Assign Task - 2 users

[send2shriram]

Hi,

I want a task to be created to two users. I am unable to find any
JBPM API's for this. Any help would be useful.

Thanks

keyword: PooledActor

Hi ,

Using PooledActor also doesn;t seems to solve the problem as
it first assigns to a pool of actors ,and then only one user (from the pool) can reassign the task.

Any workaround/information/suggestion/help from the JBPM authors and others would be helpful.


Thanks

Hi, send2shiraram!
If pooledActor doesn't work then why don't you create two tasks - one for each user?

Hi Saviola,

Thanks for your reply.

I want one task to be created, and both the users must be assigned to it.
So that, any of the two can take on the task and act upon it.

I tried with PooledActor, as follows; Please correct me if iam wrong.

assignable.setPooledActor("User1","User2","User3")
It initially set the task's ActorID to null but the JBPM_POOLEDACTOR table has reference to the 3 users assigned above.

From here, i can do reAssign the task to either of the User1,User2,User3.
by assignable.setActorId("User1");
will update the task's ActorID to User1.

This doesn;t solve my problem of assigning two users to same task.
Is there a way in PooledActor where we can assign to two users a same task. Is my understanding of PooledActor is correct ?


Thanks Again !!!!

Hi, again Shiraram!
Here what the jBPM documentation says about the sense of pooled actors:

To assign a TaskInstance to a pool of candidate actors, call Assignable.setPooledActors(String[] actorIds).

According to what i've seen in the forum about this concept pooled actors are the

"future possible"

actors who would have been performing particular task or assigned to a particular swimlane instance.(Was that clear enough :( ?) When it comes to the moment when the actual actor is clear it is set through

setActorId(String actorId)

method.
I think that it is rather not possible to actually assign one task to more than one actor simultaneously.
What do you think, jBPM team members?

Shiram,

You want:

I want one task to be created, and both the users must be assigned to it.
So that, any of the two can take on the task and act upon it.

You say pooled actors does:

Using PooledActor also doesn;t seems to solve the problem as
it first assigns to a pool of actors ,and then only one user (from the pool) can reassign the task.

reassign here meaning to himself, so acting upon it.

I do not realy see the difference between what you want and what pooled actors does.

If I miss something, please clarify.

Hi ronald,

Thanks for the reply.

ok... i will refrain my question as follows;

I want a task to be assigned to two actors.

Q1. how can i implement this?
Q2. you would have seen my implementation of PooledActors in
the previous mails. Was that correct ?
Q3. Please clarify PooledActors concept if my previos mail understanding
about it was wrong?
Q4. will PooledActors will be able to solve the problem, if so
could u please explain it?

Thanks in Adv

hi Shriram and others,
I've been trying to do the same thing: to assign the same task instance to more than one user, and up to now i do not succeed either.

What I did:
1- created a group 'g1' whose members are 'user1' and 'user2'.
2- I put in the task definition the element


In this way it should assign the task instances to the pooledactors defined by the statement below, but it does not work.

I also tried to put the same statement in the swimlane element of process definition.

if anyone get this done, let us to know.

thanks
Luciano

Look at the org.jbpm.taskmgmt.TaskAssignmentTest.java. Lots of examples there

There was not a full implementation in the post, just some lines. From that I cannot see if it is good or wrong.

See the test code above.

If I want to assign a task for only 2 people, do I have to create a group for them? Do I need to create an Assignment class for this??

Isn't there an easier way like:

<swimlane name="Swimlane1">
 <assignment expression="user(John)"></assignment>
 <assignment expression="user(Mary)"></assignment>
</swimlane>

or

<swimlane name="Swimlane1">
 <assignment expression=pooledActors("John","Mary")></assignment>
</swimlane>

Using something like this, would become easier to create an GUI to edit task assignments.

[jainer]

<swimlane name="revisor">
 <assignment class="com.factura.handler.Asigna"></assignment>
 </swimlane>

 <task-node name="proyecto">
 <task name="revision proyecto" swimlane="revisor">...

package com.factura.handler;


import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.taskmgmt.def.AssignmentHandler;
import org.jbpm.taskmgmt.exe.Assignable;

public class Asigna implements AssignmentHandler{

 final static long serialVersionUID = 1L;

 public void assign(Assignable assignable, ExecutionContext executionContext){
 assignable.setPooledActors(new String[]{"faber aristizabal", "luis mantilla"});
 }
}

I'M SURE THAT IT WORKS!!!!!!!
