problem with GOS view attachment list in SAP Upgrade

Hi,

The view attachment list is working fne in 4.6c for the Z transaction. When I run the same transaction in ECC6, I am getting the 'GOS View Attachment List' icon, but when I click on

this icon, it is given short dump in ECC6 where as in 4.6c it is working fine. It shows the followin dump in ECC6.

SET HANDLER: Reference to handler object cannot be NULL.

The current ABAP program "CL_GOS_TOOLBOX_VIEW===========CP" had to be

terminated because it has

come across a statement that unfortunately cannot be executed.

When specification a handler for an event in the SET HANDLER statement,

the reference "IS_SERVICE-SERVICE" to the handler instance cannot be NULL.

Program CL_GOS_TOOLBOX_VIEW===========CP

Include CL_GOS_TOOLBOX_VIEW===========CM004

Row 69

Module type (METHOD)

Module Name DISPATCH_SERVICE

=============================================

When I click on SET HANDLER statement, control leads to method DISPATCH_SERVICE in class CL_GOS_TOOLBOX_VIEW.

=============================================

I am using the following code.

data: lo_container type ref to cl_gui_custom_container,

ls_object type borident.

ls_object-objtype = 'ZRECON'.

ls_object-objkey = gs_rec_all_scr-reconobj.

case ok_code.

when 'ATTACH'.

call method go_myobject->start_service_direct

exporting

ip_service = 'CREATE_ATTA'

is_object = ls_object

io_container = lo_container.

when 'LIST'.

call method go_myobject->start_service_direct

exporting

ip_service = 'VIEW_ATTA'

is_object = ls_object

exceptions no_object = 1

object_invalid = 2

execution_failed = 3

others = 4.

endcase.

The short dump given at

call method go_myobject->start_service_direct

Thanks a lot.

Zakir.
