Hi!

One of my protocols is connected to a server, and with the output of that I'd like to send it to the other protocol.

I need to access the 'msg' method in ClassA from ClassB but I keep getting: exceptions.AttributeError: 'NoneType' object has no attribute 'write'

Actual code: http://pastebin.com/MQPhduSY

Any ideas please? :-)
