You might not have got the table structure right.... I usually mess  
things up when I try to create the tables by hand.  I usually let  
openjpa create tables and if I don't like the results add annotations  
until I get something I like (or identical to an existing schema if  
starting with that).

There are always lots of possible causes for problems :-)

I think that the easiest way to figure out what is wrong is to call  
entityManager.flush() right before your method exits.  This is what  
the synchronization is doing, and if your code does it you should have  
no problem seeing the error message.
