Здравствуйте, Owen Logic (версии 2.5.344.0) вылетает с ошибкой "Object reference not set to an instance of an object" в симуляции когда дело доходит до смены экрана на экран с ProgressBar в котором установлена переменная отображения. Если указать "Не указана" то вылета нет. Переменная определяется со старта программы, так что вылет не должен быть связан с косяком в программе ST. Не знаю что думать. Заранее спасибо.
Вот stacktrace ошибки:
