How to get the reference of the View controller in from Custome controller

Question

Hi friends,
From one of the Custome controllers in my Component,I am raising a popup based on conditions.
I want to subscribe to popup buttons.
Following is the code that I have written.
IF LT_RECEIPTS_T[] IS not INITIAL.
    data lo_window_manager type ref to if_wd_window_manager.
    data lo_api_component  type ref to if_wd_component.
    data lo_window         type ref to if_wd_window.
*BREAK-POINT.
    lo_api_component  = wd_comp_controller->wd_get_api( ).
    lo_window_manager = lo_api_component->get_window_manager( ).
    lo_window         = lo_window_manager->create_window(
                       window_name            = 'W_PERSONALCARDPOPUP'
                       message_display_mode   = if_wd_window=>co_msg_display_mode_selected
                       button_kind            = if_wd_window=>co_buttons_okcancel
                       message_type           = if_wd_window=>co_msg_type_none ).
    lo_window->open( ).
    DATA: view_controller TYPE REF TO if_wd_view_controller.
    view_controller = wd_this->wd_get_api( ).
    CALL METHOD lo_window->subscribe_to_button_event
      EXPORTING
        button      = if_wd_window=>co_button_ok
        action_name = 'OK'
        action_view = view_controller.
as I am In Custome controller,wd_get_api is returing of type if_wd_controller,but the subscribe_to_button_event
requires action_view of data type if_wd_view_controller.
but,my problem is that I can keep the view only Custome controller.
when I pass the 'VIEW_CONTROLLER' variable to method subscribe_to_button_event,I am getting the error  as type missmatch.
Please suggest how I can rectify this error.

Hi Xavier,
You try this
1. Define an attribute in your custom controller to hold your popup window reference for e.g lr_popup of type if_wd_window
2. Store the popup window reference in lr_popup when calling your popup
lo_api_component = wd_comp_controller->wd_get_api( ).
          lo_window_manager = lo_api_component->get_window_manager( ).
          wd_this->lr_popup = lo_window_manager->create_window(
                          window_name = 'W_PERSONALCARDPOPUP'
                          message_display_mode = if_wd_window=>co_msg_display_mode_selected
                          button_kind = if_wd_window=>co_buttons_okcancel
                          message_type = if_wd_window=>co_msg_type_none ).
         wd_this->lr_popup->open( ).
3. Define the custom controller usage in the properties of your popup view
4. In WDDOINIT of your popup view write the following
DATA lr_custom_controller TYPE REF TO ig_<Custom Controller>.
        lr_custom_controller = wd_this->get_<Custom Controller>_ctr( );
        lr_custom_controller->lr_popup->subscribe_to_button_event(
     button = if_wd_window=>co_button_ok
     action_name = 'OK'
     action_view = wd_this->wd_get_api( ) ).
5. Define the event handler for OK in your popup view
