[web2py] checkboxes and radio widget failed with multiple validators

Hello,

I've met a problem with checkboxes and rzdio widgets:

The following works:
Field('status', 'string', requires=IS_IN_SET(STATUS_TYPE, multiple=True),
        widget=SQLFORM.widgets.checkboxes.widget)

However if I add another validator, it doesn't work anymore :
Field('status', 'string', requires=[IS_IN_SET(STATUS_TYPE, multiple=True),
IS_NOT_EMPTY()],
        widget=SQLFORM.widgets.checkboxes.widget)


Any suggestion ?
