[Tinyos-help] location plugin

[Pela]

I'm trying to use tinyviz and the location plugin. I copied
FakeLocation.nc and the other files from TestTinyViz to my own
application directory. It works, but every time I call the getLocation()
command, the locationDone() event is signalled three times (I suppose it
should be signalled only once). How can I prevent these triple event
call (now I'm counting how many times the event function is called) ?
