Re: [flexcoders] Execute click programmatically
use:

I remember using the same approach before, so it should work.

Re: [flexcoders] mxml components
it depends on references, not whether you use or not. so for example, if the code is like this: MainClass.mxml foo:MainClass foo:SubClass id=bl/ /foo:MainClass SubClass.mxml foo:SubClass foo:SubClass2a id='bla'/ /foo:SubClass they will live forever. But if you load them dynamically, it depends on where you keep the reference. If the reference is lost, it 'may' get removed by garbage collector. (can never be sure because by the nature you cannot control garbage collector). So it depends what you mean by call (calling a function or creating) and also the creation policy of the container class. One more thing to pay attention on memory manager is be careful with the event listener. For example When you write: A.addEventListener(fooEvent,B.onFooEvent); a reference from A to B is created, so there is nothing to keep A in the memory. If you pay attention on creation policy and addEventListener, you'll be fine. yigit Scott wrote: Ok, I’m trying to get a firm grasp on AS3 components/classes.

Take the following examples… MainClass.mxml | |subclass1.mxml | |subclass2.mxml | |subclass2a.mxml If MailClass.mxml calls subclass1.mxml, completes and then calls subclass2.mxml which calls subclass2a.mxml, what are the lives of these classes?

[flexcoders] html component, different profile (means of firefox)

How can I achieve this using AIR ? thanks.
[flexcoders] testing JS using AIR
hi all, i work for a web2.0 company. We have a system composed of flex ajax. Flex and javascript talks using the FAbridge and external interface. We want to make a mass stress testing for the system but there is no way to test JSFlex using many firefox windows, and what we want to test JS clients under stress. (basically we use flex for FMS and XMPP+jingle connection gateway, we need to see whether clients are robust when they start to talk many other) One thing came to my mind, since AIR can run JS code, we may try pushing all system inside an AIR application and run there (create the test clients as AIR applications). But since I've never coded JS in AIR, I'm not comfortable whether moving the browser codes will be ok or not. (we also use prototype.js library). Has anyone tried running browser js codes inside AIR's browser ? So may I get some comments about this approach? Is that worth to try? any ideas or help is appreciate. thanks, yigit

[flexcoders] basic IDE developement, need ideas best practices
hi all; I need to develop a small text editor inside a big flex application. call it expression editor. the user can write javascript, xpath and should be able to add variables (variables are taken from Model,so the user does not define variable, just add reference). the code should be colored(or shaped) well and must be easy as possible as it can be because the users are not coders. For example, when the users wants to call a function, he should select from a drop down list, then select the inputs again from comboboxes if possible(but the input can itself also be an expression :S). Or when he needs to write an XPath, i need to show a tree according to the xsd which will be loaded according to the selected function. to good news is expressions are like function based language codes, so no sequential coding; the bad news is there are too many expressions in the application in many places; so this GUI must work as a pop-up one (so need to be litefast) before starting development, i wanted to ask for design ideas and best practices. any help is welcome. thnks -- yigit

you can not create variables referencing from this,
but the good news is you dont have to .
so instead of using
var this[customer + i]:Loader = new Loader();
just use
this[customer + i] = new Loader();
then you can reach it this[customer1] e.g.
for efficiency, dont forget to case it back.
(this['customer2'] as Loader).bla bla...

Re: [flexcoders] Re: How to deep copy an ArrayCollection?
this will work for just one level of depth. i mean, if your item has a reference to another object in the model, you will just clone the item not the object so you will have two items referencing the same object. i had this issue and developed a system for this. All my object can be serialized to xml and deserialized from xml. by the way xml generation process is recursive.(when an item's toXML method is called it also calls it's children' toXML methods) this give 100% copy. it may be seemed a bit hard, you may start with learning XSD (xml schema definition) by the way, i just realized that the same recursive approach can be applied using byteArrays. Stephen Allison wrote On 02/04/2008 01:38 PM: In my application I am using ArrayCollections to store data for series on a line chart. I need to be able to make a deep copy of these ArrayCollections so that I can make changes to the data in the copies without affecting the original data. IIRC you can write the whole lot into a ByteArray, which serialises it as AMF in memory, and then read it back out again. Classes in your array need [RemoteClass] in order to get correctly typed objects back. ie. var ba:ByteArray = new ByteArray(); ba.writeObject(yourData); var newCopy = ba.readObject(); Stephen

information that the other one has. I'd like to keep using the same
script file, but it references a variable that exists in one file that
doesn't exist in the other file, and I need to make sure it exists
before I use it.

Thanks for that - but each buttonbar contains dynamic data, so it's

I guess I could count the data, and then do some calculation on the

Re: [flexcoders] Update viewstack view on each button click
creating the view again and again is not a good solution;
instead you better use data binding and keepdata valid in a singleton
model class...
another (bad) solution is that, if your component do their business job
themselves (connect to server, retrieve data); implement them an init
function which you will call when you select that component. the
function will free the data arrays first then retreive data from server...
but as i said before; you better use a singleton Model class.

Re: [flexcoders] Simple sprite creation not working
the reason is that your main.as does not have a valid view.
try passing the mxml view as an argument to it and call it's addChild
function;
e.g.
public function createSprite2():void{
var main:Main = new Main();
main.createSprite(this);
}
and in main.as
public function createSprite(con:UIComponent) : void{
var visual:Visual = new Visual();
var ref:UIComponent = new UIComponent();
con.addChild(ref);
ref.addChild(visual);
trace('called from Main.as');
}
and it should work...

Re: [flexcoders] function binding toString !! Additional information
http://127.0.0.1:49661/help/index.jsp?topic=/com.adobe.flexbuilder.help/html/databinding_4.html
here; in the first example, there is a bindable function and it is not a
setter or getter.
so functions other then setters and getters can be binded!
so my question should have an answer...
by the way, i'm dont have to use function biding, i can make thinks work
without it, but when i saw it
i decided to use, cuz it is cool :) , and good in terms of code
readiblity...
so , check out te following example, an event triggers the binding of
the function and the function(is Enabled) is neither a getter
or a setter:
?xml version=1.0?
!-- binding/ASFunction.mxml --
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Script

}
private var _myFlag:Boolean = false;
// Define a setter method that dispatches the

public function set myFlag(value:Boolean):void {
_myFlag = value;
dispatchEvent(new Event(myFlagChanged));
}
public function get myFlag():Boolean {

I believe you can only bind vars and setters. By binding a function i
think it will only execute the function once. An easy workaround
is to
have a var containg the result of the toString function and bind the
property to that var. Something like:
[Bindable] public var stringValue:String = ;
public function toString():String {
stringValue= this.toString();
return stringValue;
}
mx:Label id=lbl text={data.nameID.stringValue}/

Yes, indeed there was a circular reference to toString. Thanks for the
correction. The general concept is the same though, and I think it's the
best way to solve the bind to function problem.

[flexcoders] how does import statement,work? a possible fb bug
hi all; in my cairngrom application, i have many classes and some of them has the same name but of course diffrent packages. i autogenerate code, so to not to let ambiguity, i alway use classes with their packages. e.g. instead of writing var foo:Foo; i write var foo:tr.com.sth.vo.Foo; the compiler give and interesting error, saying that con not recognize tr (my initial package name); but when i go to the end of tr.com.sth.vo.Foo and press ctrl+space after waiting seconds, and rebuilt; the error goes!

Re: [flexcoders] Loading combobox problem...
i just can not give a solution to your first question cuz i couldn't

anyway;
here is a better way to handle shared data; a MODEL .
model is a singleton class that generally keeps shared data of your
applicaiton.
it should look like ; and you MUST alway call getInstance() to reach it...
like , Model.getInstance().arrayCollection
public class Model{
private static var instance:Model ;
public var arrayCollection:ArrayCollection();
public var foo:Foo; //etc etc ...
public static function getInstance(){
if(instance == null )
instance = new Model();
return instance;
}
public function Model(){
if(instance != null); //ERROR!!!
}
}
by the way; i wrote it here; there may be a syntax error ...
wish it helps...

The following is in flexbuilder 2, AS 3.
I have an application that I am building with modules using
NetConnection to access the server. I want to centralize the routines
that get data from the DB for Combo Boxes and the like because I want
to reuse the data returned.
In the parentApplication, I created my function to query and handle
the result, storing the data in a public arrayCollection. In the
module, I access the data by setting the dataprovider to
parentApplication.myArrayCollection. Due to the asynchronous nature
of Flex the data does not appear the first time the module displays
but does if I redisplay the module.
My solution which does not work was to do;
parentApplication.myArrayCollection.addEventListener
(CollectionEvent.COLLECTION_CHANGE,LoadLists);
where LoadLists is a function that sets the dataprovider for the
combobox. LoadLists never gets executed. Being the resourceful
individual I decided to try to force the event by inserting the
following line in my result handler in the parentApplication;
myArrayCollection.dispatchEvent(new CollectionEvent
(mx.events.CollectionEvent.COLLECTION_CHANGE));
This still does not force the event to occur.
Is this a bug, or what am I doing wrong?
A secondary question is;
What is the best way to handle static (mostly) data for combo boxes
so that;
a) It is queried only when needed and
b) Stored at the client for the current session to reduce DB hits?

[flexcoders] cairngorm design question, need suggestions
hi all; i work in a project which includes the implementation of a RIA application in which the user will generate an XML based on an XSD defined language using dragdrops and etc. (user never sees the xml). at first, we developed a code generator using AIR that takes the XSD and generates vo's, commaders, events,model controller. so we just hand coded the views. and the demo was very successful. now the second phase of the project came and there are huge differences in the XSD, so we had to handcode additional things into commanders, which violated the auto-generation approach and resulted in some bugs inefficiency. then we decided to upgrade the code generator to create more clever commanders and more specific events. we have an important debate here for which we need suggestions, so i'm presenting you our question. when an event is being handled, there may be need to do some more things which is done by another commander and has a specific event. in such a situation, -- should the commander call the other commander just creating the event and sending it to the other's execute method or --should the commander create the event and just dispatch. the second is the normal way for the cairngorm specs but the first is much more efficient. so which one do you suggest? thnks. p.s. commanders are specific to VO's a a commander just edit's it's VO's data on the model.
[flexcoders] cairngorm design question , need suggestions
hi all; we have a GUI built with flex using cairngorm microarchitechture. the GUI is quite complex, and there is an xml schema (xsd) that represents the VO structure. We prepared a code generator(using AIR) which parses the xsd and creates vo's,commanders,events,modelfrontcontroller, so we just handcode the view. (Vo's are serializable to XML and deserializable from XML , all auto generated -sth like jaxb of java- ) the GUI was good for version1 but the XSD had to change a lot and we had to insert hand written code into commaders and we started to have performance issues. now there is a new XSD, GUI will be recreated and we want to upgrade our code generator to support the changes (more clever commanders more specific events!); so here comes my design question : every class has it's own commander. and sometimes, when an event is being executed, another commander should also work(sth more must be done), and there is a specific event for that operation too. (e.g. deletion of an instance of class A requires the update of the instances of class B ) in this situation, 1 should commanderA dispatch an event to update class B instance or 2 should commanderA call commanderB's execute function with the needed event as argument or 3 should commarderA edit B vo's . (we don't prefer this cuz it violates the generic style of our code cairngorm) the second option is more efficient since it does not need to dispatch the event and wait for it to be caught; but we wonder whether it violates the cairngorm design pattern rules. this is a really important project, so we'll be very pleased by taking your comments.
