      Issue summary

      With Collaborative Editing On and Synchrony Hard Data Removal Enabled in the Scheduled Jobs, the editor sometimes will randomly repeat the content and causing the content to be duplicated after saving the page.

      Steps to replicate the issue

      Creating a two pages

      1. Create a page with title Page 1.
      2. Create a child page with title Page 2. This page must contain some text.
      3. Save Page 2

      Removing Synchrony Data (Hard)

      1. Go to http://<base url>/admin/scheduledjobs/viewscheduledjobs.action
      2. Find on the page Synchrony Data Removal (Hard)
      3. Click Run button to trigger the Hard Data Removal job.

      Reproduce the bug

      1. Return to the Page 1 created earlier
      2. (the next step need to be done very quickly)
      3. On the left side, in the Page Tree, click Page 2 link, and press E keyboard shortcut repeatedly at the same time until the page opens for editing. This steps to trigger the editor to load slowly.

      Expected behavior

      Exact content loaded in the Editor.

      Actual behavior

      Page load for editing, and after a while (few seconds/milliseconds) a duplicate content (text) appears.

      Notes

      Issue happen randomly for normal editing. Only when the editor took sometime (few seconds) to load. Users who experience slow network connection while loading the editor usually hit into the issue.

      Workaround

      Issue does not persist after turning Collaborative Editing mode to Off and disabling Synchrony Data Removal (Hard).

            Hi All,

            We've investigated this issue with the reporting engineer and have been unable replicate it or find cause for the behaviour.

            The issue was opened whilst the other duplicate content bugs discussed in Confluence Server and Data Center: Content duplication fix and next steps - Atlassian Community were unpatched, and we believe it is likely that one of these other bugs caused the behaviour.

            Supporting that conclusion is that we used the hard eviction function to replicate the issue we saw in CONFSERVER-69074: Duplicate Content Shown When Editing A Page After Modifying An Attachment (fixed in Confluence Server and Data Center 7.15.0, 7.4.15, 7.13.4), so it's wholly possible the hard eviction consideration is a step in the problem, rather than a primary driver.

            As development and support have been unable to replicate the issue, we're going to go ahead and close this out, however we'll revisit the issue if we encounter any reports with associated Collaborative Editing Feedback Tool files.

            b2503393acb9 - Can you please review the information at Confluence Server and Data Center: Content duplication fix and next steps - Atlassian Community. It lists a number of ways this issue can present after the fix is implemented.

            We'll continue to keep an eye out for these issues, so if you're able to capture duplication at the time it occurs, please capture a report for us to investigate.

            Thanks,
