[SOLVED] Do Collisiongroup woks with kinematic?

Hi,
I am trying to remove collisions with an kinematic by just removing the collisiongroup, but its not working. Case test is the TestKinematicAddPhysicsSpaceIssue , add line 94 :

node2.getControl(RigidBodyControl.class).removeCollideWithGroup(PhysicsCollisionObject.COLLISION_GROUP_01);

Not working, I expected the collision to not happen.

Never-mind, it do works.
For who that has the same problem, just look at the functions :
setCollisionGroup and setCollideWithGroups
