Examples of org.apache.tapestry5.NullFieldStrategy

org.apache.tapestry5.Validator
Defines a strategy, used by {@link Field} components such as {@link org.apache.tapestry5.corelib.components.TextField}, to handle the case where either the server-side value to be sent (as a string) to the client, or the client-side string passed back up to the server, is null or blank. @see org.apache.tapestry5.services.NullFieldStrategySource
