Hi Community,

I've a problem with LongPolling.
It is a little bit strange, because I already used this functionality until now.
Now I am receiving a NullPointerException for
"LongPollingMgr.add(m_longPolling);" (called on the constructor)
with
"DefaultLongPolling m_longPolling = new DefaultLongPolling();"
as an attribute.

I got this exception after the update of the latest (todays 2010(0)913) version of CC. But I'm not sure if this depends on the update.

regards,
Thomas

...yes, we added a bit (if the session "dies" then now all long polling threads are released)... - but this should not affect the general long polling management...

When do you add the ILongPolling instance? Is it possible that you do this in a situation wherer there has not been a session initialization yet?

Regards, Björn

I do it in the constructor of the UI class.
I think I have a session at this time - at least I have a sessionID

Code:

 public class SupervisorProgressUI extends InteractionUI implements Serializable {
 	...
 	
 	DefaultLongPolling m_longPolling = new DefaultLongPolling();
 	boolean m_longPollingRendered = false;
 	
 	public SupervisorProgressUI(IDispatcher dispatcher)
 	{
 		super(dispatcher);
 		try{
 			...
 			LongPollingMgr.add(m_longPolling);
 		}
          ....

regards

OK, thanks for the info.

Hmm, ...
we will check and provide an update short term (tomorrow morning), if this is fine with you.

Hi Björn,

no problem.
Let me know, if I can help you in any way.
Thanks in advance.

Community,

after direct support by CC:
The following entry was missing in the web.xml:

Code:

   <listener>
     <listener-class>org.eclnt.jsfserver.util.HttpSessionListenerDelegator</listener-class>
   </listener>

now it works.
Thanks
