thank you so much for your hints anthony, the error didn't appears anymore,
but the validation is not run
def __date_comparation(form):
if request.function == 'booking_add':
if form.vars.from_date > form.vars.to_date:
form.errors.to_date = 'To Date must greater than From Date'
i know there is a mistaken on my validation code, could you give me a
pointer how to fixed it?
thank you very much
