If you use the Alfresco WorkflowService or workflow action, you would not need to initiate the initiator variable yourself as this is already done by the service.</SPAN><BR /><BR /><SPAN>Regards</SPAN><BR /><SPAN>Axel</SPAN></BODY></HTML> Tue, 11 Sep 2012 23:13:24 GMT https://connect.hyland.com/t5/alfresco-archive/assign-a-workflow-s-task-user-initiator-from-java/m-p/259489#M212619 afaust 2012-09-11T23:13:24Z
