    You have to actually load the GeoJSON features into the layer.

    

    First, look at the following examples:

    

    http://openlayers.org/dev/examples/geojson-reprojected.html

    http://openlayers.org/dev/examples/cartodb-geojson.html

    

    They both use a Fixed strategy which is the best one if you want to
    load your data once and have it in a static file or known URL.

    

    You would add your style definition to the vector layer definition
    they present in these examples and then you would have a layer with
    features to be symbolized.

        Hello,

            

            I have some features in GeoJSON format I want to display, so
            I did this:

            

            [code]

                  var vectorLayer = null;

            

                    var vectorStyle =

                    {

                        graphicName: 'square',

                        strokeColor: '#222',

                        fillColor: '#222'

                    };

            

                    var styleDefault = OpenLayers.Util.applyDefaults(

                        vectorStyle,

                        OpenLayers.Feature.Vector.style['default']

                    );

            

                    vectorLayer = new OpenLayers.Layer.Vector('search',

                    {

                        styleMap: new OpenLayers.StyleMap(

                        {

                            'default': styleDefault

                        }

                        ),

                        displayInLayerSwitcher: true

                    }

                    );

          [/code]

            

            but they don't appear in the map, my question is if this is
            enough to get the features displayed or do I need something
            else there? if this is enough, I should think that this
            problem is about how the features are being read by OL. In
            fact, this doesn't work either:

            

            var ll = new OpenLayers.LonLat(feature.geometry.x,
            feature.geometry.y);

            mapPanel.map.setCenter(ll);

            

            I get: 

            

          
          feature is not defined
          
          
            
              
                
                
                    var ll = new OpenLayers.LonLat(feature.geometry.x, feature.geometry.y);
                  
              
            
          
          

            why should this happen? thanks in advance
