Flash flex中的数据存储

我的程序有问题。。。请告诉我什么是对的

这是我的程序的错误代码

mx.data::Conflict {
  cause = mx.data.messages::DataMessage {
    body = [["lessonid"],
    {
      lessonid = 17
      lessonplanid = 1

报告说，冲突类型的错误为

检测到冲突时调度 在该服务器上的两个挂起的更改之间 客户和提交的更改 另一个客户机，或在发生更改时 此客户端提交的结果检测 远程服务器上的冲突错误 目的地

您必须自己找出解决方案（这不是由Flex引起的，而是由您想要提交的数据引起的）

本地项已更改属性 这与遥远的变化相冲突

在我看来，你的验证失败了，因为

clientObject = valueObjects::Lessonplan {
    lessonid = 18
    lessonplanid = 1
    status = "active"
    studentid = 4   }

及

两者不相容。我想不允许更改lessionid

将代码格式化为代码是正确的（使用{}按钮或缩进4个空格）：这将有助于回答您的问题。这次我是为你做的，我怎么能允许呢？当我重新启动应用程序时，我可以看到更新已正确完成…但当我再次更新它时，它返回相同的错误..顺便说一句，我正在使用PHP服务，这可能是因为您需要合并（）或刷新（）您的本地数据，然后再提交。我阅读了您编辑的答案，但我仍然无法理解上面部分的意思。我在那个服务中禁用了数据管理..先生..非常感谢..你真是英巴..哈哈哈..你救了我未来的事业！！！！tnx再次追问：在我的理解中，“IMBA”是一种侮辱——我是做了什么冒犯你的事，还是我真的回答了你的问题？

originalObject = {
    lessonid = 17
    lessonplanid = 1
    status = "active"
    studentid = 4
  }
