I noticed last night that after putting some logging statements in onInterrupt and on onTerminated, the onInterrupt method was being invoked after 20sec~ or so. I checked the documentation for Ext.Ajax.request and there is a default timeout of 30sec. Close to what I was experiencing so today I'll try setting the timeout to a large number and work out sending the json message to the client.

did you figure it out? I'm interested to learn if ExtJS can work with

A tutorial kind of document like this one:

would be quite appreciated if you have time, of course :-)

I'll do more testing tonight to see if I made a mistake because that is a likely candidate so hopefully I find something tonight.Also, do I need the "event.getCometContext().resumeCometHandler(this);"
