Behavior troubles - values not set - owner lost

I'm doing a simple little game to mess around with physics and pipeline to get it from PC to iPhone.

I started with a ball and some paddles and made the ball bounce around and the paddles bounce the ball too.

Then I added a space invader to have something to hit with the ball for points and added these two behaviors.

1. in the first code - MoveOnScreenRandom::onUpdate - it can't find the owner.
"scripts/behaviors/moveOnScreenRandom.cs (36): Unable to find object: '' attempting to call function 'setLinearVelocityX'";

2. in the second piece of code - the level - I have set the verticalSpeed and horizontalSpeed to something other than the defaults and they are not being recorder in the level file...

Do I have to do something special for behaviors in iTorque2D?
