[web2py] Radio widget doesn't work with IS_IN_SET validator?

[Alec Taylor]

I've got a simple field in my registration form:

Field('field_of_studies', requires=IS_IN_SET(['sciences',
'social-sciences', 'arts', 'business']),
widget=SQLFORM.widgets.radio.widget),

However when rendered on the page it only shows up as 4 radio buttons;
with nothing next to them. (no text)

How do I fix this?

Thanks for all suggestions,

Alec Taylor
