When I started using FABridge I had some issues because I was using swfobject to include my Flash. I was able to resolve the issues, and others might be interested in using FABridge and swfobject together.

I just tested it out myself and you can definitely compile in Flash with only the 6 Flex classes above. You should have no references to any other classes.

- firstly, note the comment about EULA

- this will enable you to build an app just like the FABridge sample apps found on the Adobe website

- I got this working using Flash CS3 only (I don’t have FLEX) but you’ll need to get the above mentioned .as files and .js file from inside the SDK which you download from http://download.macromedia.com/pub/labs/flex/3/flex3sdk_b3_121207.zip

- I followed the exact instuctions above but at compile time of the flash application FABridge.as threw a compile error because it couldn’t resolve a reference to something like mx.controls.Alert (this implies that extra classes need adding to the classpath) anyway, I got bored of going through the library finding specific classes to copy so I just copied the lot.
* To do this unzip the download and then locate \frameworks\projects\framework\src and copy src to somewhere on your hard drive, like “C:\Flash classes” (can be anywhere) and then add a classpath entry…

- …to add a classpath entry that will be present for every project you work on you’ll need to go to Edit > Preferences… > ActionScript > ActionScript 3.0 Settings…
Click on this. You should see:
.
$(AppConfig)/ActionScript 3.0/Classes
now click the + symbol and add
C:\Flash classes (or where ever you put it)

- to get started create a new Flash File (AS3), set Document Class: Initializer (don’t worry about the warning message), then create a new ActionScript File and save it as Initializer.as and it’s contents should look like:

package {
import flash.display.MovieClip;
import bridge.FABridge;

public class Initializer extends MovieClip {

private var externalBridge:FABridge;

public function Initialiser() {
super();
externalBridge = new FABridge();
externalBridge.rootObject = this;
}
}
}

- now just add components like buttons etc to your stage. Give them names like btnSayHello, and then publish your project to a SWF.

- now you’ll have to write some javascript code that makes use of the FABridge.js file and you’ll have to learn the special way in which you reference your components like “btnSayHello”.

… i’ll leave that to someone else to contribute!
