    FacesContext.getCurrentInstance() returns null in @Observer

    Chun Shin Newbie

      Hi,


      I have an @Observer method in an application scoped POJO bean and another conversation scoped SFSB like below:


      mySFSB:



      @Stateful
      @Name("mySFSB")
      @Scope(ScopeType.CONVERSATION)
      public class MyBean implements MyBeanInterface {
      ...
      
        public void methodA() {
          
          doSomeWork();
      
          Events.instance().raiseAsynchronousEvent("eventToObserve", param1, param2);
      
        }
      ...
      }
      



      Another component listenerPojo:



      @Name("listenerPojo")
      @Scope(ScopeType.Application)
      public class MyListenerPojo {
      ...
      
        @Observer("eventToObserve")
        public void process(String param1, String param2) {
      
          FacesMessage msg = someMessage;   
          doSomethingWithParams(param1, param2);
      
          FacesContext fc = FacesContext.getCurrentInstance();
      
          fc.addMessage(null, msg);
      
        }
      
      ...
      }
      



      The problem I'm facing here is that FacesContext.getCurrentInstance() returns null. Why is that? Is it because FacesContext is tied to the methodA request and the asynchronous method is running in a new thread? So, how can I access FacesContext?


      I'm just trying to implement something like what Leo had as an example in this post.


      Can someone please explain me?


      Thanks for your help in advance!
