Артем Басов ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYjdmYmUxN2Q4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15480?atlOrigin=eyJpIjoiYjdmYm... ) HHH-15480 ( https://hibernate.atlassian.net/browse/HHH-15480?atlOrigin=eyJpIjoiYjdmYm... ) Merging of ModWorkUnit with CollectionChangeWorkUnit followed by another ModWorkUnit leads to lost modified flags ( https://hibernate.atlassian.net/browse/HHH-15480?atlOrigin=eyJpIjoiYjdmYm... ) Issue Type: Bug Affects Versions: 5.4.32 Assignee: Chris Cranford ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Components: hibernate-envers Created: 03/Sep/2022 07:51 AM Priority: Major Reporter: Артем Басов ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) This is, in a sense, a combination of HHH-7918 ( https://hibernate.atlassian.net/browse/HHH-7918 ) Closed and HHH-7948 ( https://hibernate.atlassian.net/browse/HHH-7948 ) Closed. Steps: * Tx1: Create ListRefEdEntity * Tx2: * Fetch ListRefEdEntity created at (1) * Create and persist ListRefIngEntity associated with ListRefEdEntity fetched at (a) * Change its data , associate with ListRefIngEntity * Flush * Change its data again This will lead to revision of ListRefEdEntity created after Tx2 with reffering_mod=false See a PR for a test case The way I see the problem is that by discarding both CollectionChangeWorkUnit and ModWorkUnit#data we are relying on the difference between oldState and newState , but debug shows that both states already contain added ListRefIngEntity.
