<persistence-context> - Subflow - LazyInitializationException

[iwtolall]

Hi all,

I use the <persistence-context> element in a flow definition which calls a subflow. The subflow does either change or create an object. After the subflow is ended and the control is again in the flow definition with <persistence-context> I get

org.hibernate.LazyInitializationException - could not initialize proxy - no Session

while continuing on the flow.

The session should not be closed due to calling a subflow after returning?
In case the session should still be active what can cause the termination?

Thanks for any suggestions.

Peter,

The session should not be closed after a subflow returns to a parent marked <persistence-context>. Are you using the Hibernate listener or the JPA one? Which version of SWF?

Thx for the quick reply Keith.

I'm using org.springframework.webflow.persistence.HibernateF lowExecutionListener
and
SWF 2.0.2.CI-499

Hi
I think I have the same problem as iwtolall.
I have a flow with the <persistence-context> element and this flow call a subflow. This subflow output a list of hibernate objets and when the main flow try to access to them, I obtain an exception :

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role : my.package.MyObject.myProperties, no session or session was closed

I'm using org.springframework.webflow.persistence.HibernateF lowExecutionListener and SWF 2.0.3.

How can I solve this problem ? Is it a bug ?

Hello, same problem on 2.0.5, any fix on the roadmap ?

I found this issue in the jira : SWF-360.

Just to let you know that I submitted to SWF-360 a version of the JpaFlowExecutionListener that propagates the persistence context to the subflow. Any feedback is welcome.
