Kasper Sørensen closed METAMODEL-91.
------------------------------------
Resolution: Duplicate
Thank you for reporting the issue. It is actually a duplicate of METAMODEL-85,
so I'll close this one and I have also raised the priority of the other issue.
> isNotNull () is actually isNull() and isNull() isn't work in UpdateCallback
> of JdbcDataContext
