ProLoader and TLF TextFields do not work together!

I'm using ProLoader to load a .swf that uses TLF.  The master .swf loads the target .swf and all code executes as expected with one minor glitch: the content of the loader is white/blank.  Has anyone else seen this!?

~~~~~~~~~~~~~~~~~~~~~~~~

Here is the full bug report that I tried to send Adobe, but they cap reports at 2000 characters and provide no option for uploading a source .zip. (Seriously, Adobe?)  If you have time, and follow my instructions you will see how ProLoader won't even load a .swf with TLF on its stage.  (Yes, I realize this different from my problem, but I'd like to demonostrate how buggy and inconsistent ProLoader is.  The simple solution would be not to use TLF, and mostly likely, I will end up doing that.)

******BUG******

ProLoader loads .swf with TLF, but ProLoader is blank.

Steps to reproduce bug:

1.  Download sample files (http://helpx.adobe.com/content/dam/kb/en/141/tn_14190/attachments/Load_External_SWF.zip) from the Tech Note, Load external SWF into another SWF (http://helpx.adobe.com/flash/kb/load-external-swf-swf.html).

2.  Open ExternalSWF.fla and assign it a document class.

Here is mine:

package  {

          import flash.display.MovieClip;

           import flash.events.Event;

          public class ExternalSWF extends MovieClip {

                    public static var DATA_LOAD_COMPLETE:String = "ExternalSWF_DataLoadComplete";

                    private var data_:String;

                    public function ExternalSWF() {}

                    //This function will be called from the .swf that loaded me.

                    public function loadData(data:String):void

                    {

                              data_ = data;

                              dispatchEvent(new Event(DATA_LOAD_COMPLETE));

                    }

                    public function get data():String { return data_; }

          }

}

3.  On ExternalSWF.fla's stage, change a classic TextFields into a TLF TextField.

4.  In Loader_Movie.fla, change all flash.display.Loader instances to fl.display.ProLoader in order to load TLF TextFields.  Also, add an event listener to myLoader for Event.COMPLETE.  Here are my Loader_Movie.fla's Actions:

import flash.events.Event;

import fl.display.ProLoader;

var myLoader:ProLoader = new ProLoader();                     // create a new instance of the ProLoader class

var url:URLRequest = new URLRequest("ExternalSWF.swf"); // in this case both SWFs are in the same folder

myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, myLoaderIsLoaded);

myLoader.load(url);                                     // load the SWF file

addChild(myLoader);                                     // add that instance to the display list, adding it to the Stage at 0,0

myLoader.x = 10;                                        // move the loaded SWF 10 pixels to the right (from the left edge)  

myLoader.y = 175;                                       // move the loaded SWF 175 pixels down from the top

// (optional) load a second external SWF file

var my2ndLoader:ProLoader = new ProLoader();

var url2:URLRequest = new URLRequest("ExternalSWF2.swf");

my2ndLoader.load(url2);

addChild(my2ndLoader);                                  // optionally, you could put the 2nd SWF beneath

                                                        // the 1st by using addChildAt(my2ndLoader, 1);

// (optional) scaling of the 2nd SWF file

my2ndLoader.scaleX = 2;                                 // scale the SWF horizontally by 200%

my2ndLoader.scaleY = 2;                                 // scale the SWF vertically by 200%

function myLoaderIsLoaded(event:Event):void

{

          trace("The first .swf has loaded so add event listeners");

          var swf:ExternalSWF = ExternalSWF(myLoader.content);

          swf.addEventListener(ExternalSWF.DATA_LOAD_COMPLETE, allFinished);

          swf.loadData("foobar");

}

function allFinished(event:Event):void

{

          trace("Here is the data we loaded: " + ExternalSWF(myLoader.content).data);

}

Results:

[Trace] Output

ReferenceError: Error #1056: Cannot create property __id0_ on ExternalSWF.

          at flash.display::Sprite/constructChildren()

          at flash.display::Sprite()

          at flash.display::MovieClip()

          at ExternalSWF()

ExternalSWF is invisible; 4 loading dots appear instead.

Expected results:

Both .swfs load without incident.

Trace output:

The first .swf has loaded so add event listeners

Here is the data we loaded: foobar

Additional notes:

I discovered this bug when my main/master .swf used ProLoader to load another .swf (with TLF on a symbol in the libary).  In this case, the ProLoader appeared blank/white, not even the 4 loading dots.  However, all the code in both .swfs still ran as expected (shown via the Output panel dumping all expected trace statements until execution finished).
