Creating object type conflict dump

Former Member — Wed, 05 Mar 2008 11:19:54 GMT

Hi All,

I have an interface zintf_1. I getting the list of classes that implemented the zintf_1.

There are some cases where the class wont have implemented the interface.

ZDEMO_AA class has not implemented the interface zintf_1.

data: lr_intf_1 type ref to zintf_1,

lv_clsname type SEOCLSNAME.

lv_clsname = 'ZDEMO_AAA'.

try.

create object lr_intf_1 type (lv_clsname).

catch cx_sy_create_object_error.

.....

endtry.

In that case i m getting the dump "Type conflict with allocation of References".

Please help me to resolve the issue.

thanks

I'm assuming that you're trying to trap the case the class lv_clsname doesn't actually implement the interface.

Well, the interface not being there is NOT a catchable error. So you have to find out whether the interface is implemented first.

DATA: lr_intf_1  TYPE REF TO zintf_1,
      lv_clsname TYPE seoclsname,
      lr_object  TYPE REF TO cl_oo_class,
      lt_intf    TYPE seo_relkeys.

lv_clsname = 'ZDEMO_AAA'.

lr_object ?= cl_oo_object=>get_instance( lv_clsname ).
lt_intf = lr_object->get_implemented_interfaces( ).

READ TABLE lt_intf TRANSPORTING NO FIELDS WITH KEY refclsname = 'ZINTF_1'.
IF sy-subrc IS INITIAL.
  CREATE OBJECT lr_intf_1
    TYPE
      (lv_clsname).
  WRITE: 'it worked'.
ELSE.
  WRITE / 'it failed'.
ENDIF.
