      Seam, JSF and EJB3 newbie
      Setup: Seam 2.0.2 SP1, Tomcat 6.0.x, XP SP3


      Goal: Trying to implement a4j actionListener for a selectOne menu
      I have 2 comboBoxes; some select combinations will make visible a a4j outPanel



      /login.xhtml declarations looks like this




      xmlns="http://www.w3.org/1999/xhtml"
      xmlns:s="http://jboss.com/products/seam/taglib"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
          xmlns:a="http://richfaces.org/a4j"
          xmlns:ui="http://java.sun.com/jsf/facelets"




      a4j code looks like this




      SRB AuthenticationScheme       *
                                          <h:selectOneMenu id="authSchemeMenu" value="#{loginBean.authenticationScheme}" required = "true">
                                                <!-- RAVI changing on 09/18/2008 -->
                                                <a:support event="onchange"  reRender="gssFieldsRegion" renderRegionOnly="true" actionListener="#{login.authorizationFieldsSetUp}"/>
                                                <s:selectItems value="#{loginBean.availableAuthenticationSchemes}" var="auth" label="#{auth}" />
                                                          </h:selectOneMenu>
                                                                    
                                        SRB DataTransferScheme  *
                                            <h:selectOneMenu id="dataTransferCombobox" value="#{loginBean.dataTransferScheme}" required = "true">
                                                <!-- RAVI changing on 09/18/2008 -->
                                                <a:support event="onchange"  reRender="gssFieldsRegion" renderRegionOnly="true"/>
                                                <s:selectItems value="#{loginBean.availableDataTransferSchemes}" var="dataTransfer" label="#{dataTransfer}" />
                                            </h:selectOneMenu>



      Login Interface Looks like this:


      @Local
public interface Login
{
    void authorizationFieldsSetUp();
    String login();
}




      Login Action Looks like this:


      @Name("login")
@Scope(SESSION)
public class LoginAction implements Login
{
   
   @In @Out
   private LoginBean loginBean;

....

public void authorizationFieldsSetUp()
   {
       log.debug("ENTER: authorizationFieldsSetUp()");
       if(loginBean != null)
       {
           String authenticationScheme =  loginBean.getAuthenticationScheme();




      Finally Exception Trace


      :
