Hi,
I have a repository function that enable/disable an entity here is the code:
@Override
public int updateCrewMemberStatus(CrewMember crewMember, boolean status) {
Query query = entityManager
.createQuery("update CrewMember c set c.enabled=:status where c=:crewMember");
query.setParameter(query.getParameter("crewMember", CrewMember.class),
crewMember);
query.setParameter(query.getParameter("status", Boolean.class), status);
return query.executeUpdate();
}
and here is the test code:
@Test
public void testupdateCrewMemberStatus() {
Pilot pilot = createPilot();
crewMemberRepository.save(pilot);
crewMemberRepository.getEntityManager().flush();
assertEquals(1,
crewMemberRepository.updateCrewMemberStatus(pilot, false));
crewMemberRepository.getEntityManager().flush();
CrewMember crewMember = crewMemberRepository.findById(pilot.getId());
Boolean queryForObject = simpleJdbcTemplate.queryForObject(
"select enabled from CREWMEMBER where id=?", Boolean.class,
crewMember.getId());
LOGGER.debug(crewMember.toString() + " but queryObject: "
+ queryForObject);
}
When i run test it gives me a crewmember object with enabled field "true". But queryForObject variable is "false"(crewmember entity ,i think,also have to have enabled field false since it is already updated). Here is the debug output:

AND ((t1.ID = t0.ID) AND (t0.CREW_TYPE = ?)))

I could not understand the behaviour of the cache here. Why did't it update? Also if i put enetityManager.refresh in updateCrewMemberStatus before return then it is working. Any idea?
