[OpenLayers-Users] BBOX Strategy and StyleMap problem

[Mario Danelli]

Dear all,

I've a problem trying to apply a custom (different marker pngs following 
a specific type) markers when using BBOX Strategy to get features data. 
I'm using Openlayers 2.12.

Below the code


var pois = new OpenLayers.Layer.Vector("POIs", {
			        projection: new OpenLayers.Projection("EPSG:4326"),
					strategies: [new OpenLayers.Strategy.BBOX({resFactor: 1.1})],
			     	protocol: new OpenLayers.Protocol.HTTP({
						url: "./get_data.php",
			            format: new OpenLayers.Format.Text()
			        }),
			        styleMap: new OpenLayers.StyleMap({
								"default": {
									externalGraphic: "./js/openlayers/img/marker-${type}.png",
									graphicHeight: 20,
									name: "${id}",
									id: "${type}" + "-" + "${id}"
							}
					})

map.addLayer(pois);
pois.setVisibility(true);
				
pois.events.on({
	    'featureselected': onFeatureSelect,
	    'featureunselected': onFeatureUnselect
	});

selectControl = new OpenLayers.Control.SelectFeature(pois);

map.addControl(selectControl);
selectControl.activate();


the "get_data.php" returns data as example below

id	point	ref_lat	ref_lon	name	descr	type
2	55.92,14.3	55.92	14.3	Name1	descr1	t1
3	56.1,10.2	56.16	10.2	Name2	descr2	t2
4	56.13,10.21	56.13	10.21	Name3	descr3	t1


The goal is to have different markers (colours) if the points are of 
type "t1" or "t2". But it's nevere selected the correct marker (for 
example: marker-t1.png) but every time is selected the default marker.png.
The behaviour is the same if I specificy a "not parameterized" marker 
(for example externalGraphic: "./js/openlayers/img/marker-ABC.png").

What's wrong?

Anyone can help me?

Thanks
