GET method on 'http://localhost:8080/instance/{instanceId}/variables'

will return:

And the process instance flow chart will shows each tasks running states:

• if the task is running, the activity's background would be blinking.
• if the task is done, a completed badge (check) would be marked on the activity box.
• if the task is skipped, a skipped badge would be marked and so on.

박과장님,

프로세스 디자이너를 완성 한 후 할일:

1. 프로세스 디자이너에서 '실행' 버튼을 클릭하면, /definition/{defId}.json/instance 를 POST 하여 instance 를 발행합니다. POST 의 return 값이 instanceId 임.
2. 실행이 되면, 프로세스 디자이너는 해당 인스턴스에 대한 진행상태를 보여주는 화면으로 전환됩니다. (혹은 팝업?) 진행상태는 위의 InstanceService 를 호출하여 얻어낸 각 액티비티의 상태값에 대한 key/value 값을 기반으로 진행상태를 보여주면 됩니다.

a pseudo code goes like follows:

var variables = serviceLocator.invoke({method: 'POST', path: '/instance/' + instId + '/variables'});

for(var activity in activities){
   var status =  variables[activity.tracingTag + ":_status:prop"];
   if(status == "Completed"){
        activityShape.markCompleted();
   }else if(status == "Running"){
        activityShape.markRunning();
   }else...
}
