Проблема с инициализацией переменной

[silin]

public class Parent 
{
	public var a:Boolean = false;
	trace("Parent: init members");
	public function Parent() 
	{
		trace( "Parent: ctor" );
 
	}
 
}

public class Child extends Parent 
{
	trace("Child: init members");
	public function Child() 
	{
		trace( "Child: ctor" );
		super();
 
	}
}

var test:Child = new Child();
/*
Parent: init members
Child: init members
Child: ctor
Parent: ctor
*/
