Load / Modify / Reload / Save

I just read through part 4 of one of tutorials I've been using to go through the MVC stuff.

Unfortunately, it suggests that to do an update, you need to reload the object, update it, then save it. So, if the values have changed since you populated the page, then you'll just overwrite them.
