Dear Jan,<br><br>I have tried to declare the control also as in your example. It did not work either.<br>In the meantime, I have localized the problem although I do not have a solution to it yet.<br><br>Turns out that if I remove style declaration the modify tool works.<br>
<br>With this the modifyFeature does not work:<br>var regions = new OpenLayers.Layer.Vector("regions",{extractAttributes:true, format: OpenLayers.Format.GeoJSON, projection: new OpenLayers.Projection("EPSG:4326"), <span style="color: rgb(255, 0, 0);">styleMap: new OpenLayers.StyleMap(mystyle)</span>});<br>
<br>With this it works<br>var regions = new
OpenLayers.Layer.Vector("regions",{extractAttributes:true, format:
OpenLayers.Format.GeoJSON, projection: new
OpenLayers.Projection("EPSG:4326")});<br><br>However, the style is quite necessary because depending on properties (attributes) I store in GeoJSON array, I have rules to change style of features when rendered. It seems that this interferes somehow with the select style of modifyFeature controlo. Or...<br>
<br>Hopefully, I will find a solution to keep them both. Otherwise, is there a way to migrate features from one vector layer to another? <br><br>All the best,<br>Adorian<br><br><br>

GeoJSON layer and modifyFeature control<br></font><br></div>
<div>
<div></div>
<div>
<div></div>Hi,<br><br>I have a very simple question: is it possible to modify
features in a layer populated from a GeoJSON file? I am asking just about
modifying feature on map without the saving part.<br>I did add the
modifyFeature control, but I cannot select and modify any of the polygons in
this layer ( var regions = new
OpenLayers.Layer.Vector("regions",{extractAttributes:true, format:
OpenLayers.Format.GeoJSON, projection: new OpenLayers.Projection("EPSG:4326"),
styleMap: new OpenLayers.StyleMap(mystyle)});)<br>Another modifyFeature
control works OK on a second vector layer (var vectors = new
OpenLayers.Layer.Vector("vectors");). <br><br>All the
