@SessionScoped bean looses scope and gets recreated all the time, fields become null

by

You’re using the wrong @SessionScoped annotation.

If you’ve registered the bean with the JSF @ManagedBean annotation, then you need to import the @SessionScoped from the JSF (javax.faces) package as follows:

import javax.faces.bean.SessionScoped;

When you incorrectly use a CDI scope on a JSF managed bean, then there is effectively no JSF scope for the JSF managed bean and it falls back to its default @RequestScoped, which creates a new instance in each HTTP request.

If you’ve registered the bean with the CDI @Named annotation, then you need to import the @SessionScoped from the CDI (javax.enterprise.context) package as follows:

import javax.enterprise.context.SessionScoped;

When you incorrectly use a JSF scope on a CDI managed bean, then there is effectively no CDI scope for the CDI managed bean and it falls back to its default @Dependent scope, which creates a new instance in each EL expression.
