Hi, Jehan:
Did you get similar NullPointerException stacktrace with 2.7.1 code?
The User object shouldn't be null for that line, otherwise, the code would
fail with NPE earlier.
Can you execute the following queries?
1. to find out all the user ids and eids for Student role user in site:
select t1.user_id, t5.eid from SAKAI_REALM_RL_GR t1, Sakai_realm t2,
sakai_realm_role t3, sakai_realm t4, sakai_user_id_map t5 where
t1.realm_key=t2.realm_key and t1.role_key = t3.role_key and
t3.role_name='Student' and t1.realm_key=t4.realm_key and
t4.realm_id="/site/05fb8996-d8c2-4a6b-92ac-0db7b161a94b" and
t1.user_id=t5.user_id;
Please replace the site id with yours instead.
2. find out how many assignment submission has been made for particular
assignment:
select submitter_id from assignment_submission where context =
"assigment_id";
Please replace the assignment id with the actual assignment id of interest.
Thanks,
- Zhen
