Hi everyone!
I wanted to test some ajax validation on a simple form. But I noticed some strange behaviour for the following code:
<f:view>
 <rich:panel styleClass="pageMainpanel">
 <f:facet name="header">
 <ui:insert name="page.mainpanel.title">Panel-Titel</ui:insert>
 </f:facet>
 <h:form id="mainform">
 <rich:togglePanel switchType="ajax" stateOrder="stage1, stage2">
 <f:facet name="stage1">
 <h:panelGrid>
 <h:panelGrid columns="2" width="100px" columnClasses="formLabelClass, inputClass">
 <h:outputLabel value="Vorname" />
 <h:inputText value="#{customerBean.firstname}" id="firstname" required="true">
 <f:validateLength minimum="3"/>
 </h:inputText>
 <h:outputLabel value="Nachname" />
 <h:inputText value="#{customerBean.lastname}" id="lastname" required="true">
 <f:validateLength minimum="3"/>
 </h:inputText>
 <rich:messages ajaxRendered="true"/>
 </h:panelGrid>
 <a4j:outputPanel styleClass="toggleControl" layout="block" >
 <rich:toggleControl switchToState="#{'stage2'}" value="#{'stage2'}" />
 </a4j:outputPanel>
 </h:panelGrid>
 </f:facet>
 <f:facet name="stage2">
 <h:panelGrid>
 <h:outputText value="Stage 2" />
 <a4j:outputPanel styleClass="toggleControl" layout="block" >
 <rich:toggleControl switchToState="#{'stage1'}" value="#{'stage1'}" />
 </a4j:outputPanel>
 </h:panelGrid>
 </f:facet>
 </rich:togglePanel>
 </h:form>
 </rich:panel>
</f:view>
1) If I enter valid values the panel can be changed - fine! 
2) If I enter invalid values nothing happens. The tab seems to notice the validation error, but renders no messages at all. From now on you cannot change tabs anymore - even with values that are ok. 
Am I doing anything wrong? 
Thanks in advance, 
Oliver.
