CALLSUPER(_SELF_, '_validate');

Details

_validate is not valid unless you have subclassed a text entry field and overridden the supplied _validate method with your own. _validate is called automatically when a field is modified.

Example

_validate adds customized validation to the default validation:

VALIDATE:
   method;
         /*  turn off error flags   */
      call send(_self_,'_erroroff_');
         /*  do supplied validation */
      call super(_self_,'_validate_');
         /*  get field value        */
      call send(_self_,'_get_value_',nval);
         /*  do custom validation   */
      if (nval>goodval) then
         call super(_self_,'_erroron_');
   endmethod;
