[OpenLayers-Users] Measure Control interfering with Drawing Control

[Franz Buchinger]

My map hosts a measure and a drawing control. The first should obviously
perform client-side measuring, the drawing control should post the drawn
geometry to the server on the featureAdded event.
The problem: after switching from drawing to measuring, the measuring
control mimics the behaviour of the drawing control: the measurement
geometry is also posted to the server after completing the measurement.

To circumvent this, I tried to restrict the controls to different vector
layers, but had no success so far. Here is the relevant code snippet:

var plotLayer = new OpenLayers.Layer.Vector();
var drawControl = new OpenLayers.Control.DrawFeature(
        plotLayer, OpenLayers.Handler.Path,{  //plotLayer = vector layer
for drawing control
        handlerOptions: {maxVertices: 2, freehandMode: function
(evt){return false;}},
        featureAdded: function(feature){
            var drawnLine = feature;
            var drawnLinePoints = feature.geometry.getVertices();
            $.post ('webservice.url', {line: drawnLinePoints},
function(response){
                self.displayPlots(response);
            })
         }
    });
var measureControl = new OpenLayers.Control.Measure(
    OpenLayers.Handler.Path, {
        persist: true,
        layer: map.getLayersByName('vector')[0] //vector layer for measure
control
    }
);
map.addControls([drawControl,measureControl]);

any ideas?

thanks,

Franz
