Mike Kienenberger commented on MYFACES-1741:
--------------------------------------------
There's a much better chance of getting discussion on this issue if you post a
message to the dev mailing list rather than adding comments to the issue. If
it's broad enough to include the JSF RI, you probably should cross-post between
the jsf ri dev mailng list and the myfaces dev mailing list.
> JSR-252 Issue 21 - Provided an additional "binding" attribute for the core
> Converter, Listener and Validator tags has wrong behaviour
> -------------------------------------------------------------------------------------------------------------------------------------
>
> Key: MYFACES-1741
> URL: https://issues.apache.org/jira/browse/MYFACES-1741
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-252
> Affects Versions: 1.2.0
> Environment: Tomcat 6.0.14, Myfaces 1.2.1-SNAPSHOT (Oct 7 2007)
> Reporter: Leonardo Uribe
> Fix For: 1.2.1-SNAPSHOT
>
>
> There is a problem with the behaviour of binding attribute from
> actionListeners, validators and converters.
> I have this test. The objective is explore how binding attribute is doing
> things comparing jsf ri 1.2 and
> myfaces 1.2.1-SNAPSHOT, trying to detect bugs on myfaces :)

> QUESTION 2: Why I not have bindings assigned before INVOKE_APPLICATION ?(in
> this time is of value have a binding attribute) .
> Again JSF RI has the correct behaviour and Myfaces is wrong. Myfaces create
> the validators, converters and
> actionListeners on correct time, but not assign bindings when is supposed to
> do. If I assign a binding for
> converter, validator or actionListener, I should be assigned minimum before
> INVOKE_APPLICATION, or better,
> converters and validators on PROCESS_VALIDATIONS, and actionListeners in
> INVOKE_APPLICATION.
> Looks a little bit difficult but I will try to find a solution for this issue.
