Enrolment

Hello,
I have been trying to use the IMS Enterprise enrollment with Moodle 1.8 and have found an odd problem. The parser picks up my xml file and creates the course and add the people just fine, but despite claiming to create the group (Section in the course) it does not. I have attached a copy of a very simple xml import that I have been testing with. I have tried manually creating the group in the course and then running the import to just add the people to the course and the group and it still fails to add them to the group.

The odd bit is that when I test this file on 1.7 and 1.9 it works correctly, the group is created and the people are added to the group within the course.

Has anyone else run into this problem? Or successfully used the IMS import to create and populate groups with a course with version 1.8?

Thanks,
Andy
