Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.Create workitemhandler in JBDS as follows...
	public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {

		// extract parameters
		String snd_message = (String) workItem.getParameter("SecondMessage");
		System.out.println("Prabakar  ::: " + snd_message);
		
		Map<String,Object> results = new HashMap<String,Object>();
		results.put("Result", "Ak");
		
		manager.completeWorkItem(workItem.getId(), results);
	}
2.Update your workitemdefinition information as follows...
  [
    "name" : "SecondNotification",
    "parameters" : [
      "SecondMessage" : new StringDataType(),
    ],
  	  "results" :[
  	  "Result" : new StringDataType()
  	],
  	[
  	  "icon" : "com/icon/world.png",
  	  "displayName" : "Get"
  	]
3. Call the process in main method in JBDS
public static final void main(String[] args) {
try {
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieSession kSession = kContainer.newKieSession("ksession-process");			kSession.getWorkItemManager().registerWorkItemHandler("SecondNotification", new SecondWorkingHandler());
Map<String, Object> params = new HashMap<String, Object>();
params.put("MyResultParam", "Prabakar");
kSession.startProcess("com.sample.bpmn.hello", params);
			
        } catch (Throwable t) {
            t.printStackTrace();
        }
    }
