No simple example handy, but it is straightforward.
Declare a Class, implement public properties using either public variables

I suggest that in your serviceResultHandle r you do something like:
var oTemp:Object
var xl:XMLList = _xmlData.children( );
For ( var i:int=0;xl.length( );i++) {
oTemp = { SupplierID:xl[ i].SupplierId. text(), CompanyName:
xl[i].CompanyName. text(), . }
arrDP.addItem( oTemp);
}
Still better would be to create a VO with strongly typed properties(Supplier

[flexcoders] High CPU usage redux
A couple of days ago, I posted a message regarding extremely high CPU usage in an application I was building. Eventually, I concluded that the problem was not the Flex app, but some other processes on the same machine. However, I have since found out that I was incorrect -- the problem was the Flex app after all. So for anyone who read the original post and wondered what might be happening -- in particular, Rick Fotis, who attempted to help -- here's what was going on: The issue was caused by the combination of a creationPolicy setting and the use of a set of skins called iCandy, from the ScaleNine site. Now -- I'm not criticizing the developer of the skins. I don't know enough about what really went on. But I do know this: I had set the creationPolicy on a TabNavigator to all. When I removed this, the CPU usage dropped markedly. But when I went into one of the tabs, the usage picked back up, although not as much. I removed the reference to the skin stylesheet. The CPU usage did what it was supposed to do: spike occasionally, then drop to nothing. So I can only conclude that the skins were causing continual redraws in the background. I've found some blog posts from the folks at EffectiveUI discussing performance problems with stateful skins, so I'm not the only one who's encountered it. Here's one of the posts: http://patrickhansen.com/blog/index.php/2009/03/05/flex-stateful-skins-vs-stateless . Moral is: be careful of stateless skins, even though they seem to be recommended by Adobe. The use of a large number of skinned components (checkboxes, text inputs, etc.) can evidently be a problem -- and I didn't even have that many. I don't know enough to make a technical analysis of the issue; but I hope this may save someone else a few hours (or in my case, days) of pain. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560

Re: [flexcoders] High CPU usage redux
Tom, Just a few quick points... you might already know but would be wise to cover for sake of maintaining history. Resources are allocated as components/controls/whatnot come into view. Your observation that your application footprint increased when touching creationPolicy is what one should expect. The best rule of thumb is to show what you need... need what you show and wait as long as you possibly can before showing anything. With regard to skining. Using a skin in your application will, by its nature, cause the application footprint to increase. Here footprint¹ being memory consumption and not necessarily cpu usage. So, an increased footprint when adding skins into the mix is also something you will probably see. The part that has me scratching my head is that you are seeing high cpu usage - which is something that is typically linked to refresh/redraw rates. How many frame per second are you running at? Have you tried the right click - show redraw regions? If the whole app has a red box around it... That is a good indicator that you are hitting the displaylist / refresh too hard. Do you have any source we can take a look at?

[flexcoders] Re: Value Objects
Just realized I replied with the wrong subject line. Here is my reply: Tim Rowe wrote: The use of 'VO's in Flex has always confused me, largely because as everyone I've spoken to has explained it, all a 'Value' object is is just a Model object - therefore WTF are they being referred to as 'VO's when 'Object' (or Model object) would suffice. Tim, I have always thought of a model and a VO or DTO differently. I think this is a good quick explanation: http://en.wikipedia.org/wiki/Data_Transfer_Object From an MVC perspective, I think a model class contains information sure, but it can and often does contain methods to run logic on data, to retrieve data, to broadcast that data is ready or changed, etc. A Value Object (VO) or Data Transfer Object (DTO) (two terms for the same thing, I usually call them VOs because you don't always transfer them per se) are simple classes that only contain properties that can be get and/or set.

You could use an XMLListCollection :

arrDP = new XMLListCollection( _xmlData );

Hi FlexCoders,
I am able to retrieve an XML data from a backend (ASP.NET) webservice and
simultaneously, bind it to my datagrid.
I want to convert the XML data to an ArrayCollection and bind that Array
Collection to the datagrid instead of the XML data.
The conversion needs to be done so that I could implement a search/filter
functionality for my datagrid.
Here's some of the codes I have:
?xml version=1.0 encoding=utf-8?

Re: [flexcoders] Re: Invoke RemoteObject synchronic
That can't be done. You need to add a result handler to
service.getData method and do your data manipulation in that method
with the result of the remote object call.

Re: [flexcoders] High CPU usage redux
Rick, On Thu, May 28, 2009 at 9:54 AM, Rick Winscot rick.wins...@zyche.comwrote: Your observation that your application footprint increased when touching creationPolicy is what one should expect. Actually, I wasn't very clear: it wasn't that the application footprint increased (though it did, minimally); rather it was that by having a TabNavigator with a creationPolicy of all (which I have now managed to work around), five components were created immediately, each of which added to the CPU load because of the skinning issue that was common to all of them. an increased footprint when adding skins into the mix is also something you will probably see. Sure. But this is CPU usage caused by the stateful skins. The part that has me scratching my head is that you are seeing high cpu usage - which is something that is typically linked to refresh/redraw rates. Do you have any source we can take a look at? The source wouldn't help you, Rick. It's very typical forms-in-a-tab navigator stuff. Yes, the issue must be redrawing -- pretty constant redrawing I'd say. If you look at the blog post I referenced, you'll get a better view of the problem. Effective UI did a good deal of testing when they ran into the same issue, and concluded that it had to be a result of the use of stateful skins -- although they didn't seem to be able to determine the underlying cause. They documented some pretty impressive CPU usage by simply adding more skinned elements. I'm just kinda surprised more people haven't run into it. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560
[flexcoders] adobe autocomplete
Quick question for anyone using the Adobe autocomplete flex component in Flex 3. I have it bound to an array of custom objects. Works great. Have a custom filter function and a label function and it works beautifullly, except that when an item in the resultant filtered dataset has a width longer than the width of the autocomplete component, the cursor highlights the text and scrolls the selected label in the textinput pieve of the autocomp0lete all the way to the right, so the first portion of the lable of the selected item is cut off and hidden to the left. Anyone know how to change this or gain access to the text input portion of the autocomplete component to manipultae the selection of the text?

I think you have the idea of databinding a little backwards. Basically, the
bound variable ('userName' in your example) is used to bring data *in*.
In other words, when you have an element like:
mx:TextInput x=46 y=42 id=myName_ti text={userName}/
... you're saying, I have a variable called 'userName,' and I want the
contents of that variable to be displayed in my text input.
So, for instance, if this text input were in an edit form, 'userName' might
represent data coming from a database, which is being placed in the form for
possible editing.
It doesn't mean that whatever is placed in the text input will be injected
into the 'userName' variable. Again, let's say you're pulling a user's
record from a database for editing, and placed the user's data into bound
variables -- one of which is 'userName.'
So the text input would display the current, existing value of 'userName.'
But if you then want to use the edited value, you have to pull it out.
Because what is typed into the text input is accessed through a different
variable -- in this case, 'myName_ti.text' -- not 'userName.' The latter is
simply what came in, not what's going out.
Now if you wanted to have a different MXML element bound to the value of the
text input, you could.
mx:Button label={myName_ti.text} /
... and whatever is typed into the text input will appear on the button.
But if you want to place the text content back into your 'userName'
variable, you'll need to put it there through an event.
You could use an onchange event in the text input to fire a function that
would place the myName.text into userName. But if you did that, you'd create
a circular binding which probably wouldn't be good.
Assuming this is a standard form-like application, you might have a Save
button with a click event. In the click handler function, you'd validate the
form input and place the contents of the form fields into a value object, or
various variables, then pass those to whatever service actually saves stuff
to the database.

because, i need the result in the same method:
example,

var data:Object = invoke remote Object sync;
/*working with data variable */
data.set .;
data.get .;

form input and place the contents of the form fields into a value object, or
various variables, then pass those to whatever service actually saves stuff

Re: [flexcoders] Re: Successive Videos Display
Flash may be single threaded in terms of ActionScript code execution, but when you call something to load, Flash doesn't stay locked down on the load, it continues to give a slice of its processing to multiple operations, one at a time, stepping through a list of active processes. It even idles for a few milliseconds and then begins the entire process over again, executing code in each movieclip, main timeline, load processes, drawing the screen, breathe and repeat (not necessarily in that order). All net operations are handled asynchronously, you start it and either check back later if its done or listen for an event. So in theory if you had multiple NetStream instances, you could begin loading a video in each one, then attach the stream to the Video instance when you want to actually view it. I wouldn't necessarily attempt to do to many simultaneously, but if you are doing progressive flv you could monitor when the first one has finished loading (not playing) and begin loading the next video assuming you can anticipate the play order. I haven't done this myself, but in theory its plausible and perhaps the only way to do what you want to do. Sincerely Mark R.

[flexcoders] Re: data binding in textinput ?
You could use an onchange event in the text input to fire a function
that
would place the myName.text into userName. But if you did that, you'd
create
a circular binding which probably wouldn't be good.
It wouldn't be an infinite loop; so its not all that bad.

How do I get databinding to work in textinput?
I think you have the idea of databinding a little backwards.
Basically, the
bound variable ('userName' in your example) is used to bring data
*in*.
In other words, when you have an element like:
mx:TextInput x=46 y=42 id=myName_ti text={userName}/
... you're saying, I have a variable called 'userName,' and I want
the
contents of that variable to be displayed in my text input.
So, for instance, if this text input were in an edit form,
'userName' might
represent data coming from a database, which is being placed in the
form for
possible editing.
It doesn't mean that whatever is placed in the text input will be
injected
into the 'userName' variable. Again, let's say you're pulling a
user's
record from a database for editing, and placed the user's data into
bound
variables -- one of which is 'userName.'
So the text input would display the current, existing value of
'userName.'
But if you then want to use the edited value, you have to pull it
out.
Because what is typed into the text input is accessed through a
different
variable -- in this case, 'myName_ti.text' -- not 'userName.' The
latter is
simply what came in, not what's going out.
Now if you wanted to have a different MXML element bound to the
value of the
text input, you could.
mx:Button label={myName_ti.text} /
... and whatever is typed into the text input will appear on the
button.
But if you want to place the text content back into your 'userName'
variable, you'll need to put it there through an event.
You could use an onchange event in the text input to fire a function
that
would place the myName.text into userName. But if you did that,
you'd create
a circular binding which probably wouldn't be good.
Assuming this is a standard form-like application, you might have a

[flexcoders] Re: Value Objects
Ironically upon reluctantly plunging back online today in a quest for VO understanding I came across this post: http://www.advantexllc.com/blog/post.cfm/how-oo-almost-destroyed-my-business Now let me first SHOUT a sincere thankyou to all community members who contribute their expertise to these forums. Second I want to stress my frustration is similar to the above poster in the requirement to learn so extensively at the expense of getting things done. That said, even my limited experience in HTML revealed the need of big apps such as the one I am attempting to have an architecture. So, rather than continuing to understand VOs as a building block toward implementing an architecture I've decided to tepidly take on one of Cairngorm/MVC/Swiz -- actually Mate is the leader after the first hour of reading fwiw. Yet (in no small part because the decision above could be a blind alley) I would appreciate continued feedback on a few conclusions I set out below (hopefully) for the benefit of future readers. 1.) MVC needs to be understood in the context that all three building blocks of a web app (Database -- WebServer/CF -- Frontend/Flex) might each contain some of all three MVC aspects (ie model exists both on View and obviously at dbase). Hence for example a CF architecture like cfonwheels is potentially both supplementary to and redundant to a flex architecture. Similar assertions apply to my intention to push (some) business logic past from CF into MySql Stored Procedures. For better or worse though, many existing architectures focus solely on their layer (DB/WebServer/View). 2.) Implementing any architecture infers learning and then working with a great deal of other peoples sometimes poorly documented code. Yet this to an extent is not that different from using say MXML -- which I probably am semantically wrong to say but is arguably an architecture itself. Regardless, architectures add overhead to non-large apps (presumably there is an economy of scale effect). 3.) Boiling everything down, the need is to manage DBase -- View interactions. JSP/CF can assign properties to DB elements which Flex/AS can map to for increased efficiencies. Cost/Benefit of CF included, are JSP a more programmically straightforward option?? As always, thanks in advance.

You can call load() on one instance (or many instances) while the first one is playing. ActionScript is a programming language, and it has no native support for threads (it has no native support for events either). The Flash Player is the runtime. It has support for events, obviously, through the events API. The player is able to perform a number of asynchronous tasks in the background while the application continues to function normally. Typically for such tasks you'll get progress and complete events. You don't have to do any multi-threading for such tasks yourself: just start the task (by calling the load() method on VideoDisplay for instance) and wait for the events. Internally the player may be using multiple threads or just a single thread for these background tasks. It doesn't matter either way. If it uses a single thread, it'll just loop through these tasks in what can be called the event loop and perform them little by little on each iteration, at the same time processing user events as well. So you continue to get your mouse and keyboard events while the data is still downloading. Manish

It's not the popups that's the problem, it's the fact that you're not listening for the event on the popup object itself. If you did this: popup.addEventListener(...) ... it would work, without bubbles set to true. Manish

JSP/CF can assign properties to DB elements which Flex/AS can map to for increased efficiencies. Cost/Benefit of CF included, are JSP a more programmically straightforward option?? Being relatively new to Flex, I'm probably not qualified to answer this question, but in my (admittedly limited) experience, I've found CF to be the more straightforward approach, albeit the more expensive one, when compared to JSP. FlexBuilder just makes it so easy (especially with the CFEclipse add-on) to work with your CF server-side stuff at the same time you're coding in Flex. And the CF-wizards that are included with FlexBuilder are so easy to use -- only a few clicks to create the CF VO to go with your Action-Script VO, with minimal changes needed in the wizard-generated CF code to make it work. I just find woking with CF to be a ton easier than working with JSP, I guess is what I'm trying to say. FlexBuilder was created by Adobe, so they're probably biased towards CF, which is probably why working with CF within FlexBuilder is easier out-of-the-box. But it works well for me.

[flexcoders] best practice to handle overloading in AS3?
Hi, I am trying to overload a method (same name and different signatures)in a subclass. In the inherited class, the method looks like this: public function set dataProvider(value:Array):void In my subclass I want the method to look like this: public function set dataProviderr(v:Object):void So that I can handle different types. I understand AS3 doesn't support overloading. What would be the smart way(s) to handle this? Thanks. geng
Re: [flexcoders] best practice to handle overloading in AS3?
If you want the same method name in a subclass, we are talking about override, not overload. Flex 'deals with overload' making the arguments optionals, example: public function test(obj:Object = null):void then you can invoke it using test() or test(object). Appears that you are trying to override parent's function but changing it signature, that is not possible. If you want to have in the same class, in the same function, receive two different parameters, you can: public function set dataProviderr(v:Object = null, a:Array = null):void Then you can put the argument that you want, leaving the another one as null or you can public function set dataProviderr(v:*):void This way you can pass anything you like. Both solutions are ugly, IMHO, but is the way flex works.

Hi Pedro, Thanks for the guide. What if I don't have any control over my superclass, like if I were importing this from a swc library or something?

Re: [flexcoders] High CPU usage redux
Tom, After a little more poking around I found this issue in the Adobe bug-base for the Flash Player. http://bugs.adobe.com/jira/browse/FP-1149 ...and... https://bugs.adobe.com/jira/browse/FP-2009 It looks like the root cause isn¹t with skinning but rather frame rate handling which could be triggered in many different ways; one of them being stateful skins. Nice. I downloaded the example at Effective UI for reference and witnessed the problem first hand. I was able to get it to behave (kind of) using a technique outlined by the masterful Grant Skinner. http://www.gskinner.com/blog/archives/2009/05/idle_cpu_usage.html The problem is that while the application has focus cpu usage will be higher... So, I guess the real question is if cpu consumption while the application is active is justifiable / manageable.

Actually, I wasn't very clear: it wasn't that the application footprint increased (though it did, minimally); rather it was that by having a TabNavigator with a creationPolicy of all (which I have now managed to work around), five components were created immediately, each of which added to the CPU load because of the skinning issue that was common to all of them. an increased footprint when adding skins into the mix is also something you will probably see. Sure. But this is CPU usage caused by the stateful skins. The part that has me scratching my head is that you are seeing high cpu usage - which is something that is typically linked to refresh/redraw rates. Do you have any source we can take a look at? The source wouldn't help you, Rick. It's very typical forms-in-a-tab navigator stuff. Yes, the issue must be redrawing -- pretty constant redrawing I'd say. If you look at the blog post I referenced, you'll get a better view of the problem. Effective UI did a good deal of testing when they ran into the same issue, and concluded that it had to be a result of the use of stateful skins -- although they didn't seem to be able to determine the underlying cause. They documented some pretty impressive CPU usage by simply adding more skinned elements. I'm just kinda surprised more people haven't run into it.

The problem is that while the application has focus cpu usage will be higher... So, I guess the real question is if cpu consumption while the application is active is justifiable / manageable. In my case, the answer is no, since I was looking at 80% CPU usage at one point.

[flexcoders] ADG/DataGrid prevent render even from firing immediately on propertyChange
Hi, Is there any way to tell the ADG to not re-render itself immediately after a propertyChanged even has been fired in the dataProvider? I have quite a wide row (lots of cells) and lots of custom logic that updates these dependent properties on each row. i.e. calculated columns. I am doing the calculations at dataProvider level vs labelFunctions. On each set function of one of my cells in the row I raise a propertyChanged event if the value was changed. Tracing through what the ADG is doing I'm finding that its re-rendering each time I raise this event even if its in the same row. Is there any way to tell the ADG to wait a few milliseconds in case another propertyChanged event comes in so as to render once instead of 10 times? If there is no ADG option what is the best pattern for this assuming I want to do this in my underlying dataprovider objects. Should I raise custom events and fake a itemUpdated once I know there are no more changes? I don't see a clean way to do this however since I never really know when I'm done, and using a timer or something of this nature seems like a major hack. -Tom
[flexcoders] Re: ADG/DataGrid prevent render even from firing immediately on propertyChange
You might try enableAutoUpdate and disableAutoUpdate on ICollectionView, not sure if that has the desired affect or not. You could also put custom events in your model objects and manually dispatch collection events or call explicitly tell the grid when to update. --- In flexcoders@yahoogroups.com, tntomek tnto...@... wrote: Hi, Is there any way to tell the ADG to not re-render itself immediately after a propertyChanged even has been fired in the dataProvider?

[flexcoders] Compiling via Command Line
I have created a Custom MXML named PopupInfo.mxml component which is based from a TitleWindow. Am using the MXMLC compiler to compile my App.mxml into a SWF file and embed the same to my asp.net page. The App.mxml file calls the PopupInfo.mxml to display a Popup and I am calling it from App.mxml via the following code: import mx.managers.PopUpManager; var winPopUpInfo:PopUpInfo = PopUpManager.createPopUp(this, PopUpInfo, true) as PopUpInfo; PopUpManager.centerPopUp(winPopUpInfo); How then do I compile the App.mxml altogether with the PopUpInfo.mxml using the command line compiler? Currently, when I compile App.mxml, I only issue the following in the DOS Command Line prompt: C:\Flex_SDK_3\Bin\mxmlc App.mxml and the resulting App.swf file, is the one which I embed to my web page. How can I ensure then that the PopUpInfom.mxml is also compiled using the command line compiler? Thanks
