[OpenLayers-Users] Re: Box from GetFeature control, can this be polygon?

[MTrottier]

i'm a little lazy and don't want to add many tags in my mapfiles (many
mapfiles)
and i like this solution.

I found how to pass a polygon and receive a response.
I set my control like this :

 var control_wfs = new OpenLayers.Control.GetFeature({
					id: "CASERNE",
                    protocol: protocol_wfs,
					filterType: "INTERSECTS",
					maxFeatures: 100,
					multiple: true,
					multipleKey: "shiftKey"
});

but now i had a problem when calling my control like this :
mycontrol.request(polygon);

i got this error :
this.modifiers is null
error source line: [Stopper sur une erreur] if(!this.modifiers.multiple &&
!this.modifiers.toggle) {
GetFeature.js (ligne 478) 

so now my question is, what is this modifiers ?
and there is a solution to set de callback function ?
