for future reference, and to help others:
- autocompletewidget requires an IQuerySource-providing object
- that needs to have a 'search()' method
- and then needs to be bound like this:
class myfancySourceBinder(object):
implements(IContextSourceBinder)
def __call__(self, context):
return myfancySource(context)
- then, use myfancySourceBinder() as the source for your
AutocompleteFieldWidget or AutocompleteMultiFieldWidget
Providing a search() method on an IVocabularyFactory object directly
does not work, or at least I found it impossible using grok.implements
