Hi Ricardo
You can also get into these errors if you do not use detachable models,
and not use extended persistence context (if using JPA).. BTW using
extended persistence context are not recommended, due to performance
reasons AFAIK..

Hi Yann,
Thanks for your response. The problem occurs when I try to load an entity in
a WebPage object.
A common solution for this is to use Open Session in View filter, but it
didn't work.
So I found the problem. I was manually creating a spring context to inject
objects in the web page. The right thing to do is to use wicket spring
integration:

Hi Ricardo,
May be I'm wrong but this kind of exception has nothing to do with Wicket.
This exception is usually sent by Hibernate when trying to load a
collection
with lazy option to true on a detached object.
I'd be a great help if you could post your mapping file, the stacktrace of
the exception and maybe a few code lines where the exception occured if
this
is in your code and not in wicket sources.
(may you'll find more help on an hibernate list )

Hi all,
I'm getting a LazyInitializationException when using wicket + spring +
hibernate. I'm declaring Open Session in View filter before wicket
filter.
My configurations goes bellow. Any help is appreciated:

There are three means to configure Wickets configuration

they are
tested in the order given.
1) A system property: -Dwicket.configuration
2) servlet specific <init-param>
3) context specific <context-param>
The value might be either "development" (reloading when
templates
change)
or "deployment". If no configuration is found, "development"
is the
default.
