Değişken Null Değer Dönüyor

JSF uygulamada kullanıcının giriş yapmasının akabinde ona ait bilgileri çekecek bir sınıf yazdım. Bu sınıfta fillList metodu ile kullanıcıya ait bilgileri değişkenlere set edeceğim. Fakat metodun bitiminin ardından değişkenler yine null değerlerine dönüyorlar. Static yaparsam sorun çözülüyor ancak ben static olmayınca neden olmadığını öğrenmek istiyorum. JSF sayfasında olması gereken değer gelmiyor. Kod şöyle: package com.ilkgunel.hastaneotomasyonu.controller;
