Hi Christian,from your information,I change the code and it works! I add the propagation="none" to the <s:link>, and it show me a exception that beanB @In can not find the object @Out from beanA,I suppose that's because they are at different context,means a new conversation context is created for beanB. Then I change the @In and @Out to @Out(scope=ScopeType.SESSION) @In(required=false, scope=ScopeType.SESSION) then everything works fine. Thanks a lot,Christian. Cheers!
