No, you're certainly not stupid, it is not there. Sorry about that. You
can get it from Wicket stuff's CVS. I allways forget that there are a
lot of people who don't immediately start checking out projects from CVS
(as I do).
I've attached the two source files that matter. Have fun.

Thank you for your prompt reply.
I've been looking already for the cdapp, but I could not find it. I
looked at the sf downlaod page of Wicket and Wicket-Stuff and there
seems to be no download for wicket-contrib-examples. The only thing I
found was the running example at wicket-library - but no link to
download. Propably I am just too stupid to find it. Can you give me a
link?
Browsing the api I found a factory method for RequestCycle but this is
on Session (newRequestCycle) and is documented as wicket internal. Is
this the right method?
Thanks,
Christian

You can create your own RequestCycle implementation for this.
Override the factory method in (Web)Application to acchieve this.
See the cdapp example (wicket-contrib-examples of Wicket Stuff) for
an example of this (CdAppRequestCycle, CdAppRequestCycle).

Hi,
I want to bind the current Session to a thread-local for the current
request.
Is there a callback method which indicates a request-start and end.
Looking at the WicketServlet IMO I could use
WebApplication.newWebrequest() and override WebResponse.close().
However this seems a bit hacky. Is there a better way?
Thanks,
Christian
