Description

If I use openjpa.DetachState=fetch-groups and detach an entity with a lazy loaded list, this list gets reset to null.

An example:

class @Entity Person {
private String name;

@OneToMany(mappedBy = "group", cascade =

{CascadeType.ALL}

)
private List<Subscription> subscriptions = new ArrayList<Subscription>();
...}

I load the Person and access the subscriptions inside a transaction. I get a person instance with e.g. 3 subscriptions.
If I now close the EntityManager and my person gets detached, the subscriptions list is suddenly null!
