.. include:: /Includes.rst.txt ========================== TYPO3 Exception 1260881688 ========================== .. include:: /If-you-encounter-this-exception.rst.txt The error occurs if there is a newly created Domain Object where the attribute uid is not set. This happens because newly created Domain Objects were not persisted directly after adding them to a repository. You have to get an instance of the PersistenceManager :: $persistenceManager = $this->objectManager->get('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\PersistenceManager') and persist it by hand with `$persistenceManager->persistAll()`.
