Hi!
I've a Zope BTree called answers. It contains PersistentMapping objects:
self.answers[userid] = PersistentMapping(value=value,
comments=comments)
value can be a string, a list or a dictionary
what happen exactly if I do: question.answers[a_userdid] =
question.answers[another_user_id] ?
From my (poor) tests they seems not to share anything, I mean I can
modify question.answers[a_userdid] and question.answers[another_user_id]
is untouched.
Is this true? Should I beware of something?
I can't reproduce your reported behavior::

from BTrees.OOBTree import OOBTree
from persistent.mapping import PersistentMapping
answers = OOBTree()
john = PersistentMapping(value=John's value,
... comment=John's comment)
answers['john'] = john
answers['fred'] = answers['john']
answers['fred'] is john
True
print john
{'comment': John's comment, 'value': John's value}
answers['fred']['value'] = Fred's value
print john
{'comment': John's comment, 'value': Fred's value}
