#3317 closed defect (fixed)

Comet listeners are not removed when the connection is closed

When a script invokes cometd subscribe, a listener is added for this channel in dojo. However these listener are not invalidated when the server closes the connection. This causes the handlers called multiple times on reconnect.

I am not sure if it is the really intended behaviour.

Step to reproduce : function connect() {

dojox.cometd.init(null, "/comet/cometd"); dojox.cometd.subscribe("/messages", null, function(obj) {console.debug("Message from the server :", obj);}


function disconnect() {



function publish() {

request = {message:"New message"}; dojox.cometd.publish("/messages", request);


connect(); disconnect(); connect(); publish();

The publish will fire the handler twice.

(In [9410]) ensuring that disconnect cleans out subscriptions and backlogs. Fixes #3317
