Lazy loading exception despite of OpenSessionInViewFilter and
object loading within a request
Hi
I've got some issues with the OpenSessionInViewFilter I integrated into a
Wicket application to get rid of the LazyLoadingException problem.
So my problem is. I got a login page with a SignInPanel. When a user tries
to log into the web site his credentials are passed to the authentication()
method of a Session class which extends AuthenticatedWebSession. In this
method a AuthenticationService tries to load the user form the database,
when it succeeds the user is stored in the session. The method in the
AuthenticationService class which loads the user is annotated with
@Transactional. After the user is loaded procession of the request goes on.
During this getRoles() of the session class is called to check the user's
rights. Therefore getRoles() gets called on the user which was stored in the
session before. getRoles() should normally lazy loads the roles of the user
but unfortunately a LazyLoadingException is thrown.
This behavior is really strange as I thought the OpenSessionInViewFilter
takes care that all requests to the database within on web request use the
same session.
To examine this issue further I activate logging on the
OpenSessionInViewFilter. This shows me that the session is opened and closed
multiple times by the OpenSessionInViewFilter during the request.
It is normal that the session got opened and closed multiple times by the
OpenSessionInViewFilter during a request?
Does any one has an idea why this happens and how to fix this?

Re: Lazy loading exception despite of OpenSessionInViewFilter and

Posted by Jochen Mader <pf...@gmail.com>.
Open session in view is a bad idea with a full fledged ajax-Wicket
application as things get unpredictable pretty fast.

Re: Lazy loading exception despite of OpenSessionInViewFilter and
object loading within a request
Posted by "Florian B." <fl...@gmail.com>.
You're right. The redirect form the login page to the application's home page
seems to be a new request. I've simply tested it by trying to access the
user's roles directly after the user was retrieved from the database and
before the redirect to the application's home page. Here the roles could be
loaded without lazy loading exception.
So thanks for the tip!

Re: Lazy loading exception despite of OpenSessionInViewFilter and

Posted by Sven Meier <sv...@meiers.net>.
Hi,
there are multiple requests going on probably (e.g. because of redirects),
You should put a breakpoint into WicketFilter to debug the requests.

1.5: How to get Page instance from RequestCycle in IRequestCycleListener
Posted by bh...@actrix.gen.nz.
Hi,
in 1.4, I could get the last page instance with
WebRequestCycle#getResponsePage()
In 1.5, I cannot find org.apache.wicket.Page instances, only
IRequestablePage, and this indirectly via
(RenderPageRequestHandler)getActiveRequestHandler()
Any help is appreciated.
Kind Regards,
Bernard
