Summary


Viewing a page shows the following error in logs.

2020-05-04 23:07:05,044 ERROR [http-nio-8080-exec-13] [atlassian.confluence.servlet.ConfluenceServletDispatcher] sendError Could not execute action
 -- url: /pages/viewpage.action | traceId: 1273a70858101de8 | userName: admin | referer: http://localhost:8090/login.action?os_destination=%2Fpages%2Fviewpage.action%3BRelease%2BNote%2BCreation%2BStandards%2Band%2BGuidelines&permissionViolation=true
java.lang.RuntimeException: Error rendering template for decorator root
	at com.atlassian.confluence.setup.velocity.ApplyDecoratorDirective.render(ApplyDecoratorDirective.java:162)
	.
	Caused by: org.hibernate.HibernateException: Unable to resolve owner of loading collection [[com.atlassian.confluence.core.ContentEntityObject.contentProperties#152548091]] for second level caching
	at org.hibernate.engine.loading.internal.CollectionLoadContext.addCollectionToCache(CollectionLoadContext.java:321)

In some cases the error can happen on some other actions in Confluence as well. Though, as long as the cause of the error is the same we can proceed with the resolution here.

Cause


The actual error is unable to load an element of ID 152548091 from the cache. This ID is seen in the logs.

Solution

Try clearing the cache of Confluence to force a refresh.

  • General Configuration > Cache Management
  • Select Flush all at the bottom of the page

Other Notes

If the issue isn't resolved by flushing cache:

  • Query the database for the relevant ID

    Tested in Postgres
    SELECT * 
    FROM contentproperties
    WHERE propertyid=<element id from caused by exception>;
  •  Rebuild the indexes of the system using steps provided in Content Index Administration
