Thanks very much for this. Would it be possible to include the two
portal_types vocabularies in CMFDefault?
I got the vocabulary in my view class but then I got an Assertion
Error relating to it:
2008-02-13 21:16:34 ERROR Zope.SiteErrorLog http://localhost:8080/new/b/@@edit.html
Traceback (innermost last):
Module ZPublisher.Publish, line 119, in publish
Module ZPublisher.mapply, line 88, in mapply
Module ZPublisher.Publish, line 42, in call_object
Module zope.formlib.form, line 769, in __call__

Module Products.CMFDefault.formlib.form, line 117, in setUpWidgets
Module zope.formlib.form, line 379, in setUpEditWidgets
Module zope.schema._field, line 244, in bind
AssertionError
Looking at the source:
def bind(self, object):
"""See zope.schema._bootstrapinterfaces.IField."""
clone = super(Choice, self).bind(object)
# get registered vocabulary if needed:
if IContextSourceBinder.providedBy(self.vocabulary):
clone.vocabulary = self.vocabulary(object)
assert ISource.providedBy(clone.vocabulary)
elif clone.vocabulary is None and self.vocabularyName is not
None:
vr = getVocabularyRegistry()
clone.vocabulary = vr.get(object, self.vocabularyName)
assert ISource.providedBy(clone.vocabulary)
looks like I'm a victiom of copy & paste programming (again! ;-) The
vocabulary definitely doesn't provide ISource but I can't seem to get
this to work: either by adding it as a parameter to implements() or in
ZCML leads to a lookup error:
ComponentLookupError: (<InterfaceClass
zope.schema.interfaces.IVocabularyFactory>,
'cmf.UserFriendlyContentTypes')
mm, guess I need to double check my declarations. I thought that
implements(IMyInterface)
is equivalent to provides="...IMyInterface" in ZCML
BTW. this is probably academic but I noticed the top of the types.py is
from zope.app.schema.vocabulary import IVocabularyFactory
Is there a reason for not importing the interface directly?
I'll also be reading up ISource in Philip's book.
