Martin Kočí commented on MYFACES-3100:
--------------------------------------
Yes, but this is the nature of state saving: new request/response always
creates new saved state. But we really can drop old ones: therefore I created
MYFACES-3117.
> Repeated postbacks create additional serialized views

> Key: MYFACES-3100
> URL: https://issues.apache.org/jira/browse/MYFACES-3100
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 2.0.4
> Environment: JBoss 6.0.0.FINAL, MyFaces 2.0.4
> Reporter: Robert M. Gary
> Original Estimate: 72h
> Remaining Estimate: 72h

> 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;
> }
