[flexcoders] Using Tweener for effect (such as showEffect)

[dave_defusion]

I would like to use the Tweener class for my showEffect & hideEffect,
however with Tweener whenever you add a tween it kicks off straight
away. I tried doing my tween inside a method and using that as the
effect e.g.:

this.setStyle( 'showEffect', this.testShowEffect );

private function testShowEffect ():void
{       
        trace( 'testShowEffect ' );
        Tweener.addTween( this, { y: this.height, time: 1 } );
}

But that method doesn't get called when I change the visible to true.

Any ideas?
