ABPA UI--Triggering PAI manually [@more@]

Sometime, when you work with ABAP OO GUI objects like ALV grid, tree, HTML control, 
etc, you want to trigger the PAI with a specific OKCODE without any interraction from 
the user. This is quite simple, you just have to call this small method :
* Execute PAI of actual screen to update ALV
  CALL METHOD cl_gui_cfw=>set_new_ok_code
    EXPORTING
      new_code = 'DUMMY'.  "<<==-- Here you put the OKCODE that you want to dispatch

* A flush is required to trigger the refresh 
  CALL METHOD cl_gui_cfw=>flush.
