    [ https://jira.jboss.org/browse/RF-8744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12534721#action_12534721 ] 

Anton Belevich commented on RF-8744:
------------------------------------

Not a behavior bug. line 602: "parameters[sourceId] = sourceId" in richfaces.js cause of this bug. UISelectOne or UISelectMany components use context.getExternalContext().getRequestParameterValuesMap() method to retrieve values from the request;  So in component 'submittedValue' will be chosen values from SelectItem  hidden inputs +  component client id thus fails validation during validateValue method execution.

> The following code doesn't work as expected (output is not updated). When a4j:ajax is changed to f:ajax, everything works. The same problem exist in selectManyMenu and selectManyListbox.
> <h:selectManyCheckbox id="selectManyMenu" value="#{richBean.cars}" > 
>     <f:selectItem itemValue="Audi" itemLabel="Audi"/>
>     <f:selectItem itemValue="Mercedes" itemLabel="Mercedes"/>
>     <f:selectItem itemValue="Ferrari" itemLabel="Ferrari"/>
>     <f:selectItem itemValue="Lexus" itemLabel="Lexus"/>
>     <f:selectItem itemValue="BMW" itemLabel="BMW"/>
>     <a4j:ajax event="change" execute="@form" render="output"/>
> </h:selectManyCheckbox>
> <a4j:outputPanel id="output">Your selection: #{richBean.cars}</a4j:outputPanel>
