2. Re: NPE during persisting an EB

jquery Oct 19, 2007 3:39 AM (in response to jquery)

Yes, actually it was due to empty public void create() method in Home object. But I still don't know why. When I commented it out the error disappeared. Recently I've updated JBoss Seam to CR2 version and when I uncommented this method today the error no more appears. Thank You for your intrest.

Best regards,
jquery
