Hello all,

I had I problem that I not sure if it a bug or it supposed to be this way.
First, I created a grib feature type using
<featureCollection name="cfsr_wind" featureType="GRIB" harvest="true" 
path="ncep/cfsr/wind">
        <metadata inherited="true">
          <serviceName>uteis</serviceName>
          <dataType>Grid</dataType>
          <dataFormat>GRIB-2</dataFormat>
        </metadata>
        ...
</featureCollection>
and everything worked great.

To increase the access speed I then created a spacial subset of the global grib 
files and saved everything in netcdf and added to the catalog with
<dataset name="cfsr_wind_nc" ID="ncep/cfsr/windnc" urlPath="ncep/cfsr/windnc">
        <metadata inherited="true">
          <serviceName>uteis</serviceName>
          <dataType>Grid</dataType>
          <dataFormat>NetCDF</dataFormat>
        </metadata>
        ...
</dataset>
Oddly the netcdf data worked perfectly with the opendap protocol but failed 
with the netcdfsubset and wms. I checked the logs and the netcdfsubset was 
trying to use InvDatasetFcGrib despite the data being in netcdf. When I changed 
the ID and urlPath to
<dataset name="cfsr_wind_nc" ID="ncepnc/cfsrnc/windnc" 
urlPath="ncepnc/cfsrnc/windnc">
all the protocols worked. 

Can I have a netcdf and grib feature collection with similar ID/urlPath?

Thank you.
