Flex :: Life Cycle Used By Flex Application?
Dec 14, 2009
Driven on by curiosity, I'm trying to understand the Life Cycle used by Flex Application. I've done a little research on this argument; the two key concepts used into the FlashPlayer are:
SWF Frame: it's the logical unit that contains graphical code and as code Flash Player Frame: it's the time interval used by Flash runtime to update the screen and defined by frameRate property
If so, could you explain me the relationship bewteen these two concepts? In particular, are they paired togheter or not? The main rule is: the Flash Player streams in a swf; until a full SWF Frame is read, the Flash Player cannot render it.
I'll try to explain what I need to understand. For the sake of simplicity, suppose you have a two frame application: SWF FR 1 and SWF FR 2.
In general (for example in CS4) a frame is considered as a logical unit (delimited by ShowFrame tag) where you can attach as3 code. This as a simplified version of a swf file, i think:
Header // frameRate is defined here
Symbols, classes etc... // this is FR1
=== ShowFrame ===
Symbols, classes etc... // this is FR2
If you have two frame, FR1 and FR2, Flash starts executing FR1 and goes to the next one (FR2). If you don't stop the excution, the Player executes and renderes code contained into FR1 and FR2 through an infinite loop. On the contrary, when you stop the execution, for example in FR2, the flash player loops executing code contained in FR2.

Nice to be back to this forum again. I need to know if instances of the movieclip, that is "classically tweened" are reused between keyframes, or are they recreated (reinstantiated). Thus may I rely on the fact, that only the properties of one single instance change during the classic tween, or are new instances created on entering keyframes?
My little experiments on that show that the bad variant is happening (instances are recreated), but maybe I misunderstand or misuse something? here is the link to the file which made me doubt (CS4). In the last frame of the animation all previously saved references to the instance are saved abnd compared in pairs. Not all of them are equal and sometimes event some are null.[URL]...

For some reason I can't seem to match a parentheses in Flex using Regex to save my life. What's wrong with this?
var commandTxt:String = "switchview(adf)";
var switchViewArray:Array = commandTxt.match(new RegExp("switchview(", "i"));
I've tried dozens of things, but I can't seem to get a match the parentheses. What's the catch here?

I'm trying to cycle between 2 different tween actions in Flex. Here is what I'm trying so far: In declarations:

The problem is that once I start the animation (by clicking a button), I get a timeout error saying the script has been running for longer than 15 seconds, with no tweening ever occurring. The animation works if I were simply animating it once.

I am trying to access html files protected by basic authentication. Below is the code to do that but I still get the authentication dialog. I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog.
Is there a way to add authorization header to the subsequent requests as well?

I am working on an Adobe AIR (2.0) application that contains a feature to allow users to print documents (such as salary slips). Those documents are originally in PDF format. Due to circumstances we cannot directly display those PDFs in the AIR application (for example using flash.html.HTMLLoader). Therefore we convert the PDFs to SWFs (using the pdf2swf tool, see The SWFs are loaded into the application using a mx.controls.SWFLoader, like so:
<mx:SWFLoader
id="salarySlipImage"
loaderContext="{someLoaderContext}"

I'm just learning about Flex and I'm loving it. Unfortunatly I still have to make the decision on which RIA technology to use and its dependent on, among other things, from the following case: How can we wrap a java applet around a Flex application? More specifically, I would like to wrap/integrate NASA's World Wind applet in a Flex panel, similar to what Adrew Trice did with the Google Earth API.
An alternative would be id Flex would support direct access to the 3D hardware through OpenGL or DirectX. But I do not think that that is the case yet, not even through AIR.

I have a Flex 4.6 web game which displays 2 Lists with virtual layouts with 2 custom item renderers. The renderers consist mainly of BitmapImages displaying user avatars + few Labels.
The Lists are being updated often over TCP socket with gzipped JSON data. I merge that data into 2 ArrayCollections serving as dataProviders for the Lists. This seems to work well, the Lists do not flicker and are updated correctly (I've monitored debug traces a lot to get it right).

I have a quite different problem with resizing. I have a Flexbook component which uses the middle part of screen (center) with a html header menu and footer. The problem: The scaling works perfectly when we run in the local machine ( Flexbuilder). But when we deploy it to the server its like scaling never existed.. The requirement: when user maximizes the window or minimizes it, the Flexbook should be resized to fit the screen.

I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.

Is there a way to tell at runtime if a flex UIComponent is in the user's view or not.For example, if I have a tabNavigator with a combobox on each tab, is there a property of the comboBox that will tell me if it is visible to the user or not when I switch from one tab to another?I know it is not the comboBox.visible property. That is set to "true" for both comboboxes. I want a property that will change when I switch from one tab to another making the comboBox visible to the user. I don't know what that property is.

i have a mobile application that i am attempting to use to load an interactive .swf file. At first, i was just going to use the .mxml applications from my other project file in flex, but they're for desktop apps and running on Flex 3.6, and Mobile apps can't be built on less than 4.5 :P
so, i figured i'd export the first project to a .swf, and load it in my mobile application, but nothing i do will get it to show up. anyone know a solution?

I have a Flash Builder application which uses URLs within its code and I want to be able to change these URL values without having to recompile my application, i.e. I want to have a plain text file I can edit which is used to populate these URL values when the application begins. I've worked out what feels like a kludge to do this with ResourceBundles, but maybe there's a better or more straightforward way to go about this.

I'm trying to develop a simple mxml Flex application to start Skype from the AIR/Flashplayer runtime. Is it possible to get back events from a native Windows application? In the simple example of Skype, the OS returns control to the Flex app when Skype exits. But what about native applications which have their own event model and wants to communicate with the Flex event model. For example, a Face detection system which shows "Hello" on a Flex app when the camera detects a face. Can this be done in the current Flex framework?
