Only strings, integers, floats, "booleans", dictionaries, tuples, lists, and special "datetime", base64, and fault objects can be passed via XML-RPC. Anything else is too complex. The spec at http://www.xml-rpc.com/spec is useful.

Also, xmlrpclib will marshall a class instance as a dictionary, using it's __dict__. This applies to instances of python classes, but not extension classes. Fixing this would be a bad idea: ObjectManager.objectItems would try to return your whole database.

I am experimenting with xml-rpc and Zope. Some Methods from the API work ok, but others return an error. A common error is:

Error Value: cannot marshal <extension class Acquisition.ImplicitAcquirerWrapper at 00C950F0> objects

I receive this error for example when for Zope 2.1.6 I execute: ObjectManager.objectValues Where as the next Method works ok: ObjectManager.objectItems

Maybe the to be returned info is to complex ?
