[jboss-user] [JBoss Seam] - @End from "join" ends all conversations - unexpected action

[Bernix]

I have two beans in conversation scope, beanA and beanB. beanA is backing pageA individually,and beanB is backing pageB individually.
beanA will begin the long-running conversation in pageA at first, then we jump to pageB, pageB will begin(join=true) beanB.
but when we end the joined conversation in beanB.done , the beanA is destroyed as well.....

beanA
@Stateful
  | @Scope(CONVERSATION)
  | @Name("beanA")
  | public class BeanA implements IBeanA {
  | 
  | 	public BeanA() {
  | 		System.out.println(">>>>>> BeanA is constructed.");
  | 	}
  | 
  | 	@Begin
  | 	public void init() {
  | 		System.out.println(">>>>>> BeanA is initialized.");
  | 	}
  | 
  | 	@End
  | 	public void done() {
  | 		System.out.println(">>>>>> BeanA is done.");
  | 	}
  | 
  | 	@Remove
  | 	public void destroy() {	
  | 		System.out.println(">>>>>> BeanA is destroyed.");
  | 	}
  | }


beanB
@Stateful
  | @Name("beanB")
  | @Scope (CONVERSATION)
  | public class BeanB implements IBeanB {
  | 
  | 	public BeanB() {
  | 		System.out.println(">>>>>> BeanB is constructed.");
  | 	}
  | 
  | 	@Begin(join=true)
  | 	public void init() {
  | 		System.out.println(">>>>>> BeanB is initialized.");
  | 	}
  | 
  | 	@End(beforeRedirect=true)
  | 	public void done() {
  | 		System.out.println(">>>>>> BeanB is done.");
  | 	}
  | 
  | 	@Remove
  | 	public void destroy() {	
  | 		System.out.println(">>>>>> BeanB is destroyed.");
  | 	}
  | }


home.xhtml
<s:link view="/pageA.xhtml" action="#{beanA.init()}" value="Go to beanA">


pageA
<s:link view="/pageB.xhtml" action="#{beanB.init()}" value="Go to beanB"/>


pageB
<h:form>
  | 	<h:commandButton action="#{beanB.done}" value="Done beanB"/>
  | </h:form>


pageB.page.xml
   <navigation from-action="#{beanB.done}">
  |          <redirect view-id="/pageA.xhtml"/>
  |    </navigation>


we do the following steps:
1. enter home page
2. link to pageA
3. link to pageB
4. click "Done beanB" in pageB

then we got the exception.....the log is:
16:31:46,333 INFO  [STDOUT] >>>>>> BeanA is constructed.
  | 16:31:46,458 INFO  [STDOUT] >>>>>> BeanA is initialized.
  | 16:31:49,458 INFO  [STDOUT] >>>>>> BeanB is constructed.
  | 16:31:49,489 INFO  [STDOUT] >>>>>> BeanB is initialized.
  | 16:31:56,129 INFO  [STDOUT] >>>>>> BeanB is done.
  | 16:31:56,145 INFO  [STDOUT] >>>>>> BeanB is destroyed.
  | 16:31:56,161 INFO  [STDOUT] >>>>>> BeanA is destroyed.
  | 16:31:56,254 INFO  [STDOUT] >>>>>> BeanA is constructed.
  | 

Why the @End in beanB.done() cause the beanA to be destroyed?
We would hope that resume to beanA when beanB is done.

I know we can use nested conversation in beanB,yes,nested conversation works OK.
I just wondering,if I join a conversation,how can I end it then resume to the previous long-running conversation?
