[Grok-dev] Grok and zc.vault

[Edu]

Hey, I'm building an app which has to use a versioning system,
zc.vault looks very good but I can't manage to get it working, I get the
following error:

ComponentLookupError: (<InterfaceClass zope.intid.interfaces.IIntIds>, '')

I also get the error when trying out the example in the README,

>>> from zc.vault.vault import Vault, Inventory
>>> from zc.vault.core import Manifest
>>> from zc.vault import interfaces
>>> from zope.interface.verify import verifyObject
>>> v = Vault()
>>> len(v)
0
>>> verifyObject(interfaces.IVault, v)
True

>>> i = Inventory(vault=v)
>>> verifyObject(interfaces.IInventory, i)

When I get here instead of gettint "True" I get:

verifyObject(interfaces.IInventory, i)

ComponentLookupError: (<InterfaceClass zope.intid.interfaces.IIntIds>, '')

Any ideas of what might be happening?

Thanks!
