Re: Multiple instances of VisAD class

Hi Megan,

Glad to hear that your application is basically working.

Try replacing all statements like:

  RealType type = new RealType(name);

with statements:

  RealType type = RealType.getRealType(name);

in your application.  There is an argument signature of
getRealType() to match every RealType() constructor
signature.  If the RealType has already been constructed,
then getRealType() returns that rather than constructing
a new one.
