code: function getDataForUserId(formName) {
    var userId = pad.getUserId();
    var message = {};
    message.type = 'USERINFO_GET';
    message.padId = pad.getPadId();
    message.userInfo = {};

docs: Thanks to the userId, we can get back from the Db the options set for this user
  and fill the fields with them
