Andrus Adamchik commented on CAY-1213:
--------------------------------------
Andrei, I applied the patch. Looks good. One thing that I had to change is the
use of StringUtils. Looks like commons-lange library leaked into Cayenne via
Velocity, although Cayenne itself doesn't (and shouldn't) have a dependency on
commons-lang. So I replaced with with a simple 'indexOf' lookup, which should
also perform better, as it doesn't do cloning or regex matching, just a simple
substring.
> Cayenne should support enum types in qualifier statements/expression handling

> 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.
