      Description

      When mapping a widget to a model, QDataWidgetMapper::mappedPropertyName returns an empty "" string if the property is not specified during addMapping(). This behavior is incorrect because although you don't specify the property, a default one is selected for you. The documentation also makes no mention that the empty string is returned in this case.
