Hi all,
I'm attempting to do an NcML "union" aggregation of several variables
from a forecast model that are contained in separate remote OPeNDAP
locations. While this works in TDS 4.2 (and Tools UI 4.2), I'm getting
an error in TDS 4.3.16 (and Tools UI 4.3). Below are the details.
Perhaps this is related to the recent "joinExisting" remote
aggregation problem that Roland Schweitzer reported in TDS 4.3 here:
https://www.unidata.ucar.edu/mailing_lists/archives/thredds/2013/msg00093.html.
rolands problem was fixed
I have already tried clearing the cache and restarting Tomcat as was
suggested in that chain: also did not solve the problem in my case,
either. Thanks in advance for your help on this.
Cheers,
John Maurer

get a release out for another week.
thanks for reporting!
