127 | Merge on detached entitiesHello, it is possible to merge detached entities? There are some attached entities which load from the database. The transaction is finished and the entities become detached. In a new transaction the fields of the detached entities will be changed and a merge by em.merge(entity) will be saved |

26 | Navigation through lazy loading from Detached ObjectsA main limitation of detached objects (as explained on the Detached Entities manual page) is: Retrieval by navigation from detached objects is not supported, so only persistent fields that have been loaded before detachment should be used.
