There are two major means of data binding initialization, but there is a drawback in the oldschool one, that I can't figure out. This annotation way is great :

```
@InitBinder("order")
public void initBinder(WebDataBinder binder) {
    // Problem is that I want to set allowed and restricted fields - can be done here
    binder.setAllowedFields(allowedFields.split(","));
}

```

but I can't be done with ConfigurableWebBindingInitializer. First off, the binder instance is created in AnnotationMethodHandlerAdapter and initializer is passed the binder instance somewhere in HandlerMethodInvoker so I can't set it up... I can't do something like this :

```
<bean id="codesResolver" class="org.springframework.validation.DefaultMessageCodesResolver" />
<bean id="binder" class="org.springframework.web.portlet.bind.PortletRequestDataBinder" scope="prototype">
    <property name="allowedFields" value="${allowedFields}" />
    <aop:scoped-proxy />
</bean>
<bean id="webBindingInitializer" class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
    <property name="messageCodesResolver" ref="codesResolver" />
</bean>

```

Because binder instance is passed into it in handlerAdapter. How can I set up the binder then ?
