    Value won't change

    J.R. Ector Newbie

      First let me explain what I trying to do.
      I'm using Seam 1.2 with Ajax4JSF and I'm trying to change the value of a selectOneMenu by using ajax on a selectOneRadio.
      The problem is that the value sent back never changes even as the value on the page is changed. Do you have to submit the page to get the value to change?

      Here's the relevant code:

      <f:view xmlns="http://www.w3.org/1999/xhtml"
       xmlns:s="http://jboss.com/products/seam/taglib"
       xmlns:ui="http://java.sun.com/jsf/facelets"
       xmlns:f="http://java.sun.com/jsf/core"
       xmlns:h="http://java.sun.com/jsf/html"
       xmlns:tr="http://myfaces.apache.org/trinidad"
       xmlns:rich="http://richfaces.ajax4jsf.org/rich"
       xmlns:a4j="https://ajax4jsf.dev.java.net/ajax">
      
       <html>
       <body>
      
       <h:messages globalOnly="true" styleClass="message" id="globalMessages" />
       <h:form id="vessel" styleClass="edit">
      
       <rich:panel>

       <s:decorate id="vesselIdDecoration">
       <h:inputHidden id="vesselId" disabled="#{vesselHome.managed}"
       value="#{vesselHome.instance.vesselId}">
       <a4j:support event="onblur" reRender="vesselIdDecoration" />
       </h:inputHidden>

      package gov.dot.marad.business.ejb;
      
      import gov.dot.marad.persistence.ejb.model.Shipyard;

      @Stateless
      @Name("shipyardFilter")
      public class ShipyardFilterAction implements ShipyardFilter
      {
       @Out
       private int statusId = 1;
      
       private List<Shipyard> shipyards;
      
       @In(create = true)
       EntityManager entityManager;
      
       @In
       VesselHome vesselHome;
      
      
       public EntityManager getEntityManager()
       {
       return entityManager;
       }
      
       public int getStatusId()
       {
       return this.statusId;
       }
      
       @SuppressWarnings("unchecked")
       @DataModel
       public List <Shipyard> getShipyards()
       {
      
       shipyards = getEntityManager().createQuery(
       " select shipyard from Shipyard shipyard " +
       " where shipyard.shipyardStatus.statusId=:status")
       .setParameter("status", getStatusId()).getResultList();
      
       return shipyards;
       }
      
      }
      


      I've tried various ways of using the @In annotation to no avail.
      Any help would be appreciated.
