difference from backing bean and request scopes
The Fusion Dev. Guide report at 25.3 :
Request scope: The object is available from the time an HTTP request is made until
a response is sent back to the client.
Backing bean scope: Used for managed beans for page fragments and declarative
components only, the object is available from the time an HTTP request is made until
a response is sent back to the client.
Then I can't understand the real meaning of backing bean scope.
