I'm trying to use Eclipselink History Policy according to the following example: https://wiki.eclipse.org/EclipseLink/Examples/JPA/History
However, in my case the updates/deletes are not being saved as expected, id field is saved as null as follows:
1)insertion
EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID START_DATE END_DATE
1 Bob Way 55000 6 2010-06-10-12:00 null
2) update
EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID START_DATE END_DATE
1 Bob Way 55000 6 2010-06- 10-12:00 2010-06-10-12:03
null Bob Way 50000 6 2010-06-10-12:03 null
3) deletion : nothing happens
I've used mysql and postgresql to perform this tests. My history table is not using any constraints or identity fields. Is this the right behavior of history feature? Is there something else to set up?
