Assign Task to Multiple Users

PostPosted:Tue Feb 03, 2015 9:55 am

Hi,
Is it possible to assign a task to a group of users - want all the users in the group to review a particular document.

Tried using 'pooledActors', but in this case the task is being picked up by only ONE person in the group.
On the other hand, would like all the members in the group to be assigned to a task.

Appreciate any help in this regard.
Thanks,
Vasu

Seems parallel revision. The number of users to review will be always the same ? and the reviewers will be always the same ?

Hi jllort,
Yes, looking for parallel revision.
The number of reviewers will change.
The reviewers will also change.

Used 'Fork/Join' and was able to assign a document to 2 members parallely (attached the image showing the workflow).

But would like to assign the document to 'varying number' of members.
Can you please let me know if there is a way to do?
Thanks

Hi jllort,
Thanks for the link.
I was able to create a 'TaskNode' dynamically based on the link you had provided.

Have a couple of questions on it:
- How to assign a task to an user? Can I use the 'actorId' in 'setActorIdExpression' using either the 'swinlane' or ''task"
Code: Select all
Swimlane swimlane = new Swimlane();
swimlane.setActorIdExpression("okmAdmin");
OR
Code: Select all
task.setActorIdExpression("okmAdmin");
- How to send a notification mail for the newly created 'TaskNode'?

Thanks in advance,
Vasu

If is not send automatically by WF engine, you could use MailUtils

Hi jllort,
I get the following error when the workflow completes.
Any idea why this error is occurring?

I have attached my project.
The code for 'dynamic task' is in the file 'ActorAssigment.java'.
Thanks in advance,
Vasu

Hi jllort,
I am not saving anything to the database explicitly.
Not sure if the workflow process tried to save something to the database.

Did you get a chance to look into the code to see if I am missing anything?
Thanks in advance,
Vasu

Hi jllort,
Sorry, looks like the project did not get attached because of the size and I had assumed that the project was attached successfully.
Attaching the project now.
Thanks in advance,
Vasu

Which database are you using? Default one does not work very well with workflows and should user another one like MySQL.

Hi pavila,
We are using mySQL database.

In order to assign an actor to a task, use this code:
Code: Select all
public void assign(Assignable assign, ExecutionContext execContext) throws Exception {
	assign.setActorId(validator);
}
To create dynamic tasks use this code:
Code: Select all
public void createDynamicTaskNode(ProcessInstance procInst, String taskName, String actorId, Node originNode, Map<String, Node> toTransitions) {
	log.info("createDynamicTaskNode({}, {}, {}, {})", new Object[] { taskName, actorId, originNode, toTransitions });
	// Add the dynamic task node.
	// - Create the task.
	Task task = new Task(taskName);
	task.setProcessDefinition(procInst.getProcessDefinition());
	procInst.getTaskMgmtInstance().getTaskMgmtDefinition().addTask(task);
	task.setActorIdExpression(actorId);
	
	// - Create the node.
	TaskNode taskNode = new TaskNode("Dynamic task node - " + taskName);
	taskNode.addTask(task); // Adds both ends of the association TaskNode <-> Task.
	procInst.getProcessDefinition().addNode(taskNode); // Adds both ends of the association ProcessDefinition <-> Node.
	Event event = new Event("node-leave");
	Action action = new Action();
	action.setActionExpression("print(\"Saliendo del nodo\");");
	event.addAction(action);
	taskNode.addEvent(event);
	
	// Create transition between originating node and dynamic task node.
	Transition transition = new Transition("from " + originNode.getName());
	originNode.addLeavingTransition(transition);
	taskNode.addArrivingTransition(transition);
	
	// Create transition between dynamic task node and target node.
	for (Entry<String, Node> toTransition : toTransitions.entrySet()) {
		transition = new Transition(toTransition.getKey());
		taskNode.addLeavingTransition(transition);
		toTransition.getValue().addArrivingTransition(transition);
	}
}
