The initiator-variable is set by alfresco WorklfowService when the process starts. if it's started using a timer, you should add the variable yourself by using, for example, a ExecutionListener on workflow-start. The code responsible for this:


 // Add the initiator
            NodeRef initiator = getPersonNodeRef(currentUserName);
            if (initiator != null)
            {
                variables.put(WorkflowConstants.PROP_INITIATOR, nodeConverter.convertNode(initiator));
                // Also add the initiator home reference, if one exists
                NodeRef initiatorHome = (NodeRef) nodeService.getProperty(initiator, ContentModel.PROP_HOMEFOLDER);
                if (initiatorHome != null)
                {
                    variables.put(WorkflowConstants.PROP_INITIATOR_HOME, nodeConverter.convertNode(initiatorHome));
                }
            }

Thank you Frederik … I was trying to find some reference on how to set the initiator for a couple of days. I'm new to Alfresco, Activiti, Java and Javascript (go figure what I'm doing here), so I'm probably doing something wrong.

Created a ExecutionListener on workflow-start with the code you suggested. Here is my definition:

Don't use org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener, use org.alfresco.repo.workflow.activiti.tasklistener.ScriptExecutionListener.. There is a difference between execution-listeners and task-listeners.

I provided you the JAVA code as it's used by alfresco, you'll have to translate it to JS yourself and apply a similar pattern OR add a ServiceTask, backed by a JavaDelegate with that java-code in it.

Thank you again for pointing me in the right direction. I had just noticed that it's a JAVA code and not JS
I'll do some research and, as soon as I have it figured out, I'll post back here.

Couldn't find a way to do it using WebScript. Do you have a document/guide to get me started?

To do what using a web script?

Set the initiator-variable, using a ExecutionListenter on workflow-start (using JavaScript instead of Java)

No, the execution-listeners run inside the process, so no matter how the process is started (worklfowService API, rest-call, timer-start, ..) this will be called.

I am having the same problem. I am starting workflow instances, or should be, to different users with javascript. Can not get the Initiator attribute to a chosen user. It's always the user who runs the script/JS.

How would I use a javadelegate and a service task?
