Assign a task to a group

bgl

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

. Is this feature supported by Alfresco ? or do I need to code something ?

Thank you

Boris

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?

bgl

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:

Thanks a lot !

This is really great. I try them and post back about it.

bgl

One word: perfect !

Thanks a lot David !

giorgio

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

giorgio

Much appreciate.

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?
