Error message for radiobuttongroup using report_attribute_error_message

Question

Hi,
We are displaying error message on the submit button of a form in web dynpro abap application. We have different UI elements in the form which are mandatory to enter by the user.So we are using 'CALL METHOD lo_message_manager->report_attribute_error_message' method to display error.
When user click on the error message control will go the UI field which is caused for error.
This works fine for INPUT,DROPDOWNBYKEY,TEXTEDIT,RADIOBUTTON UI elements.
But error link is not working for RADIOBUTTONGROUPBYKEY/RADIOBUTTONGROUPBYINDEX ui elements.
Is this problem is with WEB DYNPRO ABAP or am i missing any property settings. Does SAP Web Dynpro ABAP provide this functionality for RADIOBUTTONGROUPBYKEY/RADIOBUTTONGROUPBYINDEX?
Please help us to resolve the problem.
Below attached written code for reference.
CASE lo_action->name. WHEN 'SUBMIT'.
IF lv_radio IS INITIAL.
*    REPORT message
   call method lo_message_manager->report_attribute_error_message
     exporting
       message_text              = 'Please select something from radio button grp by key.'
       element                   =  lo_el_radio_node
       attribute_name            = `RADIO`
*        params                    =
*        msg_user_data             =
*        is_permanent              = ABAP_FALSE
*        scope_permanent_msg       = CO_MSG_SCOPE_CTXT_ELEMENT
*        msg_index                 =
*        cancel_navigation         =
*        is_validation_independent = ABAP_FALSE
  ENDIF.
    IF lv_text IS INITIAL.

Hi Smitha
You declare as below :
*---- SELECTION-SCREEN
SELECTION-SCREEN BEGIN OF BLOCK b1.
SELECT-OPTIONS : s_werks FOR vbap-werks .                 "Plant
SELECTION-SCREEN END OF BLOCK b1.
*Selection Screen validation
AT SELECTION-SCREEN .
  IF s_werks-low IS NOT INITIAL.
    SELECT SINGLE werks            "Plant
    FROM t001w
    INTO s_werks-low
    WHERE werks = s_werks-low
    and werks in ( '2000','3000','4000' ).
    IF sy-subrc NE 0.
      MESSAGE e000 WITH text-t48.
    ENDIF.
  ENDIF.
if its a parameter just replace s_werks as p_werks
