Spring webflow date binder - date

Question

I'm quite new working with webflow, and I having some troubles to make a custom converter for date binding (I need to changue the default pattern for 'dd-MM-yyyy')
So I'm trying to do something like this:
<view-state id="viewAnexos" view="myview" model="myModelBean">
<binder>
<binding property="anyDateOfTheBean" required="true" converter="customConverter"/> <!-- the type is java.util.Date -->
</binder>
<transition on="saveAnexo" to="viewAnexos" bind="true">
<evaluate expression="myController.saveAction(myModelBean, messageContext)" />
</transition>
</view-state>
And I've defined the ConversionService
#Service("conversionService")
public class FlowConversionService extends DefaultConversionService {
public void FlowConversionService() {
addDefaultConverters();
}
#Override
protected void addDefaultConverters() {
super.addDefaultConverters();
addConverter(new StringToDateCustomConverter());
addConverter("customCoverter,"new StringToDateCustomConverter()); //This method is deprecated, so how should I do it?
}
}
And the CustomConverter
public class StringToDateCustomConverter extends StringToObject {
private DateFormat format = null;
public StringToDateCustomConverter() {
super(StringToDateCustomConverter.class);
format = new SimpleDateFormat("dd/MM/yyyy");
}
#Override
protected Object toObject(String string, Class targetClass) throws ParseException {
return format.parse(string);
}
#Override
protected String toString(Object object) {
return format.format((Date) object);
}
}
And in my servlet.xml file, I've defined
<webflow:flow-builder-services
id="flowBuilderServices"
view-factory-creator="mvcViewFactoryCreator"
conversion-service="conversionService"/>
<bean id="conversionService" class="es.xunta.emprego.converter.FlowConversionService"/>
And after all this I'm having the next error:
org.springframework.binding.convert.ConversionExecutorNotFoundException: Custom ConversionExecutor with id 'customConverter' cannot convert from sourceClass [java.lang.String] to targetClass [java.util.Date]
Any ideas of what am I missing here..? Thanks in advance...

Answer 1

I've just changued a few things, and it works now.
1.-Renamed the StringToDateCustomConverter to StringToDate.
2.-The ConversionService has changued this way
#Service("conversionService")
public class FlowConversionService extends DefaultConversionService {
#Override
protected void addDefaultConverters() {
super.addDefaultConverters();
addConverter(new StringToDate()); //This is overrided
}
}
3.-The binder in the flow.xml is not necessary anymore, so...
<view-state id="viewAnexos" view="myview" model="myModelBean">
<transition on="saveAnexo" to="viewAnexos" bind="true">
<evaluate expression="myController.saveAction(myModelBean, messageContext)" />
</transition>
</view-state>
And that's it, it's working fine!!
