Hello,

How raising an Event from an Asynchronous method?
Basically:

newSessionBean.java

...
 public String step1()
 {
 sessionVisu = new SessionVisu(sessionVisu, user);
 sessionVisu.setStatus("description");
 computeHandler.processGetComputes(sessionVisu);
 return "/sessions.xhtml";
 }
...

ComputeHandlerBean.java

...
@Asynchronous
public void processGetComputes(SessionVisu sessionVisu){
 try {SECONDS.sleep(30);}
 catch(InterruptedException ignore){}
 sessionVisu = entityManager.merge(sessionVisu);
 sessionVisu.setStatus("compute");
 entityManager.persist(sessionVisu);
 events.raiseTransactionSuccessEvent("flushComputeSessionVisus");
 }
...

SessionVisuListBean.java

...
 @Factory
 @Observer("flushComputeSessionVisus")
 public void getComputeSessionVisus()
 {
 computeSessionVisus = entityManager.createQuery("select s from SessionVisu s where s.user.username = :username and s.status = :status")
 .setParameter("username", user.getUsername())
 .setParameter("status", "compute")
 .getResultList();
 }
...

The idea is to have a portlet "polled" by Ajax4jsf.
I used in my componentd.xml

<framework:entity-query name="sessionVisuCompute">
 <framework:ejbql>from SessionVisu s</framework:ejbql>
 <framework:restrictions>
 <value>user_id = #{userComp.id}</value>
 <value>status = #{sessComp.status}</value>
 </framework:restrictions>
 </framework:entity-query>

 <component name="userComp" class="User">
 <property name="id">#{user.id}</property>
 </component>
 <component name="sessComp" class="SessionVisu">
 <property name="status">compute</property>
 </component>

But i really wish to use the event/observer mechanism.

Any idea?

Thank you
