Платформа 3V/Формы/Действия/Расчет элемента

Параметр, который вычисляет и устанавливает значение для указанного элемента управления, имеет следующую структуру:

1 {
2       "id": 111,
3       "controlId": 111,
4       "expressionId": 111,
5       "discriminator": "CalculateControlValueAction"
6 }

Описание свойств параметра

Свойство	Описание
id	Идентификатор параметра
controlId	Идентификатор элемента управления
expressionId	Идентификатор выражения
discriminator	CalculateControlValueAction

Пример использования(вычисление периода)

Кейс: Вычислить длительность периода по датам начала и конца периода.

В отдельном выражении из конечной даты вычесть начальную и вывести ее в контрол.
