Just to clarify - the row in "note" exists already, what I am trying to 
do is update the row.

The code is like this:

Note note = NoteManager.getInstance(x);

Unfortunately my torque.log has stopped working for some reason, so I 
cannot get access to the sql statement it is passing to postgresql.

What I need to know in the meantime is whether this sort of thing is 
possible - does torque support null objects in columns?
