[Laszlo-dev] For Review: Change 20080616-ptw-q Summary: Make, LzTrackService activate/deactivate parallel

[André Bargull]

Won't this throw a nullpointer-exception, if you call "deactivate" and 
the active-groups array is still/again null?
Like:
<canvas>
  <handler name="oninit" >
    lz.Track.deactivate("foobar");
  </handler>
</canvas>
