Description

JSF 2.0 has support for run validation on empty fields (which integrates with BeanValidation)

<quoteFromSpec>
javax.faces.VALIDATE_EMPTY_FIELDS – If this param is set, and calling
toLowerCase().equals("true") on a String representation of its value returns
true, all submitted fields will be validated. This is necessary to allow the model
validator to decide whether null or empty values are allowable in the current
application. If the value is false, null or empty values will not be passed to the
validators. If the value is the string "auto", the runtime must check if JSR-303 Beans
Validation is present in the current environment. If so, the runtime must proceed as if the
value "true" had been specified. If JSR-303 Beans Validation is not present in the
current environment, the runtime most proceed as if the value "false" had been
specified. If the param is not set, the system must behave as if the param was set with the
value "auto".
