> Setting up KnowledgeBase using KnowledgeAgent which is pulling package from Guvnor.  DRL declares type, which already exists in client model, with @role(event) and no fields.  Get the following stack trace when inserting an object:
> java.lang.NullPointerException 
>         at org.drools.reteoo.ReteooFactHandleFactory.newFactHandle(ReteooFactHandleFactory.java:56) 
>         at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:80)

> If the type is fully declared in the DRL, the NPE does not occur.
> When compiling a DRL from a Change Set, the resulting package in the Knowledge Base does not contain declare'd types that do not contain fields; it only contains declares with at least one field. This results in a ClassObjectTypeConf with a typeDecl == null.
