[Twisted-Python] newbie udp

[p@]

Hi list,
 
I tested the example given in the documentation. with the following
code:
 
class UdpServer (DatagramProtocol):
    def datagramReceived(self, request, address):
        print 'udp recieved:'+request
        response = '\x02'
        self.transport.write(response,address)
 
reactor.listenUDP(serverPort, UdpServer())
reactor.run()
 
if I send a udp packet to this server I get the following exception:
 
udp recieved:a
Traceback (most recent call last):
  File "C:\Python22\Lib\site-packages\twisted\internet\default.py", line
473, in

    _logrun(selectable, _drdw, selectable, method, dict)

    return context.call({ILogContext: newCtx}, func, *args, **kw)

    return func(*args,**kw)

    why = getattr(selectable, method)()

ead
    data, addr = self.socket.recvfrom(self.maxPacketSize)
  File "<string>", line 1, in recvfrom
 
socket.error: (10035, 'The socket operation could not complete without
blocking')
 
I am on win32 and using python 2.2 and this is twisted 1.0.5. What am I
doing wrong?
 
Cheers
