There can't be a primary key ID of 0 as 0 = false. As such you're not passing an id to saveField so it's running an INSERT instead of an UPDATE.
You need to take a look at your db table definition as it should not allow a primary key of 0 if it's an INT/Primary Key/Auto Increment which it should be.
