The latter situation is guaranteed to cause the problem below.
If that is not the cause, then show me your implementation of EditStudentInfoAction.execute.

Who can tell me how to deal with this?
If I retry to invoke the method for some times, the method could execute successfully.
So??????????????????????????????
