Re: netCDF file works in v2.0 but not v2.1

Hi Bill-

Could you send a note to support-idv@xxxxxxxxxxxxxxxx with
a pointer to the file on an http or ftp server (or if it's
small, attach it to the message).  We recently had another
inquiry about a similar problem and would like to check
into this further.   For the other user, it appeared to
be a problem in the underlying netCDF library and using the
latest stable beta worked.  You could get that at:

http://www.unidata.ucar.edu/software/idv/release/stable

and try it if you are daring. ;-)

Hi,

I just upgraded from v2.0 of IDV to v2.1. I have a netCDF file that works in
v2.0, but when I use it in v2.1 it does not. I am able to open the file, but
when I choose a variable for a contour plot I get error:
    An error has occurred:
    Couldn¹t get data
    java.lang.NullPointerException
This gets followed by another error dialog box saying ³Unable to load field:
T2². The sequence gets repeated twice. Below is the header output for the
file if that helps anybody decipher this one.

Thanks for your help.
