All Session Values NULL after [detectDuplicateNesting=true]

[lzj0428]

Hello,

We had a web site using JBoss and JSP/Servlet/JavaBean inside.
It seems fine, but suddenly, All Session Values/Objects lost after these 3 lines:

2005-11-21 15:42:05,712 DEBUG [org.jboss.util.NestedThrowable] org.jboss.util.NestedThrowable.parentTraceEnabled=true
2005-11-21 15:42:05,713 DEBUG [org.jboss.util.NestedThrowable] org.jboss.util.NestedThrowable.nestedTraceEnabled=false
2005-11-21 15:42:05,713 DEBUG [org.jboss.util.NestedThrowable] org.jboss.util.NestedThrowable.detectDuplicateNesting=true
.... (after this, Session Values become null)

Is there any way to solve it ? or where can I config to avoid this situation?
Thanks for help...
