Hi all..

Need some help here. Actually I am new to ABAP programming. I want to ask some question regarding ABAP language. I want to transfer text from the custom container into the table control. The first value can be transfered. But when i try for second time the custom container cannot transfer the value.

Below is the code after the button been pressed.

CALL METHOD TEXT_EDITOR->GET_TEXTSTREAM
*         EXPORTING
*             ONLY_WHEN_MODIFIED     = CL_GUI_TEXTEDIT=>TRUE
          IMPORTING
              TEXT                   = TEXT
*             IS_MODIFIED            =
          EXCEPTIONS
              ERROR_CNTL_CALL_METHOD = 1
              NOT_SUPPORTED_BY_GUI   = 2
              OTHERS                 = 3.

      IF SY-SUBRC <> 0.
        MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
                   WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      ENDIF.

      CALL METHOD CL_GUI_CFW=>FLUSH
        EXCEPTIONS
          CNTL_SYSTEM_ERROR = 1
          CNTL_ERROR        = 2
          OTHERS            = 3.
      MESSAGE TEXT TYPE 'I'.


     MOVE TEXT TO  WA_ZMMSSKILL-ZSKILL.

    MOVE-CORRESPONDING WA_ZMMSSKILL TO G_TABLE1_ITAB.
    APPEND G_TABLE1_ITAB.
    REFRESH CONTROL 'TABLE1' FROM SCREEN '0100'.

Thank you for viewing this problem and try to help me in advance. :)
