Tore Halset resolved CAY-1206.
------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 3.0)
                   3.0M6

This was fixed for 3.0M6, but does not have support in the modeler. I do not know if this is useful at all from the modeler. It is very useful for automatic upgrade stuff.

> When adding a "not null" column to a table with rows, or when setting a column to "not null", there should be a way to tell DbMerger about the values that should be used instead of null for existing rows. 
> With this information, the merger should create sql like the following before setting the column to "not null".
> update table set col='the value' where col is null;
