This is where we'll load the list of entities. Not because it is any better than the execute() method, I would actually prefer doing it in the execute method. But since these list actions can be the target of redirects after errors, actionErrors may not be empty which would mean execute() would never get called. One way around this would be to have a different interceptor stack just for these list actions that doesn't do validation, but for now we'll just use the prepare() method. We can change it easily enough later if this becomes an issue for some reason.
