JSF doesn't attempt to validate fields which are empty. Hence trying to validate with @NotNull doesn't work.

So, in your example, if you had (with person.email being annotated with @Email)

<h:inputText value="#{person.email}" />

then, if you didn't enter a value, validation would pass, if you entered an invalid email address it would fail, if you entered a valid email address it would pass. If you added required="true" you would have to enter a value.

Seam can't fix this, a new JSF would be needed.
