Description

Steps to reproduce:
Created an application like this
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" preloader="CustomPreloader" />

CustomPreloader.as looks like this
package
{
import mx.preloaders.DownloadProgressBar;

public class CustomPreloader extends DownloadProgressBar
{
public var wcs:WelcomeScreen;

public function CustomPreloader()

{ super(); wcs = new WelcomeScreen(); this.addChild(wcs) }

}
}

WelcomeScreen.as looks like this

package
{
import flash.display.Loader;
import mx.core.Application;

public class WelcomScreen extends Loader
{
public function WelcomScreen()

{ trace(mx.core.Application.application); }

}
}

mx.core.Application.application should be null. But instead i'm getting a RTE.

Actual Results:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

at mx.managers::SystemManager/initHandler()[E:\dev\flex_3_beta2\sdk\frameworks\projects\framework\src\mx\managers\SystemManager.as:2206]

Expected Results:

I've give a very simplified test to show the problem.
I'm actually accessing a variabe on mx.core.Application.application but this was good enough to show the problem

Workaround (if any):
