[jboss-user] [JBoss Seam] - Seam + Ajax4Jsf == Exception?

[bkyrlach]

I'm trying to get a simple example app that uses ajax4jsf and seam together, but I'm getting a rather odd exception. Here's my xhtml snippet...

        <h:form>
          <h:inputText value="#{schoolListBean.name}">
            <a:support event="onkeyup" reRender="rep"/>
          </h:inputText>
          <a:outputPanel id="rep">
            #{schoolListBean.name}
          </a:outputPanel>
        </h:form>

Here's the bean...

@Stateful
@Name("schoolListBean")
@Scope(ScopeType.SESSION)
@Interceptors(SeamInterceptor.class)
public class SchoolListBeanImpl implements SchoolListBean, Serializable
{
    @PersistenceContext(unitName="schoolDatabase")
    EntityManager em;
    
    private String name;
    
    public List getSchools()
    {
        return em.createNativeQuery("SELECT * FROM WEBFRONT.COLLEGE_SEARCH_ENTITY WHERE COLLEGE_NAME LIKE '?%'").setParameter(1, name).getResultList();
    }

    public void setName(String name)
    {
        System.out.println("Setting name: " + name);
        this.name = name;
    }
    public String getName()
    {
        System.out.println("Getting name: " + this.name);
        return this.name;
    }

    @Remove @Destroy
    public void remove()
    {
        
    }
}

Everything works, but after every ajax request, the following is thrown to the console...
