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
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;
}
}
