Hello, I succeded to get it working in firebug, I was using Firefox Beta 4 and Firebug is having some issues with it.
Check this: http://img163.imageshack.us/img163/5491/screenshot20100928at100.png The code related to that screenshot is there: http://gist.github.com/600596 or here: MarkersStore = new GeoExt.data.FeatureStore({ layer: MarkersLayer, proxy: new GeoExt.data.ProtocolProxy({ protocol: new OpenLayers.Protocol.HTTP({ url: marker_api_url, params:{'method':'\"markers.get\"'}, format: new OpenLayers.Format.GeoJSON({ read: function() { console.log("var This: " + this); console.log("var arguments: " + arguments); var obj = OpenLayers.Format.JSON.prototype.read.apply(this, arguments); console.log("var obj: " + obj); return OpenLayers.Format.GeoJSON.prototype.read.apply(this, obj["#data"]); }, 'internalProjection': proj900913, 'externalProjection': proj4326 }), readWithPOST: true }) }), autoLoad: true, }); The var obj is always NULL... can you help me please ?
