Call session scoped bean method on every view

Question

Perhaps this is a question I should be able to find documentation on, but I'm unfamiliar with a lot of the jargon so I'm struggling.

Basically, I'm using JSF2. I have a SessionScoped bean, and it uses a postconstruct init() method. I want the init() method to be called everytime the session starts, which works fine, but I also want it to be called every time the view loads.

Is there an easy way to do this?

Thanks!

Replace @PostConstruct by <f:event type="preRenderView">.

<f:event type="preRenderView" listener="#{sessionScopedBean.init}" />

Better, however, is to split it into 2 beans: a @SessionScoped one and a @ViewScoped one. Then just reference the @ViewScoped one in the view instead and inject the @SessionScoped one as a property of the @ViewScoped one.

@Named
@ViewScoped
public class ViewScopedBean {

    @Inject
    private SessionScopedBean sessionScopedBean;

    @PostConstruct
    public void init() {
        // ...
    }

    // ...
}
