How to get Focused UI element on the Window in 7.01

Question

HI,
  We were on 7.00 and recently upgraded to 7.01. we have a problem with the upgrade.. The window object no more holds the Focus . Here is the code ...  lo_curr_window->focus is blank all the  times.. This was working fine till 7.00 and now it stopped working..
data:lo_window_manager      type ref to if_wd_window_manager,
        lo_api_component       type ref to if_wd_component.
  data: lo_clnt_appl type ref to cl_wdr_client_component,"CL_WDR_CLIENT_APPLICATION,
          ls_view_mgrs type wdr_viewman_line,
          lo_curr_window type ref to cl_wdr_window,
          ls_focus type wdr_focus,
          lo_uielem type ref to cl_wd_uielement,
          lv_path type string,
          lo_selected_elem type ref to if_wd_context_element,
          lt_strtab type table of string,
          lv_colname type string,
          lv_tablen type int4.
  lo_api_component  = wd_comp_controller->wd_get_api( ).
  lo_window_manager = lo_api_component->get_window_manager( ).
  lo_clnt_appl ?= lo_window_manager.
  read table lo_clnt_appl->view_managers_for_window
              into ls_view_mgrs with key name = `ZWD_TEST`.
  if sy-subrc = 0.
  get the window in which this interface view is embedded
    lo_curr_window = ls_view_mgrs-view_manager->get_window_recursive( ).
    if lo_curr_window is initial.
      lo_curr_window = wdr_task=>application->application_window->get_active_modal_window( ).
    endif.
    if lo_curr_window is not initial.
      ls_focus = lo_curr_window->focus.
      lo_uielem ?= ls_focus-view_element.
   endif.
  endif.
Thanks
Mahesh

You seem to be utlitzing SAP internal APIs - so a change in behaviour between releases certainly seems possible. Refer to the online help to find out which APIs are safe to use:

What exactly are you trying to acomplish?  From your code you seem to be trying to get the UI element that has the current focus. Is that correct?  To what purpose?
Perhaps you should review the online help section on Focus Handling:
