Hello everybody,

I have problem with tree component. I build my tree dynamically (add node after clicking on a command button) and the problem is that the tree doesn't rerender after clicking. Of course I am using AJAX.

page.xhtml

<ui:define name="body">
    <h:panelGrid columns="1" id="leftPanel">
        <h:panelGroup>
            <a4j:commandButton action="#{treeBuilder.add}" value="+" reRender="tree"/>
            <a4j:commandButton action="#{treeBuilder.delete}" value="-" reRender="tree"/> 
            <a4j:commandButton action="#{treeBuilder.moveUp}" value="up" reRender="tree"/>
            <a4j:commandButton action="#{treeBuilder.moveDown}" value="down" reRender="tree" /> 
        </h:panelGroup>
        <a4j:outputPanel id="tree">
            <rich:tree switchType="ajax" value="#{treeBuilder.root}" nodeSelectListener="#{treeBuilder.processSelection}" ajaxSubmitSelection="true" var="node" ajaxKeys="#{null}" />
        </a4j:outputPanel>
     </h:panelGrid>
</ui:define>

That all is inside <h:form> ... </h:form>.

Thanks for help.
