Re: message used serializer that is not accepted: 4

Now, when I add the line :

Pyro4.config.SERIALIZER = 'pickle'

to my client, the client says:

Traceback (most recent call last):
  File "/Users/richard/Desktop/MyPython/CsClientNS.py", line 62, in <module>

    raise data
Pyro4.errors.ProtocolError: message used serializer that is not accepted: 4

and the *name server *has the same message:

RMA:~ richard$ python -m Pyro4.naming -n 10.0.1.4

    raise errors.ProtocolError("message used serializer that is not
accepted: %d" % msg.serializer_id)
ProtocolError: message used serializer that is not accepted: 4

BTW, the server has the following line :

Pyro4.config.SERIALIZERS_ACCEPTED.add('pickle')
