Examples of com.vaadin.data.fieldgroup.FieldGroup.bind()

com.vaadin.data.fieldgroup.FieldGroup.bind()
Binds the field with the given propertyId from the current item. If an item has not been set then the binding is postponed until the item is set using {@link #setItemDataSource(Item)}.
This method also adds validators when applicable.
@param field The field to bind @param propertyId The propertyId to bind to the field @throws BindException If the property id is already bound to another field by this field binder


        final FieldGroup binder = new FieldGroup(item);
        binder.setBuffered(false);


        for (int i = 0; i < 2; ++i) {
            binder.bind(nameField, "name");
            binder.bind(ageField, "age");
            unboundField.setPropertyDataSource(unboundProp);


            assertTrue("No listeners in Properties", fieldsHaveListeners(true));
