Redmine

this is the XML body I'm sending from my program to Redmine (last trunk version):

<issue><project_id>ace</project_id><parent id="46"/><subject>child 1</subject></issue>

POST http://172.17.10.53:3000/issues.xml HTTP/1.1

response from server:

  </relations>
</issue>

my output:

created child: issue: id=51 assignee: subject:child 1

I have the issue with id "46" in the same "ace" project so I expect the new issue to be created with the parent link, but it's created with no parent.

here's Redmine log:
