Properties not being saved?

Hello. I'm incredibly new to ActionScript and to making widgets. I need some help with my widget's code. What it does is ask for a url and then at runtime checks that url to see if the password entered is valid. If yes, success. If no, failure.
I've gotten it to work with a hard-coded url in it but I thought the widget would be more useful if the widget could be configured for a url.
I think what's going wrong is the properties aren't saving.
The AS code is below. I can provide the FLA if needed.

{

import widgetfactory.InteractiveWidget;
import widgetfactory.events.WidgetEvent;
import flash.display.MovieClip;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.MouseEvent;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLVariables;
import flash.net.URLRequestMethod;
import flash.net.URLLoaderDataFormat;

public class passwordProtect extends InteractiveWidget
{

private var textFieldDefaultText:String = "http://";

override protected function enterPropertiesDialog ():void
{
gotoAndStop(2);

checkProperties();

rwURL.text = properties.textFieldText;
}

private function checkProperties():void
{
if (properties.setBefore == true)
{
textFieldDefaultText = properties.textFieldText;

}
}

override protected function saveProperties ():void
{
properties.textFieldText = rwURL.text;
properties.setBefore = true;

}

override protected function enterStage ():void
{
gotoAndStop(3);
}

override protected function enterRuntime():void
{
gotoAndStop(1);

stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.showDefaultContextMenu = false;

//path to the remote file on your server
var remotePath:String = properties.textFieldText;

login.addEventListener(MouseEvent.MOUSE_DOWN, loginDown);

function loginDown(e:MouseEvent):void
{
hideHint();
//check to see if something in the pass text field
if (rwPassword.text != "")
{
sendLoadData();
}
else
{
showHint();
}
}
stop();

function sendLoadData():void
{
var dataRequest:URLRequest = new URLRequest(remotePath);
dataRequest.method = URLRequestMethod.POST;

// define the custom parameters that will be sent to the remote file
var params:URLVariables = new URLVariables();
params.rwPassword = rwPassword.text;

dataRequest.data = params;

var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
urlLoader.addEventListener(Event.COMPLETE, urlLoaderComplete);

try
{
urlLoader.load(dataRequest);
}
catch (event:Error)
{
showHint();
}
}

function urlLoaderComplete(event:Event):void
{
// once all the data has been sent and we'll check for a message sent
// from the remote file to tell us if the operation has ended with success or not
errorHandler(event.target.data.secure_response);
}

function errorHandler(message:Number):void
{
// check the message that was sent back from the remote file
//trace(message);
if (message == 1)
{
setSuccess();
}
else
{
setFailure();
}
}
}
}
}

Thanks for any help you could provide!
