      I've provided both XAR:

      • WORKING_application-meeting-ui.xar
      • BROKEN_application-meeting-ui.xar

      Steps:

      • I've installed Meeting app
      • I've built it locally - resulting in WORKING_application-meeting-ui.xar
      • Imported the changes
      • I've applied the PR https://github.com/xwiki-contrib/application-meeting/pull/23
      • Rebuild the PR - resulting in BROKEN_application-meeting-ui.xar
      • Failed to import the PR changes: error + nothing changed for the pages
