I am currently testing the Area Tweet tutorial application (you can find the full source code by following the Creating the Area Tweet app link) on Firefox OS and I am encountering the following issue: the application does the call to the Twitter API, but does not receive a response, but the following WARN/ ERROR:
[JavaScript Warning: "CSP WARN:
Directive script-src app://myapp1002.gaiamobile.org violated by
http://search.twitter.com/search.json?callback=twitterCallback&q=test&_=1360318777176"]
What is the issue here? Is this a hint for not receveing a response to the API request or is there something else? I tested the application on both Firefox and Chrome browsers (on Windows) and it works fine.
I might also add that I tested the Firefox OS Boilerplate App and this one seems to work just fine. The only difference I see between these two web applications is that Area Tweet uses jQuery, while the boilerplate one does not. One modification that I did to the original source code of Area Tweet is that I load the jQuery libraries from localhost (to comply with the Mozilla packaging policy), but that does not seem to be the problem.
Add to your manifest.webapp request for network-http permission (this would allow your app to disable same origin policy) and use reqular json request to twitter (without callbackparameter).
