[jboss-jira] [JBoss JIRA] Assigned: (JBRULES-3145) Types declared in DRL with no fields are not included in KnowledgeBase compiled by ChangeSet

Types declared in DRL with no fields are not included in KnowledgeBase compiled by ChangeSet -------------------------------------------------------------------------------------------- Key: JBRULES-3145 URL: https://issues.jboss.org/browse/JBRULES-3145 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.2.0.Final Environment: Drools 5.2.0 Final, Guvnor 5.2.0 Final Reporter: John Fullard Assignee: Edson Tirelli 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) at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:65) at org.drools.common.NamedEntryPoint.createHandle(NamedEntryPoint.java:705) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:282) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:905) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:864) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:255) at john.DroolsError.runRules(DroolsError.java:48) at john.DroolsError.main(DroolsError.java:40) 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.
