[news.eclipse.platform] Re: how to use databinding to bind dynamic data

[d95776@xxxxxxxxx (hao)]

Let me explain what I am trying to ask:

For example, I have a model called Contact which has a name attribute. The 
name field of the Contact is binded to a GUI text field called nameText. 
When the GUI class is constructed, the following is called:

private Contact contact;
private Text nameText;
private DataBindingContext bindingContext;

...
//In constructor

		IObservableValue contactNameObserveValue = 
BeansObservables.observeValue(contact, "name");
		IObservableValue nameTextTextObserveWidget = 
SWTObservables.observeText(nameText, SWT.Modify);
		bindingContext.bindValue(nameTextTextObserveWidget, 
contactNameObserveValue, null, null);


For some reason, during the operation of the application, the contact 
object is replaced with a new contact object. (Not the property name of 
the contact object is changed but contact object itself is changed.) How 
could I rebind the newly created contact object to nameText object?

thanks!
