We are using Tridion 2013 and publishing content to the Tridion Broker, and using an Angular Web Application for the website. XPM is implemented and working good for field editing, and also the Finish Editing commits the changes to the backend CMS. However, the Session Preview functionality is not working.
I've read this post discussing some points about XPM and Session Preview, and as I understand it, it involves the CD layer in the Web Application.
The Architecture is DD4T -> Restful Service -> NodeJS -> Angular.
Any ideas if this is possible without the CD / ADF in our web application?
