Hmm, excuse me... but it seems to be that you could accomplish exactly
what you are asking for by hooking beginRequest(), endRequest() methods
to open and close your Hibernate session. Hibernate conventions
discourage the use of long-term sessions so this is actually what you
should be doing. Opening a new Session is dirt cheap.

Storing the hibernate session in my wicket.Session would make it impossible to

I know that you guys are very careful about what methods to expose to us Wicket
users, but perhaps the final on Session#getPage(String,String,int) could be
dropped?
I'm in need for this for another thing too:
My pages get their dependencies through Spring (utilizing a custom
PageFactory) and hold them in transient members.
When a session (and its pages) gets serialized/deserialized all dependencies
are lost. What I really would like to have is the opportunity to reinject these
dependencies before any code is triggered on this pages.
Thanks

I think it is a better idea to store the current session in your
wicket.Session object (you can create your custom session objects by
providing your own ISessionFactory, which can be done by overriding
Application.getSessionFactory. For the housholding, you could best use
a custom request cycle (override
wicket.protocol.http.WebSession#getRequestCycleFactory()) and
override onBeginRequest and onEndRequest.
The problem with trying to do this with pages, is that there is no
guarantee that the same page is called at the end of the request; any
listener code code code set another page for rendering.
One of the things we should do for 1.2. is further formalize our
request handling and adding clear hooks into it.

Hello,
I'm in need for a notification when a wicket page is accessed, i.e. when a
component listener is invoked.
Why?
I want to use Hibernate 'application transactions'
(http://www.hibernate.org/168.html): Each wicket page has its own Hibernate
session which is kept open until the corresponding use case ends.
What I have to do is disconnect() and reconnect() the Hibernate session for
each request to this page.
But I cannot find a hook in Wicket, where I could do this housekeeping
*before* my code on that page is triggered. All my investigations are running
into private and final methods :(.
Does anybody have an idea for this scenario? Did I miss something?
Any chance that some sort of 'page interceptor facility' could be
incorporated into Wicket?
Thanks
Sven
