Формулировка задачи:

У меня возникла проблема, в списке пользователей. Список не обновляется если в него зайти повторно, после того как удалил одного пользователя.помогите исправить. Что бы зайти в проге в мою проблему, нажмите 1, удалите одного из юзеров по паролю и зайдите туда ещё раз и увидите что он вернулся(юзер). Лист с пользователями находиться в методе delet.
