Сообщение от SuperStar88

На некоторых формах в Init() прописаны такие штуки, для чего они?
(Например, форма InventTable)

    SysListPageHelper::handleInitPreSuper(element);

    super();

    SysListPageHelper::handleInitPostSuper(element);

Как насчет заглянуть внутрь и посмотреть как оно работает? Там и с документацией тоже все норм вроде.
