Examples of org.apache.tapestry5.ValidationDecorator

org.apache.tapestry5.Validator
An object responsible for performing decorations around fields and field labels. The decorator is notified at intervals by the fields and labels.
In most western languages (written left to right) the label will render before the field, so the properties of the Field may not be set yet (or may reflect a previous looping's rendering). It may be necessary to {@linkplain org.apache.tapestry5.services.Heartbeat#defer(Runnable)} defer any rendering} until after the Label and the Field haveboth had their change to initialize and render.
Modern HTML and CSS, especially under HTML5 and CSS3, really makes this pointless; it is possible to handle all of these issues directly in the client. ValidationDecorator will be supported in Tapestry 5.4, but the default implementation will be changed to do nothing. @deprecated Deprecated in 5.4 with no replacement.
