[Grok-dev] zope.schema.Choice & unicode problem

[Christian Klinger]

Hello Marcel,

you can use vocabularies instead of values. Take a look on this
example it should help you:

def voc(*terms):
    return SimpleVocabulary([SimpleTerm(value, token, title) for value, 
token, title in terms])

[...]

    colors=Choice(title=_(u"The color"),voc(
       ('Fehler','Fehler',u"Fehler"),
       ('Änderung','Änderung',u"Änderung")
    ))

Let me know if it works for you...

Christian
