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 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 · ‎08-01-2007

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:

1) adhocgroup_processdefinition.xml

<?xml version="1.0" encoding="UTF-8"?>

<process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="wfag:adhocgroup">

   <swimlane name="initiator"/>

   <start-state name="start">
      <task name="wfag:submitAdhocGroupTask" swimlane="initiator"/>
      <transition name="" to="adhoc"/>
   </start-state>

   <swimlane name="assignee">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
        <pooledactors>#{bpm_groupAssignee}</pooledactors>
      </assignment>
   </swimlane>
   
   <task-node name="adhoc">
      <task name="wf:adhocTask" swimlane="assignee">
         <event type="task-create">
            <script>
               if (bpm_workflowDueDate != void) taskInstance.dueDate = bpm_workflowDueDate;
               if (bpm_workflowPriority != void) taskInstance.priority = bpm_workflowPriority;
            </script>
         </event>
          <event type="task-end">
             <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
                <script>
                   <variable name="bpm_assignee" access="write"/>
                   <expression>
                      if (taskInstance.actorId == undefined)
                         person;
                      else
                         people.getPerson(taskInstance.actorId);
                   </expression>
                </script>
             </action>
          </event>
      </task>
      <transition name="" to="completed">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
           <script>
              if (wfag_notifyMe)
              {
                 var mail = actions.create("mail");
                 mail.parameters.to = initiator.properties.email;
                 mail.parameters.subject = "Adhoc Task " + bpm_workflowDescription;
                 mail.parameters.from = bpm_assignee.properties.email;
                 mail.parameters.text = "It's done";
                 mail.execute(bpm_package);

Thanks a lot !

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

bgl · ‎08-01-2007

One word: perfect !

Thanks a lot David !

giorgio · ‎05-04-2009

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
