BSP Tableview error when trying to bind an itab within an itab

Question

Hello dear forum members,
I got a requirement to dynamically generate tableviews and bind them to a model's attribute (an itab 'model->gt_prd_grps' which holds the actual internal table to display as tableview 'model->gt_prd_grps-prods_table' within it). Below code would give you a correct picture.
BSP View code:
LOOP AT model->gt_prd_grps INTO ls_prd_grps.
        lv_idx = sy-tabix.
        CONCATENATE 'ProductsList_' ls_prd_grps-prod_group INTO lv_tableid.
        CONCATENATE '//model/' 'gt_prd_grps[' lv_idx '].prods_table' INTO lv_bind_str.
        CREATE OBJECT lr_tableview.
        lr_tableview->id            = lv_tableid.
        lr_tableview->headertext    = ls_prd_grps-prod_grp_desc.
        lr_tableview->_table        = lv_bind_str.
        lr_tableview->headerVisible = 'true'.
        lr_tableview->footerVisible = 'true'.
        lr_tableview->filter        = 'SERVER'.
        lr_tableview->design        = 'alternating'.
        lr_tableview->sort            = 'SERVER'.
        lr_tableview->fillUpEmptyRows = 'false'.
        lr_tableview->selectionMode   = 'NONE'.
        lr_tableview->iterator        = lo_prdctschtb_iter.
        lr_tableview->emptyTableText  = 'No Products available.'.
        tableview_str = lr_tableview->if_bsp_bee~render_to_string( page_context ).   %>
  <%    lv_col_count_default = 1. lv_row_count_default = lv_row_count_default + 1.   %>
  <htmlb:gridLayoutCell columnIndex = "<%= lv_col_count_default %>"
                        rowIndex    = "<%= lv_row_count_default %>"
                        colSpan     = "3" >
                        <%= tableview_str %>
</htmlb:gridLayoutCell>
<% ENDLOOP. %>
I am encountering dump while trying to run the above BSP view and the error says "BSP exception: No structure component with the name "PRODS_TABLE[1].PRODUCT_ID" exists"
Actually the user would select from the tableview via a 'select' column which would be rendered as checkbox and the MVC binding would greatly reduce the effort of manually transferring the user selections to the respective model table(s).
Please suggest if the above way is possible and if so how to overcome the exception i am facing OR do i have to manually capture the tableview selection via CL_HTMLB_MANAGER=>GET_DATA.
Huge thanks in advance,
Ram

Hi Raja,
I am getting the dump as soon as the view is called. The tableview to be displayed is indeed the nested table only and the user can select the records via the 'checkbok' column in the tableview.
Also, when i debugged, the dump occurs exactly at the below point:
tableview_str = lr_tableview->if_bsp_bee~render_to_string( page_context ).
Regards,
Ram
