/**
 * 

The presence of this annotation * on a class automatically registers the class with the runtime as a * {@link Converter}. The value of the {@link #value} attribute is * taken to be converter-id, the value of the {@link #forClass} * attribute is taken to be converter-for-class and the fully * qualified class name of the class to which this annotation is * attached is taken to be the converter-class. The * implementation must guarantee that for each class annotated with * FacesConverter, found with the algorithm in section * JSF.11.5, the proper variant of * Application.addConverter() is called. If * converter-id is not the empty string, {@link * javax.faces.application.Application#addConverter(java.lang.String,java.lang.String)} * is called, passing the derived converter-id as the first * argument and the derived converter-class as the second * argument. If converter-id is the empty string, {@link * javax.faces.application.Application#addConverter(java.lang.Class,java.lang.String)} * is called, passing the converter-for-class as the first * argument and the derived converter-class as the second * argument. The implementation must guarantee that all such calls to * addConverter() happen during application startup time * and before any requests are serviced.

*
*

The preceding text contains an important * subtlety which application users should understand. It is not * possible to use a single {@code @FacesConverter} annotation to * register a single {@code Converter} implementation both in the {@code * by-class} and the {@code by-converter-id} data structures. One way * to achieve this result is to put the actual converter logic in an * abstract base class, without a {@code @FacesConverter} annotation, * and derive two sub-classes, each with a {@code @FacesConverter} * annotation. One sub-class has a {@code value} attribute but no * {@code forClass} attribute, and the other sub-class has the converse.

*

Please see the ViewDeclarationLanguage documentation for {@code * } for another important subtlety regarding * converters and collections.
