"calling the setVariable on reloaded ProcessInstance leads to NullPointerException" To view the discussion, visit: https://community.jboss.org/message/800555#800555 -------------------------------------------------------------- Hi, at some point in my application I reload my session: JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, config, env); then my process instance: WorkflowProcessInstance processInstance = (WorkflowProcessInstance) ksession.getProcessInstance(processInstanceId); and then try to set a process variable: processInstance.setVariable(name, value) which fails : java.lang.NullPointerException at org.jbpm.process.instance.impl.ProcessInstanceImpl.getProcess(ProcessInstanceImpl.java:68) at org.jbpm.process.instance.impl.ProcessInstanceImpl.getContextInstance(ProcessInstanceImpl.java:133) at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.setVariable(WorkflowProcessInstanceImpl.java:238) ... The reason is: the variable InternalKnowledgeRuntime kruntime in ProcessInstanceImpl is null. Is it a bug or is there another way to load the process instance?
