Следующая проблема:
Я пытаюсь визуализировать HTML вручную в контроллере.Нашел что-то подобное здесь и попробовал это.При рендеринге статического контента это не проблема, но когда я пытаюсь получить доступ к модели, я получаю исключения из пружинного связывания (freemarker).
Проект - это проект с простой загрузкой, со следующими простыми компонентами:
