[jboss-user] [jBPM] - Diagram not upadet (using async. work item)

Livia Hauser [http://community.jboss.org/people/liviah] created the discussion "Diagram not upadet (using async. work item)" To view the discussion, visit: http://community.jboss.org/message/630012#630012 -------------------------------------------------------------- Hi All, last weekend I played arround with drools (5.3.0.CR1) and  jbpm (5.1.1.Final) on jboss 5.1. I have a simple bpmn: [1]start -> [2] timer ->[3]script -> [4]AsyncHandler -> [5]timer -> [6]script -> [7]end After my AsyncHandler calls completeWorkItem task [5] and [6] will executed. But if I take a look at the diagram task [4] is still highlighted. How I can make shure a user will see right/updated diagram? My WorkHandler to test a asynch behavior: public class AsyncWorkItemHandler implements WorkItemHandler {      StatefulKnowledgeSession ksession;     public AsyncWorkItemHandler(ProcessContext kcontext){         super();         this.ksession = (StatefulKnowledgeSession)kcontext.getKnowledgeRuntime();     }     public AsyncWorkItemHandler(StatefulKnowledgeSession ksession) {         super();         this.ksession = ksession;    @Override    public void executeWorkItem(WorkItem workItem, WorkItemManager manager){         class WThread extends Thread{             int sessionId;             long itemId;             KnowledgeBase kbase;             Environment env;             public WThread(int sessionId,  long itemId,                     KnowledgeBase kbase, Environment env) {                 super();                 this.sessionId = sessionId;;                 this.itemId = itemId;                 this.kbase = kbase;                 this.env = env;             }             @Override             public void run(){                 int seconds = 30;                 System.out.println("thread for session " + this.sessionId + " (workitem "+ this.itemId +"), sleep " + seconds + "s");                 try {                     Thread.currentThread().sleep(seconds * 1000);                 } catch (InterruptedException e) {                     e.printStackTrace();                 }                 StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(this.sessionId, kbase, null, env);                 ksession.getWorkItemManager().registerWorkItemHandler("AsyncTask", new AsyncWorkItemHandler(ksession));                 ksession.getWorkItemManager().completeWorkItem(this.itemId, null);                 System.out.println("thread for session " + this.sessionId + " (workitem "+ this.itemId +") end");                 this.clean();             }                protected void clean(){                    this.kbase = null;                    this.env = null;             }         }         KnowledgeBase kbase = ksession.getKnowledgeBase();         Environment env = ksession.getEnvironment();         int sessionId = ksession.getId();         long itemId = workItem.getId();         WThread t = new WThread(sessionId, /*processId,*/ itemId, kbase, env);         t.start();       }     } } Any hints?
