I discovered interesting thing: "bpm:assignee" property is changed in the task, but this change is not visible if new WorkflowTask reference is not created.

WorkflowTask task = AlfrescoServices.getWorkflowService().getTaskById(taskId);

// change assignee property
updateProperties.put(WorkflowModel.ASSOC_ASSIGNEE, nrAssignee);
                
// update task
AlfrescoServices.getWorkflowService().updateTask(taskId, updateProperties, null, null);

WorkflowTask task2 = AlfrescoServices.getWorkflowService().getTaskById(taskId);‍‍‍‍‍‍‍‍‍

In task2 property map "bpm:assignee" property is set on new value.

But, nevertheless, if I execute a transition with signal, it behaves as if old assignee value is still valid. Very interesting, but frustrating. Please help!

I tried also the other approach to define different swimlanes with different actor variables for each of the tasks in series. Similar as with bpm:assignee, I can put update value in updateProperties hash map, but updateTask method does not update the task with key/value par. Of course, I get exception because task variable is not set:

Re: Assignee cannot be updated with updateTask in Java

joko71 — Thu, 07 Oct 2010 07:25:18 GMT

Haven't found a solution for my problems yet…

My serial workflow is working perfectly in Alfresco web client, I can assign new actor when I perform a task, but I can't do the same in Java code. Java method updateTask does not update task properties with the actor necessary for the next task.

Anyone?

Re: Assignee cannot be updated with updateTask in Java

I thought I solved this issue with a some kind of workaround, but it came back with a vengeance.

Still I cannot overwrite old bpm:assignee value with the new thru updateTask method. Signal on transition causes that task is delegated on the same user that created it.

Has anyone seen this behavior? Please help, I'm getting desperate…

Here's transition execution code:

   public static void executeTransition(final String taskId, String taskOwnerUsername, final String nrPackage, final String transitionId, final String assigneeUsername, final String comment, final String ticket) {
      
      /*TransactionService transactionService = AlfrescoServices.getTransactionService();
      RetryingTransactionCallback<Object> work = new RetryingTransactionCallback<Object>() {

         public Object execute() throws Throwable {*/
            
            NodeRef nrUser = Authentication.getInstance().getUserNodeRef(ticket);
            String userName = DefaultTypeConverter.INSTANCE.convert(String.class, AlfrescoServices.getNodeService().getProperty(nrUser, ContentModel.PROP_USERNAME));
            
            WorkflowTask task = AlfrescoServices.getWorkflowService().getTaskById(taskId);
            
            // update map
            Map<QName, Serializable> updateProperties = new HashMap<QName, Serializable>();
            
            // comment
            if(comment != null) {
               updateProperties.put(QName.createQName(BPM_DESCRIPTION_QNAME), comment);
            }
            
            // package
            if(nrPackage != null) {
               updateProperties.put(WorkflowModel.ASSOC_PACKAGE, new NodeRef(nrPackage));
            }
            
            // TODO: due date
            // parameters.put(WorkflowModel.PROP_DUE_DATE, dueDate);

             // assignee node reference
             NodeRef nrAssignee = AlfrescoServices.getPersonService().getPerson(assigneeUsername);

             if(nrAssignee != null) {
                //updateProperties.put(WorkflowModel.ASSOC_ASSIGNEE, assigneeUsername);
                updateProperties.put(WorkflowModel.ASSOC_ASSIGNEE, nrAssignee);
                
                updateProperties.put(ContentModel.PROP_OWNER, assigneeUsername);
                
               // auth 1 begin
               net.sf.acegisecurity.Authentication auth = AuthenticationUtil.setSystemUserAsCurrentUser();
               
                // update task
                AlfrescoServices.getWorkflowService().updateTask(taskId, updateProperties, null, null);
                
                // execute task
                String pathId = task.path.id;
               AlfrescoServices.getWorkflowService().signal(pathId, transitionId);

               NodeRef nrCompanyHome = getCompanyHomeNodeRef();
               AlfrescoServices.getPermissionService().setPermission(nrCompanyHome, userName, PermissionService.COORDINATOR, true);
               AuthenticationUtil.setCurrentUser(userName);
               // auth 1 end
                               
               // auth 2 begin
               AuthenticationUtil.setSystemUserAsCurrentUser();
               AlfrescoServices.getPermissionService().deletePermission(nrCompanyHome, userName, PermissionService.COORDINATOR);
               AuthenticationUtil.setCurrentUser(userName);
               // auth 2 end
             }

            /*return null;
         }
      };
      
      transactionService.getRetryingTransactionHelper().doInTransaction(work);*/
   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I solved the problem, so this thread can be closed.

It seems that I approached this problem wrong way. My assumption that I have to set properties first before updateTask was wrong. Right approach is to signal task first, then from path end old task with endTask, and then update new task from path, especially with bpmwner value which will transfer task to the new owner.

" Right approach is to signal task first, then from path end old task with endTask, and then update new task from path, especially with bpmwner value which will transfer task to the new owner."

I didn't get above clarification, can you explain it in more detail.

Thanks in Advance
