Question about shape movement

Hi all,

What I am trying to do is to register in DB the item position when thrown by player.

Now my problem is that I always get the player position (object spawn position) here is the code where I spawn the object :

%obj = new Item() 
	{
	    datablock = %datablock;
	    rotation = "0 0 1 " @ (getRandom() * 360);	
	    //static = true;
	    //rotate = true;
	};

        MissionGroup.add(%obj);

	%throwForce = %player.throwForce;
		
	if (!%throwForce)
		%throwForce = 20;
		
	// Start with the shape's eye vector...
	%eye = %player.getEyeVector();
	
	%vec = vectorScale(%eye, %throwForce);

	// Add a vertical component to give the object a better arc
	%verticalForce = %throwForce / 2;
	%dot = vectorDot("0 0 1",%eye);
	if (%dot < 0)
	  %dot = -%dot;
	%vec = vectorAdd(%vec,vectorScale("0 0 " @ %verticalForce,1 - %dot));

	// Add the shape's velocity
	%vec = vectorAdd(%vec,%player.getVelocity());

	// Set the object's position and initial velocity
	%pos = getBoxCenter(%player.getWorldBox());
	
	%obj.setTransform(%pos);
	%obj.applyImpulse(%pos,%vec);

	// Since the object is thrown from the center of the
	// shape, the object needs to avoid colliding with it's
	// thrower.
	%obj.setCollisionTimeout(%player);
        
        RegisterObjectPosition(%obj) ;

In RegisterObjectPosition I use %obj.getTransform() to get object position but it's still the original position.

Is there a callback or something that could help me there ?

I tried to use onStickyCollision() but it does not work, it's never called.

Thanks in advance for any help.

Regards,
