----------------------------------------
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.
