Messaging in Seam
In Seam reference from CVS is :
Message-driven beans may even be Seam components, in which case it is possible to inject other event and application scoped Seam components.
But this not works. I get NPE when I send message to MDB annotated with @Name:
Caused by: java.lang.NullPointerException at org.jboss.seam.Component.forName(Component.java:1298) at org.jboss.seam.ejb.SeamInterceptor.getSeamComponent(SeamInterceptor.java:193) at org.jboss.seam.ejb.SeamInterceptor.postConstruct(SeamInterceptor.java:72) at sun.reflect.GeneratedMethodAccessor219.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.ejb3.interceptor.LifecycleInvocationContextImpl.proceed(LifecycleInvocationContextImpl.java:131) at org.jboss.ejb3.interceptor.LifecycleInterceptorHandler.postConstruct(LifecycleInterceptorHandler.java:105) ... 15 more
I have also problems with ManagedQueueSender it works but when Seam tries to destroy component it throws Exceptions:

Am I doing something wrong or this features do not work yet?
(Seam version from CVS)
