[jboss-user] [JBoss Seam] - concurrent-request-timeout and odd NullPointerException

Hi all, I have a simple h:selectOneMenu with a child ajax4jsf support element to rerender a label "onchange." The menu has worked flawlessly until I increased the concurrent-request-timeout value from 500 to 2000 to resolve an unrelated issue. Now I'm consistently getting this exception when I change the value of the select: | 17:21:16,722 ERROR [ExceptionFilter] exception root cause | java.lang.NullPointerException | at

What are there implications in changing the concurrent request timeout? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4068494#...
