object disappears after move in flex 3

I am trying to prepare a simple animation of photos in flex. I got most of it done but when ever i do the following

<mx:Sequence id="bird" target="{birdImage}">
    <mx:Move xFrom="-100" yFrom="-100" xTo="100" yTo="100" duration="700" effectEnd="{bird2.play()}" easingFunction="mx.effects.easing.Quadratic.easeIn" />
</mx:Sequence>

The pr开发者_JAVA百科oblem is that after the move before the next part starts the image disappears. What am i doing wrong here?

I had a similar trouble with moving two panels in a Hbox. The solution was to set the container's autoLayout property to false just before the effect starts. If you are in a similar situation hope it helps.

Bye!
