Comment 3 Robin Stocker CLA 2010-12-01 12:32:14 EST 
Only an insert is issued, like this:

INSERT INTO CALLBACKENTITY (ID, POSTPERSISTSTATE) VALUES (?, ?)
	bind => [1, null]

If you haven't done so, it is likely a good idea to go through the mailing lists or forums prior to posting these kinds of bugs.  The reason: There is a good chance someone will be able to provide you with a reasonable workaround.
Comment 5 Robin Stocker CLA 2010-12-06 09:02:59 EST 
A workaround is to call detach() before merge(). But that shouldn't be necessary, right? That's what this bug is about.
Comment 6 Tom Ware CLA 2010-12-09 09:11:22 EST 
Setting target and priority.  See the following page for the meanings of these fields:
