Problem is that updateTask method does not update bpm:assignee property in HashMap which task object holds, the old value from previous task persists. What must I change within my code for this to work?
Oh yes, I'm working with Alfresco 2.1 …

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.
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!
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.

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:

Here's transition execution code:

/*TransactionService transactionService = AlfrescoServices.getTransactionService();
RetryingTransactionCallback<Object> work = new RetryingTransactionCallback<Object>() {

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 bpm
wner 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
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?
how did you assign a new actor?
please Itll be useful for me
