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,
The UI could also let you decide whether the validation is model-bound
or code-bound and create relevant validateFor* methods perhaps or both?
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've often felt that WOLips could provide a view of validations taking
code & model into account. I think in the past you mentioned this was
difficult to do or couldn't be done.
