Comment:
simple case description for the Ajax/Jsf problem:
This version works (with a textbox):
<a4j:region renderRegionOnly="false">
<h:selectOneRadio id="choose" value="#{bean.a}">
<f:selectItems value="#{bean.map}" />
<a4j:support ajaxSingle="true" event="onchange" reRender="ajaxPanel" />
</h:selectOneRadio><br />
</a4j:region>
<a4j:outputPanel id="ajaxPanel">
<h:inputText id="myInput" value="#{bean.b}" rendered="#{bean.a == 'blue'}"
required="true" />
<h:message for="" />
</a4j:outputPanel><br />
Mandatory field:
<h:inputText value="#{bean.c}" required="true" /><br />
<h:commandButton value="submit" action="" />
This version fails in some cases with a Converter exception for the radiobutton control.
(the only change is the use of radiobuttons instead of a textbox)
<a4j:region renderRegionOnly="false">
<h:selectOneRadio id="choose" value="#{bean.a}">
<f:selectItems value="#{bean.map}" />
<a4j:support ajaxSingle="true" event="onchange" reRender="ajaxPanel" />
</h:selectOneRadio><br />
</a4j:region>
<a4j:outputPanel id="ajaxPanel">
<h:selectOneRadio id="myInput" value="#{bean.b}" rendered="#{bean.a == 'blue'}"
required="true">
<f:selectItems value="#{bean.map2}" />
</h:selectOneRadio>
<h:message for="" />
</a4j:outputPanel>
<br />
Mandatory field:
<h:inputText value="#{bean.c}" required="true" /><br />
<h:commandButton value="submit" action="" />
The exception is:
java.lang.IllegalArgumentException: Value is no String (class=org.apache.myfaces.shared_impl.renderkit.RendererUtils$1, value=org.apache.myfaces.shared_impl.renderkit.RendererUtils$[EMAIL PROTECTED]) and component myform:myInput with path: {Component-Path : [Class: org.ajax4jsf.framework.ajax.AjaxViewRoot,ViewId: /ajax.xhtml][Class: javax.faces.component.html.HtmlForm,Id: myform][Class: org.ajax4jsf.ajax.html.HtmlAjaxOutputPanel,Id: ajaxPanel][Class: javax.faces.component.html.HtmlSelectOneRadio,Id: myInput]} does not have a Converter
It looks like Jsf/Ajax tries to assign an invalid value (maybe a myfaces radiobutton control ?!) to the SelectOneRadio button.

After a review, the "update versions" field in the "Modify" tab of a note is not displayed.
