Thanks, Werner. I appreciate the hard work you do that
keeps Castor improving. I was only stuck on the older
version because of my hacks and Jira issue #1313 not
being worked on, so I had no idea there was a fix in
place. I will certainly try the latest version with
my mappings changed back to the simpler form that I
thought should work originally, and confirm it is all
working as expected now.
