Re: Different icons for the files with same mime and different extensions.

You probably need to provide your own editor TopComponent or something
similar - stuff that's normally provided automatically for you.  Or fish
around in TopComponent.getRegistry(), find the editor component for your
file and change it after you're *sure* it's been opened (which may happen
asynchronously) - you should be able to get the DataObject from it's lookup
and see if it's yours.

That said, I too question the design here - why two extensions for the same
data format?  Something smells badly thought-out here.  What does the
extension signify?
