3. Hibernate validators are not too bad for basic validations
I've always felt that EOF should have more out-of-the-box model-
defined validation support
I'm not so sure about EOF doing this -- I quite like being able to
organise this in-code and I think it is one of those things that
something like PW can add-on without having to put too much into
the basic frameworks.
Admittedly, validation in the model is a bit of a religious debate.
I think there's a lot of value that can be derived by model-defining
it in that you can things like have the UI automatically do richer
validation without custom-coding it, and if they're written
declaratively, you can actually generate client-side validations
that don't require a server roundtrip to just tell the user that you
aren't allowed to say you have more than 25 children (or whatever).
Anjo, I believe, is also adamantly against model-based validations
too, though. I don't know if this helps or hurts your case ;)
I don't think that the two are mutually exclusive. In such a situation
it is plainly better to have more options.
