How can you get field-validation to be handled completely by Bean Validation? I've tried various combinations of
<context-param>
javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL and javax.faces.VALIDATE_EMPTY_FIELDS but I never get required validation to work with @NotNull (without having to use required="true")
<param-name>javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>javax.faces.VALIDATE_EMPTY_FIELDS</param-name>
<param-value>true</param-value>
</context-param>
