I think the answer of ali saleh is right.

If you get problems with the tabchangelistener perhaps this can help you:

I had a similar problem with Primefaces 5.1

As long as i put the tabview into a form everything worked fine. But because i wanted to use seperate forms in my tabs i had to remove the surrounding form of the tabview to avoid nested forms. Without the surrounding form the ajax event didn´t get triggered any more when changing the tab.

My solution was to use a remotecommand in a form parallel to the tabview.
The remotecommand is triggered by the onTabChange attribute of the tabview element. At that call i forwarded the index parameter to the global request parameters.

    // Tabs...  



    
    

In the backing bean i catched the value again from the request parameter map and set the active index.

public void onTabChange()
{   
    FacesContext context = FacesContext.getCurrentInstance();
    Map paramMap = context.getExternalContext().getRequestParameterMap();
    String paramIndex = paramMap.get("activeIndex");
    setActiveTabIndex(Integer.valueOf(paramIndex));
    System.out.println("Active index changed to " + activeTabIndex);
}    

Hope that can help you
