olivier dupuy commented on WW-2065:
-----------------------------------

Hello,

I totally agree on the request.
It totally make sense to be able to use constants defined in the application or any other Java code instead.
This make the application much more flexible, easier to maintain (change the constant in one place and done) and much easier to test too as you can use the constants in your test.
The support for OGNL should be present in all the parameters of validation annotations and in XML validators

Vote for it.
