[web2py] issue with list of validators

[Marco Prosperi]

hi all,
still have problems with validators. Why a field defined so in db.py

..
Field('myfield','string',requires=[IS_NOT_EMPTY(error_message=T('my
custom message')),IS_IN_LIST(['first','second'])]),
..

doesn't show a drop down list in a SQLFORM but shows 'my custom
message' after submit if left empty?

thanks in advance,
Marco
