They use choice renderers as well as converters.
IChoiceRenderer.getDisplayValue returns an Object that gets converted
to a string. This is from AbstractChoice in Wicket 1.2:
protected void appendOptionHtml(AppendingStringBuffer buffer, Object
choice, int index,
String selected)
{
final String displayValue = (String)getConverter().convert(
renderer.getDisplayValue(choice), String.class);
...
Has this changed in 1.3?

Hi,
I implemented a custom Converter. It looks like this:
public class AnredeConverter implements IConverter {
public Object convertToObject(String arg0, Locale arg1) {
if(arg0 == null) return null;
return Anrede.fromString(arg0);
}
public String convertToString(Object obj, Locale locale) {
Anrede an = (Anrede) obj;
return an.getValue();
}
}
The I added it to the apllication:
@Override
protected IConverterLocator newConverterLocator() {
ConverterLocator converterLocator = new ConverterLocator();
converterLocator.set(Anrede.class, new AnredeConverter());
return converterLocator;
}
I use it for a DropDownChoice
DropDownChoice anrede = new DropDownChoice("anrede", new
PropertyModel(ma,
"anrede"), Anrede.literals());
add(anrede);
My problem is that the convertToString-Method is never called, so
that the
DropDownChoice is not set to the right value.The convertToObject-
Method
works fine.
How can I tell the DropDownChoice to use the Converter to get the
right
value.
Thanks in advance,
Benjamin
