[Users] Help with OpenLayers.Format.GeoJSON

[Pol]

I also tried this:

MarkersStore = new GeoExt.data.FeatureStore({
layer: MarkersLayer,
proxy: new GeoExt.data.ProtocolProxy({
protocol: new OpenLayers.Protocol.HTTP({
url: marker_api_url,
format: new OpenLayers.Format.GeoJSON({
read: function() {
                        var obj = OpenLayers.Format.JSON.read.apply(this,
arguments);
console.log(obj);
   return OpenLayers.Format.GeoJSON.read.apply(this, [obj]);
                },
'internalProjection': proj900913,
'externalProjection': proj4326
}),
readWithPOST: true
})
}),
autoLoad: false,
});

But it doesn't works. I never get anything in the log.

Can you show me an example ?

Thanks
