I also have a similar problem.
in my exsample:
@Entity
class Test {
@Id
@Column(name = "ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(nullable = false)
private Boolean isLatest;
}
# service
Test test = TestDao.getByCode("code")
test.setIsLatest(false)
TestDao.save(createTest())
#warning-log
Request completed without committing or rolling back transaction with
id 7. Transaction will be rolled back.
When I comment out the line of "TestDao.save(createTest())", test is
merged.
And when i comment out the lines to merge, "TestDao.save" is success.
I wanna merge and save for same Model.
why can't i do it?plz tell me about it.
