Subject: [flexcoders] custom event not added
Hi there,
I have a controller that is adding my custom event
listeners, but
for
some reason my event handler was not being fired.
My original code was (snippet):
(in controler)
//constructor
public function FlexbController()
{
//turn the key, start it up
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
}
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();
}
And I had trace statements in all of my handlers... this is
how i
noticed things were not working as they should.
SO I added a simple check like (in my FlexbController
constructor):
if
(systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT,
handler_GetNewsEvent ))
{
trace(true);
} else {
trace(false);
}
And I obviously am getting false.
Ideas?

Re: [flexcoders] custom event not added
ok, this is how my app is setup
:: app.mxml ::
has a:
xmlns:controller=Flexb.controller.*
controller:FlexbController/
That is how my controller is instantiated.
:: FlexbController.as ::
public class FlexbController extends UIComponent
in my constructor I have:
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
then in my onInit function I have:
systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT,
handler_GetNewsEvent );
along with a call to another function:
getNewsData();
(this one is called without issue).
In that function I dispatch the custom event in question:
dispatchEvent(new GetNewsEvent(GetNewsEvent.GET_NEWS_EVENT, null,
false, false));
So when dispatch it should go to a handler function called
handler_GetNewsEvent.
And it is that event handler that never seems to be processed. I had a
trace statement that never seems to show. And in that function there
are some remoting calls that I never see happening in service capture.
And that is where my app seems to fail.

Re: [flexcoders] custom event not added
Josh,
FYI, I got around the error, I had to use:
mx.core.Application.application.dispatchEvent(new
GetNewsEvent(GetNewsEvent.GET_NEWS_EVENT, null, false, false));
But event when targeting in this way as you suggested, it still did
not help dispatch the event..

Re: [flexcoders] custom event not added - almost solved.
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?

RE: [flexcoders] custom event not added - almost solved.
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.

Re: [flexcoders] custom event not added - almost solved.
Yeah that is what I thought.
my onInit is called in my constructor with:
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
The requests for data are usually called after other adding of the
events, but within the same function (onInit).
I think I will just ad my addEventListener calls direct in my
constructor and see what happens there.

Re: [flexcoders] custom event not added - almost solved.
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.

And the order my traces come back are:
Controller

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,

systemManager.addEventListener( NewsDataLoadedEvent.NEWS_LOADED_EVENT,

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

Re: [flexcoders] custom event not added - almost solved.
Ok mate, here's the problem:
public function FlexbController()
{
//turn the key, start it up
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
trace(Controller);
}
What you need, is this:
public function FlexbController()
{
//turn the key, start it up
Application.application.addEventListener(
FlexEvent.CREATION_COMPLETE, onInit );
trace(Controller);
}
The reason for this, is the way CREATION_COMPLETE is dispatched - which is
from the bottom of your display tree upward. It has to be this way, because
it's dispatched only after all the children of a component have already had
CREATION_COMPLETE dispatched. So first it is dispatched on all instantiated
UIComponents that don't have any children. Then (probably on the next frame,
but ask Alex) it's dispatched on their container components, and so on and
so forth until finally (as far as we care) it's dispatched on your root
Application. It might be then dispatched on a few containers up to the
systemManager, but again Alex would know better than me.
Now what happens in your case, CREATION_COMPLETE is dispatched on your
FlexbController, and then you're dispatching the GET_NEWS_EVENT immediately.
But, the current instance of FlexbController is not yet part of the
displayTree, because it hasn't been completely added to the Application's
children yet. So the event has nowhere to bubble to - and never reaches the
Application, or the SystemManager.
But, if you defer onInit() until CREATION_COMPLETE is dispatched on the
Application itself, you know that the display tree is complete (in its
initial layout at least), and you can safely dispatch the event and have it
bubble all the way to the top of the tree at SystemManager.

Subject: [flexcoders] custom event not added
Hi there,
I have a controller that is adding my custom event listeners,
but
for
some reason my event handler was not being fired.
My original code was (snippet):
(in controler)
//constructor
public function FlexbController()
{
//turn the key, start it up
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
}
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();
}
And I had trace statements in all of my handlers... this is
how i
noticed things were not working as they should.
SO I added a simple check like (in my FlexbController
constructor):
if
(systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT,
handler_GetNewsEvent ))
{
trace(true);
} else {
trace(false);
}
And I obviously am getting false.
Ideas?

RE: [flexcoders] custom event not added
Who's dispatching and how?
When does the control get instantiated? Could it be after
creationComplete?
If the controller is not a UIComponent, it will not get a
creationComplete.

Subject: [flexcoders] custom event not added
Hi there,
I have a controller that is adding my custom event listeners, but
for
some reason my event handler was not being fired.
My original code was (snippet):
(in controler)
//constructor
public function FlexbController()
{
//turn the key, start it up
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
}
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();
}
And I had trace statements in all of my handlers... this is how i
noticed things were not working as they should.
SO I added a simple check like (in my FlexbController
constructor):
if (systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT,
handler_GetNewsEvent ))
{
trace(true);
} else {
trace(false);
}
And I obviously am getting false.
Ideas?

Re: [flexcoders] custom event not added
If you're getting a runtime error accessing Application.application you'll
need fire to clean this up, methinks.

That added an error:
Access of undefined property Application

The only thing i can think of after looking at that is that your
controller (whatever that is) is not part of the display tree? Try
replacing dispatchEvent() with
Application.application.dispatchEvent() and see if it works then.

It is dispatched like this (in function in my controller):
dispatchEvent(new GetNewsEvent(GetNewsEvent.GET_NEWS_EVENT, null,
false, false));
the null is used for an object (if I need to pass data with my event).
In this particular case I did not.
My actual event class looks like:
package Flexb.events
{
import flash.events.Event;
public class GetNewsEvent extends Event
{
protected var _data:Object;
public static const
GET_NEWS_EVENT:String=GetNewsEventType;
public function GetNewsEvent( type:String,
data:Object = null,
bubbles:Boolean=true, cancelable:Boolean=false ):void
{
_data = data;
super(GET_NEWS_EVENT,true,false);
}
public function get data():Object
{
return _data;
}
}
}

ok, well that explains that part, however either my event is not
added, or my event handler is never called. My trace statements
never show up
So I guess I still am wondering if anyone has any ideas
