How to make the text_field to editable in the adobe document?

Question

Hi, expert,
I meet a problem when I develop a WDA. I hope to get your help. Thanks a lot. The following is my action:
Action:
1. I am using "Text Field" control rather "Text" Control in the pfd form by transfer code "sfp". I make sure in Object Palette under value tab type is : user entered - optional in the layout tab in the pfd form. The textfield is editable in the PDF preview.
2. Add the pdf forms to webdynpro application and set "sss" to the inputfield("Text Field") through context in the WDA.
3. Run the WDA. In the IE, I found the textfield in the PDF is not editable. How can I make the  textfield to editable?
Whether I need  change the code or others to make text_field to editable?
Do you give me some hints? Thank you very much.
The following is my code in the WDA:
method WDDOMODIFYVIEW .
********Make INTERACTIVE_FORM to editable。******
data:
lr_interactive_form type ref to cl_wd_interactive_form,
lr_method_handler type ref to if_wd_iactive_form_method_hndl.
lr_interactive_form ?= view->get_element( 'INTERACTIVE_FORM' ).
lr_method_handler ?= lr_interactive_form->_method_handler.
lr_method_handler->set_legacy_editing_enabled( abap_true ).
data:
Node_Zz_00_Test_Form_000 type ref to If_Wd_Context_Node,
Elem_Zz_00_Test_Form_000 type ref to If_Wd_Context_Element,
Stru_Zz_00_Test_Form_000 type Wd_This->Element_Zz_00_Test_Form_000 ,
Item_TEST1 like Stru_Zz_00_Test_Form_000-TEST1.
navigate from <CONTEXT> to <ZZ_00_TEST_FORM_000> via lead selection
Node_Zz_00_Test_Form_000 = wd_Context->get_Child_Node( Name = wd_This->wdctx_Zz_00_Test_Form_000 ).
get element via lead selection
Elem_Zz_00_Test_Form_000 = Node_Zz_00_Test_Form_000->get_Element( ).
get single attribute
Elem_Zz_00_Test_Form_000->set_Attribute(
exporting
Name = `TEST1`
Value = 'sss' ).
endmethod.

Hi Volker,
Thanks a lot for your help.:)
When I compile the WDA, the WDA don't occur any error. The WDA occurs error when I run the WDA.
1. In the st22 transcation code, I found the following code:
method RAISE .
  DATA: error TYPE STRING.
  error = MSG_STRING( msg = msg a = a b = b c = c i = i j = j k = k ).
************************begin of error************************************
  RAISE EXCEPTION TYPE CX_WD_GENERAL EXPORTING msg = error.
************************end of error*********************************
endmethod.
I think the method RAISE is invoked by CREATE_ADOBE method at the point:
      if sy-subrc ne 0.
--- there was an error; check, if it was an ADS related problem
        call function 'FP_GET_LAST_ADS_ERRSTR'

            e_adserrstr = lv_adserrstr.
      cx_wd_general=>raise( msg = lv_adserrstr ).

The following is the code of the CREATE_PDF method:

According the exception in the defaultTrace.0.trc:" Could not retrieve a password for credential: ReaderRights ", beacause Adobe reader8 don't get the credential in my machine, the error is occured when run the WDA. 
My question is how can I to get credential for Adobe Reader8 ?
Thanks a billion for your support and help.:-)
