I have ATVocabularyManager installed in a plone 3.2 site, a custom content-type with a multipleselectwidget which uses a NamedVocabulary

        vocabulary=NamedVocabulary("""branche"""),

'branche' is there is the vocabulary manager and the same setup works in 3.1.x

But in 3.2 i get this attribute error

Issue state: Unconfirmed → Confirmed

Can confirm this bug on 1.4.2. It's fixed on trunk, however.

Until the next release comes up you can use the following part in your buildout to use the current trunk instead of the released 1.4.2 egg (you can use a fixed revision too with this recipe)::

  [eggcheckouts]
  recipe = infrae.subversion
  as_eggs = true
  urls =
      http://svn.plone.org/[…]/trunk Products.ATVocabularyManager

and include it before zope2::

  parts =
      eggcheckouts
      zope2


@jensens: shall we release a 1.4.3 with this single fix or will you release 1.5 soon anyway?


Background
----------

Products/Archetypes/Field.py(474) is checking for IVocabulary the z3 way::

  IVocabulary.providedBy(value)

ATVM 1.4.2 relies on an old style interface for IVocabulary::

  __implements__ = (IVocabulary,)

Archetypes must have changed the vocabulary to be a z3 style one one of the last releases.

The trunk version of ATVM already makes NamedVocabulary implement IVocabulary.
(see http://dev.plone.org/[…]/namedvocabulary.py)

added a buildout to ATVocabularyManager repos so developers can easily set up a sandbox.
it contains an example of how to use ATVM trunk in a plone3.2 buildout:

How would one get the trunk version installed via easy_install? (if given the above URL to the trunk version, it fails with error 403 forbidden). Thanks...
