Hey Martin,
So I put in my breakpoint and it looks like that my page store is
always empty, is always being invalidated by two repeated stack traces
that come in the following order:

This happens for each page request and as soon as a form is submitted
the back button redirects the user to the page expired for good reason
(page store is empty).
I also noticed that the work done for WICKET-3865 is not registering
the DebugPageManagerProvider which I added inside my init’s method via:
setPageManagerProvider(new
DebugPageManagerProvider(WicketApplication.this));
Please advise.

The second log leads to the problem. It seems the session is invalidated...
Put a breakpoint at
org.apache.wicket.pageStore.DefaultPageStore#removePageData and see
who calls it.

I think I found my answer here:

I'll grab the Wicket sources tomorrow and hook my IntelliJ IDEA
debugger to the DiskDataStore and work it backwards to see what happens.
Stay tuned... ;)
Have a great day,

Hey guys,
Just wondering what could be the cause of the many page expired
exceptions I am running into with this webapp whenever the user
changes tabs and then selects the browser’s “Back” button or whenever
the user downloads a resource via a button and the form is being
submitted a second time.
My first guess is that the page might have issues with its stateless
flags but help is welcomed as I’m still new to Wicket 6.x.
If needed I can create a quick-start.
The following is an example of the log right after the button has
been
hit a second time to submit the form:
