[JBoss Portal] - JSF Navigation issue with MyFaces 1.1.5
by SyedH
Hi,
I have an application running as a JSF portlet in my JBoss portal version 2.4.1 and JBoss AS 4.0.5 (myFaces version is 1.1.4).
I had some problems with the myFaces portlet version 1.1.4, so I replaced the myFaces 1.1.4 jars with myFaces version 1.1.5 jars in my JBoss AS (jsf-libs folder).
>From then I don't have my JSF navigation not working properly, like after clicking on a commandLink, it goes to the bean method, executes the business logic, returns a string matching my navigation rule, but my JSF page doesn't get changed, it stays in the same page.
I don't have this problem with myFaces version 1.1.4. I tried adding a JSF Phase tracker and found all the phases getting executed correctly in sequence.
Please help me with some inputs on this.
Thanks..

[EJB 3.0] - IllegalArgumentException on remove
by Quake4Ialdaris
Hey guys, I'm trying to remove an entity. here's the code
Entity class:
@Entity
public class NewsEntity implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String title;
private String body;
public NewsEntity() {
}
public Long getId() {
return this.id;
}
public void setId(Long id) {
this.id = id;
}
@Override
public int hashCode() {
int hash = 0;
hash += (this.getId() != null ? this.getId().hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object)
{
if (!(object instanceof NewsEntity)) {
return false;
}
NewsEntity other = (NewsEntity)object;
if (this.getId() != other.getId() && (this.getId() == null || !this.getId().equals(other.getId()))) return false;
return true;
}
public String getTitle()
{
return title;
}
public void setTitle(String title)
{
this.title = title;
}
public String getBody()
{
return body;
}
public void setBody(String body)
{
this.body = body;
}
}
Here's my facade interface:
@Stateless
public class NewsEntityFacade implements NewsEntityFacadeLocal
{
@PersistenceContext
private EntityManager em;
private Logger logger = Logger.getLogger (this.getClass ());
public NewsEntityFacade ()
{
}
public void create (NewsEntity newsEntity)
{
em.persist (newsEntity);
}
public void edit (NewsEntity newsEntity)
{
em.merge (newsEntity);
}
public void destroy (NewsEntity newsEntity)
{
em.merge (newsEntity);
if( em.contains (newsEntity))
logger.info ("The Entity is attached to current Persistence Context");
else
logger.error ("Entity is not attached!");
/* throws exception */
em.remove (newsEntity);
}
public NewsEntity find (Object pk)
{
return (NewsEntity) em.find (NewsEntity.class, pk);
}
public List findAll ()
{
return em.createQuery ("select object(o) from NewsEntity as o").getResultList ();
}
}
Here is the code that looks up the proxy and performs the delete operation:
NewsEntityFacadeLocal newsEntFacLocal = null;
try
{
InitialContext ctx = new InitialContext ();
newsEntFacLocal = (NewsEntityFacadeLocal)ctx.lookup
("NewsApp/NewsEntityFacade/local");
}
catch(Exception ex)
{
logger.error ("Error in looking up NewsEntityFacadeLocal through");
logger.error ("JDNI context " +JNDI_NEWS_ENTITY_EJB);
ex.printStackTrace ();
}
//this record exists in data store
NewsEntity ne = newsEntFacLocal.find (new Long(3));
logger.info ("the entity found is: " + ne.toString ());
nef.destroy (ne);
When I try this code I get an exception in the destroy method:
javax.ejb.EJBException: java.lang.IllegalArgumentException: Removing a detached instance ejb.NewsEntity#3

I can't see why it wouldn't be attached as the EntityManager javadocs say that merge attaches the entity in the PersistenceContext.
thanks
