Hi,
I have a hack that works. I generated the Peer classes with the primary key
in tact. I then removed the "if ( !obj.isNew() )" lines ass well as the
bodies of the setPrimaryKey methods. Finally I remove the
setPrimaryKeyMethod() method.
This is seems to work but it is UGLY. I don't have any suggestions for a
better fix at this stage :-(
