[Grok-dev] Using zc.sourcefactory.basic.BasicSourceFactory for a schema.List

Have you tried something like this:

class IFoo(Interface):

    foos = schema.List(
        value_type=schema.Choice(title=u"Foo", source=YourSource())

This specifies that the "foos" attribute will be a list that only can contain values retrieved from the source.

Hope this helps.
