get_cell_value doesn't work

[#1]

Dear,

I tried to get the cell value when user clicks on a row in a table view by get_cell_value method but it always returns null. Does any one can help me?

My code is:

BSP Page:

<htmlb:tableView id = "tv1"
                        headerText = "List of Employees"
                        headerVisible = "true"
                        footerVisible = "true"
                        design = "alternating"
                        visibleRowCount = "20"
                        table = "<%= employee %>"
                        onRowSelection = "rowSelection"
                        selectionMode = "SINGLESELECT">
        <htmlb:tableViewColumns>
          <htmlb:tableViewColumn columnName = "empid" title = "ID">
          </htmlb:tableViewColumn>
          <htmlb:tableViewColumn columnName = "firstname" title = "First Name">
          </htmlb:tableViewColumn>
          <htmlb:tableViewColumn columnName = "lastname" title = "Last Name">
          </htmlb:tableViewColumn>
        </htmlb:tableViewColumns>
       </htmlb:tableView>

OnInputProcessing:

CLASS cl_htmlb_manager DEFINITION LOAD.

IF event_id = cl_htmlb_manager=>event_id.
  DATA:
        event TYPE REF TO cl_htmlb_event.

  event = cl_htmlb_manager=>get_event( runtime->server->request ).

  IF event->name = 'tableView'.
    IF event->event_type = 'rowSelection'.
      DATA:
        selrow TYPE REF TO cl_htmlb_tableview.

        selrow ?= cl_htmlb_manager=>get_data( request = request
                                            name    = 'tableView'
                                            id      = 'tv1' ).

      DATA:
            tv_data TYPE REF TO cl_htmlb_event_tableview,
            selected_row_index TYPE i,
            empid TYPE string.

      tv_data = selrow->data.
      selected_row_index = tv_data->selectedrowindex.

      CALL METHOD tv_data->get_cell_value
        EXPORTING
          row_index    = selected_row_index
          column_index = '1'
        receiving
          value        = empid
          .

      navigation->set_parameter( name = 'empid' value = empid ).
      navigation->next_page( 'TOCONTACT' ).
    ENDIF.
  ENDIF.

ENDIF.

if you look at the source of the get_cell_data method, you will see that it uses get_form_field method which requires the field to be read should be html input element. however when a non editable tableview is rendered, it doesnt render input elements, so this method wont work for non editable tables.

to read a particular cell value from the table view use the approach explained in the following thread
