[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-2771) NPE in update call from wrong WM Entry Point

NPE in update call from wrong WM Entry Point -------------------------------------------- Key: JBRULES-2771 URL: https://issues.jboss.org/browse/JBRULES-2771 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.1.1.FINAL Reporter: Wolfgang Laun Assignee: Mark Proctor Fix For: 5.2.0.M2 This sequence of statements disagrees with the documentation: WorkingMemoryEntryPoint entryPoint = kSession.getWorkingMemoryEntryPoint( "epn" ); FactHandle fh = entryPoint.insert( fact ); kSession.update( fh, fact ); // should be done using entryPoint.update But this causes (in 5.1.1) a NPE Exception in thread "main" java.lang.NullPointerException at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1379) at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1338) at org.drools.impl.StatefulKnowledgeSessionImpl.update(StatefulKnowledgeSessionImpl.java:266) at event.Main.execute(Main.java:153) at event.Main.main(Main.java:164) This is the line: if ( this.maintainTms ) { status = ((InternalFactHandle) factHandle).getEqualityKey().getStatus(); } and similar code can be found in trunk, so I suppose this is still possible.
