Hi, I'm trying to import and use the email.Message.Message class in a zope 'Script (Python)'. I have the following security assertions in my product code:: from AccessControl import allow_module, allow_class from AccessControl import ModuleSecurityInfo ModuleSecurityInfo('email.Message').declarePublic('Message') from email.Message import Message allow_class(Message) As a result, I can successfully import like:: from email.Message import Message I can even create an instance and call most methods on it:: m = Message() m.set_payload('read that') However, when I try to use the mapping interface, I get an error. For example, the following:: m['from'] = 'tim@example.com' produces a traceback like:: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.PythonScripts.PythonScript, line 323, in _exec Module None, line 6, in AAA - <PythonScript at /test/AAA> - Line 6 Module RestrictedPython.Guards, line 96, in handler TypeError: object does not support item or slice assignment Does anyone have any idea what the problem is?
