[OpenLayers-Users] ModifyFeatrure Control and vertexRenderIntent

[Robert Sanson]

I have a polygon vector layer which I have a ModifyFeature control set against. The default StyleMap for the layer has a label based on a name property. Unfortunately, I have not been able to turn off the labels for the vertices when a feature is selected for modification.

Here is my style map:

var crop_style = new OpenLayers.StyleMap({
    "default": new OpenLayers.Style(
        {
            pointRadius: 3,
            strokeColor: "#ff6103",
            fillColor: "#ffcc99",
            fillOpacity: 0.4,
            strokeWidth: 2,
            label: "${name}",
            fontColor: "blue",
            fontSize: 10,
            fontFamily: "Arial",
            fontWeight: "bold"
        }),
    "temporary": new OpenLayers.Style(
        {
            pointRadius: 3,
            strokeColor: "#ff6103",
            fillColor: "#ffcc99",
            fillOpacity: 0.4,
            strokeWidth: 2,
	    label: null
        }),
	"select": new OpenLayers.Style(
        {
            pointRadius: 3,
            strokeColor: "#ff6103",
            fillColor: "#0000ff",
            fillOpacity: 0.4,
            strokeWidth: 2,
	    label: null,
	    fontColor: null,
            fontSize: null,
            fontFamily: null,
            fontWeight: null
        }),
	"vertex": new OpenLayers.Style(
        {
            pointRadius: 4,
            strokeColor: "#ff6103",
            fillColor: "#ff0000",
            fillOpacity: 0.4,
            strokeWidth: 2,
	    label: null,
	    fontColor: null,
            fontSize: null,
            fontFamily: null,
            fontWeight: null
        })
  }, {extendDefault: false}
  );

Here are the controls that are specified against the layer:

var fpControls = {
                dpoint: new OpenLayers.Control.DrawFeature(fpts,OpenLayers.Handler.Point),
                modify: new OpenLayers.Control.ModifyFeature(fpts, {vertexRenderIntent: "vertex"}),
                delf: new OpenLayers.Control.SelectFeature(fpts, {onSelect: function(feature) {feature.attributes.pstate = "del";
                                                                                                 feature.style = style_fptsdel;
                                                                                                 fpts.drawFeature(feature);
                                                                                                 }
											}
									)
      };

I don't seem to get the "vertex" renderintent working. The vertices and pseudovertices all have a label "undefined", which stops me being able to drag them or delete them.

Any help appreciated.

Thanks,

Robert Sanson
