OK, I managed to "fix" the problem. And here`s how:
I used to have Form class injected in page, then Dao class injected in
form, then hibernate session injected in dao class and that session was
the one causing WicketNotSerializableException. But, when I create the
form with new, it all goes away. While this will work, I still think it
would be more... well, neat to have components injected on page.
Some things you may look at
IComponentInitalizationListener --
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/application/IComponentInitializationListener.html
IComponentInstantiationListener --
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/application/IComponentInstantiationListener.html
If your really wanting to use Guice/Spring have you considered using a
panel/component and implementing your own provider/factory for the
component? I'ts almost always harder to do this sort of thing with a Page.

Thanks, that does offer more flexibility, but it hasn`t solved my
problem yet. Guicier and wicket-guice both return objects with
wicket, not guice proxy when I say something like
setResponse(HomePage.class). If I inject my page object and say,
for example, setResponse(injectedPage) it works fine, but I can`t
stick to that course throughout my application, because
Application.getHome() returns Class<? extends Page>.
By the way, the application doesn`t crash, it only throws
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:
Unable to serialize class: com.google.inject.InjectorImpl$4 and
then it continues doing whatever it was doing.
I found that similar issue was raised before
<http://osdir.com/ml/users-wicket.apache.org/2009-06/msg01059.html>,
if it was resolved I would be happy to know. :)
Take a look at http://code.google.com/p/jolira-tools/wiki/guicier
<http://code.google.com/p/jolira-tools/wiki/guicier>There is
an extended
integration with Guice.

Sorry for spamming, but I remembered another thing I would
like to ask
related to this. The reason why I need to inject a page is
because I would
like to use guice AOP feature to wrap an interceptor
around wicket pages. If
you can recommend another way to do that , it would be
helpful as well. I
did a quick scan through wicket documentation, but
couldn`t find anything
useful. Maybe I missed something?

Hi all,
I have guice integrated in my wicket app, and it
worked fine until I tried
to inject a page, when I received
java.lang.IllegalArgumentException: Protected method:
checkHierarchyChange(Lorg/apache/wicket/Component;)
Now, I assume this is because of guice integration
pitfall<
https://cwiki.apache.org/WICKET/guice-integration-pitfall.html>,
as I
clearly cannot use interfaces here, but the proposed
solution (with
deprecated protected no-arg constructor) doesn`t help
me here. Any idea how
to get around this?
Thanks in advance,
Dan
