Prolog!  I don't even remember its purpose!?

It has been some time for me too, but I think what is wrong is that
you have something like this:

        f: @file;
        listBoxFile: @f;

where f is already an instantiated version of file and (f) can not be
subpatterned.  If you make f into a pattern by removing the "@" your
code should work, me thinks.
