> Following came in from Markus B├╝ttner from the users list:
> <h:form id="myForm">
> <h:selectOneMenu id="selectMenu" value="#{myBean.menuValue}"
> valueChangeListener="#{myBean.menuValueChangedListener}">
> <f:selectItem itemValue="true" itemLabel="Yes"/>
> <f:selectItem itemValue="false" itemLabel="No"/>
> <f:ajax event="change" render="output"/>
> </h:selectOneMenu>
> <h:outputText id="output" value="#{myBean.menuValue}"/>
> <h:commandButton action="action"/>
> </h:form> 
> Switching from no to yes works, but switching from yes to no causes the
> following error messages in browser (firefox) and no request is send to
> server:
> clientError-TypeError-MyFaces ERROR:Affected Class:
> myfaces._impl.xhrCore._AjaxUtils
> Affected Method: encodeSubmittableFields
> Error name: TypeError
> Error message: subBuf is undefined
> Error description: undefined

> I tried to use boolean, String an enum Types for Value. But always the
> same error. 
> This is probably also the same bug Bruno Aranda has reported:
> I think a bug was introduced in the revision 960856 last 6th of July,
> in the _AjaxUtils class. A variable is initialized inside a loop, but
> is accessed outside. If the loop contains no values, the variable will
> be left undefined. This is the code, lines 196-207:
> if (element.options[u].selected) {
>                             var subBuf = [];
>                             var elementOption = element.options[u];
>                             subBuf.push(encodeURIComponent(name));
>                             subBuf.push("=");
>                             if (elementOption.getAttribute("value") != null) {
> subBuf.push(encodeURIComponent(elementOption.value));
>                             } else {
> subBuf.push(encodeURIComponent(elementOption.text));
>                             }
>                         }  strBuf.push(subBuf.join(""));
> subBuf is accessed outside the loop, but initialized inside. If there
> are no "options selected", subBuf will throw an 'undefined' javascript
> exception. I guess that subBuf should be initialized outside the loop?
