Is it possible to call JSF events from an Inner Bean?

Question

Hi, i want to know if it is possible to call JSF events, such as a valueChangeListener and actionListener from an Inner bean, that is, a bean that is an objetc inside some other Managed Bean?

Thanks.

Yes, you can. You only need to make sure that the instance is available during the actual request.

E.g.

<h:inputText valueChangeListener="#{bean.nested.change}" />

in combination with

public class Bean {
    private Nested nested; // +getter
}

and

public class Nested {
    public void change(ValueChangeEvent event) {
        // ...
    }
}

is not going to work if Nested is not been instantiated in Bean. The #{bean.nested} would then return null and the method is unreachable. Thus, ensure that it is been instantiated:

public class Bean {
    private Nested nested = new Nested(); // +getter
}

EL namely won't do that for you.
