so either use eager fetch... not a good idea for large objects. OR use a VTO pattern (http://java.sun.com/blueprints/patterns/ TransferObject.html) to populate ur presentation objects. this enables the persistence layer transaction to be abstracted away from presentation. VTO pattern is more usefull. -lp -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
