Massimo,
> Why isn't the problem solved by the validator that I posted?
In my model the openinghours table reads like:
db.define_table('openinghours',
Field
('company',db.company,default='',notnull=True,ondelete='CASCADE',
writable=False, readable=False),
Field('day',db.day,default='',notnull=True,ondelete='RESTRICT'),
Field('from_tijd',type='time',default='',notnull=True),
Field('to_tijd',type='time',default='',notnull=True),
migrate='openinghours.table')
...
db.openinghours.from_time.requires=IS_TIME(error_message='should be
UU:MM!')
db.openinghours.from_time.widget=timeplain
db.openinghours.from_time.requires=is_less_than(request.vars.to_time)
db.openinghours.to_time.requires=IS_TIME(error_message='should be
UU:MM!')
db.openinghours.to_time.widget=timeplain
In the less_than_class I changed the following line, because of the
format of the
opening hours:
other=datetime.datetime.strptime(self.value,'%H:%M')
When I expose the functions that create or update opening hours, I get
an error ticket:

I don't understand why argument 1 is None.

When the user enters from_time 10:00 and to_time 22:00 the form should
be accepted,
10:00 < 22:00 is True
When the user enters from_time 10.00 and to_time 02:00 the form should
NOT be accepted.
10:00 < 02:00 is False.
I hope this explanation of my problem helps you help me solve it.
