Why not spring using my <String, Date> converter?

I have this in my applicationContext.xml

<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" />
<mvc:annotation-driven conversion-service="conversionService"/>
<bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
    <property name="converters">
        <set>
            <bean class="mycompany.AsOfDateConverter"/>
            <bean class="mycompany.CustomerConverter"/>
            <bean class="mycompany.FooConverter"/>
        </set>
    </property>
</bean>

AsOfDateConverter looks like

public class AsOfDateConverter implements Converter<String, Date> {
    @Override
    public Date convert(String source) {
        if(source == null) return new Date();
        //... else parse date. not shown.
    }

}

But Spring never picks up my DateConverter. Instead, I get it

org.springframework.beans.ConversionNotSupportedException: Failed to convert value of type 'java.lang.String' to required type 'java.util.Date'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [java.util.Date]: no matching editors or conversion strategy found
    at org.springframework.beans.SimpleTypeConverter.convertIfNecessary(SimpleTypeConverter.java:53)
    at org.springframework.validation.DataBinder.convertIfNecessary(DataBinder.java:534)
    at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.resolveRequestParam(HandlerMethodInvoker.java:506)

    at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.invokeHandlerMethod(HandlerMethodInvoker.java:170)

Two solutions are required: a) Why is he not using my converter? b) if the date is zero, can the converter still call my converter?

I have it all while working with PropertyEditors, but I need to port to Converters.

But I can't understand why Spring MVC is not using my DateConverter. I implemented it so that if the source
