Re: NetCDF Subset Service error

Hi Steve:

this should be fixed in TDS version 4.2.1 (2010-12-01 20:28:24) and CDM version 4.2.20101130.2222

let me know if you see any problems

John,

I am seeing this in the logs, but this shouldn't matter unless I'm doing
a FMRC, right?

Hi Steve: it looks like a null-valued attribute. I couldnt get at the
sample file to verify this, however, is www1.ncdc.noaa.gov  public?

Hi John,

I'm getting this error when trying to use the NetCDF Subset Service in
the TDS 4.2.  I'm not sure if this error exists in older versions.  I've
been unable to reproduce using CDM grid access with ToolsUI or with
custom code.

I don't see any 'null' attributes when doing ncdumps or grid views in
ToolsUI.  There is no time dimension, but we are using NcML Aggregation
with dateFormatMark to add it later.  We are getting the same error with
the NcML aggregation as well.  Unfortunately, the error doesn't show
which attribute is 'null'.  I was going to look in the source, but
figured I'd ask first.

Sample file is here:

Thanks!
Steve
