Fabio Maulo commented on NH-2668:
---------------------------------

In fact in your test you have:
                // Unsure if there is a cross-platform way to do this.
                // (Need to drop the "not null" constraint.)
                ExecuteSql(session, "alter table Info alter column Version INT");

                // ... and need to bypass NHibernate to insert the following rows, in order
                // to simulate rows in a legacy database that were "already there".
                ExecuteSql(session, "insert into Info values (1, 'Positive version')");
                ExecuteSql(session, "insert into Info values (0, 'Zero version')");
                ExecuteSql(session, "insert into Info values (null, 'NULL version')");
                ExecuteSql(session, "insert into Info values (-1, 'Negative version')");

> Reopening NH-2667 as a new defect since it appears that I cannot reopen it myself. NH-2667 was closed before I could even attach the test case. Please don't close this yet; let the test case speak for itself. 
> I tried using unsaved-value and it did not work. There are, in fact, bugs here.
