Date Thu, 25 Dec 2008 10:35:36 GMT
conversion error should short-circuit all validators 
-----------------------------------------------------

                 Key: WW-2934
                 URL: https://issues.apache.org/struts/browse/WW-2934
             Project: Struts 2
          Issue Type: Bug
          Components: Core Interceptors
    Affects Versions: 2.1.2, 2.1.1, 2.1.0, 2.0.14, 2.0.13, 2.0.12, 2.0.11.2, 2.0.11.1, 2.0.11,
2.0.10, 2.0.9, 2.0.8, 2.0.7, 2.0.6, 2.0.5, 2.0.4, 2.0.3, 2.0.2, 2.0.1, 2.0.0
            Reporter: Noel Hernández
            Priority: Critical


If there is an error converting a field, the validators for that field should be skipped.
For example, let's say I have an action with an "age" field declared as an Integer, and the
field is required. If the user enters "one", the user will see two errors: one from the conversion
process, and one from the required validator (since the field was never assigned).

In general, a conversion error should short-circuit all validators for that field, since validators
depend on the field being set, which never happens if there was a conversion error.

Validators are essential for real world projects, this is a big issue with struts2.

look at stripes framework for a good designed validator framework.
