Using org.apache.isis.applib.value.DateTime on View Model (JAXB) always return Current DateTime

Dear All

On my JAXB VM I has a DateTime property as bellow

@Property(editing = Editing.ENABLED)
@Getter @Setter
public org.apache.isis.applib.value.DateTime isisDateTime;

When I click to change value on my UI, it always change my value to Current
DateTime.

I also try another types such as joda LocalDate, LocalDateTime... It still
the same.

So I create another setter to debug my code, then I see that my setter has
been called 3 times. First time it's correct value, but second and thirst
it change to current date.

My Question is, why it has been call many times? why it always change my
value?

Use @XmlTransient annotation on the injected service fields so that jaxb
ignores them.

This is just standard jaxb behaviour, there's nothing specific to Apache
Isis here.

Dear Dan Haywood

When I change to @XmlAccessorType(XmlAccessType.FIELD), I no longer be able
to Inject Service on my VM any more. It's another exception as bellow

Error marshalling domain object to XML, due to illegal annotations on
domain object class
'domainapp.modules.request.dom.vm.leaveform.LeaveFormVM'; 1 errors
reported:  org.apache.isis.applib.services.factory.FactoryService is an
interface, and JAXB can't handle interfaces.

If I use  @XmlAccessorType(XmlAccessType.PROPERTY)  it throw another
exception

Error marshalling domain object to XML, due to illegal annotations on
domain object class
'domainapp.modules.request.dom.vm.leaveform.LeaveFormVM'; 2 errors
reported: Class has two properties of the same name "leavingDate"; Class
has two properties of the same name "returningDate"

Thank so much for your quick respond, Now I use Joda LocalDate and
