How to handle the button "cancel" in a dialog box for displaying views?

Question

Hello!
I ve a question about handling the cancel button in a dialog box for displaying views.
I ve already implemented the dialog box by using the following code:
METHOD eh_onnewqact.
  DATA stitle TYPE string.
  IF m_popup IS BOUND.
    stitle = cl_bsp_runtime=>get_otr_text( alias = 'ZCC_ICRM/NEW_TASK' )."cl_wd_utilities=>get_otr_text_by_alias( 'ZCC_ICRM/NEW_TASK' ).
    m_popup = comp_controller->window_manager->create_popup(
      iv_interface_view_name = 'ZCC_POPUP_NEWBT/NewQActWindow'
      iv_usage_name = 'CUNewQAct'
      iv_title = stitle
    CALL METHOD m_popup->set_on_close_event
      EXPORTING
        iv_view       = me
        iv_event_name = 'NEWQACT_POPUP_CLOSED'.
  ENDIF.
  m_popup->open( ).
ENDMETHOD.
My dialog box consists two buttons - cancel and create.
The cancel buttons should close the popup and the create button should create an entity of a specified object. but let us come to the cancel button. I did´nt find any information about implementing an cancel button. So, how should I implement it? I thougt
me->close( ). But that didnt works!
Could u give me further information about that, because my cancel event-handler is empty?
method EH_ONCANCEL_QACT.
endmethod.
After that I would know how my calling view could know that the user pushes the Create Button and how the data of 2 inputfields of the dialog box finds their way to the calling view in order to process this data there?
Thank you very much!

Hi Michael,
thank you for your advice! This problem is solved...
...but I have another issue. Ive implemented 2 editable fields in my popup. The user should fill that fields with context and that context should be processed in the calling view of my popup.
My question is how to transfer these information from my popup to my calling view or method?
I tried the following...
      lv_context_node ?= m_popup->get_context_node( 'QUICKACT' ).
      IF lv_context_node IS NOT INITIAL.
        lv_text = lv_context_node->get_date( attribute_path = '' ).
      ENDIF.
But it doesnt work! The context node object is always empty/initial.
Thank you!
PS: Another possibility could be that the object / node of the calling view is transferred to the pop-up in order to process it there.
