I've been trying to follow this example and using the reference to guide me, but I'm having no luck.
I've defined a converter:
import org.springframework.binding.convert.converters.StringToObject;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.text.ParseException;
import java.util.Date;
public class StringToDateTwoWayConverter extends StringToObject {
private DateFormat format = null;
public StringToDateTwoWayConverter () {
super(StringToDateTwoWayConverter.class);
format = new SimpleDateFormat("MM/dd/yyyy");
}
@Override
protected Object toObject(String string, Class targetClass) throws Exception {
Date date = null;
try {
date = format.parse(string);
} catch (ParseException e) {
e.printStackTrace();
return null;
}
return date;
}
@Override
protected String toString(Object object) throws Exception {
Date date = (Date) object;
return format.format(date);
}
}
and a conversionService:
import org.springframework.binding.convert.service.DefaultConversionService;
import org.springframework.stereotype.Component;
@Component("conversionService")
public class ApplicationConversionService extends DefaultConversionService
{
@Override
protected void addDefaultConverters() {
super.addDefaultConverters();
this.addConverter(new StringToDateTwoWayConverter());
this.addConverter("shortDate", new StringToDateTwoWayConverter());
}
}
and configured it:
<webflow:flow-builder-services id="flowBuilderServices" conversion-service="conversionService" .../>
However, upon startup, I'm greeted with this exception:
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '(inner bean)': Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.core.convert.ConversionService]: Could not convert constructor argument value of type [com.yadayada.converter.ApplicationConversionService] to required type [org.springframework.core.convert.ConversionService]: Failed to convert value of type 'com.yadayada.converter.ApplicationConversionService' to required type 'org.springframework.core.convert.ConversionService'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.yadayada.converter.ApplicationConversionService] to required type [org.springframework.core.convert.ConversionService]: no matching editors or conversion strategy found

I'm thoroughly puzzled why its not working. The conversion service implements ConversionService through its base class, so I don't see the problem. Any insight much appreciated!
