Hello
Yes, it is cayenne-1.2-dev-2006-4-11.
I'm sorry that I can't provide more info, but there is no Exception
thrown, the only symptom is that I'm getting a nulls where I should
get data.
I can add that I'm using an "wedge" class in between PersistentObject
and client entity classes. (Client superclass on cayenne modeler form)
I have a question too. Is it important to use same entity classes on
client and server ?
I would like not to import the client entity classes to server, but
generate them separately. I'm using superclass and custom dotemplates
what causes that whole client jar has to be added to server.
Aren't those classes treated as beans, so there is no real need to
have the same code on server and client ?
Regards
Marcin
