Hi, Most likely it's the label, what's undefined.
OpenLayers use the default style for rendering the vertices and in this context the attribute 'name' isn't defined. Were your color undefined, then the renderer would use black to render the features, but doesn't display a text message. If you want to change this behaviour, then look at the function OpenLayers.Control.ModifyFeature.collectVertices Arnd -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Alex Dean Gesendet: Montag, 30.

Screenshot of feature when I'm not editing it : http://skitch.com/alexdean/dwe1i/without-editing Screenshot of feature while editing: http://skitch.com/alexdean/dwe14/with-editing Using Firebug/Firefox, I can see the following SVG for one vertex. <circle id="OpenLayers.Geometry.Point_146" cx="827.6666666759318" cy="79.09283407817736" r="6" fill="undefined" fill-opacity="0.5" stroke="undefined" stroke-opacity="0.8" stroke-width="4" stroke- linecap="round" stroke-linejoin="round" stroke-dasharray="none"/> I see 'undefined' is the value use for 'fill' and 'stroke', so I imagine one of these may be the problem. I can't figure out what keys I need to define in my style objects to resolve this problem. Can someone help? This is how I've defined the layer: wfs = new OpenLayers.Layer.Vector("Regions", { styleMap: new OpenLayers.StyleMap( { 'default':{ label: "${name}", fillColor: "${color}", fillOpacity: 0.5, strokeColor: "${color}", strokeOpacity: 0.8, strokeWidth: 4, pointRadius: 6, fontColor: "#000000", fontSize: "24px", fontFamily: "Courier New, monospace", fontWeight: "bold" } }) }); The edit control is defined as follows: var edit = new OpenLayers.Control.ModifyFeature(wfs, { title: "Edit Existing Region", displayClass: "olControlModifyFeature" }); As you can see in the screenshots, the 'color' attribute (eg "$ {color}") has been set for the feature in question and is rendered correctly when I'm not editing the feature. The 'undefined' text only appears when I edit the feature using an instance of OpenLayers.Control.ModifyFeature. thanks, alex _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
