All Implemented Interfaces:
PersistentFieldStrategy

The "flash" strategy stores data inside the session, just like SessionPersistentFieldStrategy, but also removes the values from the session on first use. In this way, a short-term value (such as an error message) will "survive" from an action request to a render request and then disappear.
