К какому типу модулей относится модуль Мегафон? Модуль для работы с конвергентными тарифами для абонентов
Документации по этому модулю не нашёл ни в одной из версий документации, и в настройке его есть вопроси и ошибки в его работе и настройке
например при удалении созданного пакета вылетает ошибка
java.lang.Exception: java.lang.NullPointerException: Cannot invoke "ru.bitel.common.model.Page.setRecordCount(int)" because "page" is null

или при создании опции для любого конвергентного тарифа при нажатии кнопки Применить ничего не происходит, опция не создаётся и ошибка не вылетает, не совсем понятно где можно запросить итоговый реестр платежей, есть вообще где-то хоть какая то документация по нему, как правильно создавать в нём пакеты, номера MVNP
есть ли у разработчиков возможность добавить задел по этому модулю на форуме?

Не знаю просто в каком и разделов создавать вопросы по модулю "Мегафон"
