Dynamic Table Width for XML Renderer

Question

Hi Guys,
I'm looking for a way to get a XML documents with a dynamic table width.
Using a dynamic result table doesn't work.
The test program looks like this.
REPORT  xml_test.
TYPE-POOLS: ixml.
DATA: go_ixml TYPE REF TO if_ixml.
go_ixml = cl_ixml=>create( ).
DATA:  go_xml_document TYPE REF TO if_ixml_document.
go_xml_document = go_ixml->create_document( ).
DATA: go_xml_root_elm TYPE REF TO if_ixml_element.
go_xml_root_elm  = go_xml_document->create_simple_element(
           name = 'flights'
         parent = go_xml_document
         value  = 'Texas Flight' ).
DATA: go_xml_main_elm TYPE REF TO if_ixml_element.
go_xml_main_elm  = go_xml_document->create_simple_element(
              name = 'airline'
            parent = go_xml_root_elm  ).
DATA: lv_rc TYPE i.
lv_rc = go_xml_main_elm->set_attribute( name = 'code' value = 'LH401' ).
DATA: go_xml_streamfactory TYPE REF TO if_ixml_stream_factory.
go_xml_streamfactory = go_ixml->create_stream_factory( ).
* Static Creation of X tab ---------------------------------------------
DATA: BEGIN OF gs_xml_line,
         data(255) TYPE x,
       END OF gs_xml_line.
DATA:  gt_xml_table       LIKE TABLE OF gs_xml_line,
       gv_xml_size        TYPE i,
       go_ostream         TYPE REF TO if_ixml_ostream.
* END Static Creation of X tab ------------------------------------------
* Dynamic Creation of X tab ---------------------------------------------
FIELD-SYMBOLS: <lf_x_tab>  TYPE STANDARD TABLE,
               <lf_x_stru> TYPE ANY.
DATA: lt_fldcat TYPE lvc_t_fcat.
DATA: lr_tab TYPE REF TO data,
      lr_stru  TYPE REF TO data,
      ls_fldcat TYPE lvc_s_fcat,
      lv_dyn_width TYPE i.
lv_dyn_width = 255.
* Append Dynamic Field.
CLEAR ls_fldcat.
ls_fldcat-fieldname = 'DATA' .
ls_fldcat-datatype  = 'X'.
ls_fldcat-inttype   = 'X'.
ls_fldcat-intlen    = lv_dyn_width.
APPEND ls_fldcat TO lt_fldcat .
* Create dynamic internal table and assign to FS
CALL METHOD cl_alv_table_create=>create_dynamic_table
  EXPORTING
    it_fieldcatalog = lt_fldcat
  IMPORTING
    ep_table        = lr_tab.
ASSIGN lr_tab->* TO <lf_x_tab>.
* Create dynamic work area and assign to FS
CREATE DATA lr_stru LIKE LINE OF <lf_x_tab>.
ASSIGN lr_stru->* TO <lf_x_stru>.
CHECK sy-subrc  = 0.
* END Dynamic Creation of X tab ------------------------------------------
* Static Table works
go_ostream = go_xml_streamfactory->create_ostream_itable( table = gt_xml_table ).
* Dynamic Table doesn't work
go_ostream = go_xml_streamfactory->create_ostream_itable( table = <lf_x_tab> ).
* Show result
DATA: go_renderer        TYPE REF TO if_ixml_renderer.
go_renderer = go_ixml->create_renderer( ostream  = go_ostream
                                        document = go_xml_document ).
lv_rc = go_renderer->render( ).
gv_xml_size = go_ostream->get_num_written_raw( ).
DATA: lv_str  TYPE string,
      lv_xstr TYPE xstring.
LOOP AT gt_xml_table INTO gs_xml_line.
  lv_xstr = gs_xml_line-data.
  CALL FUNCTION 'HR_KR_XSTRING_TO_STRING'
    EXPORTING
*                          FROM_CODEPAGE       = '8500'
      in_xstring          = lv_xstr
*                          OUT_LEN             =
   IMPORTING
     out_string          = lv_str.
  WRITE: / lv_str.
ENDLOOP.
If the static table is used, the program gets a result, but it doesn't work with the dynamic table.
* Static Table works
go_ostream = go_xml_streamfactory->create_ostream_itable( table = gt_xml_table ).
* Dynamic Table doesn't work
go_ostream = go_xml_streamfactory->create_ostream_itable( table = <lf_x_tab> ).
Any Ideas?
Thanks in advance

I've never used dynamically changing popup items variable before, and I'm not sure it will work(?)
But, if it's displaying a long string, it does not sound like 'items' is being assigned a proper table yet.
I don't know what you mean by a  "chunk" of values. I assume you mean table.
In any case, if SYPNEventResults[1].title is a string, then SYPNEventResults[1].value can be any legal lua type.
Likewise for SYPNEventResults[2], SYPNEventResults[3], ...
If you can index/display the title with this syntax, e.g. LrDialogs.message( SYPNEventResults[1].title ), then the popup should be initialized thusly:
viewFactory:popup_menu {
       items = SYPNEventResults,
       value = LrView.bind('eventname2'),
       width_in_chars = 40,
if a function is returning multiple values, then to get it into a table "array", do this:
local tableArray = { myTableArrayFunc( myTableArrayParameters ) }
Does this help?
