Maybe original_export_menu is None. You have to verify this before call
.elements('a')
if w2p_grid_tbl:
original_export_menu = grid.element('div.w2p_export_menu')
if original_export_menu :
export_menu_links = original_export_menu.elements('a')
But, if original_export_menu is None, this is because you don't find
'div.w2p_export_menu' inside the grid elements, and this is because you
don't use web2py.css in your styles.
