Question

I am trying to initialize a backing bean on page load. Already looked for many solutions, but most of them are using links,buttons or not having parameters at all.

scenario:
A customer logins to a site and then should see all of his data on the following page.

backing beans:

1. loginDetailsController – to support
   login process. Can access user’s
   password and username. Backing bean
   for Login.xhtml.

2. customerController – to access the
   rest of user details. It also has a customer_id field. It is the Backing bean
   for Home.xhtml. It is possible to initialize customerController entirely from customer_id.

On Home.xhtml it is possible to get customer_id this way:

 #{loginDetailsController.customer_id}

Is there a way to initialize customerController with the above value on page load?

Regards,

Daniel

Answer 1

This is how I solved it:

Because LoginDetailsController is session scoped – customer_id is always initialized.

So – I added

@ManagedProperty(value="#{loginDetailsController.customer_id}") 
private String customer_id;

Plus – getter and setter for customer_id.

On LoginDetailsController, as Nikhil said – with a little change.
Then, it is possible to use #{customerController.customer_id} and the rest of customerController initialized elements of customerController on Home.xhtml.

Thank you all!
