AS :: Flex :: Dynamic Loading And Compilation Of MXML / At Runtime
Jan 14, 2010
I am trying to build an application which has a flex front-end and a php back-end. I am struggling to do something with this application which I couldn't figure out a way to do. I would want my flex application to show a view based on an MXML it recieves from the server as a response to some interaction in the flex application. for example, lets say there are two buttons on the current view and if i press the first button, it will load one mxml/as3 from the server, and when i click the other, it will load a different mxml. How do you think i can tackle this situation? how to do this as i've been banging my head on the wall trying to figure out a way.

Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?

In Flex it is now possible to use the -define compiler option to do all sorts of cool stuff.In my program, I am using the option such that some of my code is excluded by blocks like this:
CONFIG::FACEBOOK{
//Some code
}
And this is working well.How do I get a similar behaviour with MXML?I want to do the same thing, but omitting/including MXML tags in this way, not blocks of AS code.

I know how to add stages in actionscript but i don't know how to add children to them stages.
This is how I make my states.
var state1:State = new State();
state1.name = "state1";
states.push(state1);

I have to work with a .fla file. I would like to rewrite this file in AS3. Is it possible?
I mean, I would get a .swf file as result of compilation of mxml file in Flash Builder 4 IDE, not Flash CS5 (I don't know CS5, I'm a newbie) . Main target is getting a .swf file by compilation of mxml file, not fla file. Could you explain in detail how this code works? For example what's TXT ? Is it a inputText? Where is this variable defined?
Now I 'm linking .fla file ....

Has anyone got any experience will loading SWC / SWZ's at runtime within a Flex 4 / Air 2 desktop application?The very rough idea would be to have a desktop Air app, which is able to "download" additional modules (eg, a SWZ/RSL representing a form) and load these at runtime?
Imagine the App is configured using an XML file obtained over the net. When this has instruction to get a new module (SWZ/RSL), the app will download the module to its App Storage folder, and instanciate it at runtime?The Flex Manual seems to indicate this is possible, but is talking web rather than desktop http:[url]....

According to the Adobe asdocs, Flex framework files are supposed to be able to be loaded at runtime. These localized framework files, the ones that exist at (on windows) C:Program Files (x86)AdobeAdobe Flash Builder 4.5sdks4.5.0frameworkslocale, are responsible for items such as button text on Alert Dialogs, and a host of other controls. My expectation is that once these framework files are loaded I would see these resources available in my Flex app.
I've set up my project as follows:
MyProject
-src
-Flex4.5
-Referenced Libraries
[code]....
Now the asdocs state that in order to do this, you have to set the compiler settings to read
-locale=en_US,da_DK,de_DE,es_ES,fi_FI,fr_FR,it_IT,ja_JP,ko_KR,nb_NO,nl_NL,pt_BR,ru_RU,sv_SE,zh_CN,zh_TW -allow-source-path-overlap=true -source-path=locale/{locale}
which I have done.My Build Path Libraries for Flex 4.5 - C:Program Files (x86)AdobeAdobe Flash Builder 4.5sdks4.5.0 are set to be Runtime Shared library (of note, the {locale} subfolder says "Merged into code")
But when I change the language in the browser, I'm not seeing any of the framework resources.Also, when I build my project, I don't see any indication of the locale-oriented resource files in the bin-release. Since we only deploy the contents of the bin-release folder (and not the entire project), how is this supposed to work?I am also seeing .swz files in my bin-release (and I know these arent the localized framework resources).
Does anyone have any experience with Runtime Framework Localization?? What am I doing wrong? My expectation is that once I build my project (with the framework resources externalized) that the app would be able to load those resources, but this isn't happening and I am not interested in compiling a different version of my app for all of the locales I support.

I am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"

It seems it isn't possible at runtime to change styling defined in CSS files, ex.: colors. This is seemingly because the CSS files are compiled into SWF. Is it possible to externalize styling information in CSS (or any other format) without compiling it to SWF file so that it can be changed easily at runtime just as normal CSS can be changed when it is used in HTML.

I'm having an odd problem that isn't mission critical since I can use the command line with no probs.In my earlier post http:[url]... I had problems getting the web compiler to work.Now that it's working I use this in a browser to compile: http:[url]...
and I get this error as a result:
ERROR : Could not resolve to a component implementation.
349 <mx:filters>
350 <mx:DropShadowFilter alpha=".25" angle="90" />
351 </mx:filters>
Everything is legit and the most recommended solution is that the namespaces aren't correct. I've checked those and they're fine. Other answers I've come across relate to external components causing a problem but as you can see, I'm not using an external component.Here's the kicker. If I do a compile via command line:
mxmlc topsight.mxml
it compiles perfectly.Specs are still the same from the prior post and I'm using the Flex 3 SDK.Not sure if this would help but I did the download from http:[url]... and I clicked on the Open Source Flex SDK - Milestone 3.3

I am trying to set some public static constants on a class conditionally by passing variables to the compiler e.g. -define=CONFIG::ENVIRONMENT,'testing_server'
[Code]...
Obviously this means I have to tinker with long command line setting each time. I thought my initial approach was possible given the documentation and various tutorials I have read.

Is there a simple way to report the time necessary to compile an applcation in Flash Builder (in the Console or an external file) ?
I want to compare the average compilation time between the usual Flex compiler and HFCD (HellFire Compiler Daemon) for a given project.

I'm building a Flex/AIR application that connects to a remote server, the URL of which changes depending on the environment (development/production, and possibly others). For now, this URL parameter is hardcoded in my root application MXML file but it means I have to change it everytime I build my app for a different environment.Is there a way to externalize such a parameter so that when Flash Builder automatically builds my app (in development mode), it uses the development URL

I have a web application written in Flex and I'm trying to build an AIR application from the same code base using conditional compilation.
In the AIR application, I need to have import statements such as the following: import flash.data.SQLConnection; import flash.filesystem.File; but I cannot have these import statements in the web application because they are AIR only classes.
[Code]...
and similar approach to include web or AIR specific functions during compilation. The approach seems to have worked so far The only place I have run across issues is in my Cairngorm's model locator. If I put CONFIG::desktopMode around import statements in Cairngorm's model locator, it starts giving "Uncaught exception in compiler" or "1131 classes must not be nested" error. I'm not sure how to address this error!

I moved from using the Flex Builder 3 IDE to Flash Builder a couple weeks ago and have noticed a ridiculous jump in compile times with the same project. It almost seems like every time I build it does a clean build. The project I am working with is pretty big, but when it takes more than 4 mins to build, something is wrong. I tried adding more memory to eclipse and all the tricks I could find on the web but the compile time never really changed. I am running under Windows 7 32bit, and I get the same performance from the plugin and stand alone version of the IDE.

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

This is a project I'm working on for a simple demo tutorial application in Flex. I am using mxml pages. You can see to the left that I will have my main application and then other mxml files (In the Examples Package) as the examples that will be loaded into the main application mxml. How can I dynamically pull the value from the object in the list to load the child mxml file into the container that I have further down in the application?

I would like to include an MXML file in my MXML file in the same way you can include an external file in AS3 using the include directive. Using the include directive brings the code from the external file into the original file at compile time placing it in the same scope. For example,
Application.mxml:
<Application>
<source="external.mxml"/>

In AS3 you can pass a constant to the compiler -define+=CONFIG::DEBUG,true And use it for conditional compilation like so:
CONFIG::DEBUG {trace("This only gets compiled when debug is true.");}
I'm looking for something like #ifndef so I can negate the value of debug and use it to conditionally add release code. The only solution I've found so far was in the conditional compilation documentation at adobe and since my debug and release configurations are mutually exclusive I don't like the idea of having both DEBUG and RELEASE constants.
Also, this format works, but I'm assuming that it's running the check at runtime which is not what I want:
if (CONFIG::DEBUG) {
//debug stuff
}
else {
