I tried the patch, but if one is trying to change the weight of children nodes at page /node/xxx/children, it will give the following error:
PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'customized' at row 1: UPDATE {menu_links} SET menu_name=:db_update_placeholder_0, plid=:db_update_placeholder_1, link_path=:db_update_placeholder_2, router_path=:db_update_placeholder_3, hidden=:db_update_placeholder_4, external=:db_update_placeholder_5, has_children=:db_update_placeholder_6, expanded=:db_update_placeholder_7, weight=:db_update_placeholder_8, depth=:db_update_placeholder_9, p1=:db_update_placeholder_10, p2=:db_update_placeholder_11, p3=:db_update_placeholder_12, p4=:db_update_placeholder_13, p5=:db_update_placeholder_14, p6=:db_update_placeholder_15, p7=:db_update_placeholder_16, p8=:db_update_placeholder_17, p9=:db_update_placeholder_18, module=:db_update_placeholder_19, link_title=:db_update_placeholder_20, options=:db_update_placeholder_21, customized=:db_update_placeholder_22 WHERE (mlid = :db_condition_placeholder_0) ; Array ( [:db_update_placeholder_0] => navigation [:db_update_placeholder_1] => 1480 [:db_update_placeholder_2] => node/6 [:db_update_placeholder_3] => node/% [:db_update_placeholder_4] => 0 [:db_update_placeholder_5] => 0 [:db_update_placeholder_6] => 0 [:db_update_placeholder_7] => 0 [:db_update_placeholder_8] => -49 [:db_update_placeholder_9] => 3 [:db_update_placeholder_10] => 1479 [:db_update_placeholder_11] => 1480 [:db_update_placeholder_12] => 1483 [:db_update_placeholder_13] => 0 [:db_update_placeholder_14] => 0 [:db_update_placeholder_15] => 0 [:db_update_placeholder_16] => 0 [:db_update_placeholder_17] => 0 [:db_update_placeholder_18] => 0 [:db_update_placeholder_19] => nodehierarchy [:db_update_placeholder_20] => TESTI Golf [:db_update_placeholder_21] => a:1:{s:10:"attributes";a:1:{s:5:"title";s:0:"";}} [:db_update_placeholder_22] => [:db_condition_placeholder_0] => 1483 ) in menu_link_save() (line 3140 of /xxx/public_html/includes/menu.inc).
