> A component with a required value will not fail validation as expected if the submitted
value is null. This issue is not seen normally because browsers send the value for an empty
text field as an empty string. That is, the POST data for an empty field1 will contain the
field name but no value, like field1=&field2=something. However, if you use a man-in-the-middle
proxy such as Paros to remove "fieldname=" from the POST data, the submitted value will be
null. UIInput.validate() skips validation for null submitted values, but since requiredness
is also part of validation, the requiredness check gets skipped, too.
