CL_GUI_TEXTEDIT refresh problem

Dear Gurus ,

I made a custom screen that has 3 texteditor controls . The screen works fine but the one problem that i have is the below :

I have 2 kind of users: Full user - Particiopant user

When i load the screen at the first time all the controls are editable .

When i choose the the participant user i want the texteditor controls to be in readonly mode.

So i do the following :

IF PARTICIPANTS = 'X'.

    CALL METHOD G_EDITOR_1->SET_READONLY_MODE
        EXPORTING
          READONLY_MODE          = '1'
        EXCEPTIONS
          ERROR_CNTL_CALL_METHOD = 1
          INVALID_PARAMETER      = 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.

when i change the user to full can't change !!!!!!

Look the problem in steps:

1. load the screen in editable mode

2. changing the controls to readonly ok

3. changing to editble false

Only one time i can change the screen control !!!!

look my code ...
