For me the problem here was that the code for the `<.simple_form` appeared too early (page 136 and 137 in PDF B10.0 ). It is explained, and re-appears later on page 139.  
Without `<simple_form` the live view worked, and seeing the page gave me a sense of progress. Adding the form on page 139, once the wiring was there, was smooth.
