Long running conversation

[ristretto]

I have this Seam POJO Action

@Name("bean")
@Scope(ScopeType.CONVERSATION)
@Conversational
public class BeanAction implements Serializable
{

@Begin(join=true)
@Create
public void create(){
log.debug("Starting Conversation id: "+ Conversation.instance().getId()+" long running?: "+Conversation.instance().isLongRunning());
}

When I browse bean.xhtml (facelets/jfc), the log says

Starting Conversation id: 1 long running?: false

Why false, thought it should be true?

And, when I submit a form on the page like this

<h:commandButton value="Submit to Method" action="#{bean.method}">
<s:conversationPropagation type="join"/>
</h:commandButton>

I get an exception saying my bean isn't in the context. And it seems that the conversation isn't available, which would make sense if it truely isn't long running, right? I'm quite confused, so my message may be lacking information to totally make sense. If so, ask questions.

It might be that the conversation is promoted to long-running later in the lifecycle (after the debug statement). Tried putting output on the view?

But I can't really say why the "bean" isn't picked up. It should be there, since conversation=request if it's not long running. The @Conversational might complain, but the bean should still be found(?).

Why false, thought it should be true?

The promotion to long running occurs after your method returns.

Is the bean deployed at startup?

Is the bean deployed at startup?

I believe so. In any case this was related to the JSF binding issues you pointed out in another thread.
