public class FacesMessage extends Object implements Serializable
 FacesMessage represents a single validation (or other) message, which is typically associated with a
 particular component in the view. A FacesMessage instance may be created based on a specific messageId. The
 specification defines the set of messageIds for which there must be FacesMessage instances.
 
Application.getMessageBundle(). If non-null, locate the named ResourceBundle, using
 the Locale from the current UIViewRoot and see if it has a value for 
 the argument
 messageId. If it does, treat the value as the summary of the FacesMessage. If it
 does not, or if Application.getMessageBundle() returned null, look in the ResourceBundle named by the value
 of the constant FACES_MESSAGES and see if it has a value for the argument messageId. If it does, treat the
 value as the summary of the FacesMessage. If it does not, there is no initialization information for the
 FacesMessage instance.ResourceBundle hit is found for the
 {messageId}, look for further hits under the key {messageId}_detail. Use this value, if
 present, as the detail for the returned FacesMessage.summary and detail of the FacesMessage
