AW: [OpenLayers-Users] Call a SLD file for a Vector Layer

[gbrun]

Thanks for your reply!

So I tried to so something with the LoadURL. The SLD file is well called  
(I can see it in firebug), but the problem is that I now don't know how to  
link it with its layer. I'm still a newbie in webmapping. I think, what I  
want to do is quite easy, but I'm still not used to! Here is my current  
code:

		createWFSLayer: function(data, featureType) {
			
			//Style definition			
			var sld;
			var layername = featureType.name;
			var url_sld = "sld/"+layername+".xml";
			
			var format_sld = new OpenLayers.Format.SLD();
			
			OpenLayers.loadURL(url_sld, null, null, complete)
			
			function getDefaultStyle(sld, layerName) {
				var styles = sld.namedLayers[layerName].userStyles;
				var style;
				for(var i=0; i<styles.length; ++i) {
					style = styles[i];
					if(style.isDefault) {
						break;
					}
				}
				return style;
			};
			
			function complete(req) {
				sld = format_sld.read(req.responseXML || req.responseText);
				
				var styleMap = new OpenLayers.StyleMap({
						"default": getDefaultStyle(sld, layername)
				});
				return styleMap;
			}
			
			var styleWFS = {styleMap: styleMap}
			
			//Layer options
			var layerOptions, protocolOptions;
			//Layer options definition
			protocolOptions = {
				url: data.capability.request.getfeature.href.post,
				featureType: featureType.name,
				featureNS: featureType.featureNS,
				outputFormat: "json",
				readFormat: new OpenLayers.Format.GeoJSON()
			};
			//Layer protocol definition
			layerOptions = {
				protocol: new OpenLayers.Protocol.WFS(protocolOptions),
				strategies: [new OpenLayers.Strategy.Fixed()]
			};
			return  new OpenLayers.Layer.Vector(
				featureType.title,
				layerOptions,
				styleWFS
			);
		},

My problem comes from the "complete" function. I can't get its result for  
the styleMap property of my layer!
