Setting
setRecordXPath("/");
instead of
setRecordXPath("//");
solves the problem.

To be sure to not missing the obvious, could somebody come up with a simple example (at best, using a public server) that uses JSON as a message format and a json-callback?

Confusion with web server binding
Hi,
It is probably only a tiny setting but I am banging my head around it for a while.
I am trying to set up a client side datasource to query a geolocation server.
Documentation on how to query it can be found here: http://open.mapquestapi.com/nominatim/
Since I thought it would be the most efficient to use JSON, I extended the XJSONDataSource and set
Code:setDataFormat(DSDataFormat.JSON); //just to be sure DSRequest dsr = new DSRequest(); dsr.setCallbackParam("json_callback"); //the server expects the callback method parameter to be like this setRequestProperties(dsr); setRecordXPath("//"); //setting it seems to make no difference setDataURL("http://open.mapquestapi.com/nominatim/v1/search"); //Field definitions DataSourceField osm_id = new DataSourceTextField("osm_id"); osm_id.setPrimaryKey(true); osm_id.setHidden(true); // AutoIncrement on server. osm_id.setRequired(true); addField(osm_id); DataSourceField boundingbox = new DataSourceTextField("boundingbox"); boundingbox.setMultiple(true); addField(boundingbox); //a nested field DataSourceTextField clazz = new DataSourceTextField("class"); clazz.setValueXPath("address"); addField(clazz); DataSourceField licence = new DataSourceTextField("licence"); addField(licence); ...
Code:http://open.mapquestapi.com/nominatim/v1/search?q=Manassas&format=json&json_callback=isc.Comm._scriptIncludeReply_1

What am I missing here?
Thanks
