> AbstractSingleSelectChoice makes it hard to customize the display values for null because it's hard coded to look it up by property keys. This is done in getDefaultChoice and it's not possible to change the behavior without overriding the whole method.
> I extracted getNullValidDisplayValue and getNullKeyDisplayValue which are then called in getDefaultChoice and default to the current behavior. Now subclasses can change these values easily.
