[OpenLayers-Users] addUniqueValueRules and selection circles

[Jelmer Baas]

Hello list,

First of all, I apologize for sending this message again. After numerous
experiments, I still haven't found a solution for my styleMap problem. 

The only thing I actually want is after inserting a new feature into a
layer, to give that feature some style properties. Somehow I find it
hard to believe I need to fiddle with stylemaps, a bunch of styles, etc
to achieve that.

I expected this:
controls.polygon.events.register("featureadded",'' , roadFeatureAdded);

function roadFeatureAdded(object){
	object.style.strokeColor='red';
}

At any rate, does anyone why my edit circles won't show up (see below),
or how I can achieve what I described in the fasted way possible?

Regards,
Jelmer Baas
