/**
* Use this controller when you need to override the way the backing object is created.
* If all you are doing is return new MyBackingObject() you won't need to implement this,
* Spring will handle that for you. Do not use this method to populate helping data
* into the model. This method does not get called if there is an error in validation.
* If you rely on this information for putting stuff in the request, you will not have
* it there in the case of validation error. If you need to put helping data in the model,
* implement FormController's referenceData method.
