Hi,

I only need to update my model from the view not vice versa. Therefore I
would like to avoid to implement PropertyChangeListener support in my model.

I assume I can configure UpdateValueStrategy to tell the system that I
want to have only a one direction binding (only Ui to model). Can
someone point me in the right direction on how to do this?

Best regards, Lars

You want the PojoObservables coming with 3.4 which don't require
PropertyChangeListeners on the model side.

You should add it to the Data Binding Snippets page in the Eclipse Wiki:
