Who has the focus?

[Wander Soares]

I need to know where the focus of the application is in the server side, i.e., i need to know in the backingbean where the focus is. Any idea?

Could you explain better what you need, because you mean focus ???

What component of the aplication(textboxs,buttons,...) has the focus,i.e, is selected.

Hi wandroide

First above all I suggest you read about the JSF request process lifecycle and understand all phases as soon a request is produced until de page is rendered.
I suggest you also read about the MVC model, wich is where it is based jsf.
That said, when in the client (browser) a component is selected (has the focus) the server does not know anything about this, becuase have not been a request to the server.
One solution to know the component that has the focus in the server is using ajax, you can make a partial request for all components you want when any component has the focus.
If you're using JSF 2.0 you can do it like this:
<h:form > <f:ajax event="focus" listener="#{testBean.testAjax}"> <h:inputText /> <h:inputText/> <h:selectOneMenu/> </f:ajax> </h:form>
All the component's between the <f:ajax> and </f:ajax> make a partial request for the onfocus event and call the method especified by the listener attribute
And the method for the listener

public void testAjax(AjaxBehaviorEvent event) {
        UIComponent com = event.getComponent();
        String id =com.getClientId();        
}

I hope this can help you to solve your problem, sorry for my English.
