[news.eclipse.platform] Binding the attribute of a bean object wrapped i

[d95776@xxxxxxxxx (Hao)]

I have a java bean such as Contact which has attributes such as name, 
address, email. The object presented to my code is a Wrapped WritableValue 
object, i.e. IObservableValue. 
For instance,
IObservableValue contactObservable = new WritableValue(new Contact(), 
Contact.class);

I tried to bind the name attributed of Contact bean wrapped in 
contactObservable to a text field. I did the following:

		IObservableValue bindedNameTextObserveWidget = 
SWTObservables.observeText(text);
		IObservableValue selectedContactNameObserveDetailValue = 
BeansObservables.observeDetailValue(Realm.getDefault(), contactObservable, 
"name", java.lang.String.class);

		bindingContext.bindValue(bindedNameTextObserveWidget, contactObservable, 
null, null);

I did not get any error but this kind of binding does not work.

Any one knows how to bind the attribute of a writableValue object to a gui 
field instead of binding the attribute of a java bean to a gui field.
