[0.0, 0.0, 0.0] for every object.getPosition()

[migoloco]

I am trying to use viz.pick() to get the position for an object that a click on, but all I get is [0.0, 0.0, 0.0]. What am I doing wrong? Here is a simple example code:

import viz
viz.go()
import vizcam
viz.cam.setHandler(vizcam.KeyboardCamera())

viz.add('gallery.ive')

def showPicked():
object = viz.pick(0)
if object.valid:
print object.getPosition()

vizact.onmousedown(viz.MOUSEBUTTON_LEFT, showPicked)

Thank you very much.
