If you query across entity groups (an entity is it's own entity group unless you explicitly set a parent) you may get entities in query results who's properties don't match the query predicates. http://code.google.com/appengine/articles/transaction_isolation.html You can either duplicate the filtering in your own code, or put the entities into groups and use ancestor queries. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
