      By default, the `FilterDataSet` class will iterate over all fields and
use `CastAndCall` on each one to call the subclass' mapping function
with the appropriate array type.

This only works if the array is of a known type. If it is not
`CastAndCall` throws an exception. However, having the entire filter
exception out just because one field cannot be converted does not make
sense. Instead, catch the exception, log a warning, and drop the field.
