For anyone interested, I was able to get this to work normally when
building or with a loader passing flashvars:
package
{
import flash.display.Loader;
import mx.core.Application;
public class MyApplication extends Application
{
public function MyApplication()
{
super();
}
override public function get parameters():Object
{
if(systemManager.document.parent.parent is Loader)
return
systemManager.document.parent.parent.loaderInfo.parameters;
else
return super.parameters;
}
}
}
