LinearNDSet

Hi,

Before I bang my head against the wall any more on this, does anyone
know why I might be having a problem using a LinearNDSet for one field
and using visad.data.netcdf.Plain.open to create another?

I have terrain: (Longitude, Latitude) -> Elevation  read from a netCDF
file.

I have model data: (Longitude, Latitude, Altitude, Time) -> Temperature
for which I construct a LinearNDSet for the 4D domain.

If I make the terrain data first, when I make the Set I get:

java.lang.reflect.InvocationTargetException: visad.TypeException: Set:
Type must be SetType, RealTupleType or RealType
        at visad.Set.adjustType(Set.java:198)
        at visad.LinearNDSet.get_linear1d_array(LinearNDSet.java:136)
        at visad.LinearNDSet.<init>(LinearNDSet.java:56)

        at vmet.VMETServer.start(VMETServer.java:67)
        at vmet.VMETControl.main(VMETControl.java:50)

If I make the Set first, when I make the terrain I get:

Couldn't initialize class QuantityDBManager
java.lang.reflect.InvocationTargetException:
java.lang.NullPointerException

        at vmet.VMETServer.start(VMETServer.java:67)
        at vmet.VMETControl.main(VMETControl.java:50)

Either one works fine when the other is not around.

Any ideas?

Thanks,
Doug
