    using raiseTimedEvent / TimerSchedule

    Brian Cole Newbie

      I couldn't find a working example on the forums, so now I've got one, I thought I'd do the right thing and post.
      Note:
      1. I'm using a POJO here, and didn't change my components.xml at all. If I was in a EJB component, I guess I could have used the EJB (or quartz?) timer service, but what I have here is all I needed.
      2. Seam 2.0 and JBoss 4.2.2.
      3. The event stuff in Seam is great. Thanks Seam people!

          I've been using a variation of this in Seam 1.1.5.GA where my Asynchronous method returns javax.ejb.Timer, and I declare "@In Timer timer;" in my class, so I can cancel the Timer if I need to.

          However, in Seam 2.0.1.CR1, as soon as I declare "@In Timer timer;" in my class, Events.instance().raiseAsynchronousEvent() and Events.instance().raiseTimedEvent() don't generate events any more. I don't get any errors or anything, I just don't receive events.

          How do I use Events.instance().raiseTimedEvent() where I have access to the Timer object in Seam 2.0.1.CR1?
