    Seam throws exception after timer has finished execution

    Amit Sachde Newbie

      I get the following exception once a timer has finished execution. It's not hindering what I do but wanted to know is this something due to my timer.

      Thanks.
      JPDL Excerpt:



      System.out.println("In state wait!!!");




      System.out.println("Did the timer fire???");





      System.out.println("Leaving wait state!!!");
