Markus,
Thanks! Worked like a charm. I had brushed over SMWThingDescription
because it looked like a purely abstract class. Should have noticed
the return value of getQueryString() :-).
No, I'm not in SVN yet...been meaning to, but I keep getting busy with
other stuff...plus my code is not very well documented at the moment
anyway (and this is a generous description). Will let you know when
I'm there.
