Sorry it took a little while to get back to this thread. Is there a reason why you want to expose the discriminator column as a persistent property (you have the column TYPE mapped as an enum & as the discriminator col). I think this is causing the problems you're seeing.
I haven't checked the spec to see if this is expressly forbidden, but I'd definitely say it's unusual. -mike -- View this message in context: http://openjpa.208410.n2.nabble.com/problem-using-subclass-object-as-query-parameter-tp5506089p5519053.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
