Hi, We are using OBD with Spring and transactions are managed by Spring. Our spring service interfaces take list of objects and persist them and the interface service is marked as @ Transactional ... object we don't get it back on lookup. This is with transactions we are not able to retrieve

at transaction commit. ObjectDB checks any database object that is being updated or deleted. An exception is thrown if the check finds that another transaction has already updated the object after the current transaction retrieved it, so the current transaction is attempting to modify a stale version
