+====== Data Binding of Nested Properties ======
+The data binding in Vaadin (since 7.x) is done with the FieldGroup class. But the FieldGroup does not support nested properties of Java Beans. There is a subclass BeanFieldGroup which does support nested properties.
+<sxh java>
+BeanFieldGroup<Customer> binder = new BeanFieldGroup<Customer>(Customer.class);
+binder.setItemDataSource(customer);
+...
+binder.bind(streetField, "address.street");
+</sxh>
