Hello

An instance method of a class has been called but the reference variable did not contain any instance, e.g.:


DATA: go_myclass    TYPE REF TO zcl_myclass.  " has instance method display

START-OF-SELECTION.

  CALL METHOD go_myclass->display( ).  " error because go_myclass not yet instantiated

" Replaced by:
  CREATE OBJECT go_myclass.
  CALL METHOD go_myclass->display( ).  " Now it works

" Or:

  CHECK ( go_myclass IS BOUND ).  " available on release >= 6.20
  CALL METHOD go_myclass->display( ).

Regards

Uwe
