Is this service still valid for Twitter, since they changed the usage of their service. I guess you have to use the OAuth mechanism to get data from Twitter.

Do you already tried the URL with your browser to be sure that valid JSON is returned? > my file system variant: > var url = "/var/www/demo/processes/testprocess_01.json"; > this.__store = new qx.data.store.Json(url); > > result --> __store is "undefined", model is > "null" (qx.io.remote.transport.XmlHttp[51]: Could not load from > file: /var/www/demo/processes/testprocess_01.json) This is a issue with SOP (Same Origin Policy). The browser does not allow to read URLs which are not located in the same directory. > I'm using qooxdoo 1.2 and we're here behind a proxy server (perhaps this > is relevant). Maybe, the best idea I have to check the URLs in your browser first to validate that the result is correct. > By the way if I try to generate the model directly from JSON I'm getting > the model without problems: > > var model = qx.data.marshal.Json.createModel({ > processName: "TESTPROCESS", > processVersion: "1.2", > processDescription: > ... It seems that the URLs you provide do not return the right result. cheers, Alex ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ qooxdoo-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/qooxdoo-devel
