Why my OOPs Event is not working in this simple code example ?

[Former Member]

In this code below , my event 'Positive ' is not working (not triggered when result is positive), but the 'Negative'  one is working.

method SUB.

      RESULT = NUM1 - NUM2.

      IF RESULT <= 0 .

        RAISE EVENT NEGATIVE.

      ELSE.

        RAISE EVENT POSITIVE.

      ENDIF.

endmethod.

----------------------------------------------------------

My code in se38:

PARAMETERS : INT1 TYPE I,

                           INT2 TYPE I.

DATA               : RES  TYPE I.

DATA       : OBJ TYPE REF TO myclass.

CREATE OBJECT OBJ.

SET HANDLER OBJ->NEGATIVE_HANDLER FOR OBJ.

CALL METHOD OBJ->SUB

   EXPORTING

     NUM1   = INT1

     NUM2   = INT2

   IMPORTING

     RESULT = RES

     .

   WRITE😕 RES.

Is there a reason why ?

Thank you.

Hi Sami,

Did you define event handler class for your class. Also I did not see the SET HANDLER command for raising event . Also events has to be there in that class.

Please check again.

Thanks,

Hi Santosh,

Thank you for your reply. Actually you are right , I forgot to add:

SET HANDLER OBJ->POSITIVE_HANDLER FOR OBJ. as I did for the Negative event.My

bad. That is the reason it was not triggered.

Cheers.
