Unless you call display.clearMaps(), the Display keeps all the
ScalarMaps around.  You can call display.getMapVector() to
get a list of the display's current list of Maps.  You might
want to grab that list and print it on each pass to help debug
what's happening.

As Doug said, I'd guess you already added the ScalarMap in a
previous pass, which is why you're getting the error.
