Javascript 使用parse4cn1库在Codenameone上保存ParseUser或ParseObject时出错

我正在尝试保存parse4cn1 3.0 ParseUser或ParseObject。对象保存在模拟器上，但是在Java脚本端口上我收到一个错误。注意：ParseFile save（）可以在模拟器和Java脚本端口上工作

public void createTask(String userObjectId, String taskName, String taskDescription, String url) {
    try {
        ParseObject task = ParseObject.create("Task");
        task.put("userId", userObjectId);
        task.put("taskName", taskName);
        task.put("taskDescription", taskDescription);
        task.put("url", url);
        task.save();
    } catch (ParseException e) {
        e.printStackTrace();
    }
}

JavaScript端口中似乎缺少

getCanonicalName（）

。我不确定这是否是我们应该在JavaScript端口中修复或添加为parse4cn1的请求。这似乎不是解析所必需的

---

由于该方法一开始就不推荐使用，因此我确信它可以删除。

分叉和更新parse4cn1库最终成为更快的临时解决方案。我删除了所有出现的

getCanonicalName（）

，重建了cn1lib并重新提交了Java脚本端口构建

生成成功，save（）方法现在可以工作了。谢谢

需要使用此修复程序更新parsecn1 cn1lib
