I have the following code...

<s:decorate id="navigateDec" template="../../web/zlogin/errorTemplate.xhtml">
     <ui:define name="label">Question:</ui:define>
     <h:selectOneMenu value="#{editScript.nextNode}">
            <s:selectItems value="#{pathActions.nodeSelectionList}" var="node" label="#{node.name}" noSelectionLabel="Please Select..." />
         <s:convertEntity />
     </h:selectOneMenu>
     <h:commandButton id="goToNode" value="Navigate to Question" action="#{editScript.changeCurrentNode()}"/>
</s:decorate>  
                                  <s:convertEntity />
                              </h:selectOneMenu>


        @In @Out
        private Node node;
        private Node nextNode;
     public Node getNextNode() {
          return nextNode;
     }
     public void setNextNode(Node node) {
          this.nextNode = node;
     }
     public void changeCurrentNode() {
          node = nextNode;
          nextNode = null;
          mgr.flush();
     }

The commandButton works great but I would like to get rid of it such that the user just selects from the pull down and no button click is needed.  I tried adding onchange="submit();" but that doesn't work as changeCurrentNode is not called, so then I added a valueChangeListener which fails because then changeCurrentNode is called BEFORE the apply values to model phase.  I want a method called after values have been applied to the model.  How do I do such a thing?

I basically need node to be set to nextNode and outjected from the pojo to the context BEFORE the next page is rendered.
thanks for any help on this,
Dean
