I can successfully use a rich:fileUpload component when I go to the url directly: upload.jspx

While in the same session I can use a forward from a RequestDispatcher to access the fileUpload component and everything works fine.

Problem: If I start a new session and use the forward from the RequestDispatcher first I get:

javax.servlet.ServletException: viewId:/upload.jspx - View /upload.jspx could not be restored.

Am I doing something wrong here, or should I enter this as a bug ?
