection. 
> Attempting to access the Collection in the PostLoad event handler results in a LazyInitializationException being thrown by AbstractEntityManagerImpl. The stack trace is below:
> javax.persistence.PersistenceException: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed
> 	at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1235)
> 	at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:631)
> 	at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:585)
> I've attached a JUnit test case containing the classes and configuration. We're using Oracle 11g and Hibernate v3.5.3-Final, but the test case uses HSQLDB. 
> If there is any further information I can provide to help diagnose this then please let me know.
