[rules-users] drools 5.0.1 generating fact types as non-serializable classes

Hello, I have declared a fact type in a drl file: package com.innovativeinfo.amacus.drools.model declare AmacusUser id : long timeZone : String end which according to http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/ht... should result in a generated class that implements Serializable. However when I try to persist the KnowledgeSession, I get: Caused by: java.io.NotSerializableException: com.innovativeinfo.amacus.drools.model.AmacusUser at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:302) at org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy.write(SerializablePlaceholderResolverStrategy.java:37) at org.drools.marshalling.impl.OutputMarshaller.writeFactHandle(OutputMarshaller.java:278) at org.drools.marshalling.impl.OutputMarshaller.writeFactHandles(OutputMarshaller.java:242) at org.drools.marshalling.impl.OutputMarshaller.writeSession(OutputMarshaller.java:85) at org.drools.marshalling.impl.DefaultMarshaller.marshall(DefaultMarshaller.java:117) at org.drools.persistence.session.JPASessionMarshallingHelper.getSnapshot(JPASessionMarshallingHelper.java:76) Is there a configuration option I need to set to generate Serializable fact types? Or is this a bug in 5.0.1? I realize I can define "fact types" myself as classes in Java, but would prefer to use the shortened syntax if possible. Any advice appreciated.
