thanks for your answers:
Pierre, the StreamingQueryResult is not serializable. However, to my
understanding this problem is alleviated when you work with detached
objects since you call something like
Collection c = pm.detachCopyAll(resultList);
at the end and you are then returning the
The list is not a basic ArrayList but a class of Datanucleus that is
not serializable.
Really ? You mean an org.datanucleus.sco.backed.ArrayList that

I'm finding that it's nearly impossible to work with the detaching objects
style. I can't tell for sure what's happening other than when I add a
PersistenceCapable object to another PersistenceCapable object's collection
(i.e., the first one will be the child of the second one) that I get an
