[Zope3-dev] Problem with partialAnnotatableAdapters

[Florian Lindner]

Hello,
I try to connect a schema field with a dublin core metadata field using 
partialAnnotatableAdapterFactory.
I'm logged in as zope.Manager.

My configure.zcml:

    <adapter
        for=".link.Link"
        provides="zope.app.dublincore.interfaces.IZopeDublinCore"
        factory=".link.factory"
        />

My link.py:

[...]
from zope.app.dublincore import annotatableadapter

factory = annotatableadapter.partialAnnotatableAdapterFactory(["description"])

the description field is defined in the interface:

    description = TextLine (
        title = u"Description",
        description = u"Description which mirrors the DC metadata.",
        required = False)

What is wrong there?

The backtrace is pasted at the end of the mail.

Thanks,

Florian
