Hi, Some more research revealed that the entity beans managed by Hibernate (3.2.4) get proxies with classes like "<actual_entity_class_name>_$$_javassist_XXX" with the actual bean's class as a superclass (as tihomir noted!) and are correctly recognized by the Drools engine. But from what I saw JBoss Seam 2.2.0.GA actually uses Javassist and the session bean proxies end up with dynamically generated classes like "org.javassist.tmp.java.lang.Object_$$_javassist_seam_XXX" whose superclass is java.lang.Object (!) and when asserted as a fact such object is obviously not recognized by the Drools and corresponding rules do not fire. So it looks that there is a problem as Drools is unable to correctly recognize JBoss Seam components assigned as facts possibly due to the different way in which JBoss Seam creates proxies compared to Hibernate.
