Problem: Value in Inputfield empty

Question

Hello,
I use the htmlb:tableView and defined one column as editable where a dropdown-list is assigned (by iterator).
In the "OnInputProcessing" I read the new selected value of the edit-column and write this value to my internal table.
Here the Coding of this:
Get Data for tv_cols, the current edited row, and update table
DATA: tab_view TYPE REF TO CL_HTMLB_TABLEVIEW.
DATA: tab_data TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.
DATA value TYPE STRING.
DATA: inputfield TYPE REF TO CL_HTMLB_INPUTFIELD.
FIELD-SYMBOLS: <row> TYPE ZSEM_0APPR_REQU_1.
tab_view ?= CL_HTMLB_MANAGER=>GET_DATA(
                        request      = runtime->server->request
                        name         = 'tableView'
                        id           = 'tab_APPR_REQU_status' ).
get changes into internal table
get changes into internal table
IF NOT tab_view IS INITIAL.
  tab_data = tab_view->data.
  IF NOT last_selected_rowIndex IS INITIAL.
    READ TABLE gtab_APPR_REQU_1
       INDEX last_selected_rowIndex
       ASSIGNING <row>.
    value = tab_data->GET_CELL_ID(
                  row_index    = last_selected_rowIndex
                  column_index = '3' ).
    inputfield ?= CL_HTMLB_MANAGER=>GET_DATA(
                        request      = request
                        name         = 'inputField'
                        id           = value ).
    IF inputField->value is not initial.
        <row>-STATUSIQMS = inputField->value.
    ENDIF.
  ENDIF.
  last_selected_rowIndex = tab_data->SelectedRowIndex.
ENDIF.
Now my problem:
If I select a new line in the tableView the value of the line selected before is in the variable "inputField->value" and everything is working fine.
But if I had selected a line and changed the editable column and then push an save-button on the BSP-Site the variable "inputField->value" is empty. Though the "inputfield" itself was assigned correct.
What's going wrong here? How can I get the new value of last changed line?
Thanks in advance

Whenever you select a new line the OnInputProcessing fires and you can read the value and store it then when the screen is rendered again the value is there and they are now on the new line to edit.
When you build the element into your table it is assigned the [tablename]_[cell]_[row] and if you know those items then you can do a simple get_form_field call.
Then you have the value and you can do a table UPDATE to save the value.
