Ajouter des features dans un vector layer

[Nico]

Bonjour,

je voudrais afficher un vector layer que j'alimente "à la main" avec des features

var defaultStyle = new OpenLayers.Style({
                'pointRadius': 3,
                'strokeWidth': 2,
                'strokeColor': '#0000ff',
                'fillColor': '#ffff00'
});

var selectStyle = new OpenLayers.Style({
                'pointRadius': 3,
                'strokeWidth': 2,
                'strokeColor': '#ff0000',
                'fillColor': '#ffff00'
});

var style = new OpenLayers.StyleMap({
            'default': defaultStyle,
                           'select': selectStyle
});

var select = new OpenLayers.Layer.Vector("vector", {
            projection: new OpenLayers.Projection("EPSG:4326"), 
            styleMap: style
});

var mapOptions = {projection: new OpenLayers.Projection("EPSG:4326"),
        displayProjection: new OpenLayers.Projection("EPSG:4326"),
        maxExtent: new OpenLayers.Bounds(-5.0, 45.0, 0.0, 50.0)
};
var map = new OpenLayers.Map('map', mapOptions);

var wmsLayer = new OpenLayers.Layer.WMS(
                "vmap0",
                "http://vmap0.tiles.osgeo.org/wms/vmap0",
                {layers: 'basic', isBaseLayer:true}
);

var tch = new OpenLayers.Layer.WMS(
                "TCH",
                "http://monsite.fr:8080/geoserver/wms",
                {layers: 'monlayer', transparent: true}
);

var lonLat = new OpenLayers.LonLat(-4.5,48);
select.addFeatures([new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(lonLat))]);

map.addLayers([wmsLayer, tch, select]);

les 2 layers wmsLayer et tch s'affichent bien, mais le layer select ne s'affiche pas.

Qu'est ce qui cloche ?

Merci,
Nico
