> 2), I don't pass objects between PMs. Well I can only comment on your example, which closes the PM after persist (so the object goes to hollow then to transient), and *then* you check on field values. Things will be nulled unless retainValues is set. See http://www.datanucleus.org/products/accessplatform/jdo/object_lifecycle.html for a more user friendly abbreviated form of the JDO spec object lifecycle.
> I just get the object in another PM by its PK, is that wrong Closing the PM is correct, and nothing wrong with getting an object by its id. The thing is though, once you've got the object by the id, you must access the values via getters otherwise they will be null ;-) And you could easily look in the db viewer to see if things were persisted in the first place -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
