Hi Arnd, thanks for your answer! Please read below.
________________________________ Hi, i'm not sure, why you need a layer for your selected feature. Why not use the selectFeatureControl on the wfs layer. I use my Control.SelectFeature with my wfs layer(wfs2)- or don`t I use the event right? (event.register instead of events.on). I get along with this example: http://dev.openlayers.org/releases/OpenLayers-2.9/examples/getfeature-wfs.html to get back a visual selecting for the user and get back some information about the selected feature. About your question. The problem is the feature object. You add not a new feature to a new layer. Instead it seems, that you move the selected feature from the wfs layer to the new layer. That means wfs.event.on("unselected") cann't work, because your selectFeatureControl works only for the wfs layer. Yes I thought something like that, but could not manage to solve this. Thanks for your example! Use a clone of the feature and remove the only feature on your select layer. layerWFS.events.on({'featureselected': function(feature){ selectLayer.addFeatures([feature.feature.clone()]); //selectLayer.addFeatures([feature.feature]); alert(this.selectedFeatures.length); }, 'featureunselected': function(feature){ selectLayer.removeFeatures([selectLayer.features[0]]); //selectLayer.removeFeatures([feature.feature]); alert(this.selectedFeatures.length + " - unselected"); }, }); A bit confusing is also the style you add as default style to the select layer. It looks like you select a feature on the wfs layer, but it's really the not selected feature on the select layer. So I have to register a select style to my wfs layer and cancel select layer, am I right? best regards Sarah Arnd ________________________________ Von: [email protected] [mailto:[email protected]] Im Auftrag von Sarah Schuessler Gesendet: Montag, 26.

Here is my code: var selectFeature = new OpenLayers.Control.SelectFeature(wfs2, {clickout: true, multiple: false, hover: false, toggle:false, toggleKey: "shiftKey", box: true, multipleKey: "ctrlKey"}); var wfs2 = new OpenLayers.Layer.Vector("WFS_Waldschutz", { styleMap: styleMap, strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.WFS({ url: "http://myserver:81/geoserver/wfs?service=wfs";, featureNS: "http://mycomp.org";, featureType: "mylayer", geometryName: "SHAPE", srsName: "EPSG:4326", version: "1.1.0" }), projection: new OpenLayers.Projection("EPSG:4326") }); wfs2.events.on({'featureselected': function(feature){ select.addFeatures([feature.feature]); alert(this.selectedFeatures.length); }, 'featureunselected': function(feature){ select.removeFeatures([feature.feature]); alert(this.selectedFeatures.length); alert("unselected"); }, }); var select = new OpenLayers.Layer.Vector("Selection", { styleMap: new OpenLayers.Style(OpenLayers.Feature.Vector.style["select"]), displayInLayerSwitcher: true, visibility: true}); featureselected works (at firebug I can see that my app does not get to this break point). What`s wrong? Thank you for any hints. best regards Sarah
