Flex :: When Does Lazy Loading Become A Problem In RIAs?
Jun 5, 2009
So I've got a simple web application using Spring MVC + Hibernate and am using the OpenSessionInViewFilter. I've recently been thinking of replacing the UI with something like Flex or GWT.At first I thought it would be easy, in that I can just hit my service layer from the new front end. But as I consider this a bit more, I'm a little bit nervous about the issues surrounding lazy loading. Using a traditional web front end it's no problem because I'm using open session in view...everything that needs to get loaded for the view gets loaded as the view is constructed.
So Let's say I've got a method to return a Customer, and a Customer has a bunch of Contacts, and Contacts have a bunch of Addresses, and so on. If I call getCustomer() from my new "RIA" controller, it's going to get a Customer, but the Customer's collection of Contacts is just going to be a proxy or null.

The project I'm working on has a massive background image (800px wide by 2585px tall) that slowly scrolls upwards. Before, I was using the code [URL].. I modified the code to scroll upwards, but in addition to having a weird intermittent bug that occasionally displays a pixel-tall blank line after the image and before looping the next, it really doesn't seem to handle dynamic loading well (I've tried using several different preloader scripts and it breaks all of them), something that may not have been an issue with the initial implementation but is now that I'm using a monstrously huge image.
Thus, my question: a. Is there another bit of free, Flash-based infinite scroll code floating around that has support for lazy-loading background objects (Say, the existing background chopped in 6)?

I am converting all embed statements in my site with lazy loading. The code which was previously like this:
[Embed(source="/newswf.swf", symbol="kungfu")]
public static var Kungfu:Class;
has now been converted to this form:
private var _loader:Loader = new Loader();
public static var abcd:Class = null;
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onLoadComplete);

I am working on a feature for an application that requires Flex 4 functionality. Due to some migration issues of the application from Flex 3.5 to 4.0, I have decided to implement this feature as a module that is compiled with Flex 4.0. The theory is that the application would remain compiled in Flex 3.5 and load the module when it needs it.[code]

If I have rolled my own RSL, and I want to use it in my pure as3 apps, is there documentation or an example of how to do this?
Or do I need to traverse the flex source code to figure out what adobe's engineers have done?

Whenever I download the source code from an internet location, and import that into my Flex workspace, I always get "unable to load xyz.swc" error. Where xyz is any swc file being used in that project.
E.g. I have got the source code (by right click -> View Source) of this cool custom component
[URL]
But I get lots of error of different swc not loading. Though all the swc files are present in libs folder of the project!

I'm working though the Adobe "Flex in a Week" video training series, and I've reached Exercise 9, which deals with creating a remote service call. Up til this point, the data source and images have been local assets (located in src/assets in my Flash Builder project).
I access the room list by this:
<mx:HTTPService id="rooms" url="assets/roomList.xml"
fault="httpFaultHandler(event)"
result="httpResultHandler(event)"/>
Here are the two result handlers:
private function httpFaultHandler(event:FaultEvent):void{
Alert.show("There was a problem","Error");
}[code]...........
However, when I run the application in the blazeDS container, I get no rooms despite the fact that the room list clearly exists in the deployment directory after running the application:
$ find . -name roomList.xml
./tomcat/webapps/odt/adobeODT-debug/assets/roomList.xml
How can I debug the reason for this failure? The deployment process used by the Flash Builder tool is fairly opaque, and the tomcat instance isn't advertising 404s from Flex apps. Is there logging somewhere, or something, that needs to be turned on?

I know there are a lot of questions that have been asked about synchronicity in Flex, but I'm not sure if any cover the same issue I'm having. The title only refers to one possible solution I've been going for with this, but essentially here's my situation:
Say I have a Flex application, and I have an XML file with configuration settings I want loaded into that application, preferably at run-time (Although I would've been fine with compile-time as well but can't find a way to do this as the "-define" command-line parameter will only instantiate strings, numbers, and Booleans and I have some more complex configuration structures - I also cannot merely create these as a bunch of constants in Flex because they are used in numerous other places).
However, some of these configuration settings are also used in the various children of the application when they load, so there's no way to perform and complete the load before these containers are loaded (Because of asynchronicity - these children are loaded while the configuration is still being loaded in and parsed using an event listener and handler; of course, before the handler completes, the children components are already loaded incorrectly).
Is there any way to get this configuration file to load before the application's children do? Or even before the application itself? This approach of synchronizing the application load is only one possible approach, but no other approaches seem to fare any better.

I'm working with modules and each of it will be compiled (deployed) in a common folder in a webproject. In the main class I defined an array of module paths which I need for loading all these defined modules.
How can I make that more dynamically, for instance, I want to say, load all modules in a certain folder an its subfolders without to know each module by name.

So i decided to implement some themes in my AIR app. I have converted my CSS files into SWF files, removed the Style linkage from my main file. Based on the user preferences stored in a file, I decide which theme to use. i.e; load the SWF file using StyleManager class.
I made my application window invisible, added a StyleEvent.COMPLETE event listener for the IEventDispatcher object returned by StyleManager.loadStyleDeclarations method. After the StyleEvent.COMPLETE occurs, I made my main window visible.
The problem i have now is, for a few seconds, i can see white canvases and all my components without any styles before using the style selected. I want to know if my approach is correct or do I need to make any changes to implement this properly?

My application has a couple of modules which am loading as thus in my application.
<local:moduleloader url="Module1.swf" id="modulel" />
<local:moduleloader url="Module2.swf" id="module2" />
Then while loading each module I am showing the progress bar. The progress bar shows but does not go away. It remains above the whole frame of the application. The module loader is as follows:(Also note that in Flex 3 the same works, but am using Flex 4 and in Fx 4 it does not)
<mx:ModuleLoader xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

I am trying to load a flash game in flex but the game does not work the same as it does in the flash player. The game was made using AS2 but I read somewhere that is should play without errors, that is not the case. Played normally the guns shoot the enemies no problem but in flex the bullets just float around the enemies never hitting them. It is hard to describe what is happening so I also included a link with the flex 3 project file that has all of the files.
Here is what I am using for my flex 3 code.
Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="[URL]" layout="vertical"
creationComplete="init()">
<mx:Script>
<![CDATA[
private function init():void{
[Code] .....
So is there a way to just play the swf file without messing up the game?

As some of these languages have very big font sizes (e.g. Chinese), I do not want to load all these fonts into the app. at once but was thinking to put them into different modules and then load only the specific module (depending on which language is chosen in the main app). For this I moved the style part from the main app:
<mx:Style>
@font-face
{
font-family:DedicatedFont;
[Code]....
into the different modules. Above one is e.g. for the Chinese font (cma.ttf).
The modules are created and I can also use the fontstyle (DedicatedFont) in the module itself, but I can not access it from my main application.

We have a Flex app that is currently loading an XML file that contains Multiple Choice Question data. I don't want a user to be able to access this file via http, but if I use HTTPService to load the file (what we're doing currently) it seems as though I have to place the XML file within the public_html folder on our server.
Is there a better way to load the XML file so that users wouldn't be able to see it in their activity viewer/access it via http://

What would be the best way of figuring out what the total progress of the images that are loading? I was thinking it would be cool to use a generic loader and apply it to a function such as
myScroller.loadImages();

I am loading multiple images into a class instance and I would like to keep track of how large the complete amount of loaded data is at any given point.I have grabbed the totalbytes from my directory of images via a PHP script... but collecting the new bytes from the ProgressEvent on each image seems tricky for some reason.Let's assume that the totalBytes variable is correct and that I am totally unfamiliar with the way that ProgressEvent works.Does an event get fired every time ProgressEvent gets a new byte? If not, how do I keep track of the current total bytes?[code]
