 /**
 23  
  * Adapter class that combines a target object (typically, a component) with a
 24  
  * {@link org.apache.tapestry.listener.ListenerMethodInvoker}. This is the
 25  
  * bridge from listener method names to listener method invocations.
 26  
  * <p>
 27  
  * TODO: It would really be nice if we could get the location of the listener
 28  
  * binding into thrown exceptions. As implemented, as best, it will be the
 29  
  * location of the &lt;page-specification&gt; (or &lt;component&gt;) of the page
 30  
  * (or component) containing the listener method.
