Mock not being injected for one of the testcases

I have a jsf spring application and using mockito for my unit test.I keep getting null pointer exception when i run my unit test iEmployeeService. There is no null pointer for iSecurityLoginService.

Method to be mocked

@Autowired
IEmployeeService iEmployeeService;
@Autowired
ISecurityLoginService iSecurityLoginService;
public void addEvent() {

    entityEventsCreate.setTitle(entityEventsCreate.getTitle());

    entityEventsCreate.setModifiedBy(iSecurityLoginService
                .findLoggedInUserId());

            int eventId = iEmployeeService
                    .addEmployeeTimeOff(entityEventsCreate);
}

Unit test is

@Mock
ISecurityLoginService iSecurityLoginService;

@Mock
IEmployeeService iEmployeeService;

@InjectMocks
ServiceCalendarViewBean serviceCalendarViewBean  = new ServiceCalendarViewBean();
@Test
public void testSaveEvent() {
    Mockito.when(iSecurityLoginService.findLoggedInUserId()).thenReturn(1);

    serviceCalendarViewBean.getEntityEventsCreate().setTitle("Junit Event Testing");

Mockito.when(iSecurityLoginService.findLoggedInUserId()).thenReturn(1);
Mockito.when(iEmployeeService.addEmployeeTimeOff(Mockito.any(Events.class))).thenReturn(2);

 serviceCalendarViewBean.addEvent();
}
