Sorry :(

Now, I do that :

>>> class P(Persistent):
...     pass
...
>>> from zope.app.keyreference.persistent import KeyReferenceToPersistent
>>> from zope.app.keyreference.interfaces import IKeyReference
>>> from zope.app.testing import setup, ztapi
>>> from persistent.interfaces import IPersistent
>>> ztapi.provideAdapter(IPersistent, IKeyReference, KeyReferenceToPersistent)
>>> from zope.app.intid import IntIds
>>> u = IntIds()
>>> obj = object()
>>> obj = P()
>>> uid = u.register(obj)

What is it ? I've IPersistent adapter to IKeyReference. I don't
understand what is "zope.app.keyreference.interfaces.NotYet:
<__main__.P object at 0xb6969dec>" ?

Yes! I want it !

Thanks for your help,
