[OpenLayers-Users] howto regist. featuremodified instead onModification ?

[Alexandre Dube]

Well, I don't 100% understand.  Using on, what's the use of the scope ?  
The following works without scope :

        olWFSRoads.events.on({
            featuremodified: function(o) {
                var oFeature = o.feature;
                OpenLayers.Console.log("modified", oFeature.id);
            }
        });


or the following works also, but scope is still useless here.

        olWFSRoads.events.on({
            featuremodified: function(o) {
                onRoadModification(o.feature);
            },
            scope: this
        });

function onRoadModification(object) {
    var oFeature = object.feature;
    OpenLayers.Console.log("modified", oFeature.id);
};


In the end, I want to move my OpenLayers demo into MapFish and I want to 
use some widgets like the list of features which uses a Modification 
control.  It already has its own defined onModification function, so I 
have to get rid of mine and register an event instead.  Using one of the 
above method should do the trick, I am correct ?

Thanks again for your help,

Alexandre
