Handling checkboxes in ALV Grid.

Question

Hi  guys.
I have displayed an ALV grid with checkboxes. I want to opearate on the selected checkboxes by the user by clicking on a added button.
I am using oops and using function set_table_for_first_display.
if no box is selected the function works properly. If i select a checkbox, i get a dump.
Thanks
