<div dir="ltr">Hi,<br><br>Thank you for your message. Yes it works, but...<br><br>I have discovered that this problem is in relation with the modify control I use within the same application. If I rem line for declaring modify control the delete function behaves OK. If I include it, then after delete the vertexes remain. If more than one polygon on map then the vertexes disappear from previous deleted polygon and appear where the last deleted polygon resided.... and so on. On some clicks succession a polygon may be redrawn (with lines and fill style), but no delete or drag or edit may be performed. <br>
<br> var modifyOptions = {<br> onModificationStart: function(feature) {<br> OpenLayers.Console.log("start modifying", <a href="http://feature.id">feature.id</a>);<br> },<br>
onModification: function(feature) {<br> OpenLayers.Console.log("modified", <a href="http://feature.id">feature.id</a>);<br> },<br> onModificationEnd: function(feature) {<br>
OpenLayers.Console.log("end modifying", <a href="http://feature.id">feature.id</a>);<br> },<br> onDelete: function(feature) {<br> OpenLayers.Console.log("delete", <a href="http://feature.id">feature.id</a>);<br>
}<br> };<br><br> controls = {<br> ...<br> modify: new OpenLayers.Control.ModifyFeature(vectors, modifyOptions), <br> deletefeature: new OpenLayers.Control.SelectFeature(vectors, {onSelect:deleteFeature}),<br>
...<br> }; <br><br><br>function deleteFeature(feature) <br>{<br> this.layer.destroyFeatures([feature]);<br> //this.layer.removeFeatures(feature);<br>} <br><br>Any hints how to make delete and modify "cooperate"?<br>

</div>I just tried the following and confirmed that the above works.<br>
<br>
1) open <a href="http://openlayers.org/dev/examples/draw-feature.html" target="_blank">http://openlayers.org/dev/examples/draw-feature.html</a><br>
2) draw a polygon (note freehand is true here)<br>
3) in the firebug console, run this code:<br>
<br>
var del = new OpenLayers.Control.SelectFeature(<br>
map.layers[3], {<br>
onSelect: function(feature) {<br>
map.layers[3].removeFeatures([feature]);<br>
}<br>
}<br>
);<br>
map.addControl(del);<br>
del.activate();<br>
<br>
4) click on your polygon to see it removed<br>
<br>
I suspect you really want to be calling destroyFeatures instead of<br>
removeFeatures - unless you call feature.destroy elsewhere.<br>
