Imports/subscriptions from Google Calendar with non-unique UID's missing in Team Calendars

XMLWordPrintable

      NOTE: This bug report is for Confluence Server. Using Confluence Cloud? See the corresponding bug report.

      Summary

      Event information is not imported whenever you try to import an ICS file from Google Calendars that contains repeat events. If you open the ICS file in a text editor and there are multiple events with the same UID parameter, only 1 event will get imported. All others will be missing and no logs are captured (even in DEBUG) stating this error.

END:VEVENT

      In this example, only the event for 09-06-2015 will get imported and all other events with this UID will not.

      Environment

      Confluence with Team Calendars version 5.2.18

      Steps to Reproduce

      1. Install Team Calendars
      2. Click on Add Calendar --> Import Calendar
      3. Upload an iCal file that includes repeat events with the same UID parameter.

      Expected Results

      All events get imported or a warning comes up stating why this cannot be completed.

      Actual Results

      Events are missing in Team Calendars.

      Workaround

      Editing the iCal file in a text editor and changing the UID parameter for those repeat events then saving will result in a successful import after trying again. Example above with unique UID (adding the word TWO before the UID)

      BEGIN:VEVENT
DTSTART:20150918T150000Z
DTEND:20150918T163000Z
