Orbeon + jsf -> submit in selectonemenu - forms

Question

I have a problem with xforms, how refresh only rich:panel when I choose value from h:selectOneMenu :
<!--<h:form> call bean but--> <form><!--open start page-->
<h:selectOneMenu id="add" onchange="submit()" <!-- can't find context , error orbeon/java--> >
<!-- is not working <a4j:support event="onchange" actionListener="#{bean.action}"/> -->
<s:selectItems value="#{bean.List()}" var="message" itemValue="#{message}" label="#{message}" />
</h:selectOneMenu>
</form>
more Code JSF :
<form>
<rich:panel styleClass="DocumentBody" id="documentPanel"
name="panell" style="margin-top:10px; height:90px;">
<f:facet styleClass="documentHeader" name="header"></f:facet>
<div id="documentTest" class="actionButtons">
<div style="clear: both; height: 15px; width: 60px" />
<s:button id="addButton" value="#{messages['operation.save.button']}"
action="#{actionBean.generateNewName()}" reRender="confirm"
onclick="#{actionBean.generateNewName()};#{rich:component('confirm')}.show();return false;">
</s:button>
<s:button id="loadButton" value="#{messages['operation.load.button']}"
action="#{actionBean.loadDraft()}" reRender="documentTests,documentPanel,loadButton" />
<s:button id="deleteButton" value="#{messages['operation.delete.button']}"
action="#{actionBean.deleteDraft()}" reRender="documentTests,documentPanel,deleteButton" />
</div>
</rich:panel>
</form>
<h:form style="margin: 0;">
<h:selectOneMenu id="messageTypeAdd"
style="margin-right:5px; margin-top:-30px;margin-left:90px;"
valueChangeListener="#{actionBean.documentTestChange}"
enableManualInput="false" selectFirstOnUpdate="true"
directInputSuggestions="true" onchange="submit()">
<!-- submit() rerender all page, but i try refresh only modalPanel id="confirm" -->
<s:selectItems value="#{actionBean.getdocumentTestList()}"
var="message" itemValue="#{message}" label="#{message}" />
<!--a4j and f:ajax is not work, i try update JSF 1.2 to 2.0 -->
</h:selectOneMenu>
</h:form>
<rich:modalPanel id="confirm" autosized="true" width="300">
<f:facet name="header"></f:facet>
<rich:messages style="color:red;" globalOnly="true" />
<a4j:outputPanel ajaxRendered="true">
<h:panelGrid>
<h:panelGrid columns="2">
<h:outputText value="#{messages['report.name.label']}" />
<h:inputText id="newDraftNameInput" value="#{actionBean.newDraftName}"
valueChangeListener="#{actionBean.newDraftNameChange}">
</h:inputText>
</h:panelGrid>
</h:panelGrid>
</a4j:outputPanel>
</rich:modalPanel>
