Hi Tim, It sounds like you need to detach the fetched entities so that they can still be accessed once the pm is closed. You can configure JDO to do this for you automatically using:
<prop key="datanucleus.DetachOnClose">true</prop> Could I see your jdo config file? You might need to detach each member of the result collection manually. At one point I seem to recall that the entities had to be moved into a collection from the result set but I need to confirm that this is correct. Also, this question might be better suited for the Google App Engine for Java forum: http://groups.google.com/group/google-appengine-java Thank you, Jeff On Tue, Jun 9, 2009 at 12:15 PM, Tim Wickstrom <timwickst...@gmail.com>wrote: > > Hello, > > I am building a function that queries the datastore and returns the > results of the query.
