Checks whether the EventDispatcher object has any listeners registered for a specific type of event. Indicates whether an object has a specified property defined. WebcreateEventDispatcher must be called when the component is first instantiated — you can't do it later inside e.g. a setTimeout callback. This links dispatch to the component instance. Notice that the App component is listening to the messages dispatched by Inner component thanks to the on:message directive.
