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

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.
