Label does not update when property is set manually

Vaadin 6 / 7 / 8 Framework Data Binding

Hello,

I have a Label and a InlineDateField. Both components have the same ObjectProperty as their PropertyDataSource.
When I change the date value using the InlineDateField component the Label changes the value shown correctly.

BUT, when I manually change the date after a Button click using the ObjectProperty only the InlineDateField is updated, the Label does not do it.

I have set both components to Immediate(true), and I have even manually markAsDirty each component.

Anyone can explain me why only the InlineDateField is updated. Why the label is not updated? How can I fix this?

date = new Date();
final Property<Date> property = new ObjectProperty<Date>(date);
label_1.setPropertyDataSource(property);
label_1.setImmediate(true);
inlineDateField_1.setPropertyDataSource(property);
inlineDateField_1.setImmediate(true);


button_1.addClickListener(new ClickListener() {

            private static final long serialVersionUID = 1L;

            @Override
            public void buttonClick(ClickEvent event) {

                property.getValue().setYear(10);

                inlineDateField_1.markAsDirty();
                label_1.markAsDirty();
            }
  });

Try this:
@Override
public void buttonClick(ClickEvent event) {
Date date = property.getValue();
date.setYear(2010);
property.setValue(date);
}

Or even better:
@Override
public void buttonClick(ClickEvent event) {
Calendar calendar = Calendar.getInstance();
calendar.setTime(property.getValue());
calendar.set(Calendar.YEAR, 2010);
property.setValue(calendar.getTime());
}
