Wes Wannemacher updated WW-3022:
--------------------------------

    Fix Version/s: 2.2.x
       Issue Type: Improvement  (was: Bug)

This seems a bit of a fringe case... I mean, why wouldn't you have a message? I'm marking for version 2.2.x and as an improvement as I am not following the use-case.

> Broken both on annotation and XML validators. Empty messages worked 2.0 but not in 2.1 (Tested up to 2.1.6).
> This is annoying on ModelDriven actions, since you can't delegate validations to model object. (empty message crashes validation and non-empty message will be appended to the actual messages of models validators).
