Как вы можете видеть ниже, у меня есть приложение Da sh, которое генерирует маршруты по функциям, однако мои обратные вызовы для выполнения табличных вычислений не работают как expectet.
Я пытался разрешить обратный вызов этого приложения раньше и после обратных вызовов, которые обновляют таблицы, однако это не работает также.
Как причина, по которой эти обратные вызовы перестают работать, также есть в любом случае, чтобы сделать эту работу снова?
У меня есть функция диспетчера, что параметры запроса, также у меня есть функция, которая создает приложение, и функции, которые генерируют маршруты (страницы) в моем приложении.
