[jira] [Created] (WICKET-5006) Improve null display value in AbstractSingleSelectChoice

Christoph Leiter created WICKET-5006:
----------------------------------------

             Summary: Improve null display value in AbstractSingleSelectChoice
                 Key: WICKET-5006
                 URL: https://issues.apache.org/jira/browse/WICKET-5006
             Project: Wicket
          Issue Type: Improvement
          Components: wicket
    Affects Versions: 6.5.0
            Reporter: Christoph Leiter
            Priority: Minor


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.
