[news.eclipse.platform] Re: [Databinding] Handle persistent & generation

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

I'm using master-detail support for this kind of things:

WriteableValue v = new WriteableValue();
v.setValue(new ModelObject());

IObservableValue model = BeanObserables.observeDetail(
   Realm.getDefault(),
   v,
   "attribute"
);
IObservableValue ui = SWTObservable.observeText(....);

... later on when I create a new object once more

v.setValue(new ModelObject());
