ALV selected rows are lost

Hi,

I am modifying contents of Node bounded with ALV in modify view to make cell editable/display. But after binding table with node selected rows on ALV table get lost. I tried to capture the selected rows in Modify view before updating node

using Get_selected_elements method

lt_selected_elements = lr_node1->get_selected_elements( ).

and at the end of Modify method used SET_SELECTED method to select back the selected rows but it didn't work.

Initialization and Lead selection are unchecked for this node.

please advise.

Thanks,

Alok
