It's not possible to complete the scheduling for any reports. On view "Report Delivery Options", nothing happens when clicking on "Proceed". It's not possible to move to the next view that let write the cron expression.
The issue is related on a typo in WEB-INF/flows/report/database/batchReport/deliveryOptions.jsp "_evedntId_proceed" instead of "_eventId_proceed". The issue has been injected in a commit (bd4d3447b188560a188c7eb99009e8441ee13412) of Sep 22, 2015.
