Atmosphere 0.8.3 and bug in sample samples\jquery-pubsub\

[xserge]

Hello Everybody.
I just installed atmosphere 0.8.3, and have same questions to run-time functionality of sample application samples\jquery-pubsub
Project that I’m implementing will use similar functionality that has this sample that’s why I’m asking
Below the test case for Firefox.

1. Deploy this sample on web server apache-tomcat-7.0.23
2. open url http://localhost:8080/atmosphere-jquery-pubsub/ on NEW !!! instance of Firefox 9.0.1 or 8…
3. enter topic to subscribe test1
4. choose transport protocol “http streaming”
5. Publish message “Message 1”
6. Nothing is shown below text “Real Time PubSub Update”
7. Change transport protocol to “long pooling”, press button “Switch transport”
8. Publish message “Message 2”
9. Appeared response “Message Received: message 2 sent trying to use long-polling but detected transport is long-polling” below text “Real Time PubSub Update”
10. change transport protocol to “http streaming”, press button “Switch transport”
11. Publish message “Message 3”
12. Appeared new response “Message Received: message 3 sent trying to use streaming but detected transport is streaming”
    My question is why nothing was responsed on step 6 however on step 12 this protocol works fine ?

When I’m trying to open this application on Opera 11.60 after step 4 I’m receiving very long text text in browser started from.

Message Received: <!-- --------------------------------------------------------------------------------------
And so on…
But after next steps as described above I’m receiving
Message Received: gmessage 3 sent trying to use streaming but detected transport is streaming
Message Received: message 3 sent trying to use streamin but detected transport is streaming
Message Received: message 2 sent trying to use long-polling but detected transport is long-polling
Message Received: message 2 sent trying to use long-polling but detected transport is long-polling
Message Received: message 2 sent trying to use long-polling but detected transport is long-polling
As you see message 2 duplicated 3 times and message 3 twice with leading character “g”
Please help sort out the problems

My question is Why http streaming doesn't work but works only after I use long pooling at first step and after that I use http streaming ?

I'm unable to reproduce that issue with Atmosphere 0.8.6. Closing
