var format = new OpenLayers.Format.GeoJSON();
var features = format.read(foo);
vectorLayer.addFeatures(features);
Have you considered using a callback function? If your response looks
like "callback(...)" your JS code will be
function callback(geojson) {
var format = new OpenLayers.Format.GeoJSON();
var features = format.read(geojson);
vectorLayer.addFeatures(features);
}
