Does it work if you set the validator explicitely?
widgets.SingleSelectField(

Use a chained validator:
class MySchema(validators.Schema):
"""Validator schema for offer search form."""
...
start = validators.All(
validators.DateValidator(today_or_after=True),
validators.DateTimeConverter(format=my_date_format))
end = validators.All(
validators.DateValidator(today_or_after=True),
validators.DateTimeConverter(format=my_date_format))
...
chained_validators = [DatesOrdered('start', 'end')]
class DatesOrdered(validators.FieldsMatch):
"""Tests that the dates in the given fields are ordered.
Useful for testing if start dates are not later than end dates.
Pass the list of field names in as 'field_names'.
"""
messages = {
'invalidNotOrdered': _("Date should be later")
}
date_validator = validators.All(
validators.DateValidator(today_or_after=True),
validators.DateTimeConverter(format=date_format))
def to_date(self, value):
try:
return (value
and self.date_validator.to_python(value) or None)
except validators.Invalid:
return None
def validate_python(self, field_dict, state):
last = self.to_date(field_dict[self.field_names[0]])
errors = {}
for name in self.field_names[1:]:
current = self.to_date(field_dict.get(name))
if current is None or last is None:
continue
if current < last:
errors[name] = self.message('invalidNotOrdered', state)
if errors:
error_list = sorted(errors.iteritems())
error_message = '<br>\n'.join(
['%s: %s' % (name, value)
for name, value in error_list])
raise validators.Invalid(error_message,
field_dict, state, error_dict=errors)
Hope this helps.
