I tried this, but I'm still having trouble.  Perhaps I'm missing something 
simple.  I have the following:

An IItem interface and a class Item implementation that's attribute 
annotatable.

The annotation interface and class are as follows:

class IItemMiscInfo(Interface):

    inStock = Bool(
        title=u"In Stock",
        description=u"Is item in stock?",
        default=True)

class ItemMiscInfo(Persistent):
    implements(IItemMiscInfo)
    adapts(IItem)

    def __init__(self):
        self.inStock = True

What am I supposed to use in the adapter directive as the factory?  If I 
put ".item.ItemMiscInfo", I get "TypeError: Missing 'provides' attribute" 
when starting Zope.  If I add provides=".interfaces.IItemMiscInfo", I get 
the following error when trying to access the editform:

  File "/usr/lib/zope-3.3.0_beta1/lib/python/zope/security/adapter.py", line 
84, in __call__
    adapter = self.factory(*args)
TypeError: __init__() takes exactly 1 argument (2 given)

The README says to do this:

  zope.component.provideAdapter(zope.annotation.factory(Item))

I can do that in a debug session and it works as expected, I just can't 
figure out the rest.

What am I missing?
