[jboss-user] [jBPM] - Re: MapBasedPersistenceTest issue

Donald Walters [http://community.jboss.org/people/dondragon2] created the discussion "Re: MapBasedPersistenceTest issue" To view the discussion, visit: http://community.jboss.org/message/633584#633584 -------------------------------------------------------------- I found the issue. I was using the drools MapPersistenceContext instead of the sample from https://github.com/krisv/jbpm/blob/master/jbpm-persistence-jpa/src/test/j... https://github.com/krisv/jbpm/blob/master/jbpm-persistence-jpa/src/test/j... But now I am getting the following error below sometimes. What could have caused this? java.lang.NullPointerException           at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.setState(WorkflowProcessInstanceImpl.java:251)           at org.jbpm.marshalling.impl.AbstractProcessInstanceMarshaller.readProcessInstance(AbstractProcessInstanceMarshaller.java:382)           at org.jbpm.persistence.processinstance.ProcessInstanceInfo.getProcessInstance(ProcessInstanceInfo.java:133)           at org.jbpm.persistence.processinstance.JPAProcessInstanceManager.getProcessInstance(JPAProcessInstanceManager.java:64)           at org.jbpm.process.instance.ProcessRuntimeImpl.getProcessInstance(ProcessRuntimeImpl.java:190)           at org.drools.common.AbstractWorkingMemory.getProcessInstance(AbstractWorkingMemory.java:1113)           at org.drools.impl.StatefulKnowledgeSessionImpl.getProcessInstance(StatefulKnowledgeSessionImpl.java:283)           at org.jbpm.persistence.processinstance.JPASignalManager.signalEvent(JPASignalManager.java:24)           at org.jbpm.process.instance.ProcessRuntimeImpl.signalEvent(ProcessRuntimeImpl.java:355)           at org.drools.impl.StatefulKnowledgeSessionImpl.signalEvent(StatefulKnowledgeSessionImpl.java:321)           at org.drools.command.runtime.process.SignalEventCommand.execute(SignalEventCommand.java:91)           at org.drools.persistence.SingleSessionCommandService.execute(SingleSessionCommandService.java:292)           at org.drools.command.impl.CommandBasedStatefulKnowledgeSession.signalEvent(CommandBasedStatefulKnowledgeSession.java:200) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/633584#633584] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
