Re: visad.TypeException

Hi Nash'at,

First, to solve your problem, replace code:
  new RealType(...)   and   new TextType(...)
  RealType.getRealType(...)   and   TextType.getTextType(...)

VisAD maintains a static list of ScalarTypes, so once you create
a ScalarType you cannot create one with the same name again, but
you can reuse the original one.

Secondly, I would recommend against using a Java3D display inside
a JInternalFrame.  You'll notice the heavyweight Java3D panel
will draw on top of parts of the JInternalFrame, and currently
there is no workaround to this problem.  It's probably easier to
just use separate JFrames.
