[jboss-user] [JBoss Seam] - POJO with conversational scope

[joris77]

I have a POJO that i want to use as a Seam bean with conversational scope and I have an entity "Person" that I store as an instance variable/javabean property on that POJO. Like this ...


  | ...
  | @Name("depot")
  | @Scope(ScopeType.CONVERSATION)
  | public class Depot {
  | 
  | 	@Logger
  | 	private Log log;
  | 	
  | 	private Person person;
  | ...

What I expect is that if the instance variable is set after the first request (I do that in my code) of the conversation that it remains there until the conversation is ended by the @End annotation of one of depot's action methods.

Is this correct?

In reality after the first postback from the client the instance variable is null.

If I take a look in my logging I see that my javabean is created and destroyed each request:

I am afraid I am missing the point here, somebody explain me how conversations are supposed to work?

Do POJO conversations differ from EJB conversations?

Thanks anyway,
