[Grok-dev] Values from another document before rendering

[Adam Summers]

Hi Group,

I'm using grok 1.2.1, and I have a problem calling a vocab in an addform:

My vocabulary is as follows:

class AccountMasterVocabularies(grok.GlobalUtility):
        grok.implements(schema.interfaces.IVocabularyFactory)
        grok.name('accnt')

        def __call__(self, context):
                return(schema.vocabulary.SimpleVocabulary([
                        schema.vocabulary.SimpleTerm('01', 'term 1', u'Really'),
                        schema.vocabulary.SimpleTerm('02', 'term 2', u'Truly') ]))

(So I would expect the vocab to be registered as 'accnt', no?)

Then I have an Schema/Model as follows:

class IGLLine(interface.Interface):
        """A Line"""
        account = schema.Choice(title=u"Account", vocabulary='accnt')

class GLLine(grok.Model):
        """The implementation of the GLLine"""
        grok.context(GLLineContainer)
        grok.implements(IGLLine)
        account = None

However, I get a VocabularyRegistryError because the vocabulary is unknown (see below). What am I missing????

Thanks in advance,
Adam
