AJAX requests on a mounted page with expired session
The situation:
I have a mounted page containing several AJAX components. Whenever the session expires and an AJAX request is triggered afterwards, a new instance of the page is (silently) created which is normal behavior I suppose (when looking at PageProvider.resolvePageInstance(…)).
Can I hook into that somehow? I'd like to show some custom please-restart-you-session-by-clicking-here ExpiredPage, but there's no PageExpiredException thrown (which is a good thing), but nevertheless I'd prefer to show something to the user.
Can someone point me into the right direction?
Cheers,
-Tom

Hi Thomas,
I was looking at the code, there isn't a central place creating a
PageProvider, which makes sense since it is designed to be created in
multiple ways. I had another idea and I think it is best to create a custom
MountedMapper that overrides the mapRequest method to implement your logic.

Yes, that was what I had in mind. But where can I configure my custom PageProvider (i.e. that Wicket knows that my PageProvider implementation should be used)?

Re: AJAX requests on a mounted page with expired session
Posted by Pedro Santos <pe...@gmail.com>.
You can override the PageProvider#getPageInstance method and test for the
target page class. If there are no instance for its page id and it is one
of those pages you want to reply to user a page expired message rather than
reply a fresh instance you throw a PageExpiredException exception (not
a StalePageException, StalePageException is for another case ).

Re: AJAX requests on a mounted page with expired session
Posted by Pedro Santos <pe...@gmail.com>.
Bleh, my bad, PageProvider will give you a fresh page since the
MountedMapper were able to resolve the target page class.
You can customize PageProvider to throw a StalePageException based on
custom rules. Don't know if it's the best option.

Re: AJAX requests on a mounted page with expired session

Can you give an example? AFAIK the pageId *is* already encoded in the URL bei Wicket, i.e. the URL changes to http://my.domain/foobar?0 when the page is rendered. Doing AJAX requests on the page does not change the URL though …

Hi Thomas, encoding the page ID in the URL would respond an expired page.
