First cut is checked into SVN. If no problems, I'll add a couple more
features sometime. I especially want to add localization support for
GUI developers.
Thanks,

PS. Ari, I've never used ROP and I think you are the big ROP guy. If
you get a chance sometime, please test it a bit with ROP and let me
know if there are issues. Thanks!

Hi Marcin,
When I split up the enum type handling (standard versus extended) as
suggested by Andrus, I can clean up that EnumType<T extends Enum<T>>
bit, I think. The current EnumType which I checked in is supporting
two different types of enum, some of which implement
ExtendedEnumeration and some which do not, so I couldn't lock it down
to ExtendedEnumeration.
I believe for other custom extended types to auto-register themselves,
they'd have to implement an interface so Cayenne could map the values.
It has been a long time since I looked specifically at that. Perhaps
Andrus or another will correct me if I'm wrong on that matter. I'm
not saying it wouldn't be nice, though.
Thanks,
/dev/mrg

Hi
The EnumType will be very handy indeed. I've read the code and have a
couple of questions:
EnumType<T extends Enum<T>> made my head square and then round again,
I dont understand it. Wouldn't a simpler EnumType<T extends
ExtendedEnumeration> do ?
Would that be possible to make so all the ExtendedTypes (or just
EnumType) would be auto-registered in the Node ? I believe it could
be done during the configuration initialization or when the node is
first accessed. Right now all the extended types must be registered,
and if you forget to do so it will only come up when the
materializeObject() method lookup will fail (from my experience
setJdbcObject will work somehow using enum ordinal() and will not
throw any exception).
From different perspective: why would someone add a custom java type
as a attribute and not register it ? Maybe it should be another part
of the model/modeler where user defines available java types together
with their *Type classes ?
Best regards
Marcin
