Hi Matt!

Good thought, I tried that first, since the example show you doing it that way.  Unfortunately I get the following error:

                 There is no method with the name 'dispatchEvent'.

Any other ides would be appreciated!

Take out the dispatcher.dispatchEvent, just leave it as dispatchEvent.
You don't need a dispatcher property at all.

Subject: [flexcoders] ChangeEvent

Hello!

I am trying to get a change event working on a value object, but I just
can
not seem to get a change to occur.

Does anyone have a working example using Chnage Event?

Here is the code I have so far....

import mx.events.*;

// ActionScript Document
[ChangeEvent("configNameChanged")]

class edu.psu.uaim.data.Configuration
{
      public var currentConfig: XML;
      private var _configName: String = null;
      private var dispatcher:EventDispatcher;
     
    private static function staticConstructor():Boolean {
       EventDispatcher.initialize(Configuration.prototype);
       return true;
    }

    // Load an EventDispatcher
    private static var EventDispatcherDependency = EventDispatcher;

    private static var staticConstructed:Boolean = staticConstructor();

      [ChangeEvent("configNameChanged")]
      public function get configName(): String {
            Echo.debug("Config Name Get");
            if ((_configName == null) && (currentConfig!=null) &&
(currentConfig!=undefined)){
                  var node:XMLNode =
lookup("configuration.configName");
                  _configName = node.firstChild.nodeValue;
            }
            return _configName;
      }
     
      public function set configName(name: String): Void {
            _configName = name;
            setText("configuration.configName", name);
             dispatcher.dispatchEvent({type:"configNameChanged"});
      }
}
