Bit of a late reply, but I've been working on other aspects of the editor the 
past few days. Anyhow, that code I think was from an earlier version of 
OpenLayers which used feature IDs, not features.

Anyhow I've corrected it, but the change of style is still not permanent. See

http://www.free-map.org.uk/vector_test/

and try changing the style of any feature. It will change temporarily, but 
then when you select something else, it will go back to the old style. 
Current code to change the style:

        function refreshStyle(xmlHTTP,way)
        {
            alert('Changes uploaded to server. Response=' +
                xmlHTTP.responseText);
            var t = way.type;
            var colour = vectorLayer.routeTypes.getColour(t);
            var width = vectorLayer.routeTypes.getWidth(t);
            var style = { fillColor: colour, fillOpacity: 0.4,
                    strokeColor: colour, strokeOpacity: 1,
                    strokeWidth: width };
            vectorLayer.drawFeature(way,style);
            way.style=style;
        }

The code to determine the correct colour to use is fine, as the colour does 
initially change. But there seems to be something wrong with making the style 
permanent - at a guess, there's something wrong with the line 
"way.style=style".

Any ideas on this?
Thanks,
Nick
