After a day of combing the web, I couldn't figure out why goog was "undefined" in my javascript on a particular client. Turns out my customer's firewall blocks Google's talkgadget.google.com which is where /_ah/channel/jsapi goes to. I use just about every other component of appengine and haven't found any other problems through this firewall.
To solve the problem, I have to check if(goog == undefined) then use an alternative to Channel. If anyone else has a better solution, I'm all ears. Otherwise, sounds like a production ready app will need to be prepared for firewall gotcha's when using Channel. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
