viewScoped bean dies too soon thow the issue does not occur when the project is run from netbeans

Question

excuse me to borther once more actually I've been through an issue for a long while I tried to flick through variours post on various forum without finding a solution. I developped a web application with Hibernate, Spring and PrimeFaces; everything was fine until I decided to deploy on another tomcat different from the one used by netbeans. when I deploy it on the other Tomcat, the project works well for everything related to @RequestScoped bean but for @ViewScoped bean it is not the case, @ViewScoped bean seems to die as soon as it is created

here is one of my bean
