[OpenLayers-Users] no element found with OpenLayers.Request

[Moataz Elmasry]

Hello List

I'm creating a feature with the features-edit tool and then committing 
this feature to some server in geojson format.

It looks as follows:
OpenLayers.Request.POST({
            url: Pronto.consts.Mapservice.URL.Base,
            callback: this.featureHandler,
            scope: this,
            headers: {
                "Content-Type": "text/plain"
            },

            params : {
                geojson : serializedJson,
                featureid : featureId,
                featuretype : Pronto.consts.layer.id.Annotation,
                action : "create"
                }
        });

and the handler:
featureHandler : function(request) {
        console.log(request);
    }


Everything on the firebug looks ok. but in web developer toolbar I get 
the error:
Error: no element found
