The second milestone of the next MyFaces ExtVal release is available in the Apache snapshot repository.
In comparison to milestone 1, the Bean-Validation integration module was activated. Furthermore, some great new features are available as well.
The new validation module allows to use JSR 303 with all JSF versions. JSF 2.0 supports JSR 303 out of the box. Anyway, ExtVal offers advanced features beyond the standard integration (e.g. model-validation, severity aware validation and much more!).
Moreover, the new integration module offers some great features which are already known from the existing infrastructure of ExtVal.
One of these features is constraint based client-side validation in combination with MyFaces Trinidad.
Early adaptors can use the snapshots which are available
here.
