[rules-users] Exception in JBRMS with 4.0.2

[kissro at lidp.com]

Hello,

I upgraded from 4.0.1 to 4.0.2 and am getting the following errors when
I try to bring up the BRMS in the web-based gui. I get the "JBoss Rules"
screen but it's blank; it doesn't have the login boxes.  The console
shows:

[STDOUT] ERROR 09-10 (Contexts.java:flushAndDestroyContexts:
           could not discover transaction status
[STDOUT] ERROR 09-10 (StandardWrapperValve.java:invoke:278)
           Servlet.service() for servlet default threw exception
           java.lang.IllegalStateException: Cannot create a session after
                                          the response has been committed

at org.jboss.seam.servlet.ServletRequestSessionMap.put(ServletRequestSessionMap.java:87)
at org.jboss.seam.servlet.ServletRequestSessionMap.put(ServletRequestSessionMap.java:25)

Also, when I run my java program that reads the .drl file, builds
WorkingMemory, fires the rules, etc., I get this exception:

[STDOUT] ERROR 09-10 (Contexts.java:flushAndDestroyContexts:
         could not discover transaction status
[STDOUT] Error calling UnderwritingRule java.lang.ClassCastException:
         java.util.Collections$EmptyMap

If I revert back to the 4.0.1 jar files and 4.0.1 brms .war file,
everything works fine again.  Could someone tell me how to resolve these
errors or point me in the direction to start looking?  Did I just not
copy in a new file or update somewhere?

Thanks,
Rod
