automatic persitence on RENDER_RESPONSE

[christophe.laumond]

Hi,

I have something like

@Entity
public class Question implements java.io.Serializable {

@OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "question")
 public Set<Answer> getAnswers() {
 return this.answers;
 }

Before rendering I add Answer instance to the above Set but I don't want to persist them, I just need them in order to retrieve value fromt the UI and according to the value i will persist some of them and discard some others.

But on the render response event I got the following stacktrace :

2006-09-28 14:07:53,984 DEBUG [org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener] committing transaction after phase: RENDER_RESPONSE(6)
2006-09-28 14:07:53,984 DEBUG [org.jboss.seam.util.Naming] JNDI InitialContext properties:{java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory, java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces}
2006-09-28 14:07:53,984 DEBUG [org.hibernate.event.def.AbstractFlushingEventListener] processing flush-time cascades

and all the Answer instances are persisted !

It looks like method like save() or update() are called automatically during this phase.

I would like to prevent this and understand why this happens.

Is this related to my faces-config file lifcycle tag :

<lifecycle>
<phase-listener>org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener</phase-listener>
</lifecycle>

thanks in advance for your feedback

Regards,
Christophe

I suggest you read up on Container Manager Persistence - both on the forum and the reference manual. Entities will be flushed on method boundaries unless stopped (FlushMode or TransactionAttribute).

Thanks for your feedback.

I have looked into the documentation and have a better understanding now.
