ic.ajax problem

ic.ajax.js

// This works:
return ic.ajax(url).then(function (response) {});


// This throws following error:
return ic.ajax.request({
  type: "PUT",
  url: url
}).then(function (response) {});
// TypeError: undefined is not a function

// And this is interesting:
console.log('ic:');
console.log(ic);
console.log('ic.ajax:');
console.log(ic.ajax);
console.log('ic.ajax.request():');
console.log(ic.ajax.request());

// ic:
// Object {ajax: function}

// ic.ajax:
// function ajax(){return ajax.raw.apply(null,arguments).then(function(result){return result.response},null,"ic-ajax: unwrap raw ajax response")}

// ic.ajax.request():
// TypeError: undefined is not a function

// Finally resolved by using .raw()

return ic.ajax.raw({
  type: "PUT",
  url: url
}).then(function (response) {});

I assume url is defined... stupid question I know...
