Strange occurence with move callbacks

[koocake]

I have set up a move callback class in a similar way to the collision callback class i defined before.
My class looks like this:


#include "car_move_callback.h"

SCF_IMPLEMENT_IBASE(Car_Move_Callback);
SCF_IMPLEMENTS_INTERFACE (iDynamicsMoveCallback);
SCF_IMPLEMENT_IBASE_END;

void Car_Move_Callback::Execute (iMeshWrapper* mesh, csOrthoTransform& t)
{
  csPrintf("Car moved!");
}

void Car_Move_Callback::Execute (iLight* light, csOrthoTransform& t)
{
}

void Car_Move_Callback::Execute (iCamera* camera, csOrthoTransform& t)
{
}

void Car_Move_Callback::Execute (csOrthoTransform& t)
{
}

However, when I set the move callback to the car's iRigidBody, upon starting the application, the car gets placed at a strange location stuck in the wall of the room, rather than its usual place. When I comment out the code to set the move callback, the car is positioned as normal. This is the code with the move callback set commented out.

 
  iDynamicsCollisionCallback* ccb = &collCallback;
  //iDynamicsMoveCallback* mcb = &moveCallback;
  car->SetCollisionCallback(ccb);
  //car->SetMoveCallback(mcb);
  car->Update();

Any idea as to what is happeneing here?
