I am trying to refactor the Spring Webflow BookingFaces application to use a Spring Data JPA repository. After including the repository scan in the configuration file, I receive a webflow serialization exception on the HotelLazyDataModel object which was refactored to hold a reference to a Spring Data JPA Repository. However, I receive the same error with the original implementation holding a reference to the JPA Service (Repository) as well once the repository scan is added to the config file. Would appreciate any assistance if anyone has run in to this problem. Thanks.
