Zope does not restrict an External Method in any way.

Usually, this means that the object looks like
a dictionary but is in fact a different object.

However, your traceback is weird:

  It seems to indicate that
  "HTTPRequest.HTTPRequest.__getattr__('__setitem__')
  was called.
  However, "HTTPRequest.HTTPRequest" does have a "__setitem__"
  attribute. Therefore, Python will never call
  "__getattr__" automatically to resolve "__setitem__".

  Something else must have called "__getattr__" inadequately.

  The upper part of traceback (which you dropped) should
  tell you where this calls happens.
