I am trying to execute "retrieve unique" queries on classes which have a
boolean attribute but I keep receiving the following warning

NOTICE:Oct  3 12:53:06:there is no operator < for types bool and bool
NOTICE:Oct  3 12:53:06:You will either have to retype this query using an
NOTICE:Oct  3 12:53:06:explicit cast, or you will have to define the operator
WARN:Oct  3 12:53:06:< for bool and bool using DEFINE OPERATOR
  
What do I need to do to make this work properly?

Thanks,
Robert
