docs: This method tries to map the values of the given object on the valueModels of the formModel. Instead of
  setting the object as a backing object, all valueModels are processed one by one and the corresponding
  property value is fetched from the objectToMap and set on that valueModel. This triggers the usual
  buffering etc. just as if the user entered the values.
