Starting a GOS-Service direct

Question

Hello,
In my application i´m using the generic object services by starting the service "view attachment-list" directly (in a 4.6C System).
For the first call the service works fine, but how should i do by changing the published object? In this case i need e refresh of the alv because of the changed object - but i can´t find a method to do this! Also i can´t find a method to destroy the alv-control...
Maybe you can help me!
Thanks,
Christof
The program-steps look like this:
data:     ref_cust_gos      type ref to cl_gui_custom_container,
     ref_gos_manager type ref to cl_gos_manager,
     wa_object     type borident.
CREATE OBJECT ref_cust_gos
  EXPORTING
    container_name              = 'CUST_CONT'.
CREATE OBJECT ref_gos_manager.
wa_object-objkey = '1'.          
wa_object-objtype = 'ZTEST'.     
CALL METHOD ref_gos_manager->start_service_direct
  EXPORTING
    ip_service       = 'VIEW_ATTA'
    is_object        = wa_object
    io_container     = ref_cust_gos  
CALL METHOD ref_gos_manager->unpublish.
wa_object-objkey = '2'.          
wa_object-objtype = 'ZTEST'.     
CALL METHOD ref_gos_manager->start_service_direct
  EXPORTING
    ip_service       = 'VIEW_ATTA'
    is_object        = wa_object
    io_container     = ref_cust_gos

Hi Raja,
the coding in my program look like this:
data:
ref_cust_cont   type ref to cl_gui_custom_container,
ref_gos_manager type ref to cl_gos_manager,
wa_object       type borident.
if ref_cust_cont is initial.
  custom container
    CREATE OBJECT ref_cust_cont
    EXPORTING
    container_name = 'CUST_CONT'.
  GOS-manager
    CREATE OBJECT ref_gos_manager.   
endif.
wa_object-objkey  = lv_key.   "1
wa_object-objtype = 'ZTEST'.
starting the service direct
    CALL METHOD ref_gos_manager->start_service_direct
      EXPORTING
      ip_service = 'VIEW_ATTA'
      is_object = wa_object
      io_container = ref_cust_cont
    EXCEPTIONS
      no_object        = 1
      object_invalid   = 2
      execution_failed = 3
      OTHERS           = 4
Now the attachment-list of the new object '2' (objectkey) should be shown... so the same procedure starts again:
wa_object-objkey  = lv_key.   "2
wa_object-objtype = 'ZTEST'.
starting the service direct
    CALL METHOD ref_gos_manager->start_service_direct
      EXPORTING
      ip_service = 'VIEW_ATTA'
      is_object = wa_object
      io_container = ref_cust_cont
    EXCEPTIONS
      no_object        = 1
      object_invalid   = 2
      execution_failed = 3
      OTHERS           = 4
Now the ALV should show the attachment list of object "2" but it doesn´t. It also doesn´t help when i´m using the method PUBLICATION_CHANGED after the method-call START_SERVICE_DIRECT!
May be you have a code sample for me?!
