Combobox not loading json response

[crowolf]

Hello,
I'm having some trouble with the ComboBox. My response from the server is valid and looks okay when going to the url with a browser. The ComboBox is stuck on 'Loading...' however.

This is the code of the view:

String url = "/SDIQueryServlet?ns=[%22NCBI Taxonomy%22]";
    ScriptTagProxy<PagingLoadResult<ModelData>> proxy = new ScriptTagProxy<PagingLoadResult<ModelData>>(url);

    ModelType type = new ModelType();
    type.setRoot("terms");
    type.addField("term", "term");

    JsonPagingLoadResultReader<PagingLoadResult<ModelData>> reader = new JsonPagingLoadResultReader<PagingLoadResult<ModelData>>(type);

    PagingLoader<PagingLoadResult<ModelData>> loader = new BasePagingLoader<PagingLoadResult<ModelData>>(proxy, reader);

    loader.addListener(Loader.BeforeLoad, new Listener<LoadEvent>() {
        public void handleEvent(LoadEvent be) {
        be.<ModelData> getConfig().set("start", be.<ModelData> getConfig().get("offset"));
        }
    });

    ListStore<ModelData> store = new ListStore<ModelData>(loader);

I query a servlet that lives on my own server and use that as a proxy to a remote server.
The response I get in my servlet is fine:

{"terms":[{"term":"content", "term2":"content2"}]}

Am I missing something here?
I tried adding a listener to the loader for the Loader.Load event, but that never triggers.
Any help would be most welcome!

Your response is not fine for a ScriptTagProxy. Your server gets a callback param which you need to use. Take a look at this example and the response from the server: http://www.sencha.com/examples/explo...vancedcombobox

sven, thanks a bunch for your response!
I went with a HttpProxy instead and that works like a charm =)
