Here's your first piece of advice with CDI and JSF - Never mix CDI with JSF annotations.

Your problem is that you use @javax.inject.Named a CDI annotation with javax.faces.bean.SessionScoped - a JSF annotation.

In CDI you would do:

import javax.enterprise.context.SessionScoped;
import javax.inject.Named;

@Named(value = "tableBeanLazy")
@SessionScoped
public class TableBeanLazy {...}

Note that the above will work perfectly fine with JSF.

In a pure JSF way you would do:

import javax.faces.bean.SessionScoped;
import javax.faces.bean.ManagedBean;

@ManagedBean(value = "tableBeanLazy")
@SessionScoped
public class TableBeanLazy {...}

I would recommend sticking with CDI all the way. However, CDI currently does not provide an alternative for the JSF @javax.faces.bean.ViewScoped out of the box. To get it in CDI look into Apache Deltaspike.
