When developing server-client software, on the client i call the method
getTrafficDate, but on the server end, i got nio is
None(d2=d.addCallback(lambda object: object.callRemote("getNIOTrafficInfo",
node, nio)))
,so, what's the key point?
Thanks all!

nodelist = self.interfacenio_dict.keys()

for node in nodelist:

if len(interfaces):

if nio is not None:

d2=d.addCallback(lambda object:
object.callRemote("getNIOTrafficInfo", node, nio))
d2.addCallback(self.setTrafficSpeed_Tap, node,
interface)
trafficDataList.append(d2)

server end

print nio
if nio.name==nioName:

Bug info is:
