Intersecting Error

[Johannes]

Hi,
just had the following error:

Traceback (most recent call last):
File "050407_SynchroGoodIntersect.py", line 1529, in moveGliderEven
moveBall(i,ball0503)
File "050407_SynchroGoodIntersect.py", line 1719, in moveBall
info=object.intersect(ball.lastPos0504,ball.actual Pos.get())
File "C:\Program Files\Vizard25Alt\viz.py", line 2207, in intersect
return VizIntersect(_ipcSendHold(_VIZ_INTERSECTLINE,MAIN_ SCENE,self.id,'',lineEnd[0],lineEnd[1],lineEnd[2],0))
File "C:\Program Files\Vizard25Alt\viz.py", line 2999, in __init__
self.object = _GetNode(data[7])
File "C:\Program Files\Vizard25Alt\viz.py", line 1163, in _GetNode
return _GlobalNodeList[id]
KeyError: -1


happens when I do this:
info=object.intersect(ball.lastPos0504,ball.actual Pos.get())
