[flexcoders] Refreshing Project
Hi, After more than 4h trying everything I know and researched until page 25 of Google results, I give up and decided to ask here. I wrote a piece of code that was trying to do something like that: AsyncToken(RemoteObjectInstance.AsyncTokenMethodName).send.apply( RemoteObjectInstance, args ); This was crashing inside the send method when it was trying to get remoteObject.concurrency; reporting my the remoteObject == null; So I changed my code a bit to work around it and leave this call (send + unknown number of arguments) to the right place. Compiled and... nothing. It was referencing to my previous code (the one with send.apply). So I started my attempts: turned off build automatically refresh + build refresh + clean + build clean + build clean + refresh + build refresh + build + build clean + build + build delete files from filesystem manually + clean + refresh + build + build turned on build automatically all previous attempts I decided then to reboot my system and try again everything. Nothing. It lasted my attempt to delete the project and import a new one. I did it no success. Reboot? Ok... Deleted project again, rebooted, imported again, compiled and... nothing. Maybe a fresh checkout and merge of patch? Yeah... let's try it and... nothing. Reboot again? Oh my God!... Nothing! Now I'm asking to you HOW CAN I GET THIS REFRESHED??!?!??!?!

[flexcoders] Bindable does not behavior in extended class
Hi,
Here is my daily question.
I have a class that handles Form + HTTPService (a subclass called
Service w/ events complete and fail) automatically called ServiceForm.
Since most code is replicated in extended classes if you are editing
one item (another HTTPService subclass that retrieves it and assign to
an XML Bindable variable), I optimized in a subclass of ServiceForm.
The name of this class is ServiceEditForm.
Here is the code:
package core.containers
{
public class ServiceEditForm extends ServiceForm
{
[Bindable] public var item:XML;
public function ServiceEditForm()
{
super();
}
override public function getParamObject(httpFormat:Boolean =
false):Object
{
var params:Object = super.getParamObject(httpFormat);
params.itemId = item.hasOwnProperty('id') ?
XML(item.id).toString()
: XMLList([EMAIL PROTECTED]).toString();
return params;
}
}
}
And then I have my classes that build EditForms... like
EditCenterForm, for example:
?xml version=1.0 encoding=utf-8?
ServiceEditForm xmlns=core.containers.*
xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:parton_controls=parton.controls.*
url={Environment.getInstance().MODULE_URL}Center/Edit
complete=handleFormComplete(event)
mx:Script
![CDATA[
import core.Environment;
import core.events.DynEvent;
import mx.controls.Alert;
protected function
handleFormComplete(event:DynEvent):void
{
Alert.show(event.result.message.toString(),
Edit Center);
}
]]
/mx:Script
mx:FormItem label=Company: width=600 direction=horizontal
parton_controls:CompanyComboBox id=company width=100%
selectedId={item.hasOwnProperty('company_id') ?
XML(item.company_id).toString() :
XMLList([EMAIL PROTECTED]).toString()}/
/mx:FormItem
mx:FormItem label=Name: width=600
mx:TextInput id=centerName width=100%
text={item.hasOwnProperty('name') ? XML(item.name).toString() :
XMLList([EMAIL PROTECTED]).toString()}/
/mx:FormItem
/ServiceEditForm
Sorry for that much code... but it's quite simple.
When I do this and compile code, I get these errors:

It seems it's an issue regarding the [Bindable] assignment in my
ServiceEditForm class.

Re: [flexcoders] Bindable does not behavior in extended class
Hi this is my hierarchy:
class core.containers.Form extends mx.containers.Form
class core.containers.ServiceForm extends core.containers.Form
class core.containers.ServiceEditForm extends core.containers.ServiceForm
And the last class (that is exploding the issue) is:

Does that help you in something?

Re: [flexcoders] Bindable does not behavior in extended class
I tried 2 different ways, without success.
The first one was:
[Bindable] protected var _item:XML;
public function set item(value:XML):void
{
this._item = value;
}
public function get item():XML
{
return this._item;
}
And the second one was to make the class ServiceEditForm as Bindable.
Both exposed me the same issue.
Another ideas?

That just means your form is an EventDispatcher, I have no idea. :)
It could have something to do with the XML (binding) and a bug.
You might try making the Bindable property and object and test if you get
the same error.
If that doesn't work try using a getter-setter (for the bindable XML) with
bindable and use commitProperties().

Re: [flexcoders] Bindable does not behavior in extended class
Nope...
It didn't work.
BUT I know how to remove the errors, but then my component will not work.
My Form is just and extension of mx Form + new methods
The ServiceForm adds a a component (one core.rpc.Service instance) and
adds all methods that relates the children (FormItems) and Service
request.
Later, my ServiceEditForm adds another core.rpc.Service instance,
which is responsable to retrieve the item to be editted + other handy
methods.
If I remove the core.rpc.Service object of ServiceForm, everything works fine.
Both instances do not have the same ID.
It's weird, because I have a lot of classes that was already extending
the Service Form and worked VERY WELL.
Maybe because all other classes were including only FormItems? And
that's the only place that includes something different?
Any ideas are VERY appreciated.
Thanks in advance,

You need to look at what's different from the files that worked. Check to
see if it's due to your bindable property being named item or being typed
as XML. Change the binding expression to be less complicated perhaps? What
if you wrote a simple function that did the ternary expressions and just
passed in a parameter that doesn't do any e4x drilldown?

[flexcoders] Multiple requests to load module do weird behaviors in app
Hi,
I'm currently working in an extremely big application written in Flex
+ PHP + Oracle.
It's entirely controlled by modules and events dispatching and
listenings to reduce memory overhead.
Each app piece is a module which is loaded when requested to be viewed
and unloaded when closed.
To support this modules dependency, I have this small class that
controls the Module loading in my application:
http://pastebin.com/f73a59279
Static method Environment.getModuleURLFromPackage does something like:
return module.replace( /\./gi, / ) + .swf;
And I implemented a wrapper to DRY module load calls:
public static function loadModule(module:String, handler:Function,
showProgressInfo:Boolean = false):void
{
// Registry to prevent multiple instances of same module
var m:AdvancedModuleLoader = AdvancedModuleLoader.create(module);
m.showProgressInfo = showProgressInfo;
m.addEventListener(ModuleEvent.READY, handler);
m.load();
}
The code to get it working is really simple:
Environment.loadModule(modules.company.dialogs.CreateCompanyWindow,
function (e:ModuleEvent):void
{
// Dialog creation
var dialog:* = e.module.factory.create();
PopUpManager.addPopUp(dialog, Environment.getApplication(), true);
PopUpManager.centerPopUp(dialog);
}, true);
In this example, it opens a module based TitleWindow, but there're a
lot of other situations, like Canvas based Modules, FormItem based,
etc.
What's the issue here?
If I keep calling this execution (for example click a lot of times in
a button), there're different behaviors:
1- It freezes my application
2- It loads the first one and start to open alert messages SWF is not
loadable (one per click)
3- It never finishes to load the module and fails silently
4- It loads the first one (but not the others), but never removes the
progress bar
The most reproduceable ones are numbers 2 and 4.
Can someone please give me any idea how do I fix this?
Thanks in advance,
Best regards,

Re: [flexcoders] Multiple requests to load module do weird behaviors in app
Hi Alex,
I never meant to get a ready to use code, I hate that. We only learn
something by doing things by yourself. I just want ideas, that's what
I asked for.
I don't understand one point and maybe you can highlight me.
In the case I do not have the module loaded and I click twice (for
example), I have 2 requests to me called later (only when module is
ready).
Suppose I decide to stack a method call and the module read event just
instantiate the class and call it each time it was scheduled in pipe.
In this situation, I'll have to instantiate through the class name (ie
var foo:* = new my.ns.ClassFoo();), which schedules module to load it
and the idea of module loading/unloading does not work.
Another idea is to try to avoid the ModuleInfo.load() call.
In this situation, the module ready is never called again, so I'll be
unable to call again. This idea is not acceptable, since I may want to
open 2 tabs for example of the same module (for example... Create
Company tab).
In all situations I've imagined, I still rely on ModuleEvent.READY.
Which means I must have to use the event to be able to not load the
module during compilation (only possible through
e.module.factory.create();).
So, it must call ModuleInfo.load() and also only instantiate instances
through e.module.factory.create().
By adding these restrictions... I cannot imagine any other
implementation except the one I wrote.
What does my idea do?
It only has a single ModuleInfo for each module to be loaded and
attach various READY listeners (once per click) to be called when load
is completed.
Hum maybe looking at source now I can understand my issues.
I always attach my listeners to READY event and at the end of READY
event I dispatch the same event again. Maybe I'm in a recursive loop?
Anyway, I'll try to address that
but if you have any other ideas, please share with me. I do not want
code ready, just the concept behind the code. Leave me to implement
it.
That's how I like to work. =)
Thanks in advance,

PopUpManager.centerPopUp(dialog);
}, true);
In this example, it opens a module based TitleWindow, but there're a
lot of other situations, like Canvas based Modules, FormItem based,
etc.
What's the issue here?
If I keep calling this execution (for example click a lot of times in
a button), there're different behaviors:
1- It freezes my application
2- It loads the first one and start to open alert messages SWF is not
loadable (one per click)
3- It never finishes to load the module and fails silently
4- It loads the first one (but not the others), but never removes the
progress bar
The most reproduceable ones are numbers 2 and 4.
Can someone please give me any idea how do I fix this?
Thanks in advance,
Best regards,

Re: [flexcoders] Multiple requests to load module do weird behaviors in app
Ok.
But how would I instantiate another objects without knowing its name then?
Currently I rely on event.module.factory.create(), which is called on
READY event.
By not calling the load() method, it'll never reach the READY event
again, so I'll be unable to use it.
Hm... maybe storing the Class in the Registry item?

Hi Alex,
I never meant to get a ready to use code, I hate that. We only learn
something by doing things by yourself. I just want ideas, that's what
I asked for.
I don't understand one point and maybe you can highlight me.
In the case I do not have the module loaded and I click twice (for
example), I have 2 requests to me called later (only when module is
ready).
Suppose I decide to stack a method call and the module read event just
instantiate the class and call it each time it was scheduled in pipe.
In this situation, I'll have to instantiate through the class name (ie
var foo:* = new my.ns.ClassFoo();), which schedules module to load it
and the idea of module loading/unloading does not work.
Another idea is to try to avoid the ModuleInfo.load() call.
In this situation, the module ready is never called again, so I'll be
unable to call again. This idea is not acceptable, since I may want to
open 2 tabs for example of the same module (for example... Create
Company tab).
In all situations I've imagined, I still rely on ModuleEvent.READY.
Which means I must have to use the event to be able to not load the
module during compilation (only possible through
e.module.factory.create();).
So, it must call ModuleInfo.load() and also only instantiate instances
through e.module.factory.create().
By adding these restrictions... I cannot imagine any other
implementation except the one I wrote.
What does my idea do?
It only has a single ModuleInfo for each module to be loaded and
attach various READY listeners (once per click) to be called when load
is completed.
Hum maybe looking at source now I can understand my issues.
I always attach my listeners to READY event and at the end of READY
event I dispatch the same event again. Maybe I'm in a recursive loop?
Anyway, I'll try to address that
but if you have any other ideas, please share with me. I do not want
code ready, just the concept behind the code. Leave me to implement
it.
That's how I like to work. =)
Thanks in advance,

Hi,
I'm currently working in an extremely big application written in Flex
+ PHP + Oracle.
It's entirely controlled by modules and events dispatching and
listenings to reduce memory overhead.
Each app piece is a module which is loaded when requested to be viewed
and unloaded when closed.
To support this modules dependency, I have this small class that
controls the Module loading in my application:

Static method Environment.getModuleURLFromPackage does something like:

{
// Registry to prevent multiple instances of same module
var m:AdvancedModuleLoader = AdvancedModuleLoader.create(module);
m.showProgressInfo = showProgressInfo;
m.addEventListener(ModuleEvent.READY, handler);
m.load();

[flexcoders] Reaching subclass constant inside base class (similar to self.CONSTANT)
Hi,
I have this implementation in my base class:
BaseSelector.mxml:
public static var MODULE:String = core.dialogs.BaseDialog;
protected function handleSelectClick(event:MouseEvent):void
{
Environment.loadModule(BaseSelector.MODULE, function
(e:ModuleEvent):void
{
// Dialog creation
var dialog:* = UIComponent(e.module.factory.create());
dialog.multipleSelection = multipleSelection;
assignDialogHandlers(dialog);
PopUpManager.addPopUp(dialog, Environment.getApplication(),
true);
PopUpManager.centerPopUp(dialog);
}, true);
}
As you may see, I have a constant being defined in base class.
Each subclass defines a new MODULE name, and the handleSelectClick
need to be able to load it and instantiate a new Dialog component
(BaseSelector.MODULE).
So imagine I have a CompanySelector.mxml, which extends from BaseSelector.mxml:
public static var MODULE:String = app.dialogs.CompanyDialog;
And nothing else.
The button event listener (handleSelectClick) should be able to
recognize the MODULE defined in subclass and define the subclass one
to be loaded.
I tried it by several ways to achieve the same thing as self in some
known languages, without success.
Has anyone any ideas how to do that?

[flexcoders] Dispatching AdvancedDataGrid change event by hand
Hi all, I'm implementing an automate way to select items by passing the id of rows. The idea is to simple do: root item id=1 / /root this.selectedId = 1; And it'll select the item that has id = 1. I get everything working as expected, except of events triggering. When I do a simple this.selectedIndex = i; If changes the selected row as I want to, but does not trigger the change event. So I need to manually trigger this event (since I have actions related to this event). How to I manually call this event? I did this for a ComboBox, which had the same issue too... I did that by doing: this.dispatchEvent(new ListEvent.CHANGE, false, false, 0, i)); But now the component is AdvancedDataGrid. By answering the first question, I also want to ask about how do I do the same event for multiple rows selection (when allowMultipleSelection = true).

Re: [flexcoders] PHP vs. Coldfusion 8 for beginner?
Pay attention to the way you write your software and you notice what
am I meaning...
Notice to syntax, it's the main reason I said that.
In ColdFusion, to define a variable you do a tag like in HTML: cfset
message=Hello World!
In PHP: $message = (string) Hello World!;
In C#: string message = Hello World!;
In Java: string message = Hello World!;
In C: String message = Hello World!;
In ActionScript: var message::String = Hello World!;
If you want more, just ask =)
Now pay attention... none of them (except CF) needs a tag. PHP is
loosely typed, so it does not need a cast, I added it just to make the
example more similar.
Now, let's go to a better example IF statement:
CF:
cfif message eq Hi
!-- Do stuff --
/cfif
PHP:
if ($message == 'Hi') {
// Do stuff
}
C#:
if (message == 'Hi') {
// Do stuff
}
Java:
if (message == 'Hi') {
// Do stuff
}
C:
if (message == 'Hi') {
// Do stuff
}
Which ones are more similar to the rest... PHP or CF?
Of course there're MANY differences between one language and other...
and if you ask me which one is more similar to Java? C#.
So, I'm not telling PHP is like Java or C# or even C. I'm telling you
that the learn path (syntax has less impacts) is minimized if he
decides to learn PHP instead of CF.

Re: [flexcoders] PHP vs. Coldfusion 8 for beginner?
Talking about implementation similarities, you're true.
PHP has almost nothing related to Java.
As an example, I'll show you how to concatenate an array using a
separator in PHP and Java:
PHP:
$myArray = array(1, 2, 3, 4, 5);
$myString = implode(', ', $myArray);
echo $myString; // prints: 1, 2, 3, 4, 5
Java:
int[] myArray = {1, 2, 3, 4, 5};
String myString = ;
for (int i = 0; i myArray.length; i++) {
if (i!=0) { out += ', '; }
myString += myArray[i].toString();
}
System.out.print(myString); // prints: 1, 2, 3, 4, 5
But as I said... someone that has some knowledg in
structured/object-oriented languages is able to read it and knows
better than CF what's going on.
The similarities are smoother, you're able to read a Java code if you
know PHP, aswell as C# if you know Java... but it's a bit hard to read
a Java code if you only know CF.

and
if (message eq Hi!)
{
// Do stuff
}
Which ones are more similar to the rest... PHP or CF?
Of course there're MANY differences between one language and other...
and if you ask me which one is more similar to Java? C#.
So, I'm not telling PHP is like Java or C# or even C. I'm telling you
that the learn path (syntax has less impacts) is minimized if he
decides to learn PHP instead of CF.
Interesting. My experience has been that the syntax differences are really a
minor part of learning a new language. Certainly the most obvious
difference, but the smallest in terms of real mastery and hurdles to
overcome. Each language has it's own nuances and particular ways of handling
the same concepts. In this way, PHP (and CF) is verrry different than
Java or C.

Your first problem is how much data you are loading into a tree. In

Second problem, IE 7. It's the absolute worst browser on the

Your solution to overcome the issue is as you already found -
don't

Re: [flexcoders] Re: Nested property display in ADG
Hi,
Thanks for the quick answer.
I do not like the tree effect... I want a plain grid first (later I'll
use the tree but based on other things).
++--+
| foo| bar |
++--+
| 1 | test |
++--+
That's what I want... I have around 10 xml nested items and the user
will be able to display all columns if he/she wants to.
So my idea is a nicer solution than labelFunction (which I'd have to
make a switch for all fields).
That's my real structure: http://pastie.org/241033 (each item is the
row I want to display on grid).
Is it better explained now? There must have a nicer solution for this
instead of labelFunction =)
Thanks in advance,

Try this inside your ADG MXML:
mx:dataProvider
mx:HierarchicalData source={yourXML}
childrenField=Bar/
/mx:dataProvider
Then you can use name in your dataField. Note that this will give
you a hierarchical (tree-like) effect.
If that's not what you wanted, you can probably use a labelFunction.

[flexcoders] Covering XML possibilities for automate object building
Hi all, I have an automate script that converts a Form to params in both ways: HTTP or Flex. So, if you want to pick information from Form to be used in the Flex application, you simply do var params:Object = form1.getParamObject(); Also, I optimized it to work ok in HTTPServices, do it becomes enabled to automatically send POST params: service.send(form1.getParamObject(true)); // the argument is httpFormat? (default=false) Maybe there's an easier way to do it without having to define the mx:request params by hand, and I'm interested to listen your solution regarding this. By now, my application has two possible implementations in a ComboBox: item id=1 label=foo/ or item id1/id labelfoo/label /item There's no restriction to this yet. So, my automate script needs to cover both situations. I tried this: var selection:XML = formItem.selectedItem as XML; params[formItem.id] = (httpFormat) ? XMLList(selection.id || [EMAIL PROTECTED]).toString() : selection; Without success. I'm interested to know how to achieve it in a simpler way. Can you help me with this one?

[flexcoders] Re: Covering XML possibilities for automate object building
I fixed myself.
That was easy... I just need another eye to not do stupid questions and things.
Solution:
var selection:XML = formItem.selectedItem as XML;
params[formItem.id] = (httpFormat)
? (selection.hasOwnProperty('id')
? XML(selection.id).toString()
: XMLList([EMAIL PROTECTED]).toString())
: selection;
Thanks anyway!

[flexcoders] Real Multicolumn Form in Flex
Hi all, Does anyone have already implemented a multicolumn form in Flex? Before you point me to Google (GIYF), I already tried all solutions available, including the most known ones: - http://www.adobe.com/cfusion/communityengine/index.cfm?event=showdetailsproductId=2postId=9644 - http://jc.pontaza.com/wp/?p=77 - My own Let me first describe the each ones: Adobe's: It plays really nice, until you need to define an item that occupies more than a single row. There's no colSpan (as in HTML), but there's rowSpan for column. Potanza's: Weird, really weird solution. It only accepts column organization if you use its FormGroup class. Inspecting source, you'll see that FormGroup extends Form, and the entire idea behind a single Form is down. My automate script pick each FormItem (or any other class that I define) and incorporate all children picking its value depending on children class instance. Sounds big and yes, it is. The issue is that this automation ignores other Forms. So if you define a nested form inside the one you're calling, all fields internally defined are ignored. Mine: I used a simple HBox and made Box children inside. It did everything I wanted, except label spacing. The form inputs does not left align to the higher one, and becomes horrible. I switched then to Grid, and the same issue happened again. Now, I ask the same question again does anyone have already implemented a *real* multicolumn form in Flex? If possible could you share the source or swc file?

internet I saw someone telling that missing this might be a problem
(solved the requester' issue), but didn't have any effect for me...
