List UIBB - Access to cell editor for a certain table line possible

Question

Hi,
I am looking for a way to access the cell editor of the last table line as I want to mark it as a special - summary - line.
I intend a similar approach like in WebDynrpo ABAP when accessing the node info and modifying the "CELL DESIGN" attribute like in the following code (copied from WD Comp WDR_TEST_TABLE, View CELL DESIGN, method FILL_CELL_DESIGNS) :
  data tab type IF_CELL_DESIGN=>Elements_Cell_Designs.
  data line type IF_CELL_DESIGN=>Element_Cell_Designs.
  data node_info type ref to if_wd_context_node_info.
  data attribute_info type wdr_context_attribute_info.
  data attr_value type WDR_CONTEXT_ATTR_VALUE.
  node_info = node->get_node_info( ).
  attribute_info = node_info->get_attribute( 'CELL_DESIGN' ).
  line-is_expanded = abap_true.
  line-is_leaf     = abap_false.
  line-key         = 'FIRST'.
  loop at attribute_info-value_set into attr_value.
    line-text = sy-tabix.
    concatenate 'Text #' line-text into line-text. "#EC NOTEXT
    line-cell_design = attr_value-value.
    insert line into table tab.
    line-is_leaf = abap_true.
    line-key = attr_value-value.
    line-parent_key = 'FIRST'.
  endloop.
  node->bind_table( tab ).
I suspect the method IF_FPM_GUIBB_LISTGET_DATA (or IF_FPM_GUIBB_LISTGET_DEFINITION) of my feeder class to be the right access point.
But unfortunately, I have not yet found out how to change the cell design for specific lines, only for whole columns.
Can anyone give me a hint here?
BTW: The "summary" line is not a sum of the lines above, but determined by backend logic, so not ALV-summary line for me.
Kind Regards

Hi,
A short update for all interested:
My current work around is to always set the lead selection to the summary line. It does in a kind "mark" that line as special as long as I cannot mark it using a different cell design.
How do I assure this?
I have implemented the following code in a redefinition of the method ADJUST_SELECTION:
*- alter selection
  DATA:
   ls_size TYPE rstabix.
  "get index of summary line
  ls_size-tabix = mo_collection->size( ).
  "change only if there are any cash conc. proposals
  IF ls_size-tabix > 0.
    "do FPM selection
    CLEAR: ev_lead_index, et_selection.
    ev_lead_index = ls_size-tabix.
    APPEND ls_size TO et_selection.
    "do BOL selection
    mo_collection->if_bol_bo_col_multi_sel~unmark_all( ).
    mo_collection->if_bol_bo_col_multi_sel~mark( iv_index = ls_size-tabix ).
  ENDIF.
The general downside is, that no other selection is possible!
The selection is always reset to the summary line with each roundtrip.
Waiting for a better solution...
Kind Regards,
Robert
