SecondLevelCache + DiskPageStore Serialization issue with Anonymous inner
classes
---------------------------------------------------------------------------------
Key: WICKET-2138
URL: https://issues.apache.org/jira/browse/WICKET-2138
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4-RC2
Environment: Solaris/JDK6u10 Jetty clustered session store.
Reporter: Victor Igumnov
It seems like declaring an anonymous inner class will hold on to the previous
page which will break serialization with secondlevelcache in a clustered
environment.

I have run into an odd issue with serialization which throws a stackoverflow
exception. Here is the cause:
Passing an LDM model as-is to a page, it will stackoverflow on the receiving
page, if that page is refreshed twice or a form has been submitted.
Here is an example...
setResponsePage(new EditBlogPage(new LoadableDetachableModel<Blog>() {
private static final long serialVersionUID = 1L;
@Override
protected Blog load() {
// just an example....
return new Blog();
}
}));
However, if I subclass the LDM and pass it like so, it will work just fine.
public class FakeLDM extends LoadableDetachableModel<Blog> {
private static final long serialVersionUID = 1L;
@Override
protected Blog load() {
return new Blog();
}
}
setResponsePage(new EditBlogPage(new FakeLDM()));
One last thing, If I construct the LDM inside the receiving page. It will work
fine as well.
This seems to only happen with the SecondLevelCache, any ideas?
