For the sake of completeness: During serialization all properties of an object get serialized. Therefor they need to implement the interface Serializable. If they don't, then you need to make them "transient". Like this they are omitted during serialization and get re-injected after deserialization. In this case it makes sense, since faces, application or session contexts are "dynamic" and they might have changed in the meantime. So it's important to get the "newest" instance.
