      Hi, folks!


      I'm a newbie in Seam, and I need some Help...I'm using:


      Eclipse with JBoss Tools
      JBoss 4.2.3GA
      Seam 2.0.1
      Hibernate3 with EJB container managed transaction



      I'm trying to use this:


      my page:


      <h:selectOneMenu id="select_mybject" value="#{myObject}">
    <s:selectItems value="#{myListofMyObject}" 
            var="myobject" label="#{myobject.name}" 
            noSelectionLabel="Select something"/>
    <s:convertEntity/>
                                        
</h:selectOneMenu>



      components.xml:



      <persistence:hibernate-session-factory name="sisgpSessionFactory" 
                                                                cfg-resource-name="/config/hibernate.cfg.xml"/>

        <persistence:managed-hibernate-session name="hibernateSession" 
                                auto-create="true"
                  session-factory-jndi-name="java:/sisgpSessionFactory"/>

        <transaction:hibernate-transaction session="#{hibernateSession}"/>

        <component name="org.jboss.seam.ui.EntityConverter">
                <property name="session">#{hibernateSession}</property>
        </component>



      my exception:


      org.hibernate.TransientObjectException: The instance was not associated with this session
