Thanks Bill,

I gave it a try and received the following error:

java.lang.ArrayIndexOutOfBoundsException: 48

Hope this helps.

Hi Kevin,

Please try the proposed fix at:

  ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/VisADGeometryArray.java

Note this is incorporated in the visad.jar and visad_src-2.0.jar
files at ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/.

If this doesn't fix it, then please send me the test program.

Cheers,
Bill

Thanks for the fix on this.  The fixed UnionSet is allowing me to choose
a ConstantMap color, but when I add an Alpha parameter, it does not
behave as it should.

Using 2 different filled Irregular2DSets, each with its own ConstantMap,
I get this:

However, when I make a UnionSet with the two Irregular2DSets and using
one of the ConstantMaps, I get this:

http://www.cimms.ou.edu/~kmanross/VCPRPE/VisADSamples/kiwaWedges_usetError.gif

Even a UnionSet with a single Irregular2Dset wedge produces the same
produces the latter result.

If you would like, I can send you my test code.
