Also, I'd like to do more per cycle if my app finds itself running on a ninja machine :) Anyone have any tips for this sort of thing? Should I just be using the timer and striving for 1/4 of a frame measured in ms? What framerate are Flex SWFs set to run at normally?

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] Re: Importing SWC Files in FLEX
Hi Anuj, //An internal build error has occurred. Right-click for more information. I had difficulty in understanding exactly what was needed to use Flash assets and had similar errors. It doesn't help when the documentation varies so much on what to do. Unfortunately the Adobe PDF's have no publishing date written inside and so you often get information from out-of-date ones. I am able to use Flash Assets but my projects are all ActionScript projects rather than Flex projects. As a result I do not have to turn the asset into a Flex component by making it an extension of the UIMovieClip class. For example, on the stage I have a red dot with a radial gradient. I make it into a symbol and it goes in the library. It has to be either a button or MovieClip. Say I call it RedDot. I can delete the one on the stage. When I publish I make sure the SWC box is ticked in the publish settings. In Flex Builder 3 I right click the project, go to build options and add the swc. If I then type var rd:, suddenly RedDot is on the list of types I select it and hit return. So I finish up with var rd:RedDot = new RedDot and I can addChild(rd) and that's it. With Flex projects the only difference is that Flex needs to give the mxml compiler access to RedDot. It does this by agreeing an interface to it - this is just a set of agreed functions/methods that both sides agree on. This is the UIMovieClip - UserInterfaceToMovieClip (probably). So in Flash my RedDot has to extend UIMovieClip. If you have already done this, right-click the symbol in the library and check the properties to see this. If not, select the symbol and go to the Commands menu in Flash and choose Convert symbol to Flex component. This has three consequences, which you can just do manually yourself: 1. The fps is set to 24. 2. The Base Class is set to mx.flash.UIMovieClip. 3. The FlexComponentBase is added to the library. Note: I have just checked and found that the library symbol must have export for actionscript ticked before you Convert it, otherwise it doesn't do it. Now you can either right-click the symbol and export the swc, or publish and produce the swc. I have a swf with five symbols in it and when published my swc has five symbols in which I can use in Flex. I suggest you draw the simplest graphic, turn it into a MovieClip symbol for the library. Make sure export for actionscript is set in the library symbol. Select it and Convert to a Flex Component. Check the properties for the UIMovieClip class. Publish with SWC ticked. Import it, and it should be available. You don't need to write a class to go with it since Flash produces its own cutdown class for it when ti doesn't find one. I got the above error when I followed various guidelines and tried to do something more complicated. Fingers crossed for you! John

Thanks, I'll take a look at that. I dispatched the event because I

Thanks again for your suggestion.

Updating the dataprovider is costly. Make sure it only happens when

will do a lot of work.
XML is much slower than objects, so it may pay to convert to object.
Button already has logic for handling a selectedField in a dataprovider
item. Since CheckBox inherits from button, you might just be able to
use selectedField, or modify and piggy-back on its timing.

Subject: [flexcoders] Why is this renderer so slow?
I have created a checkbox renderer. My datagrid has 5 out of 8
columns that use it. The datagrid has only about 80 rows it it. When
using this renderer the performance of the datagrid is horrible.
Scrolling is extremely slow, click a checkbox is extremely slow. If I
swap out and use a normal mx:CheckBox for the renderer the performance
is just fine, but of course that doesn't work as it will not retain
the state of the checkbox when scrolling. Here is my code for the
renderer. I notice that many of these are re-executed whenever
anything happens to the datagrid. That includes just mousing over.
Thanks.

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 - 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?

[flexcoders] Detecting the Access of a Non-Existant Property
I thought I read somewhere that there is a way to intercept an attempted access of a non-existent object property. For example, suppose an attempt is made to access the property bar of an object foo which is an instance of the class FooBar (i.e. x = foo.bar). Further suppose that the property bar does not exist for foo. Is there a way to define a method in FooBar that will catch the attempt to access the non-existent property bar and return a value as if bar actually did exist? Even something similar to the way the prototype property works would be helpful (if it is scoped to the instance rather than to the class). Thanks.
RE: [flexcoders] Re: Button down event
Keyboard-only navigation is provided for by Flex. No other work is required to get it to work, so there isn't much doc on it. The doc covers what you need to get screen readers to work as that is not built-in. It is my understanding that we conform to accessibility guidelines, but that doesn't mean there aren't bugs. Most navigators switch tabs via arrow keys. Tabbing switches to the next focusable object, and Enter can activate a defaultButton. Using tab to switch between tabs is not an 80% case and, IMHO, would be unexpected by most keyboard navigation users. Buttons get highlighted as you tab to them to indicate that ENTER will activate them (assuming you've set a defaultButton somewhere). That's standard UI in Windows and Internet Explorer and probably other browsers and operating systems as well. If you think you've found problems with our accessibility support, including keyboard navigation issues, please file bugs and our accessibility experts will help the engineering team make the appropriate changes.

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.

With proxied calls though, it's a bit more complicated to solve. In the remoting case, your remote object method is generally just doing some local computation on the server and maybe hitting a database. It's simple to wrap this up in a Runnable and execute it asynchronously. In the case of the proxy service, we use the Apache HttpClient library to make proxied calls on your behalf, and this would be _much_ harder for you to wrap up in a Runnable to execute concurrently. I'd like to see us support async mode for the proxy service as well as for the remoting service, and the proxy service itself should be updated to use NIO to support making proxied calls that don't tie up a server thread for the duration of the proxy request. Right now, in BlazeDS, because Servlet IO is blocking, when you make a proxy service call that hits our server the servlet request handler thread has to wait for the proxy request to return before it can return. So you tie up the thread for the duration of the call which could take awhile. Would you mind logging an enhancement request for async proxy service support in our bugbase?

When these results get back to the browser and are passed back into the Player, they are dispatched to your ActionScript handling code as asynchronous events.

[flexcoders] Flex Profiler: Charts and Graphs not equal?
I'm having some issues with an app that potentially may be hitting the memory allocation maximum. I'm trying to figure out if the issue is that I'm hitting the maximum container size, the maximum Flash Player cache, or the maximum Browser cache (Firefox is default at 50MB). Does someone have any insight regarding the frequency of these issues? Though the app's assets total to about 2-3 MB of pictures, the Flex Profiler has the peak memory at 63MB from the Memory Usage chart. What I am extremely confused about is that the (current) Memory in the Live Objects table totals to about 11,000 (I'm not sure what units (KB?)), which does not match the Current Memory reading on the Memory Usage chart at all. Thanks.

[flexcoders] Re: Amazon S3 + Flex Uploader // help!
Assuming you mean Christian's library for ss3, I've looked at removing AIR dependencies and found a couple of issues: The main thing is that the library uses a File object which will need to be changed to a FileReference. It uses File because is provides uploading via S3's RESTful API, and which flash player doesn't support PUT. S3 does provide an alternate method using POST. So the AS3 library would need to be altered to use POST with FileReference instead. And of course to keep the private key secure, you'll probably need a backend to generate yours authentications.

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.

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

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

relationship between event and handler*/
systemManager.addEventListener(
GetNewsEvent.GET_NEWS_EVENT,

systemManager.addEventListener(

systemManager.addEventListener( NewsDataLoadedEvent.NEWS_LOADED_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?

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 - 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.

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.

//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.

No probs mate, it was pissing me off not know what the problem was, too :)

Ok mate, here's the problem:

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.

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] Data Grid issue
Thanks Alex. Finally I got it . What i did is itemEditBegining event set the dataGridEvent variable in the mxml component. Whenever i goes to the submit button i manually calls the itemEditEvent with an argument that is set with the help of itemEditBegining.This way i restrict the user for entering invalid data while pressing the submit button. I wonder itemEditEnd should fire automatically when user clicks on submit button. Alex Harui [EMAIL PROTECTED] wrote: No, I havent.
