Help! Transformation point hell

I have been stuck trying to create the simplest of tweens, one that took seconds in Flash. 

 

Basically I have a 2px cube that i want to tween into an extending line by scaling the cube down the way. I set the transformation point in the first keyframe to top centre, create the final keyframe with the TP set top centre as well. Create a classic tween between them and then scale the cube on the final keyframe to the desired length.

 

However, everytime i then view the tween, the TP moves on the final keyframe rendering the animation useless. 

 

Why is it doing this and what can I do to enable this simplest of tweens. 

 

Any help is appreciated.

You aren't moving the transformation point of the final shape after creating the end keyframe, are you?

It looks like scaling is buggy when the transform factors get into the thousands of percents. I'd recommend using a shape tween instead. Or, instead of scaling a small symbol up, scale a large symbol (the full-size line in your case) down.
