Okay, this is most certainly a bug, but it is not a trivial one. The underlying problem is that to render a view component, you have to use the engine context, because you need access to the IViewComponentFactory. This is not passed to the view engine during construction of the view for the mail message. In particular, we have this two overloads:
///<summary> /// Processes the view - using the templateName /// to obtain the correct template /// and writes the results to the System.TextWriter. /// </summary> void Process(string templateName, TextWriter output, IEngineContext context, IController controller, IControllerContext controllerContext); /// <summary> /// Processes the view - using the templateName /// to obtain the correct template /// and writes the results to the System.TextWriter. /// </summary> void Process(string templateName, string layoutName, TextWriter output, IDictionary<string,object> parameters); The first is used for normal views, the second for mail messages. Since the second one doesn't have a context, the view can't figure out the view component factory and fails. Now, for the actual resolution. It would require the email template server to know about the engine context, and I am not sure if this is something that is desirable. thoughts?
