Your problem can be summarized by "storing acquisition wrappers (of persistent objects) across requests".

You cannot store them in the ZODB as acquisition wrappers cannot be stored there. Currently, the ZODB silently unmantles acquisition wrappers. They may be rebound on access -- but this will not give you the original acquisition context and behaviour can be drastically different.
hello, again, I have rearranged in my product now, so that I pass along dictionaries to populate the classes and using a cmf-tool to provide the interface for the various methods of the classes. I am returning objects wrapped in __of__(self), ie. class Person(Acquisition.Implicit): def __init__(self data): ... PersonObject = Person(data).__of__(self) return PersonObject If I want to pickle, store and later reuse PersonObject, I suspect that this also creates a similar to my original one, where I wanted to store ZODB-references in the PersonObject. So should I, when pickling and storing the PersonObject, store PersonObject.aq_base rather than just PersonObject?
