marked @version. if annotation removed, goes fine - persist operation succeeds in entirely.
what role played @notnull constraint in case?
the unidirectional relationship not relevant. exact same thing happens though relationship changed bidirectional one-to-many department employee.
it looks version isn't set until entity modified, therefore rowversion null when entity first created. fails "not null" check. try instead , see if works:
@version @basic(optional = false) @notnull @column(name = "row_version", nullable = false) private long rowversion = 0l; what jpa implementation using?
