Hi,

In README.developer it says the general rules:
      static hf_register_info hf[] = {
              { &hf_PROTOABBREV_FIELDABBREV,
                      { "FIELDNAME", "PROTOABBREV.FIELDABBREV",
                      FIELDTYPE, FIELDBASE, FIELDCONVERT, BITMASK,
                      "FIELDDESCR", HFILL }
              }
      };

In proto.h the FIELDBASE declared as enum:
typedef enum {
      BASE_NONE,      /**< none */
      BASE_DEC,       /**< decimal */
      BASE_HEX,       /**< hexadecimal */
      BASE_OCT,       /**< octal */
      BASE_DEC_HEX,   /**< decimal (hexadecimal) */
      BASE_HEX_DEC,   /**< hexadecimal (decimal) */
      BASE_CUSTOM     /**< call custom routine (in ->strings) to format */
} base_display_e;

If you are using FT_BOOLEAN, it's no longer BASE_* enum, but number of field bits.

From proto.h:
  int display;        /**< one of BASE_, or number of field bits for FT_BOOLEAN */


If you have real boolean (0/1) field, I think you need to pass 1 there :)
