when creating an new qx.data.store.Jsonp object like this...
var store = new qx.data.store.Jsonp(url, {
configureRequest: function(req) {
req.setParameter("key", "resources.appsrvs");
}
},"callback");
... the delegate function configureRequest does not get the request as parameter as described in qx.data.storeInterface.IStoreDelegate. so how can i configure the request?
