whats the purpose of the eventListener inside the constructor? init
is being implicitly called within the class... just dispatch the
event, and set up a listener in your FLA

Still doesn't work. If you look at the code the class fired the
event before deleting itself. Anyway I simplify it without the die
() method:
//
import mx.events.EventDispatcher;
//
//
class EventTry {
//
//members;
//event functions;
private var dispatchEvent:Function;
private var addEventListener:Function;
private var removeEventListener:Function;
//
//fired events;
public var onEvent:Function;
//
//
public function EventTry() {
EventDispatcher.initialize(this);
//here I define "onEvent";
this.addEventListener("onEvent", this);
init();
}
private function init() {
dispatchEvent({type:"onEvent", target:this});
}
}
and in the fla,
import EventTry;
//
var eventry:EventTry=new EventTry();
eventry.onEvent=function(){
trace(""onEvent fired"");
}
I make this class just as an example. Other classes I do before in
the flashmx2004 ide run well.
Please, try to look at it again,
Thanks,
Javier.

Hi Javier,
This is because you've got things happening in the wrong order:
- You create your EventTry() object, which calls init()
- Init fires the event, but onEvent is still undefined
- Init then calls die()
- Die() deletes the EventTry object
- You then set onEvent to your function - after everything else
has already
happened.
You need to set the onEvent object _before_ you fire the event to
have
anything
meaningful happen.
I can't understand how your old classes would have worked, looking
at this
code. Perhaps you're doing something slightly differently now?
Hope that helps,
Ian

Hello, I'm having troubles implementing the EventDispatcher class
with
flash8.
I do the same I use to do before, but now the class doesn't fired
the
event. Here is a sample class:
___
import mx.events.EventDispatcher;
//
class EventTry {
//event functions;
private var dispatchEvent:Function;
private var addEventListener:Function;
private var removeEventListener:Function;
//
//fired events;
public var onEvent:Function;
public function EventTry(){
EventDispatcher.initialize(this);
this.addEventListener("onEvent",this);
init();
}
//
private function init(){
dispatchEvent({type:"onEvent", target:this});
die();
}
private function die(){
removeEventListener("onEvent",this);
this=null;
delete this;
trace("EventTry die");
}
}
___
And here is the fla code:
import com.mg.temp.EventTry;
//
var etry:EventTry=new EventTry();
etry.onEvent=function(){
trace("onEvent fired");
}
//end
___
Here I doesn't get the "etry. onEvent" function fired. Also no
error,
it just ignore the statement.
Curiously my older classes run well with such a code.
Any help would be appreciate,
thanks,
Javier.
