Signature of f:ajax listener in JSF2.2

Question

In my project I am using f:ajax listener with arguments like this:

    <h:inputText value="#{myBean.person.name}">
        <f:ajax 
            event="change" 
            listener="#{myBean.doSomething(myBean.person.id)}" />
    </h:inputText>  

with a listener in MyBean

    public void doSomething(Integer id)
    {
        // do something with id ...
    }

The Oracle Documentation f:ajax says that the signature of the listener for f:ajax must match the following:

public void processAjaxBehavior(javax.faces.event.AjaxBehaviorEvent event) throws javax.faces.event.AbortProcessingException) 

So according to the Oracle Documentation it should be done like this:

    <h:inputText value="#{myBean.person.name}">
        <f:attribute  
            name="identifier" 
            value="#{myBean.id}"/>
        <f:ajax 
            event="change" 
            listener="#{myBean.doSomething}" />
    </h:inputText>  

with a listener in MyBean

    public void doSomething(AjaxBehaviorEvent event) throws AbortProcessingException
    {
        Integer id = (Integer) event.getComponent().getAttributes().get("identifier");
        // do something with id ...
    }

Both examples work in my application. But the first example is very intuitive and more easy to use.

Are there arguments against using the listener with parameters other than AjaxBehaviorEvent?
