Fixed: Add/Modify Calender Event Screen is Broken. The issue was due to screen expect the list and script is fetching single value. Change from queryFirst to queryList in the script. (OFBIZ-10173) Thanks Ratnesh Upadhyay for reporting the issue. Thanks Yogesh Noaroliya for providing fix for the issue.
