我正在尝试使用Parse查询获取Object.

这是我的代码:

ParseQuery<ParseObject> query = ParseQuery.getQuery("Conference");
    query.findInBackground(new FindCallback<ParseObject>() {
        public void done(List<ParseObject> results, ParseException e) {
            if (e == null) {
                // Results were successfully found from the local datastore.
            } else {
                showLog(e.toString());
            }
        }
    });

我收到此错误:

com.parse.ParseException:java.lang.IllegalStateException:ParseObject没有'objectId'的数据.调用fetchIfNeeded()来获取数据.

BTW我的Conference班级包含指针.
