I've been working through Lenz's "Simply Rails 2" book successfully up to Chapter 6 p. 171. All steps have worked for me up until there, but then when going on to the next steps to have the flash notice read 'Story submission succeeded', when I check the application in a browser and submit a story, no such message displays; only the same "stories" page as before.
I'm following the modifications to the files on p. 172-174 exactly and have tried both typing the changes carefully and using the downloaded code. It didn't look like there was any listed errata about this. I've actually even restarted all the steps fresh from the beginning of the book to see if I missed anything and ended up with the same result.
