Since I posted this question, this issue has resolved itself. There must have been a glitch on Facebook or my dev server. Anyway, thanks to those of you who tried to help.<\/p>\n
I have a Facebook app that runs on two servers: a live server and a dev server.<\/p>\n
I was making some changes on dev and testing them when FBJS failed with an error (undefined functions)<\/p>\n
I continuously reverted my changes to the dev server but could not get it working. So I reverted to the same revision that works on my live server, but it still fails on the dev server.<\/p>\n
The source of the error appears to be a single JS file. I have verified in every way possible that this is the exact same file I am using on the live server where it works, but it is failing on the dev server with “undefined functions”.<\/p>\n
I am at my wits end with trying to debug this. I could really use some helpful suggestions. Thanks in advance for any help you can offer.<\/p>\n
If you’re interested in reviewing the apps, you can find there here:<\/p>\n
Live: http:\/\/apps.facebook.com\/rails_across_europe<\/p>\n
Dev: http:\/\/apps.facebook.com\/rails_dev<\/p>\n
Note that you must give the app permission to access your FB profile data.<\/p>\n
Facebook caches external JS and CSS on FBML pages. Add a cache breaker to the JS URL:<\/p>\n
http:\/\/example.com\/js.js?version=1\n<\/code><\/pre>\nwhat I do to automatically keep in sync is, during development, I append the current timestamp as a version number. Then, when I go live, I increment the live URL by 1. I’ve automated this as well, and I suggest you do the same.<\/p>\n<\/li>\n<\/ol>\n
