I am not an expert on WW, though the normal way to deal with 'missing' http data is to set a default value for the property and it can be overridden by the request parameter...
i.e. if you set protected boolean newsletter = false; instead of true, then WW will call the setNewsletter(true) when the checkbox is checked.
