I donno If this is the right place to post my query, yet am posting.
Am using DWR 3 rc1 in our chat Application and it runs on Jetty 6.1.5.
When the chat comes in, We load the chat in SWT Browser Component. When there are mutliple interactions, each chat interaction will be loaded in tabs of SWT Browser.

I need
-> one DWR Connection in the SWT Browser to keep the user available for chat.
-> one connection for each chat.

The problem is,
I can keep the user available for chat and the connection is using Comet mode.
once the chat connection is established, The DWR connection to maintain the availability will be killed (with dwr.engine.setActiveReverseAjax(false);) and the connection for sending and receiving the messages will be maintained in Comet mode. Once the Chat is over, the Window (SWT Browser tab) will be unloaded. On unload again I am killing the reverse ajax(using dwr.engine.setActiveReverseAjax(false);)

When the next chat comes, The connection will be maintained in Polling mode

The 3rd chat is going on Piggy back mode.

I just dont understand why this is happening!

- >Does DWR have any limitations that there cant be more than 1 DWR connection in a browser?

( I noticed the same thing happen in Firefox also with a small difference.First one in Comet,next simultaneous chats in Polling mode but never in piggy back. It goes wrong with FF only with simultaneous connections.)

- > Is SWT Browser a supported environment for DWR to run?
- > Do I need more configuration for this to work? What am I missing?

Any help would be appreciated! thanks in advance.

heres in my web.xml

<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
<init-param>
<param-name>activeReverseAjaxEnabled</param-name> 
<param-value>true</param-value>
</init-param>

<init-param>
<param-name>crossDomainSessionSecurity</param-name> 
<param-value>false</param-value>
</init-param>

<init-param>
<param-name>maxWaitAfterWrite</param-name>
<param-value>-1</param-value>
</init-param>

<init-param>
<param-name>allowScriptTagRemoting</param-name>
<param-value>true</param-value>
</init-param>

I tried with <init-param>
<param-name>maxWaitAfterWrite</param-name>
<param-value>500</param-value>
</init-param>

also in my web.xml. but not sure why this happens! Why the modes are getting changed like that !!
