Struts2 ActionContext and ValueStack?

My questions are:

1. In Struts2, does every action object have its own corresponding ActionContext and ValueStack?

In other words, for every new request a new action object is created. Does this mean every time a new action object is created, a new ActionContext and ValueStack also get created?

2. Consider this scenario:

Action1------1st req------->view.jsp------2nd req--------->action2.

So when a request comes for action1 a new object of action1 and corresponding ActionContext and ValueStack will get created.

From view.jsp (upon clicking hyperlink) a new request goes for action2.

Does this mean that previous ActionContext and ValueStack (related to action1) gets destroyed and a new ActionContext and ValueStack (for action2) gets created?

3. Suppose I store something in ActionContext (of action1) in view.jsp and then click on hyperlink for action2 (from view.jsp), will that data along with the ActionContext (of action1) get lost?

1. Yes

2. Yes after action execution clean up will be done.

   //SourceCode from StrutsPrepareAndExecuteFilter.
   
   //Cleans up a request of thread locals
   
   public void cleanupRequest(HttpServletRequest request) {
   
     Integer counterVal = (Integer) request.getAttribute(CLEANUP_RECURSION_COUNTER);
     if (counterVal != null) {
         counterVal -= 1;
         request.setAttribute(CLEANUP_RECURSION_COUNTER, counterVal);
         if (counterVal > 0 ) {
             if (log.isDebugEnabled()) {
                 log.debug("skipping cleanup counter="+counterVal);
             }
             return;
         }
     }
   
     // always clean up the thread request, even if an action hasn't been executed
     ActionContext.setContext(null);
     Dispatcher.setInstance(null);
   }
   

3.Yes, If you want that data available in the next action use chain(not suggestible).
