[jboss-user] [jBPM] - Re: TwoPhaseCoordinator.beforeCompletion - Unknown node instance type

Maciej Swiderski [https://community.jboss.org/people/swiderski.maciej] created the discussion "Re: TwoPhaseCoordinator.beforeCompletion - Unknown node instance type" To view the discussion, visit: https://community.jboss.org/message/764319#764319 -------------------------------------------------------------- I think that the cause fo the problem is: Caused by: java.lang.NullPointerException     at org.jbpm.process.instance.impl.ProcessInstanceImpl.getProcess(ProcessInstanceImpl.java:68) that indicates you should use command to set the variables, try with following code: GenericCommand<Void> setProcInstVariablesCommand = new GenericCommand<Void>() {             public Void execute(Context context) {                 StatefulKnowledgeSession ksession = ((KnowledgeCommandContext) context).getStatefulKnowledgesession();                 ProcessInstance processInstance = ksession.getProcessInstance(new Long(processInstanceId));                 if (processInstance != null) {                     VariableScopeInstance variableScope = (VariableScopeInstance)                         ((org.jbpm.process.instance.ProcessInstance) processInstance)                             .getContextInstance(VariableScope.VARIABLE_SCOPE);                     if (variableScope == null) {                         throw new IllegalArgumentException(                             "Could not find variable scope for process instance " + processInstanceId);                     }                     for (Map.Entry<String, Object> entry: variables.entrySet()) {                         variableScope.setVariable(entry.getKey(), entry.getValue());                     }                 } else {                     throw new IllegalArgumentException("Could not find process instance " + processInstanceId);                 }                 return null;             }         };   ksession.execute(setProcInstVariablesCommand); HTH -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/764319#764319] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
