When logging out of an application, I wanted to remove the session associated with the user. To do this I ended up with the following:
<h:commandLink action="#{logoutBean.testAction}" value="#{menu.FILE_EXIT}" />
...
public String testAction()
{
FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
return "/login.xhtml";
}
This has the desired effect in destroying the session and returning to the login page, but I generate an exception in the background:

Two questions:
1. Is this the correct approach ?, if not, what do you recommend ?
2. If yes, how do I deal with the exception
