[OpenLayers-Users] OpenLayers.Class withOpenLayers.Control.GetFeature

[Gery .]

thanks Arnd, I added your suggestion and it still complains about the same but after some a couple of clicks or boxes it sends the request, however the sent bbox is still in UTM, where could the problem be? here you can take a look at the code:
var mycontrol = function(){
            var protocol = new OpenLayers.Protocol.HTTP({
                url: 'http://www.r2d2.starwars/',
                format: new OpenLayers.Format.GeoJSON({
                    ignoreExtraDims: true,
                    'internalProjection': new OpenLayers.Projection('EPSG:900913'),
                    'externalProjection': new OpenLayers.Projection('EPSG:4326')
                })
            });

            OpenLayers.Control.myGetFeature = OpenLayers.Class(OpenLayers.Control.GetFeature,{
                selectBox: function(position){
                    var opts = OpenLayers.Control.GetFeature(position);
                    var baseSRSutm = this.map.getprojectionObject();
                    console.log('this is the baseSRSutm' + baseSRSutm);                     <--- this console.log doesnt appear in firebug
                    var layerSRSdd = new OpenLayers.Projection('EPSG:4326');
                    opts.params.bbox = this.map.getExtent().transform(baseSRSutm,layerSRSdd).toBBOX(null,firstLayer.reverseAxisOrder());
                    console.log('this is the opts.params.bbox' + opts.params.bbox);      <--- this console.log doesnt appear in firebug
                    return opts;
                },
                CLASS_NAME: "OpenLayers.Control.myGetFeature"
            });
 
          return new OpenLayers.Control.myGetFeature({
                protocol: protocol,
                box: true,
                click: true,
                single: false,
                clickTolerance: 10,
                eventListeners:{
                    // May the Force be with you
                }
            });
        };

because the console.log doesnt appear in firebug, I think the problem is in the OpenLayers.Control.myGetFeature and OpenLayers.Class. It seems to me that the "selectBox" function is the one I need, but the subclass itself is not read by the return.

try 
this:
...
opts.params.bbox = 
...
return opts;
},
CLASS_NAME: 
"OpenLayers.myGetFeature"
});

It seems, that a class needs a CLASS_NAME.

Thanks for that Arnd, now it 
stops complaining about the missing "}", but now it appears 
"TypeError: 
this.CLASS_NAME is undefined", what and where should I put 
there?

Hi,
 
move 'return opts;' into the function 
body:
...
opts.params.bbox = ...
return opts;
}
 
to get rid of 
the error.

OpenLayers.Class withOpenLayers.Control.GetFeature




Hi 
all,

I'm wondering if someone could point me in the right 
direction to force the BBOX 
of OpenLayers.Control.GetFeature to be always in long/lat coordinates. I'm trying 
to get this with OpenLayers.Class, so 
the new control will inherit 
OpenLayers.Control.GetFeature with just the small modification in BBOX. This is what I've 
done:

OpenLayers.Control.myGetFeature = 
OpenLayers.Class(OpenLayers.Control.GetFeature,{ 
        
    selectBox: function(position){ 
        
        var opts = OpenLayers.Control.GetFeature(position); 

                var baseSRSutm = 
this.map.getprojectionObject(); 
            
    var layerSRSdd = new OpenLayers.Projection('EPSG:4326'); 

                opts.params.bbox = 
this.map.getExtent().transform(baseSRSutm,layerSRSdd).toBBOX(null,firstLayer.reverseAxisOrder()); 

            }
        
    return opts; 
        }); 

 
but I'm getting that some "}" are missing. Is this the right way to use OpenLayers.Class to do what I want?

Any help is much appreciated.

Gery
