Michael Heinen commented on MYFACES-1714:
-----------------------------------------
It was not my intention to blame myFaces for implementing the spec, although I
opened this bug ;-)
I hoped that if this is reproduceable by myFaces developers and also seen as
probably a spec bug that someone could pass this to the spec team.
Anyway, how could I make a request to the JSF team?
Do you think that this is something that should be handled by JSF
implementations or by ajax frameworks ?

> Key: MYFACES-1714
> URL: https://issues.apache.org/jira/browse/MYFACES-1714
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 1.1.5
> Environment: tomcat 5.5.23
> myfaces 1.1.5
> tomahawk 1.1.5
> ajax4jsf 1.1.1
> Reporter: Michael Heinen
> Priority: Critical
> Attachments: validation.war

>
> There is a serious conversion/validation problem with JSF in combination with
> ajax..
> From my point of view this is a major show stopper for jsf applications in
> combination with ajax.
> Therefore I created a simple demo application and attach it to this issue.
> My form contains a few input fields for Strings, dates and a number. If an
> invalid format is entered then the submitted value is not erased and the page
> is rerendered with the entered value.
> This is working fine so far.
>
> The error occurs now if I click then another ajax command that forces a
> refresh of the invalid fields via ajax.
> I use an a4j:commandButton with ajaxSingle=true and surrounded this button by
> an a4j:region in order to process no input fields on serverside.
> The values that are bound via valueBinding to the inputFields are set to null
> or reinitialized in the invoked ActionListener.
> But the old invalid data from the previous request is rerendered on the page.
>
> This happens because the submitted values of the invalid inputFields are not
> null but still contain the old invalid data.
> Therefore the valueBinding is not evaluated in the getter.
>
> I can't set the submitted value to null in the converter because invalid
> values should be rerendered in case that a normal processing button (not
> cancel button) is clicked.
> Pls have a look at the demo application:
> Call ... faces/test.jsp
> 1) Enter some data
> (e.g name="twotest", startDate="01/01/70", endDate="01/01/70"
> message="hello" count=55)
> and click save
> Result: Everything works fine.The new object is rendered in the list
> 2) Enter invalid data
> (e.g. number=doh)
> and click save
> Result: conversion error "Count:": value is no valid number (don't know
> the correct english message)
> 3) Click create new
> Result: Field count does still contain the old value doh
>
> 4) Click Edit
> Result: Field count does still contain the old value doh
> The other fields are correctly initialized
>
> My first approach was to except submittedValue from stateSaving but this did
> not solve the problem..
