[jboss-user] [JBoss Seam] - debug.seam not able to load conversation context page

[alllle]

Seam 2.0.0GA in JBoss 4.2.2GA

It was working but suddenly, I cannot view the conversation debug page via the debug.seam?cid=xxx URL.

In browser, the "/debug.seam" still works. But when I click on the link "select conversation context" for a specific conversation, I got an error saying the "debug.seam" is not available. The link to the conversation context specific page is something like: 
/debug.seam?cid=xxx
where xxx is the conversation id. 

In the console, the following exception is dumped out:
