Composite type annotations are not fired when validating the bean.
Neither in beanValidator nor in formBeanValidator.

@FromTo(from = "from", to = "to")
public class ValidationBean {
private Date from, to; // from must be before to
...
}

I'm attaching the sample project.

Q1) Why the FromTo validation is not fired by beanValidator or formBeanValidator?
Q2) Even if it is, how would I get the error message from msgs?
