Fail to update user's professional data and personal data

I am using Talend ESB to create users in Bonita BPM 7.0 via REST APIs, and it can be successfully done to create new users or update other properties such as manager id. However, it fails to update emails if I set REST request like below

{
"id":"400",
"userName":"100005",
"firstname":"Changjie",
"lastname":"Xu",
"job_title":"Developer",
"manager_id":"395",
"personnal_data_email":"changjie.xu@synale.com",
"professional_data_email":"changjie.xu@synale.com"
}

There's no error be logged in Bonita log file ("bonita.2016-01-06.log")

I tried the same in SOAPUI too, and find Bonita returns "HTTP/1.1 200 OK" while emails are not updated.

Anyone could help me on this?
