You can then use a task listener that starts the desired command asynchronously. When the command finishes, it uses Activiti's api or rest to complete the task.</SPAN></BODY></HTML> Thu, 20 Aug 2015 10:55:26 GMT https://connect.hyland.com/t5/alfresco-archive/error-while-deploying-bpmn-with-service-task/m-p/203187#M156317 pmsevestre 2015-08-20T10:55:26Z
