Bug 641045

Currently, @IndexColumn(name = "list_index") is commented out of PropertyList.  A quick look in the database will confirm that list_index is null for all properties.  Hibernate docs say that collections w/o @OrderBy/@IndexColumn are going to be considered bags, which explaining why ordering is lost between views.  We need to do the necessary testing to at list_index back, so that lists are properly stored and retrieved.  Might want to add a hook to the configuration manager bean to give property lists a default ordering if none is found after retrieving from the DB.  Likewise, it might be necessary to add checks upon persist to ensure list_index values make sense for a given property list.
