Validation doesn't run for required fields if submitted value is null
---------------------------------------------------------------------
Key: MYFACES-1467
URL: http://issues.apache.org/jira/browse/MYFACES-1467
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 1.1.5-SNAPSHOT, 1.2.0-SNAPSHOT
Reporter: David Chandler
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.
