exception

Hi. I'm catching

... Null primary key encountered in unit of work clone ...

exception in eclipselink(2.0.2 with 2.0 jpa) literally meaning that id in my entity is <=0 (for primitive types). Though debug here states that everything's fine and I have nothing to worry about. My AS is glassfish v3. Can any one point out what may cause such behavior?
