Have any plans been finalized ?

I don't mind either way..

Our current soloution is a hibernate source hack to create a PersistentStringEnum class, and this sux when upgrading to newer hibernate versions.

Description:
Persistent String Enum
PersistentEnum type is a very userfull feature, but in 
the legacy data world it happens that some enumerations 
are stored in "char" columns instead of integer and, as 
far as I understood, I can map a persistent enumeration 
only with integer. 
Mapping my existing data I found several char(2) fields 
that would be nice to map with an enumeration. I tried 
to write a patch in order to manage such fields 
introducing a new Hibernate type 
PersistentStringEnumType and an interface 
PersistentStringEnum that one can use as the existing 
PersistenEnum interface. 

Please, find the modified classes (TypeFactory, 
MappingByReflection, Hibernate) and the new one 
(PersistentStringEnum, PersistentEnum) in the attached 
zip (for Hibernate 1.2) 

(BTW: Does someone know a simple way to make a patch 
against CVS?) 

It also contains a test case for the feature. The test 
sources explain how to use it.

The lenght of the field must be declared in the mapping 
through the attribute in the <property> tag. 
I would be nice if we could set it somewhere in the 
class that define the PersistentStringEnum, but I can't 
realize if it's possible.
