Problem in Popup

Question

Dear All,
I have main 2 views and 2 window
Views  : 1) Main 2) View for Poup
Window : 1) Main 2) Window for Popup (Conatins the View for Popup)
I have One Button on MAIN view on click of which I need to open one popup so for that I have written Below Given code .
data: l_cmp_api           type ref to if_wd_component,
        l_window_manager    type ref to if_wd_window_manager,
        l_api              type ref to if_wd_view_controller.
  l_cmp_api           = wd_comp_controller->wd_get_api( ).
  l_window_manager    = l_cmp_api->get_window_manager( ).
  if wd_this->m_popup1_1 is initial.
    wd_this->m_popup1_1 = l_window_manager->create_window(
             window_name  = 'HEADER_TAX_W'
             TITLE        = 'Header Tax'
             button_kind  = if_wd_window=>CO_BUTTON_OK
    l_api = wd_this->wd_get_api( ).
so I get POPUP with button OK. I want to Register this event so that I can perform some activities. For This I have written below given code in WDDOINIT method of View for Popup .
l_api TYPE REF TO if_wd_view_controller,
l_window_ctlr TYPE REF TO if_wd_window_controller,
l_popup TYPE REF TO if_wd_window.
  l_api = wd_this->wd_get_api( ).
  l_window_ctlr = l_api->get_embedding_window_ctlr( ).
  IF l_window_ctlr IS BOUND.
    l_popup = l_window_ctlr->get_window( ).
    IF l_popup IS BOUND.
      l_popup->subscribe_to_button_event(
      button = if_wd_window=>co_button_ok
      button_text = 'Ok'                                   "#EC *
      action_name = 'OK'
      action_view = l_api
      is_default_button = abap_true ).
    ENDIF .
  ENDIF .
when I execute my application I get below error. PLease let me know where I have done mistake.

Hi ,
I guess you are not defining any button while creating a window using the method create_window and you are trying to register for the same in the do_init method.
Please find the example it will be useful .
method open_popup.
  data: lo_component_api    type ref to if_wd_component,
        lo_window_manager   type ref to if_wd_window_manager,
        lo_popup_window type ref to if_wd_window,
        lv_otr             type string.
  " get window-manager by api
  lo_component_api = wd_this->wd_get_api( ).
  lo_window_manager = lo_component_api->get_window_manager( ).
  lv_otr = cl_wd_utilities=>get_otr_text_by_alias( alias = 'PTRM_WEB_UI/HELLO).
  lo_popup_window = lo_window_manager->create_window(
      window_name          = 'HEADER_TAX_W'
      title                = lv_otr
      close_in_any_case    = abap_false  " cancel action in view
      close_button         = abap_true
      default_button       = if_wd_window=>co_button_ok " Subscribe OK in view
      button_kind     = if_wd_window=>co_buttons_okcancel
lo_popup_window->set_window_size( width = '1000' height = '800' ).
  lo_popup_window->set_remove_on_close( abap_true ).
  lo_popup_window->open( ).
endmethod.
code in WDDOINIT method of View for Popup .
    data lo_api_add_part_view type ref to if_wd_view_controller.
    lo_api_add_part_view = wd_this->wd_get_api( ).
  data lo_wdw_controller type ref to if_wd_window_controller.
  lo_wdw_controller = lo_api_add_part_view->get_embedding_window_ctlr( ).
  data lo_item_popup_window type ref to if_wd_window.
  lo_item_popup_window = lo_wdw_controller->get_window( ).
  data otr_text type string.
  otr_text = cl_wd_utilities=>get_otr_text_by_alias( alias = 'PTRM_WEB_UI/OK' ).
  lo_item_popup_window->subscribe_to_button_event(
    button = if_wd_window=>co_button_ok
    button_text = otr_text
    action_name = 'OK'
    action_view = lo_api_add_part_view
    is_default_button = abap_true
*In the view there define under the actions tab try to create a action named OK and write the code there.
