- on picture.php, related categories under the element are displayed in
global_rank order - when adding a new virtual category, initializes its global_rank - bug fixed : in admin/cat_list, false next rank - in admin/cat_modify, complete directory is calculated only if category is not virtual - admin/picture_modify rewritten : graphically nearer to admin/cat_modify, virtual associations are back - update_category partially rewritten : take an array of categories in parameter, becomes optionnaly recursive, use the set_random_representant function, set a random representant for categories with elements and no representant - bug fixed : on a search results screen, elements belonging to more than 1 category were shown more than once - bug fixed : in admin/cat_modify, changing a value in a textefield and hitting enter was setting a new random representant git-svn-id: http://piwigo.org/svn/trunk@635 68402e56-0260-453c-a942-63ccdbb3a9ee
