Hi,

I'm attempting to write a simple test application to list the workflow definitions on a SharePoint Online site. I've tried both a provider hosted CSOM and JSOM approach and I cannot get any definitions listed. The CSOM approach is standard code as follows..

public ActionResult About()
        {
            User spUser = null;
            var spContext = SharePointContextProvider.Current.GetSharePointContext(HttpContext);

            using (var clientContext = spContext.CreateUserClientContextForSPHost())
            {
                if (clientContext != null)
                {
                    WorkflowServicesManager wfServicesManager = new WorkflowServicesManager(clientContext, clientContext.Web);
                    WorkflowDeploymentService wfDeploymentService = wfServicesManager.GetWorkflowDeploymentService();
                    WorkflowDefinitionCollection wfDefinitions = wfDeploymentService.EnumerateDefinitions(false);


                    clientContext.Load(wfDefinitions);
                    clientContext.ExecuteQuery();

                    StringBuilder builder = new StringBuilder();

                    foreach (var def in wfDefinitions)
                    {
                        builder.AppendLine("Workflow" + def.DisplayName);
                    }

                    ViewBag.Message = builder.ToString();
                }
            }
            return View();
        }

I've created and deployed both Sharepoint 2010 approval workflows and 2013 list based workflows and a site workflow and non of the definitions show up.

My JSOM and CSOM apps run fine in every other respect but no workflows are listed. Any idea greatly appreciated..

Thanks
