I have working with JPA on little desktop system. The problem is after the system updates a table 4 or 5 times correctly, the sixth time updates wrong, then the seventh time works well, until after 10 times it fails again once or twice more.
Details: Use JPA 2.0 with eclipselink and Netbeans 7.0.1. I'm using mysql.
I hope can you help me.
Thanks
