+.. note:: If you are using the Form Validation class, you must always specify a rule for your field,
+ even if empty, in order for the set_*() functions to work. This is because if a Form Validation object
+ is defined, the control for set_*() is handed over to a method of the class instead of the generic helper
+ function.
