Am unable to determine is a variable contains a Null value, since the
if will always evaluate to a not Null condition.   Have verified in the
debugger
that the variable selectedMeter does in fact contain a null value, but the
if will always evaluate to a not Null condition.   This is my code:

CSpValue selectedMeter = getDisplayFieldValue ("cbMeters"); 
if (selectedMeter.isNull())

any ideas as to what the problem is?  any help on this is very much
appreciated.  thanks.
