I should really do more tests befores saying that things work.

The, I get this error while using it like this:
class WidgetsToSomething(widgets.WidgetsList)
widget1 = ...
widget2 = Fields()
widget3 = ...

Putting Fields inside a list -- [Fields()] -- makes the widget disappear as
well as the error, so it doesn't work either. The same happens if I don't
instantiate the class...
So I believe that what I want is not possible, unfortunately... I'll put the
code back and live with it :-(
My real "class" is:
class WidgetsSelecaoFornecedores(widgets.SingleSelectField):
"""
Widget para a seleção de um fornecedor dentre os fornecedores
cadastrados e ativos.
Reparar que esta invocação deve ser colocada dentro de uma lista --
[WidgetsSelecaoFornecedores()] -- pois estou fazendo uma subclasse do
widget para permitir seu reuso em outros contextos.
"""
name = 'fornecedor'
label = _('Fornecedor')
css_classes = ['required']
options = fornecedores
validator = validators.Int(not_empty = True)
Thanks and don't worry with this... It is bringing more troubles than it
should. But we at least know that none of the approaches worked.
