Martin Grigorov resolved WICKET-4360.
-------------------------------------
Resolution: Not A Problem
On F5 Wicket reads (once) the current page.
But then it writes a the page with a new page id because of the usage of
ListView (PropertyListView in DataPanel).
By adding "commentsListView.setReuseItems(true);" all is fine.
See WICKET-4286 for a discussion about the ListView problem.

> Key: WICKET-4360
> URL: https://issues.apache.org/jira/browse/WICKET-4360
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5.3
> Environment: Windows & linux, jetty 7 & WAS 7
> Reporter: Stijn Geukens
> Attachments: wicket4360.zip
>
>
> This issue was first reported on StackOverflow but after further
> investigation it is possible that this is a bug:
> http://stackoverflow.com/questions/8985785/wicket-serialization-deserialization-issue
> I added following to my Page class:
> private void writeObject(ObjectOutputStream oos) throws IOException {
> oos.defaultWriteObject();
> System.err.println("Writing " + this + something to print out
> the type of the filter);
> }
> private void readObject(ObjectInputStream ois) throws
> ClassNotFoundException, IOException {
> ois.defaultReadObject();
> System.err.println("Reading " + this + something to print out
> the type of the filter);
> }
> 1. When the Page is loaded first it prints (actually it prints this 5 times,
> not sure if it's normal):
> Writing [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 0, render
> count = 1]: type = ALL
> 2. When I click on AjaxLink 'ALL' (that will update the filter) it still
> prints:
> Writing [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 0, render
> count = 1]: type = ALL
> 3. When I click on AjaxLink 'DISCUSSIONS' (that will update the filter) it
> still prints:
> Writing [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 0, render
> count = 1]: type = DISCUSSIONS
> 4. When I refresh the page (F5) the pageid is updated:
> Writing [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 1, render
> count = 2]: type = DISCUSSIONS
> The url however does not change, it stays http://.../?0
> 5. When I click on AjaxLink 'ALL' (that will update the filter) it prints:
> Writing [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 1, render
> count = 1]: type = ALL
> So far so good but
> 6. When I refresh the page now (F5) this is printed out:
> Reading [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 0, render
> count = 1]: type = DISCUSSIONS
> Writing [Page class = com.bnpp.ecom.homepage.web.Homepage, id = 2, render
> count = 2]: type = DISCUSSIONS
> So it deserializes the page with id 0 although the last known page id was 1
> and all changes that were done for version 1 are ignored (in this case
> switching the type from DISCUSSIONS to ALL).
