That is correct, it only fails when if comes time to replace data
in the display.

        display.clearMaps();

by itself, does not seem to do the trick.  i noticed 2 lines in setting up
the contour widget:

        ScalarMap mapContour=(ScalarMap)display.getMapVector().lastElement();
        contourWidget = new ContourWidget(mapContour);

Do i have to update the ScalarMap for the contour widget as well?  If that
is true, do i use this class ContourWidget.ContourRangeSlider?  i noticed
it has a method:

        ContourRangeSlider.mapChanged();

Do i also have to call this method?  Does anyone know the actual syntax of
accessing this class?  The documentation says it is an inner class of
Contour Widget.
