Dropdown in tableview iterator doesn't show values

Question

Hi everybody;
I'm new to BSP. I'm creating a small BSP MVC application.
I have a table with a few columns; I needed to add an extra column in which a dropdown would be shown.
I created an iterator class and implemented the following in the GET_COLUMN_DEFINITIONS in order to add the extra column:
method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS .
FIELD-SYMBOLS: <def> LIKE LINE OF p_column_definitions.
*First normal columns
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'CAMPAIGN_CD'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'CAMPAIGN_NM'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'COMMUNICATION_CD'.
*<def>-EDIT = 'X'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'IDCLIENT'.
*<def>-EDIT = 'X'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'CONTACT_DTTM'.
*<def>-EDIT = 'X'.
*Finally; our defined column for status dropdown
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'STATUS'.
<def>-TITLE      = 'Status'.
endmethod.
Then I coded the following in the render_cell_start method to create the dropdown itself:
method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START .
  DATA: lt_table TYPE TIHTTPNVP,
        ls_table TYPE IHTTPNVP.
  CASE p_column_key.
    WHEN 'STATUS'.
      CLEAR: ls_table, lt_table.
      REFRESH lt_table.
      ls_table-name = 'OK'.
      ls_table-value = 'OK'.
      APPEND ls_table TO lt_table.
      ls_table-name = 'KO'.
      ls_table-value = 'KO'.
      APPEND ls_table TO lt_table.
      DATA lt_stat TYPE REF TO DATA.
      GET REFERENCE OF lt_table INTO lt_stat.
      p_replacement_bee = CL_HTMLB_DROPDOWNLISTBOX=>FACTORY(
                            id                = p_cell_id
                            table             = lt_stat
                            nameOfKeyColumn   = 'NAME'
                            nameOfValueColumn = 'VALUE'
  ENDCASE.
endmethod.
The strange thing is that the dropdown is shown but no values at all. Can someone help me out?
Thanks
Kind regards,

Hi,
Yes indeed. I did not know that the table and its reference had to be declared in the attributes of the iterator.
Another question; how to set the selected value of the dropdown after choosing a value which executes an action via the event DO_HANDLE_DATA?
The right value is passed through to DO_HANDLE_DATA, but how do I have to set the dropdown to the selected value? In which event etc?
Thanks
Kind regards
