Using ADD_CONTROL of CL_GUI_SPLITTER_CONTAINER

Question

Hi Forum,
I would like to add (and remove) the controls of a splitter container grid by program. So I think the methods ADD_CONTROL and REMOVE_CONTROL should be the right choice.
The problem is, that the use of ADD_CONTROL does not work for me. There is no error, but I cannot see the control either...?!?
For example, I would like to throw a splitter_container (inner_split) into another splitter_container (outer_split). First I post a working example without ADD_CONTROL...
* the custom_container named is quite generated...
    DATA:
      outer_split        TYPE REF TO CL_GUI_SPLITTER_CONTAINER,
      inner_split        TYPE REF TO CL_GUI_SPLITTER_CONTAINER,
      gui_cont_1_1   type ref to cl_gui_container.
*     the outer splitter
      CREATE OBJECT outer_split
        EXPORTING
          parent            = custom_container
          rows              = 3
          columns           = 1
        EXCEPTIONS
          cntl_error        = 1
          cntl_system_error = 2
          others            = 3.
      IF sy-subrc <> 0.
        exit.
      ENDIF.
* getting the cell I would like to throw the inner_split into...
    CALL METHOD outer_split->GET_CONTAINER
      EXPORTING
        ROW       = 1
        COLUMN    = 1
      RECEIVING
        CONTAINER = gui_cont_1_1.
* now I can create the inner_split
      CREATE OBJECT inner_split
        EXPORTING
          parent            = gui_cont_1_1
          rows              = 1
          columns           = 2
        EXCEPTIONS
          cntl_error        = 1
          cntl_system_error = 2
          others            = 3.
      IF sy-subrc <> 0.
        exit.
      ENDIF.
This code works fine, but I have to know the parent of inner_split by creation. So I would like to code something like...
* the custom_container named is quite generated...
    DATA:
      outer_split        TYPE REF TO CL_GUI_SPLITTER_CONTAINER,
      inner_split        TYPE REF TO CL_GUI_SPLITTER_CONTAINER.
*     the outer splitter
      CREATE OBJECT outer_split
        EXPORTING
          parent            = custom_container
          rows              = 3
          columns           = 1
        EXCEPTIONS
          cntl_error        = 1
          cntl_system_error = 2
          others            = 3.
      IF sy-subrc <> 0.
        exit.
      ENDIF.
*  inner_split
      CREATE OBJECT inner_split
        EXPORTING
          parent            = outer_split
          rows              = 1
          columns           = 2
        EXCEPTIONS
          cntl_error        = 1
          cntl_system_error = 2
          others            = 3.
      IF sy-subrc <> 0.
        exit.
      ENDIF.
* use of add_control
          CALL METHOD outer_splitt->ADD_CONTROL
            EXPORTING
              ROW       = 1
              COLUMN    = 1
              control   = inner_split.
          inner_split->set_visible( visible = 'X' ).
After running the code I cannot see the inner_split? I think the problem could be, that inner_split needs a parent while creation, but I do not really know what to handle here...?
Thanks for response,
Dennis

Hi,
Though described as released methods in the SAP library, these 2 methods are "flagged" obsolete in their description. When I use them in release basis 7.0, I have a popup at SAP GUI (since Release I don't know) side "Error while setting client site! No warranty for further processing! NO WARRANTY FOR ...)|https://service.sap.com/sap/support/notes/653100]
Workaround is to set a null size (set_column_width or set_row_height)
