In this code:
private function onInit( event:Event ):void
{
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");
}
You're calling getNewsData before you do the trace from your init() method,
so you're getting the order you want but it looks otherwise. Whenever I've
using this sort of trace statement to debug a process execution, I make it
the first line of the method, and I suggest it's a good habit to have :)
When you call addEventListener, it has an immediate effect. But when you
call dispatchEvent, it sits in a queue until all other processing for this
frame is completed. Alex can tell you whether it's run in the last part of
this frame, or the first part of the next, but it's neither here nor there.
If you're adding a handler, and then calling the code that dispatches that
event, you should still be receiving the event in your handler, leaving me
to believe that something else is the cause of your woes.
How big is your project? If it's a reasonable size (and doesn't contain any
business secrets or anything), zip it up and upload it somewhere, and I'll
download the whole thing and have a look- I'm sure I'll be able to figure
out what you're doing wrong.
