Major Description
Each time a user initiates a post back, another view is serialized in the session. As a result, if the user does 20 postbacks (the default number of views to save) any other open views quickly get a ViewExpiredException.
1) Deploy the example below
2) Open a browser with a window to the page (http://localhost:8080/Web for example)
3) Open another tab in the same browser to the same page (or whatever you need to do in your browser to ensure the two pages share a session)
4) On the first page, click "Update foo" button 20 times.
5) Now go to the second page and click "Update foo".
6) Notice the ViewExpiredException
@ManagedBean
@SessionScoped
public class testBackingBean implements Serializable{
private String msg="foobar";
public String getMsg()
{ return msg; }public void setMsg(String msg)
{ this.msg = msg; }}
