Adding&Playing new animations

I want to play some animations when user presses the corresponding keys.

I added

C++, to the player class:
-------------------------------

void Player::playAnimation(const char *Animation){
	setState(NullState);
	setActionThread(Animation, false, false, true);
}

void Player::stopAnimation(){
	setState(MoveState);
}

ConsoleMethod( Player, playAnimation, void, 3, 3, "Return the current state name.")
{
	object->playAnimation(argv[2]);
}

ConsoleMethod( Player, stopAnimation, void, 2, 2, "Return the current state name.")
{
	object->stopAnimation();
}

Client side:
--------------

function PlayAnim(%AnimationName){
    commandToServer('PlayAnim', %AnimationName);
}

moveMap.bind( keyboard, t, "PlayAnim(\"wave\");" );

Server side:
---------------

function Armor::animationDone(%this,%obj)
{  
	%obj.stopAnimation();
}

function serverCmdPlayAnim(%client, %Anim){
	echo("serverCmdPlayAnim: " @ %Anim);
	%client.player.playAnimation(%Anim);
}

When i press 't' key for the first time, the animation is playing successfully, then stops and return to idle animation.
But when i press 't' key again, animation doesn't play.

Do you know where the problem is?

My player.cs file is:

datablock TSShapeConstructor(m1)
{
   baseShape = "./player01.dts";
   sequence0 = "./idle.dsq root";
   sequence1 = "./walk.dsq back";
   sequence2 = "./walk.dsq run";
   sequence3 = "./walk.dsq side";
   sequence4 = "./wave.dsq wave";
};
