Popup Window issue

Question

Hi all,
      I need to show a popup when feature dated records exists. For that on the Save action of the user I am checking the feature dated records and showing a popup.
ISSUE:
I am calling this popup in onSAVE action.  Based on the user ok or cancel I need to perform some code in the same action. But the issue is the code below the popup is being run even before the popup is displayed and after user clicks OK or Cancel the cursor does not comeback to onSave action at all.
How to do in this scenario?
Code:
lo_window         = lo_window_manager->create_window(
                   window_name            = 'ZSDRPOPUP'
                  title                  = 'Feature Dated Records Exists.'
                 close_in_any_case      = abap_true
                   message_display_mode   = if_wd_window=>co_msg_display_mode_selected
                 close_button           = abap_true
                   button_kind            = if_wd_window=>CO_BUTTONS_OKCANCEL
                   message_type           = if_wd_window=>co_msg_type_none
                   default_button         = if_wd_window=>co_button_ok
lo_window->subscribe_to_button_event(
button = if_wd_window=>CO_BUTTON_OK
button_text = 'Overwrite'
action_name = 'SUBMIT'
action_view =   lo_view_controller ).
lo_window->subscribe_to_button_event(
button = if_wd_window=>CO_BUTTON_CANCEL
button_text = 'Cancel'
action_name = 'CANCEL'
action_view =  lo_view_controller ).
lo_window->open( ).

Popups are not synchronous in Web Dynpro. Therefore it is normal for processing to continue (and the phase model to complete) before the popup is even displayed.  That is why you register events for the buttons that are pressed within the popup.  It is in the event handlers of these events that you will continue your processing.  You probably need to be more modular with your code so that the actual save logic can be called from within the button OK event handler of the popup as well.
