[Users] Help with OpenLayers.Format.GeoJSON

[Pol]

Thanks Eric, but...

How to include such code in my current application ?

I'm doing these:

MyReader = new OpenLayers.Format.GeoJSON({
read: function() {
          var obj = OpenLayers.Format.JSON.read.apply(this, arguments);
          return OpenLayers.Format.GeoJSON.read.apply(this, obj->#data);
      }
  });

And then ? I don't know how to use it in my store...

Thanks for helping !
