Hi Martin, I got the problem, but I've no solution yet (okay - a possible workaround, but not really a solution ;)
the playground stuff works with the file you provided, because they are on the same server. If I deploy my code on a server and will call a json file (it doesn't matter, if it's your's or mine) that is lying on the same machine it works as well. I found in Nabble [1] something like ...setCrossDomain(true); Can I configure this anywhere? Or an other question - the twitter sample you provided on the qooxdoo page works locally and I'm sending definitely a request to an external server. The difference is qx.data.store.Json and qx.data.store.Jsonp (is that so?). I'm using qx.data.store.Json because I didn't get 100% what is qx.data.store.Jsonp good for and what I have to do on server side... If qx.data.store.Jsonp is the solution I have to go deeper in it. Is this the solution?
