[Zope3-Users] zope.schema Question

[Tim Cook]

I have a class attribute defined in an interface as such:

    description=Object(
        title=_(u"Description"),
        description=_(u"Description of the activity."),
        required=True,
    )

I used Object because this attribute can be one of several different
class instances.  

But I get an error:
TypeError: __init__() takes exactly 2 non-keyword arguments (1 given)

When the implementation is attempting to import the interface.

But if I enter a default=None or
 
    description=Object(None,
        title=_(u"Description"),
        description=_(u"Description of the activity."),
        required=True,
    )

I get:
 File
"/home/tim/buildout-eggs/zope.schema-3.4.0-py2.4.egg/zope/schema/_field.py", line 453, in __init__
    raise WrongType
zope.schema._bootstrapinterfaces.WrongType

I do not have these issues using many of the other zope.schema types.

Thanks,
Tim
