Timers are normally not necessary. You need to have a clear understanding of the application lifecycle and its events. I don't know when your onInit is getting called, but if it is after a request for data has been sent, that's too late, you need to do it before the request.

Ok, I might be onto something here.... I added trace statements in all handlers and contructors, etc.... And the order my traces come back are: Controller getNewsData onInit The order my traces SHOULD come back are: Controller onInit getNewsData Since my event listeners are setup in my onInit, and if they are being added after my initial dispatchEvent is sent... well obviously they will not be called..... So as a test I changed my onInt from: private function onInit( event:Event ):void { //setup event listeners /*systemManager is where event listener hangs out defines the relationship between event and handler*/ systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT, handler_GetNewsEvent ); systemManager.addEventListener( AddNewsEvent.ADD_NEWS_EVENT, handler_AddNewsEvent ); systemManager.addEventListener( NewsDataLoadedEvent.NEWS_LOADED_EVENT, handler_NewsLoadedEvent ); getNewsData(); trace("onInit"); } To: private function onInit( event:Event ):void { //setup event listeners /*systemManager is where event listener hangs out defines the relationship between event and handler*/ systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT, handler_GetNewsEvent ); systemManager.addEventListener( AddNewsEvent.ADD_NEWS_EVENT, handler_AddNewsEvent ); systemManager.addEventListener( NewsDataLoadedEvent.NEWS_LOADED_EVENT, handler_NewsLoadedEvent ); //getNewsData(); //dispatchEvent(new GetNewsEvent(GetNewsEvent.GET_NEWS_EVENT)); // Set a timer since the below function does not seem to get fired. var myTimer:Timer = new Timer(1, 1); myTimer.addEventListener("timer", getNewsData); myTimer.start(); trace("onInit"); } So I essentially setup a timer object to fire once like a second later, and it works. So now this does in fact work as expected, but the method does not seem "proper" to me. How would others get around this? Just do it the way I did? Or is there a more "proper" and "elegant" solution for this? DNK On 24-May-08, at 9:09 PM, Alex Harui wrote: > > Who's dispatching and how? > > > > When does the control get instantiated?
