Error: While Opening a Custom view- Action &OBJECT_ID& does not exist

Question

Hi Experts,
On the click of button, I am creating a window and opening as follows:
  wd_comp_controller->go_window         = lo_window_manager->create_window(
                      window_name            = 'ZW_CERTIFICATION_POP'
                      title                  = lv_pop_title
                      close_in_any_case      = abap_false
                      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
I have written following code in INIT method of View to Subscribe events but it is dumping with the Error "Action &OBJECT_ID& does not exist ".
DATA lv_ok     type string.
DATA lv_cancel type string.
DATA lo_popup  TYPE REF TO if_wd_window.
DATA lo_view   TYPE REF TO if_wd_view_controller.
DATA lo_window_ctlr type ref to if_wd_window_controller.
register button events
    lo_view = wd_this->wd_get_api( ).
    lo_window_ctlr = lo_view->get_embedding_window_ctlr( ).
    wd_comp_controller->go_window = lo_window_ctlr->get_window( ).
    lv_ok = cl_wd_utilities=>get_otr_text_by_alias( alias = 'PAOC_RCF_UI/OK' ).
    wd_comp_controller->go_window->subscribe_to_button_event(
                   button            = if_wd_window=>co_button_ok
                   button_text       = lv_ok
                   action_name       = 'OK'
                   action_view       = lo_view
                   is_default_button = abap_true
    lv_cancel = cl_wd_utilities=>get_otr_text_by_alias( alias = 'PAOC_RCF_UI/CANCEL' ).
               wd_comp_controller->go_window->subscribe_to_button_event(
                  button            = if_wd_window=>co_button_cancel
                  button_text       = lv_cancel
                  action_name       = 'CANCEL'
                  action_view       = lo_view
                  is_default_button = abap_true
How to solve this exception causing application to dump.
Thanks

Hi Depeshn,
I have written following code in INIT method of View
I think you have writen code containg subscribe_to_button_event method in the INIT method of the pop up view. But actually you should write that code where you are generating the pop up window. i.e in the ONACTION method of the button (which when clicked generates the pop up window.)
It should be something like this:
" This whole code should come in the event handler of the button.
wd_comp_controller->go_window = lo_window_manager->create_window(
window_name = 'ZW_CERTIFICATION_POP'
title = lv_pop_title
close_in_any_case = abap_false
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
DATA lv_ok type string.
DATA lv_cancel type string.
DATA lo_popup TYPE REF TO if_wd_window.
DATA lo_view TYPE REF TO if_wd_view_controller.
DATA lo_window_ctlr type ref to if_wd_window_controller.
* register button events
lo_view = wd_this->wd_get_api( ).
lo_window_ctlr = lo_view->get_embedding_window_ctlr( ).
wd_comp_controller->go_window = lo_window_ctlr->get_window( ).
lv_ok = cl_wd_utilities=>get_otr_text_by_alias( alias = 'PAOC_RCF_UI/OK' ).
wd_comp_controller->go_window->subscribe_to_button_event(
button = if_wd_window=>co_button_ok
button_text = lv_ok
action_name = 'OK'
action_view = lo_view
is_default_button = abap_true
lv_cancel = cl_wd_utilities=>get_otr_text_by_alias( alias = 'PAOC_RCF_UI/CANCEL' ).
wd_comp_controller->go_window->subscribe_to_button_event(
button = if_wd_window=>co_button_cancel
button_text = lv_cancel
action_name = 'CANCEL'
action_view = lo_view
is_default_button = abap_true
I hope it helps.
