Occasionally you’ll run into a use case where multiple users might edit the same object/data at the same time. If two people are editing the same information, generally the last one to submit the web form wins (last writer). ORM frameworks, like Hibernate, provide the ability to detect when the object’s version changed. If you’re using something like Wicket, with it’s detachable model support, integrating version support is very easy.
