Thanks Mike and Chuck. I did forget to enter values for the external types. I had been through the steps to set up the EOModel so many times trying to get it to work that I eventually convinced myself that the docs were wrong and those values weren't used for anything. Eventually I just started overlooking them in the setup. It would help to have warnings for required fields. Thanks for getting me unstuck.
