[visad] NPE when mapping to IsoContour

Hello,

When I switch my working mapping from Display.RGB to Display.IsoContour, I
recieve NullPointerExceptions and ArrayIndexOutOfBoundsExceptions, both for
2D and 3D displays.

Please have a look at the attached stack trace.

I use VisAD Tue Dec 23 13:47:46 CST 2008.

Is this a known issue ?

Sebastian
