Hi Hongjin, We encountered a similar problem in another scenario, the only difference being that in our case, after merge, OpenJPA incorrectly concludes that a preexisting entity is new, at the time of commit, and errors out early. So instead of the PersistenceException you got, we get an ObjectExistsException. But the cause seems to be the same. We're looking into it.
Thanks for the analysis - it definitely helps. Dinkar 2008/10/15 Hong Jin Lu <[EMAIL PROTECTED]>: > > hi, folks: > > 1. My env is : WPS6.1, DB2 9.0, OpenJPA 1.2.0 > > 2.
