I am trying to persist an empty HashSet in App Engine. It persists fine but when I pull the the item that contains the HashSet from the data-store the HashSet is now null. What can I do to force App Engine to store an empty HashSet? Or, do I just need to check for null and create the HashSet each time until it has something in it? I'm guessing I would create a field hashSetEmpty and not create the HashSet till I ran code that added to the HashSet.
