R – Monitor the console output from within the actionscript – flash application

The fl.* hierarchy of classes is Flash CS3-only. It's the Flash Components 3 library (I believe it's called, I might be wrong). However, you don't need the class to work with the object. As long as you can get a reference to it in your code, which you seem to have, you can assign the reference to an untyped variable and work with it anyway:

var textInput : * = getTheTextInput(); // insert your own method here

textInput.text = "Lorem ipsum dolor sit amet";

textInput.setSelection(4, 15);

There is no need to know the type of an object in order to interact with it. Of course you lose type checking at compile time, but that's really not much of an issue, you just have to be extra careful.

If you really, really want to reference the object as its real type, the class in question is located in

Adobe Flash CS3/Configuration/Component Source/ActionScript 3.0/User Interface/fl/controls/TextInput.as

...if you have Flash CS3 installed, because it only ships with that application.

Not sure I get exactly how the application works so excuse me if I'm wrong. If the flex instance must load the AVM1 proxy wouldn't it be possible to inject a flash-var via the URL containing a generated ID for the LocalConnection to use ?

In addition to your comment, just added how to send variables to the AVM1 movie. This works fine locally at least (not tested on network):

AS3 - FP10:

loader = new Loader();

var request:URLRequest = new URLRequest("as2proxy.swf");
var variables:URLVariables = new URLVariables();
variables.id = "local_connection_id";
request.data = variables;

loader.load(request);

AS2 - FP7 (first frame on the timeline of "as2proxy.swf") :

trace(id); // (_root.id)

BTW, stumbled on the following class from Libspark : http://www.libspark.org/svn/as3/ForcibleLoader/src/org/libspark/utils/ForcibleLoader.as
