Re: Problems with Formencode Msgs, Unexpected Inputs

Thank you for your quick feedback. On the schema, allow_extra_fields
actually got it to stop complaining about fields that I didn't care about.

A followup question (hopefully my last), how do you explicitly order the
execution of validatiors in a schema. For example, i want the password
validator to fire off before the password_confirm FieldsMatch validator.

Thank you,
nym
