Hello,
I have two entity classes. ClassA and ClassB. ClassB has a property ClassA, so in my tables (autogenerated by persistence.xml) there is a foreign key from ClassB to ClassA_id I first persist my ClassA entity. Thereafter I persist my ClassB entity. Thereafter I persist again my ClassB entity (because a field changed). The strange thing is, when I run this program the very first time, it fails with the error below. After failing a first time, it works fine !!! Exception in thread "main" <openjpa-2.0.0-r422266:935683 nonfatal store error> org.apache.openjpa.persistence.EntityExistsException: An object of type "src.ClassB" with oid "0" already exists in this context; another cannot be persisted. Why is this failing the first time? And why not the other times? Thank you! -- View this message in context: http://openjpa.208410.n2.nabble.com/An-object-of-type-src-StatusUpdate-with-oid-0-already-exists-in-this-context-another-cannot-be-persi-tp5030272p5030272.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
