Somewhere along the way, a CSpNull (subclass of CSpValue) was passed as an
argument to a method that required a CSpValue, and stored away in a member
variable that is defined as a CSpValue.
Later, the class needs to convert the CSpValue to a 'long' (numeric) value,
so it calls longValue() on the member variable. Theoretically every
CSpValue subclass implements longValue(), but, actually, there is a
CSpValue-level implementation that simply displays the below message, and
then it is optional whether or not each concrete subclass overrides it.
Apparently, CSpNull does not.
Perhaps a CSpNull was passed to a 'setValue' call on a dataobject for a
data column defined as 'long' in the db schema. At the time of the next
insert or update, the dataobject, in the course of constructing SQL for the
database call, would call 'longValue' on the CSpNull.
