problem with path animation

[jelly]

I noticed that it's not good to have a function with the same name is an object "maze1" so I cahnged the fucntion name to "maze1trial". This, however still has not solved my problem. I wonder why the viewpoint does not reset to the start position, or why the animation does not play again, respectively? I played around with the viewpoint and thought it may be because of the link, so within the trial, at the very end, I am also unlinking, just to be sure. Still did not solve the issue. I would just like the maze objhect to lead and then the viewpoint animation to be played 4 times (as in repeating the animation 4 times, one after the other).

It now looks like this:

import viz															#Needed to generate a world.
import viztask														#Needed to control the experiment structure.


viz.mouse.setVisible(viz.OFF) 										#Stops the mouse appearing on the screen.
viz.mouse.setOverride(viz.ON)										#Stops Vizard navigation using the mouse.

viz.clearcolor(viz.BLACK)


#Set the start position:
startPos = [-6.4,0,-8]


viz.go()


### Add all the resources. ############### 

maze1 = viz.add('Objects/Maze_1.dae')
maze1.visible(viz.OFF)

#Add a sky with an environment map.
env = viz.add(viz.ENVIRONMENT_MAP,'sky.jpg')
dome = viz.add('skydome.dlc')
dome.texture(env)

view = viz.MainView 

view.eyeheight(1.4)
view.setPosition(startPos)
view.collision(viz.ON)
viz.collisionbuffer(.8)

viewNode = viz.addGroup()
viewLink = viz.link( viewNode, viz.MainView)
viewNode.setPosition([-6.4,0,-8])

##Animation path

pathMaze1 = viz.addAnimationPath()

#Add control points to the path, along with their time stamp.
pathMaze1.addControlPoint(0,pos=(-6.4,0,-8),euler=(0,0,0),scale=(2,2,2))
pathMaze1.addControlPoint(2,pos=(-6.4,0,-8),euler=(90,0,0),scale=(2,2,2))
pathMaze1.addControlPoint(4,pos=(0,0,-8),euler=(0,0,0),scale=(2,2,2))
pathMaze1.addControlPoint(8,pos=(0,0,5),euler=(0,0,0),scale=(2,2,2))

#Duation of animation
pathMaze1Duration = pathMaze1.getDuration()


#Loop the path in a swinging fashion (point A to point B to point A, etc.).
pathMaze1.setLoopMode(viz.OFF)


def maze1trial():
	print 'now'
	maze1.visible(viz.ON)
	viewNode.setPosition(-6.4,0,-8)
	link = viz.link(pathMaze1,viewNode)
	yield pathMaze1.play()
	yield viztask.waitTime(pathMaze1Duration)
	link.remove
	maze1.visible(viz.OFF)


def masterFunction():								
	for x in range(4):
		yield maze1trial()
		
viztask.schedule(masterFunction())
