Hello,
i tried to follow your advise.
But after starting the app i get this exception:
11:26:34,437 ERROR org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/baz]: Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener

This is because i have not added the @Install annotation to the bean.
The corresponding code (the same in current cvs and seam 1.2.0)Patch1 in Initialization.java looks like

              if ( nameAnnotation!=null && nameAnnotation.value().equals(name) )
  |                {
  |                   Install install = clazz.getAnnotation(Install.class);
  |                   if ( install.value() )
  |                   {
  |                      className = null;
  |                   }
  |                }
  | 
If there is no @Install annotation the value of install is null and hence the npe.
After adding the @Install annotation i getCaused by: org.jboss.seam.RequiredException: In attribute requires non-null value: authorizationBean.protocolTemplate
  | 	at org.jboss.seam.Component.getValueToInject(Component.java:1887)
  | 	at org.jboss.seam.Component.injectAttributes(Component.java:1336)
  | 	at org.jboss.seam.Component.inject(Component.java:1163)
  | 
when trying to inject my bean with @In.
But @AutoCreate is set and i have added auto-create="true" to the definition

Here is the components.xml fragment
    <baz:protocol-template file-name="meinFile" auto-create="true"/>
  | 
What to do next?

Ciao,
Carsten
