how to load PDF (HTML Loader) with File Reference (dialog box) [AIR]?

Hi.  I'm trying to get my AIR application to load a PDF document from the dialog box using File Reference Class.

With the code that I have if I use a regular Loader then I can get a PNG image to load into a container and display on the screen.  But PDF's require HTML Loader which seems not to accept event.target.data because it is expecting a String.

This is the error I got

TypeError: Error #1034: Type Coercion failed: cannot convert "[object FileReference]" to flash.net.URLRequest.

Here is my code:

import flash.net.URLRequest;

import flash.display.MovieClip;

import flash.html.HTMLLoader;

import flash.net.FileReference;

import flash.net.FileFilter;

var file:FileReference=new FileReference();

var container:MovieClip=new MovieClip();

addChild(container);

var i:Number=1;

// button is an object on the stage, not being called via actionscript

button.addEventListener(MouseEvent.CLICK, showDialog);

var myFile:FileReference;

var myFileLoader:HTMLLoader;

function showDialog(e:MouseEvent):void{

    myFile=new FileReference();

    var PDFFileType:FileFilter=new FileFilter("PDFs (*.pdf)","*.pdf");

    myFile.browse([PDFFileType]);

    myFile.addEventListener(Event.SELECT, selectFile);

}

function selectFile(e:Event):void{

    myFile.addEventListener(Event.COMPLETE, loadFile);

    myFile.load();

}

myFileLoader=new HTMLLoader();

function loadFile(e:Event):void{

myFileLoader.load((e.target).toString());

}

(with the new forum selection I also can't seem to put this topic into the ActionScript location of the forum for Flash Pro.)
