Forcing PAI processing in the absence of a local event handler

Question

I have a dynpro screen with a splitter container on it.
Each side is populated with a readonly gui object (of cl_gui_textedit and cl_gui_alv_grid).
No special event handling had been enabled for these objects.
I have an application toolbar button defined in the gui status as an application event.
When I click the button, I do not go into PAI processing. (buttons defined as exit commands do hit PAI)
Is there a way to force PAI processing here in the absence of a local event handler, or I must I implement one.   If so, to what event would it respond as I am not hitting a gui control.
( Is there a way to force a set_new_okay_code into it? )
Thanks...

Mike,
  Not sure 100% of what you are asking, however, I'll respond in hopes of a hit.
The ALV Grid allows you to create events in the initialization of the grid.  You build a line for USER_COMMAND and can respond to an event in a FORM you have in your program that
looks something like the following.
FORM user_command
        USING p_ucomm LIKE sy-ucomm
              p_selfield TYPE slis_selfield.
CASE P_UCOMM.
  WHEN .....
  Generally, when I use this routine, I add the buttons to the ALV's Toolbar and respond to it in the USER_COMMAND form.
The routines I've provided here come from a report program, but the concept is the same for the
ALV_GRID OO that you are likely using.
