[OpenLayers-Users] delete feature & vertices - further

[Robert Sanson]

I have tried destroyFeatures, removeFeatures and eraseFeatures and they all seem to have the same behaviour. The polygon disappears but the vertices remain.
 
var delf =  new OpenLayers.Control.SelectFeature(crops, {onSelect: function(feature) {crops.destroyFeatures([feature])}});
map.addControl(delf);
delf.activate();

I just tried the following and confirmed that the above works.

1) open http://openlayers.org/dev/examples/draw-feature.html 
2) draw a polygon (note freehand is true here)
3) in the firebug console, run this code:

var del = new OpenLayers.Control.SelectFeature(
     map.layers[3], {
         onSelect: function(feature) {
             map.layers[3].removeFeatures([feature]);
         }
     }
);
map.addControl(del);
del.activate();

4) click on your polygon to see it removed

I suspect you really want to be calling destroyFeatures instead of 
removeFeatures - unless you call feature.destroy elsewhere.
