У меня есть два списка, оба используют один и тот же класс (Часть). Первый список - это «главный» список (engineerParts), второй (partDefaults) - список значений атрибутов для этих частей.
Первый список содержит 263 элемента, второй - 238. Итак, последний список должен содержать 263. Однако его нет, он содержит 598 !!
