I have upgraded to 1.6.4 with AppEngine and GWT 7.0. I need to develop a Google AppEngine application, so I have to create the new project structure with GWT Plug new wizard for the GWT plugin to recognize it for AppEngine deployment. Design seems to work fine with it, until I was creating a remote service with Design. The wizard creates only the Service interface and the server impl class, but not the Async interface.
Thanks for your help.
