Hi All,
Hibernate 3.2.4
JBoss 4.2.3
Firstly let me say I have solved this issue and I'm really looking for clarification as to the reason for the problem.
So I received a pretty standard stacktrace;
Code:
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.ecebs.multefile.configurator.validation.entities.Capability.properties, no session or session was closed

Under the following circumstances;
Single EntityManager
Call to SessionBeanA.create() method
Delegates lookup of existing entityA to SessionBeanB (via remote interface)
Still inside SessionBeanA.create() method associate entityA with newly created entityB, persist.
Still inside SessionBeanA.create() I try and access collection associated with entityA
I get the exception above!
When I change the call to SessionBeanB to use a local interface the problem is resolved.
I know that SessionBeanB uses the existing transaction created in SessionBeanA.create(), however apparently it is diffferent sessions!
1. Is my assumption correct?
2. If not does anyone know the real reason?
