Description

If an assignment is linked to the calendar, if a user goes to that calendar item and selects the assignment link, a NPE stack trace is displayed. I'll attach a stack trace to the JIRA.

Sample link from calendar:

javascript:change_parent_url('https://HOSTNAME/portal/directtool/098e22d8-71ac-402c-b493-5838a8d1df3d?assignmentId=2ac536da-5f5b-4764-9f25-1c703181ac5a&assignmentReference=/assignment/a/b538992a-1772-4630-8fd3-c8d8809b89b4/2ac536da-5f5b-4764-9f25-1c703181ac5a&panel=Main&sakai_action=doView_assignment');
