Hi,

I am using Jboss 7.1.1 Final and my application embeds Hibernate 3.5. 

When saving an object MyClass containing these 2 realtions, I have the following exception. 

@Entity

@Audited

public class MyClass{

@OneToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)

@JoinColumn(name = "user_id")

private User user;

@OneToMany(cascade = ALL)

@JoinColumn(name = "agent_id")

private List<AgentCode> agentCodes;

}

In AgentCode, I have the mappedBy attribute:

@ManyToOne

@AuditMappedBy(mappedBy = "agentCodes")

private Agent agent;

When agentCodes list is empty and firstly filled with one or several items, it works.  But when I try to save a third one, when the List is already containing AgentCodes, I get the exception. 

I have debugged the Envers code and for the User property, it doesn't use the temporary session of AuditSync but the SessionImplementor whose session is already closed.

Caused by: org.hibernate.SessionException: Session is closed!
