End event integrated with leave event in the chat

Hi experts,

I'm trying to put the leave event into the end button to trigger two events by clicking one button.

As i know, both of the events are handled in the method EH_ONFORWARDCALL. Hence i redefined that method and added some code for test. However, the code does not work as expected: the chat was neither wrap up nor ended.

Here's my added code snippet and is added at the end of the method:

          .....

          IF ref_event->get_name( ) = 'InteractionEndRequest'.
                  CREATE OBJECT ref_event2.
                  currentChatId = CL_CRM_IC_MCM_CHAT_PROXY=>GET_CURRENTCHATSESSIONID( ).

          * wrap up event only requires chat id as parameter
                  ref_event2->set_name( 'McmContactWrapUpStarted' ).
                  ref_event2->add_param( name = 'Parameter2' value = currentChatId ). "#EC NOTEXT
                  ref_event_service->raise( ref_event2 ).

           ENDIF.

           ref_event_service->raise( ref_event ).

Could you please help to check what is missing there?

Thanks in advance.
