Assign a task to a group

bgl — Tue, 31 Jul 2007 14:57:10 GMT

Hi,I would like to assign a task to a group of persons. Task could then be handled by one of the group.But it does not seem possible in the user interface of Alfresco. Did I miss something ?I know this is possible in jBPM since it is written in their documentation :wink: . Is this feature supported

If you're referring to jBPM Pooled tasks, then they are exposed in Alfresco. There are further workflow definitions in

workflow-context.xml.sample‍

residing in

config/alfresco/extension‍

One of the definitions demonstrates pooled tasks - review_pooled_processdefinition.xml.

Just take off the .sample extension and re-start the server.

You'll also need to add the 'My Pooled Tasks' dashlet to the dashboard.

Hi David,

Thanks a lot for your answer. That's almost what I was looking for.

I see new now those features in advanced workflow:
Parallel Review & Approve (Parallel Review & approval of content)
Group Review & Approve (Group review & approval of content)
Review & Approve (Review & approval of content)
Pooled Review & Approve (Pooled review & approval of content)
Adhoc Task (Assign task to colleague)

So there is no way, out of the box, to assign a task to a group or a pool of actors if I understand well. If I want this I have to write it. Is that right ?

I've played around with group and pool feature. They are great but I saw a problem. I post a new thread about it since it is a new topic.

Perhaps you could clarify your requirement here. Do you mean you'd like to assign an ad-hoc task a group or pool?

Re: Assign a task to a group

bgl — Wed, 01 Aug 2007 12:15:45 GMT

Yes it is exactly this.

I would like to delegate some tasks to persons that are part of a group. So I wanted to use ad-hoc tasks to do this.

Do you see another way to do this ?

Thanks

Boris

If that's the process you require, then that's the process. Alfresco allows you to define your own processes, so I took the out-of-the-box adhoc process and converted it to a pooled adhoc process.

Create the following files in your config/alfresco/extension directory:

Well, you can help me? I am trying to create a workflow or modify one that already exists, so that once established, can reassign the task to multiple users or multiple groups, by default only allows Alfresco to reassign a user.

Thanks and regards

Hi,

Can someone explain what this part of the processdefinition does and why it is needed?

                   <variable name="bpm_assignee" access="write"/>
                   <expression>
                      if (taskInstance.actorId == undefined)
                         person;
                      else
                         people.getPerson(taskInstance.actorId);
                   </expression>
‍‍‍‍‍‍‍‍

Much appreciate.

Thanks

This part'task is that:
If taskInstance has not any valid(defined) actor, then actor(assignee) becomes the current user, otherwise defined actor becomes assignee.

I saw the error when I choose to assign to a group. If you see my previous post(http://forums.alfresco.com/en/viewtopic.php?f=34&t=27866) the same thing happened for the Group user

Pls Help.

Thanks in advance

David, this is very helpful. However I have a further question: how do I make it so that I have two distinct types of assignees: copyeditors and authors?
