Problem in BADI crm_isa_basket_head to pass ct_extension data to ct_text

Question

Hi Experts/Gurus,
I had a problem when i am passing the ct_extension data to ct_text. I need to pass the data of two new fields created in order jsp as extension data. For this i used the BADI method "changehead_before_order" and i had passed this extensoin data from ct_extension to ct_text which can be passed to crm_order_maintain before order. And when i try to get the data using the method gethead_get_data, in this iam calling CRM_ORDER_READ to get the values of IT_TEXT, the b2b webshop is giving an error and asking to logon again.
The below is the code which i have written in both the methods:
METHOD if_ex_crm_isa_basket_head~changehead_before_order.
  DATA : ls_orderadm_h  TYPE LINE OF      crmt_orderadm_h_comt,
         wa_orderadm_h  TYPE LINE OF      crmt_orderadm_h_comt,
         ls_extension   TYPE              crmt_isales_extension,
         wa_extension   TYPE              crmt_isales_extension,
         ls_text        TYPE              crmt_text_comt,
         ls_lines       TYPE              comt_text_lines_t,
         wa_lines       LIKE LINE OF      ls_lines,
         wa_text        LIKE LINE OF      ls_text,
  READ TABLE it_extension INTO wa_extension WITH KEY name = 'ZEXTNSM'.
  wa_text-ref_guid = wa_extension-ref_guid.
*  wa_text-tdobject = 'CRM_ORDERH'.
*  wa_text-tdname = wa_extension-ref_guid.
  wa_text-tdid     = '0001'.
  wa_lines-tdline = wa_extension-value.
  APPEND wa_lines TO ls_lines.
  wa_text-lines = ls_lines.
  INSERT wa_text INTO TABLE ct_text.
  CLEAR wa_text.
  CLEAR wa_lines.
  CLEAR ls_lines.
  READ TABLE it_extension INTO wa_extension WITH KEY name = 'ZEXTNSI'.
  wa_text-ref_guid = wa_extension-ref_guid.
  wa_text-tdid     = '0002'.
  wa_lines-tdline = wa_extension-value.
  APPEND wa_lines TO ls_lines.
  wa_text-lines = ls_lines.
  INSERT wa_text INTO TABLE ct_text.
* ct_text = ls_text.
* append ls_text to CT_TEXT.
ENDMETHOD.
to get the data :
METHOD if_ex_crm_isa_basket_head~gethead_get_data.
  DATA : ls_extension TYPE crmt_isales_extension,
         ls_text        TYPE              crmt_text_comt,
         wa_text        type      CRMT_TEXT_COM,
         ls_lines       TYPE  comt_text_lines_t ,
         wa_lines       type      TLINE,
         ls_basket_head TYPE crmt_isales_baskethead_ui,
         lv_objectid    type CRMT_OBJECT_ID.
  lv_objectid = cs_basket_head-OBJECT_ID.
  if lv_objectid is not initial.
  CALL FUNCTION 'CRM_ORDER_READ'
    EXPORTING
      it_header_guid = cs_basket_head-guid
    IMPORTING
      et_text        = ls_text.
  READ TABLE ls_text INTO wa_text WITH KEY tdid  = 'ZSM'.
*Appending the discount value from the database.
  ls_extension-ref_guid = cs_basket_head-guid.
  ls_extension-name = 'ZEXTNSM'.
    ls_lines[] = wa_text-lines[].
  READ TABLE ls_lines INTO wa_lines INDEX 0.
  ls_extension-value = wa_lines-TDLINE.
  APPEND ls_extension TO ct_extension.
  CLEAR ls_extension.
endif.
ENDMETHOD.
When i put the external break point and checked, in the webshop when i click the update button, in the method changehead_before_order, in the ct_extension table i am getting the values and keys which i have set in the java action. But when i click "order" button, i am not getting anything in ct_extension table which i cannot in turn pass this values to ct_text.
Can you please help me in this regard??
Thanks a lot in Advance!
