Dear Till, Christopher and Alexandre, thank you again. Some steps further but not at the target :-(
@Till: I got your example doing an onmouseover with an OpenLayers.Popup. The internal id is recognised but I don`t get for example the name, gid or other attributes as you did by: "myFeature.data.gid", "myFeature.data.name" etc. An "alert (myFeature.data.gid);" in my case is undefined: ---> http://www.tourismus-maps.de/behncke/openlayers/workshop/test_wfs_1.html?lon_lat=8.05612609964141,52.2713145994324 Is there a special way you declared the "data"-Object? @Alexandre: I got your example to run locally with your WFS, but not yet with mine: http://www.tourismus-maps.de/behncke/openlayers/workshop/test_wfs_2.html?lon_lat=8.05612609964141,52.2713145994324 In your example you did: ----------- wfs = new OpenLayers.Layer.Vector("States (SVG)", { styleMap: styleMap, projection: new OpenLayers.Projection("EPSG:4326"), strategies: [new OpenLayers.Strategy.BBOX()], protocol: new OpenLayers.Protocol.WFS({ version: "1.0.0", url: "http://sigma.openplans.org/geoserver/ows";, featureType: "states", srsName: "EPSG:4326", featureNS: "http://www.openplans.org/topp";, geometryName: "the_geom", schema: "http://sigma.openplans.org/geoserver/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=topp:states"; }) }); ------------ As it`s written here (http://dev.openlayers.org/apidocs/files/OpenLayers/Protocol/WFS/v1-js.html) the URL should be the WFS-Service I think, but so far no succes (neither with: http://www.tourismus-maps.de/cgi-bin/mapserv?map=/home/promotion/behncke/gastronomap_wms/gastronomap_wfs.map&SERVICE=WFS&VERSION=1.0.0&Request=GetFeature&Typename=gastronomie_wfs nor with:http://www.tourismus-maps.de/cgi-bin/mapserv?map=/home/promotion/behncke/gastronomap_wms/gastronomap_wfs.map) I wonder what happens at your: featureNS: "http://www.openplans.org/topp"; ? In the moment I try with: ------------------ wfs = new OpenLayers.Layer.Vector("gastronomy", { styleMap: styleMap, projection: new OpenLayers.Projection("EPSG:900913"), strategies: [new OpenLayers.Strategy.BBOX()], protocol: new OpenLayers.Protocol.WFS({ version: "1.0.0", url: "http://www.tourismus-maps.de/cgi-bin/mapserv?map=/home/promotion/behncke/gastronomap_wms/gastronomap_wfs.map";, featureType: "gastronomie_wfs", srsName: "EPSG:900913", featurePrefix: "feature", geometryName: "the_geom_900913", schema: "http://www.tourismus-maps.de/cgi-bin/mapserv?map=/home/promotion/behncke/gastronomap_wms/gastronomap_wfs.map&service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=gastronomie_wfs"; }) }); ------------- ....but neither the wfs-objects are visualized nor does the popup-window appear. I think it might has something to do with featureNS:?? Might the problem occur because I`m using a WFS by UMN MapServer, it shouldn`t, should it? Has anybody an idea please?
