[jboss-user] [JBoss Seam] - Re: begin method invoked from a long running conversation, t

[MSchmidke]

It seems I'm doing something completely wrong. I discovered that the stateful session conversation context bean is created several times during rendering of the single request.

Here the debug output:

This is the first attempt to access the Seam Component named "leistungsschein". It isn't there, it is created, everything is fine.


  | 2006-07-20 15:14:32,177 DEBUG [org.jboss.seam.jsf.SeamVariableResolver] resolving name: leistungsschein
  | 2006-07-20 15:14:32,177 DEBUG [org.jboss.seam.Component] instantiating Seam component: leistungsschein
  | 2006-07-20 15:14:32,177 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}
  | 2006-07-20 15:14:32,177 DEBUG [org.jboss.ejb3.entity.ExtendedPersistenceContextPropagationInterceptor] ++++ LongLivedSessionPropagationInterceptor
  | 

Afterwards, lots of successful lookups like this:

  | 2006-07-20 15:14:33,224 DEBUG [org.jboss.seam.jsf.SeamVariableResolver] resolving name: leistungsschein
  | 2006-07-20 15:14:33,224 DEBUG [org.jboss.seam.contexts.Contexts] found in conversation context: leistungsschein
  | 
This all takes place during RENDER_RESPONSE and matches the EL calls to the Seam component in the page.

But then, suddenly:

  | 2006-07-20 15:14:33,912 DEBUG [org.jboss.seam.interceptors.RemoveInterceptor] Stateful component was removed: leistungsschein
  | 
Seam intercepts that the container has decided to remove the bean. What follows is clear - Seam recreates the bean, runs into @Begin method and complains about the already begun conversation.

But why does the container decide to remove the stateful bean??

I fear that it's an absolute beginner's error. But, in fact, I am an absolute beginner. Hope it's allowed to make some.

Regards,

Marcus.
