My assumption is that an onvalidation callback has access to the
'fields' list as a local variable. (See code below.) Is that correct?
In pre-1.56 this worked, but in 1.56.1 it crashes with KeyError: 'id'
-- leading me to think that myvalidator() is passed a 'fields' list
that has ALL fields in the table, instead of the fields array that I
passed to SQLFORM -- which I think is how it should be.
Note that this is *not* mysql-related, it also occurs with sqlite.
Cheers,

if form.accepts(request.vars, session, onvalidation=lambda form:
myvalidator(form)):
