The issue is definitely present: Object fields do not enforce their schema invariants.

I have reviewed the patch, and like the idea. I am concerned that obscuring the Invalid eror raised by the invariant check is going to lead to hard-to-debug errors, so I haven't committed the patch. Instead, I am assigning the Christian for confirmation.

Changed in zope.schema:
assignee:	nobody → Christian Theune (ct-gocept)
status:	New → Confirmed

Just for some clarification, I'm wrapping exceptions raised during Object field's invariant check to differentiate them later from exceptions raised by other fields.
