Hi to all the folks,
I need to recover the properties of the user when i re-assigned a task (in the Advanced WorkFolw AdHoc Task), it's possible to get this information?
I have a rule that start a workflow:

var workFlow = actions.create("start-workflow");
workFlow.parameters.workflowName = "jbpm$wf:my_adhoc";
workFlow.parameters["bpm:workflowDescription"] = newFile.name;
workFlow.parameters["bpm:assignee"] = person;
workFlow.parameters["wf:notifyMe"] = false;
workFlow.execute(newFile);

So, imaging the person who kicked off the rule is an administrator the bpm_assigne is, during the workflow, valued with the administrator properties.
But if the administrator decide to re-assign this task to another user and i want to send an e-mail to this user, for example,  for warning it that there is a task it must develop, how can do it?
Have had someone the some problem and able to give me an hint?
Thank you very much,
Best regards
Alessio A.

Hi Alessio,

This is an interesting feature, so I played around with adhoc_processdefinition.xml and came up with the following addition:

   
  <task name="wf:adhocTask" swimlane="assignee">
       …
     <event type="task-assign">
             <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
                <script>
                   if (taskInstance.previousActorId != null &amp;&amp; (taskInstance.previousActorId != taskInstance.actorId))
                   {
                      // retrieve person objects identified by task actorId and previousActorId
                      // TODO: provide built-in task properties that do the following search for you
                      var previousActor = search.luceneSearch("@cm\\:userName:\"" + taskInstance.previousActorId + "\"");
                      var actor = search.luceneSearch("@cm\\:userName:\"" + taskInstance.actorId + "\"");
                      
                      // send e-mail
                      var mail = actions.create("mail");
                      mail.parameters.to = actor.properties["cm:email"];
                      mail.parameters.subject = "Re-assigned Adhoc Task " + bpm_workflowDescription;
                      mail.parameters.from = previousActor.properties["cm:email"];
                      mail.parameters.text = "Hey, I've assigned you my task. Regards " + previousActor.properties["cm:firstName"];
                      mail.execute(bpm_package);
                   }
                </script>
             </action>
          </event>
          
         ….
     </task>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm using a task event called 'task-assign' which is fired whenever the task  is first assigned to someone and when it's re-assigned to someone else.

Within this event, the variable called 'taskInstance' (a standard jBPM variable) is available.  This has attributes actorId and previousActorId.   I've used these to locate the respective Alfresco person objects.

Then I just send an e-mail in the usual way.

I will file an enhancement request to add variables for accessing the current task owner and previous task owner (as Alfresco person objects) without resorting to searching manually.
