What makes 2 ScalarMaps the same?

Hi,

  I asked this as a followup question but maybe it was overlooked.  I'm
getting this exception:

visad.BadMappingException: Display.addMap: two ScalarMaps with the same
RealType & DisplayRealType

  I have a loop that is going through a vector of data sets.  Each pass
new ScalarMaps are being created...the maps are local to the loop.  I
know you can't reuse a ScalarMap but I though creating new ones each
pass would do the trick.  I guess I thought wrong...any suggestions?
