What do I need to do besides configuring PTC.BPE.BusinessProcessNotifier?
I am using Thingworx for Manufacturing App. I configured a workflow using Workflow Builder, and added a User Task. I configured PTC.BPE.BusinessProcessNotifier with correct mail server settings, and also PTC.BPE.UserTaskHelper according to help at http://support.ptc.com/cs/help/thingworx_hc/converge_6.5_hc/index.jspx?id=Converge_BPCreate&action=show. Then I duplicated a mashup from PTC.BPE.UserTaskPanel. The problem is I didn't receive any mail notification when workflow stopped at the User Task showing In Progress. I can change the workflow state from thingworx workflow management web page. What could be the reason?
