How to show messages in a little popup ?

Question

Hello,
Im faced with an issue when I want to show messages in my little popup.
The calling component is BT111H_OPPT.
Whenever I want to show the message in my popup that the mandatory fields are not filled with information the systems only shows them on the view of BT111H_OPPT when I closed my popup.
Ive implemented an own check method for that issue. See the following Code:
IF me->check_mandatory_fields( 'CREATE' ) = abap_true.
    lr_window ?= me->view_manager->get_window_controller( ).
    lr_window->call_outbound_plug( 'CREATE' ).              "#EC NOTEXT
  ELSE.
    DATA: lr_service TYPE REF TO cl_bsp_wd_message_service.
    lr_service = me->view_manager->get_message_service( ).
+   TESTED THAT CODE FIRST TIME, BUT NOTHING APPEARS ANYWHERE!!!!+*
*    CALL METHOD me->messages->add_message
*      EXPORTING
*        condition = co_mandatory_field_empty
*        message   = 'Test'
**        otr_alias =
*        severity  = cl_bsp_messages=>co_severity_error
**        dummy     = me->component_id
**        p1        =
**        p2        =
**        p3        =
**        p4        =
+ SO I TRIED THAT ONE. NOW, THE MESSAGE APPEARS IN THE CALLING COMPONENT!+* 
TRY.
        lr_service->add_message(
        iv_msg_type = 'W'
        iv_msg_id = 'ZICRM'
        iv_msg_number = '050'
        iv_msg_v1 = 'lv_text'
      CATCH cx_bsp_wd_dupl_mess_subscr.
    ENDTRY.
  ENDIF.
THANK you for an answer...

Hi Marcus,
try to use the following method as you create the popup in the calling view controller:
<your popup ref>->set_display_mode( iv_mode = if_bsp_wd_popup=>c_display_mode_surrounded ).
Best Regards,
Michael
