Increasing DiskPageStore.maxSizePerPageMap
Hello
I have a Wicket application (1.3.3) presenting a DataTable where each row
contains a link to open a ModalWindow. It works fine when the DataTable has
a few lines, but when more lines are added (say 40), the ModalWindow only
opens one; the second time we click on any of the ModalWindow links in the
DataTable, the session expires and the user is directed to the login page. I
debugged all the way into the Session.getPage() code and found that on the
second try the page is not found in the cache, causing the user session to
expire. I increased DiskStoreCache.maxSizePerPageMap through the debugger to
about 100MB and it solved the problem. I was wondering if that parameter can
be configured somehow, so we can mitigate the issue while we rework the code
to potentially reduce the pageMap cache size.
Thanks
Andre

Hi,
if you serialize object tree java serialization takes care of
"duplicate" or circular references.

If the same object is referenced twice, is it serialized twice?
Thanks for the tip on newSessionStore, it worked like a charm.

What gets there depends on what references you have in your page. All
non-transient references will be serialized.

Is there a simple way of finding out what's in the store? How do I control
what gets put in there?
Thanks

Look at webapplication#newsessionstore.
it is possible that you are serializing something huge, that's why it
doesn't fit in the store.

No errors in log. The page simply "disappears" from the cache.
I can see the parameter it in the constructor, but I don't have access to it
from my Page class. How do I get to construct the DiskPageStore myself?

It can be increased (look at DiskPageStore constructor), but it's
likely that your problem is somewhere else. Default size should be
plenty. Do you get any error in log?
