Re: Event Model from Scratch

I have 2 events so far.  A GetAdmin and a RenderAdmin.

class GetAdminHandler extends DefaultBaseEventListener {

public void handleControlEvent(ControlEventContext context) throws  
EventException, ServletException, IOException {

       log.debug("Admin Get!");

       BaseEvent event = context.getEvent();
       DispatchQueue queue = context.getQueue();
       queue.addEvent(new RenderAdmin(event));
     }
   }


I then have a RenderAdminHandler with a handleControlEvent method that  
starts with another log message, which never gets shown ( and that's  
where i get that error message).

I am coming from a background that used Barracuda over a year ago, so I  
wonder if there have been drastic changes to the implementation of the  
Event Model.

Also, I attempted to follow the BConfig tutorial, but I found a few  
broken links and got discouraged.
