- /**
- * Defines the custom property name to be bound to a {@link Field} using
- * {@link FieldGroup} or {@link BeanFieldGroup}.
- * <p>
- * The automatic data binding in FieldGroup and BeanFieldGroup relies on a
- * naming convention by default: properties of an item are bound to similarly
- * named field components in given a editor object. If you want to map a
- * property with a different name (ID) to a {@link com.vaadin.client.ui.Field},
- * you can use this annotation for the member fields, with the name (ID) of the
- * desired property as the parameter.
- * <p>
- * In following usage example, the text field would be bound to property "foo"
- * in the Entity class. <code>
- * <pre>
- * class Editor extends FormLayout {
- @PropertyId("foo")
- TextField myField = new TextField();
- }
-
- class Entity {
- String foo;
- }
-
- {
- Editor e = new Editor();
- BeanFieldGroup.bindFieldsUnbuffered(new Entity(), e);
- }
- </pre>
- * </code>
