AbstractSingleSelectChoice: custom resource key for null option
---------------------------------------------------------------
Key: WICKET-2428
URL: https://issues.apache.org/jira/browse/WICKET-2428
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 1.4.0
Reporter: Fridolin Jackstadt
Is it possible to refactor AbstractSingleSelectChoice like shown below? To be
able to override getNullOptionKey would give a great value for us.
This would allow to have the display-values of null-options in a singel
properties file for whole project even if ids of some choices with different
null-option display-values are equal.
protected String getNullOptionKey() {
return getId() + ".nullValid";
}
if (isNullValid())
{
// Null is valid, so look up the value for it
String option =
getLocalizer().getStringIgnoreSettings(getNullOptionKey(), this,
null, null);
if (Strings.isEmpty(option))
{
option = getLocalizer().getString("nullValid", this, "");
}
....
