| This class provides a phase listener that removes all queued messages at
the end of the rendering phase. Normally, the message queue is cleared at
the start of the lifecycle. In a portlet context, however, the rendering
phase may be invoked repeatedly and messages will be redisplayed.
Especially in the case of error messages, it may be desirable to clear the
messages after a single display. If you want this behaviour, configure this
listener.
