[jboss-user] [jBPM Users] - Re: Variables keep old values

[aroeder]

I wrote a JUnit test for showing my problem:


  | package de.firstdata.test;
  | 
  | import java.io.IOException;
  | import java.util.HashMap;
  | import java.util.Map;
  | import java.util.Set;
  | 
  | import org.jbpm.graph.def.ProcessDefinition;
  | import org.jbpm.graph.exe.ProcessInstance;
  | import org.jbpm.taskmgmt.exe.TaskInstance;
  | 
  | import de.firstdata.config.TicketServiceConfigService;
  | import de.firstdata.dm.JBPMContextWrapper;
  | import de.firstdata.dm.TicketSystemDomainModelFacade;
  | 
  | public class JbpmVariablesTest extends ATicketServiceTestA {
  | 
  | 	private TicketSystemDomainModelFacade facade = null;
  | 
  | 	@SuppressWarnings("unchecked")
  | 	public void testVariables() throws IOException {
  | 
  | 		JBPMContextWrapper ctx = getContextWrapper();
  | 
  | 		try {
  | 			ProcessDefinition processDefinition = ProcessDefinition
  | 					.parseXmlString("<process-definition  xmlns=''  name='ABR'>" + "<start-state name='start-state1'>"
  | 							+ "<transition to='edit'></transition>" + "</start-state>" + "<task-node name='edit'>"
  | 							+ "<task name='edit'>" + "	<controller>"
  | 							+ "		<variable access='read,write,required' name='inbox'></variable>" + "	</controller>"
  | 							+ "</task>" + "<transition to='change' name='tochange'></transition>"
  | 							+ "<transition to='end-state1' name='done'></transition>" + "</task-node>"
  | 							+ "<task-node name='change'>" + "<task name='indexDataChange'>" + "	<controller>"
  | 							+ "		<variable access='read,write,required' name='inbox'></variable>" + "	</controller>"
  | 							+ "</task>" + "<transition to='edit' name='back'></transition>" + "</task-node>"
  | 							+ "<end-state name='end-state1'></end-state>" + "</process-definition>");
  | 
  | 			Map<String, String> myMap = new HashMap<String, String>();
  | 			myMap.put("inbox", "COMPLAINTS_MANAGEMENT");
  | 
  | 			ctx.deployProcessDefinition(processDefinition);
  | 			ProcessInstance processInstance = processDefinition.createProcessInstance(myMap);
  | 			ctx.save(processInstance);
  | 			processInstance.signal();
  | 
  | 			TaskInstance taskEdit = getTaskInstance(processInstance, "edit");
  | 			taskEdit.end("tochange");
  | 
  | 			ctx.save(taskEdit);
  | 
  | 			TaskInstance taskChange = getTaskInstance(processInstance, "indexDataChange");
  | 			Map<String, String> variables = taskChange.getContextInstance().getVariables();
  | 			variables.put("inbox", "CS_ISO");
  | 			taskChange.getProcessInstance().getContextInstance().addVariables(variables);
  | 			ctx.save(taskChange);
  | 			ctx.close();
  | 			ctx = getContextWrapper();
  | 
  | 			taskChange.end("back");
  | 
  | 			taskEdit = getTaskInstance(processInstance, "edit");
  | 			Map<String, String> changedVariables = taskEdit.getProcessInstance().getContextInstance().getVariables();
  | 
  | 			String inbox = (String) changedVariables.get("inbox");
  | 
  | 			taskEdit.end("done");
  | 			processInstance.end();
  | 			ctx.deleteProcessDefinition(processDefinition);
  | 
  | 			assertEquals("CS_ISO", inbox);
  | 		} finally {
  | 			ctx.close();
  | 		}
  | 	}
  | 
  | 	private JBPMContextWrapper getContextWrapper() {
  | 		if (facade == null) {
  | 			facade = (TicketSystemDomainModelFacade) TicketServiceConfigService.getConfig().getFacade();
  | 		}
  | 		return JBPMContextWrapper.getInstance("jbpm.cfg.xml", facade);
  | 	}
  | 
  | 	@SuppressWarnings("unchecked")
  | 	private TaskInstance getTaskInstance(final ProcessInstance processInstance, final String taskInstanceName) {
  | 		TaskInstance returnInstance = null;
  | 		Set<TaskInstance> tasks = (Set<TaskInstance>) processInstance.getTaskMgmtInstance().getTaskInstances();
  | 
  | 		for (TaskInstance ti : tasks) {
  | 			if (ti.getName().equals(taskInstanceName) && !ti.hasEnded()) {
  | 				returnInstance = ti;
  | 			}
  | 		}
  | 
  | 		return returnInstance;
  | 	}
  | }
