Clear Custom messages when End Button is clicked on IC Screen in CRM 6.0

Question

Dear CRM Experts,
I had a requirement to give out a custom info message based on some conditions when a service ticket is created. I could get this accomplished by implementing the BAdI ORDER_SAVE and adding a message using the method ADD_MESSAGE in class CL_BSP_WD_MESSAGE_SERVICE. I could get the custom message as well as the standard message that the Transaction XXXX is saved.
However, when I click the End button on the interaction center web ui, the standard message gets cleared off, but my custom message still shows up. Can anyone advice where I should be clearing the custom message log when the end button is clicked?
Regards,
Suneetha

The thing is he "old" / standard code isn't executed. I tried using a break point there to see if it will be executed, but it didn't stop at all .
Here is the code.
IF param1-value = 'InteractionEndRequest'.
*    BREAK-POINT.
     DATA:           lr_messagetab        TYPE         crmt_genil_mess_cont_tab,
                         lr_core              TYPE REF TO  cl_crm_bol_core,
                         lr_message_container TYPE REF TO  if_genil_message_container,
                         lr_mess_core         TYPE REF TO  cl_crm_genil_mess_cont_manager.
     lr_core        = cl_crm_bol_core=>get_instance( ).
     lr_mess_core   = lr_core->get_message_cont_manager( ).
     lr_mess_core->get_all_message_containers(
                 IMPORTING et_result =  lr_messagetab ).
     LOOP AT lr_messagetab INTO lr_message_container.
       lr_message_container->delete_messages( ).
     ENDLOOP.
   ENDIF.
