--------------------------------

    Fix Version/s: 3.1M1
                       (was: Undefined future)
       Resolution: Fixed

Andrei, thanks for the patches. I applied them pretty much unchanged, and everything works correctly. 

A note on Cayenne code conventions (since I don't have any substantial comments on the actual patch contents :-)) - any new public or protected API (such as new methods), we tag with major Cayenne version when it was added. So I added "@since 3.1" to a few new public methods.

> Currently, cayenne doesn't support java enums in its expression syntax and, by extension, in qualifier statements.  This makes it impossible to use an enum type as a class descriminator for inheritance.
> Enum expressions would look like:
> propertyName = some.package.Type.CONSTANT
> to make it consistent with JPA.
