Hi again Heiko,
I folded in some changes from the current ncWMS code that has fixed the
problem. It will be in TDS 4.1.3 which I'm planning to release sometime
next week. I've also made a current snapshot available on our FTP site
if you want to try it out before the full release. The snapshot is
available at:
ftp://ftp.unidata.ucar.edu/pub/thredds/4.1/Snapshot/
Cheers,
Ethan
