Hi Jacob, This time I got a little clear, but I still don't know how to use it in my following code. In my previous studyList, the more codes like this: (I think this is typical search bean)@Stateful | @Scope(CONVERSATION) | @Name("studyList") | public class StudyListAction implements StudyList { | | ... | @Create | @Begin | public init() { | ... | } | | @Begin(join=true) | public String findStudy { | ... | } | | @Begin(join=true) | public void nextPage() { | ... | } | | @Begin(join=true) | public void previousPage() { | ... | } | | @Begin(join=true) | public void firstPage() { | ... | } | | @Begin(join=true) | public void lastPage() { | ... | } | | ... | } Should I use <s:conversationPropagation propagation="none"/> in each method? Like this: <h:commandButton value="List Study" action="#{studyList.findStudy}"> | <s:conversationPropagation propagation="none"/> | </h:commanButton> | | <h:commandButton value="Next Page" action="#{studyList.nextPage}"> | <s:conversationPropagation propagation="none"/> | </h:commanButton> | | <h:commandButton value="Last Page" action="#{studyList.lastPage}"> | <s:conversationPropagation propagation="none"/> | </h:commanButton> | | ...... | Thank you for any help!
