Cache resolved value of javax.faces.VALIDATE_EMPTY_FIELDS

In UIInput.shouldInterpretEmptyStringSubmittedValuesAsNull() the resolved value of 'javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL' is cached in the application map. It might be worth doing the same for 'javax.faces.VALIDATE_EMPTY_FIELDS' in UIInput.shouldValidateEmptyFields():

private boolean shouldValidateEmptyFields(FacesContext context)
{
ExternalContext ec = context.getExternalContext();
Boolean validateEmptyFields = (Boolean) ec.getApplicationMap()
.get(VALIDATE_EMPTY_FIELDS_PARAM_NAME);

if (validateEmptyFields == null)
{
String param = ec.getInitParameter(VALIDATE_EMPTY_FIELDS_PARAM_NAME);

// null means the same as auto.
if (param == null)

{ param = "auto"; }

else

{ // The environment variables are case insensitive. param = param.toLowerCase(); }

if (param.equals("auto") && _ExternalSpecifications.isBeanValidationAvailable())

{ validateEmptyFields = true; }
else if (param.equals("true"))
{ validateEmptyFields = true; }

else

{ validateEmptyFields = false; }

// cache the parsed value
ec.getApplicationMap().put(VALIDATE_EMPTY_FIELDS_PARAM_NAME, validateEmptyFields);
}

return validateEmptyFields;
}
