Actually, you don't need anything added to handle the serialization in
the case of enums - the toString() method is the default serialization
approach for all objects. You should be able to just define the
deserializer as the valueOf() method and leave the serializer defaulted.

I suppose I could generalize this to allow either static or member

Hi,
Yes, why do we need a STATIC serializer ?
A static method makes sense for a deserializer since we don't have an
instance at hand.
But I don't understand this restriction for a serializer, because in
that case we do have an instance ready.
This gets more frustrating when dealing with enums of Java 5.
Suppose we have an enum called Weekday.
* A natural deserializer is the pre-defined
Weekday.valueOf(String), and it works OK. valueOf is pre-defined
for every enum class.
* A natural serializer would be Weekday.toString(), which is NOT
accepted by the binder since it is not static. Why ???
The workaround is to explicitly define a static method as follows :
private static String serializer (Weekday day) { return
day.toString(); }
A bit awkward ...
Who could explain this ?
