Hi Alex, I tried your code snippet with a minimal sample and I couldn't get it to run... I embedded the code below into the standard qooxdoo stub:
--snip--
var url = "http://www.catify.com/demo/json/dummy.json";;
var jsonStore = new qx.data.store.Json(url);
jsonStore.addListener("loaded", function(e)
{
// model is created at this point
// and the data of the given event ('e' parameter)
// is the created model
this.doSomethingWithTheModel(e.getData());
}, this);
},
doSomethingWithTheModel: function(model){
alert(model);
}
--snip--
The json document is really simple, too:
{
foo: "foo",
bar: "bar"
}
If I call the index page, nothing will happen - no exception reported be
firebug, but no 'alert' window, too. Can you (or anyone else) give me a hint,
where the mistake is?
Thanks in advance - Claus
