Hi Kevin, thank you VERY much for your answers. I tested your second proposal for solution and it works like a charm! But one drawback here: we lose portability because as you said the annotation is OpenJPA specific.
Could some OpenJPA official please update the FAQ (http://openjpa.apache.org/faq.html) "Can OpenJPA reorder SQL statements to satisfy database foreign key constraints?" Maybe the @ForeignKey solution would be helpful for other desperate developers as well... -- View this message in context: http://openjpa.208410.n2.nabble.com/Constraint-violation-using-OneToOne-relationship-tp6978223p6981835.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
