Hi,

Regarding this example:
http://dev.openlayers.org/releases/OpenLayers-2.11/examples/measure.html

I've tried to change the styling "on the fly" (while setImmediate(true)) if
the area exceed a certain value with something like this but it's not
working:

function handleMeasurements(event) {
    var geometry = event.geometry;
    var measure = event.measure;
    if (measure.toFixed(3) > 10000){
      new_style_properties = {'fillColor':'#FF3300','fillOpacity': .5,
'strokeColor': '#FF3300', 'strokeWidth': 2};
      new_style = new OpenLayers.Style();
      new_style.addRules([
          new OpenLayers.Rule({symbolizer: new_style_properties})
      ]);
      var new_styleMap = new OpenLayers.StyleMap({"default": new_style});
      drawControls.handlerOptions.layerOptions = {styleMap: new_styleMap}
    }
}

Can we change the layeroptions "on the fly" or it will only consider the
one set at creation time of the control?

regards,
