OnCollision sending empty information [please move this to Kart Kit forum]

Hi guys, I'm having some problems with the OnCollision callback on TGB Kart Kit.

When I use the onCollision method of a t2dSceneObject...

function wallCollision::onCollision(%this, %object, %srcRef, %dstRef, %time, %normal, %contacts, %points)

...the properties of it (%srcRef, %dstRef, %time, %normal, %contacts and %points) are empty.

Anybody have had this problem?

Other problems:

• All resolve collisions of TGB (clamp, sticky) are having the same behavior.
• The onCollision method is beeing called without any collision.

Any answer will be useful!!
Thanks!
