Hi Winston,
Sorry, I left for vacation Thursday evening and checked in that code in a
hurry without fully testing it. Several months ago the 'sqlIdName' method
was replaced by 'sqlSerialColumnName', and I didn't catch this before
committing my code. I've just fixed this in CVS, so you'll just need to
do an update to fix this.
peace,
Jason
