Re: [newbie] Wicket, Spring, Hibernate and transactions in views.
I don't think so.
I'd recommend you to make your transactional control in your services and
call them from your pages instead of trying to control it in your view.

All,
I've got a bit of a newbie Wicket question involving Spring, Hibernate
and transactions.
The question that I can't seem to find an answer to;
Can a view be a created/injected/aop'd like a spring bean so that it
honours @Transactional methods for hibernate?
An example;
public class HomePage extends WebPage {
@SpringBean // this is working fine
private SessionFactory sessionFactory;
public HomePage(final PageParameters parameters) {
this.init();
}
@Transactional // this is not working
public void init() {
Criteria criteria =
sessionFactory.getCurrentSession().createCriteria(MyEntity.class);
ListMyEntity myEntities = criteria.list();
for( MyEntity myEntity : myEntities ) {
// where subEntities is a lazy collection
for( SubEntity subEntity : myEntity.getSubEntities() )
{
// ...
}
}
}
}
I've been reading Wicket In Action book, various places on the net and
of course, emails on the subject on this list and this particular
tutorial;
http://wicketinaction.com/2009/06/wicketspringhibernate-configuration/
And I'm still wondering, is this something that is actually possible? I
could full understand that it wouldn't be - i.e. that the injector only
works for Spring injection dependency and not AOP or anything else. So
you inject your dependencies - and they have transaction support etc.
But that means I'll be having to force fetching of lazily fetched
children from outside the views themselves, which is obviously very
painful. It would be so much easier to have transaction support in the
view itself and not have to delegate.
Any help would be greatly appreciated.
The error message I'm receiving is;
Caused by: org.hibernate.HibernateException: createCriteria is not valid
without active transaction

Re: Announcing: visural-wicket 0.5 released - open source wicket components
Great Job! I was looking for a Drop Down like that. Thanks and keep the good work.

The download package includes full source + javadocs. The project page is at http://code.google.com/p/visural-wicket/ and there are live examples at http://visural-wicket-examples.appspot.com/ I've been working on this project for around 4 months and it is now a mature and pretty stable set of tools for developing Wicket apps. I'm using it in my day-to-day work in some very large applications. I'd like to get some feedback and/or collaborators on the current state of the project, and hope that other members of the wicket community may find these components and utilities useful. cheers, Rich. -- Richard Nichols :: http://www.visural.com/ :: http://www.richardnichols.net/ -- /** * Pedro Sena * Systems Architect * Sun Certified Java Programmer * Sun Certified Web Component Developer */
Re: How to store/load strings shared by many (but not all) pages?
I was thinking about this yesterday... This is a very common scenario, specially for i18n messages related to exceptions.

Doubt with Link
Hi Guys, First of all, sorry for a so newbie question, but I'm really a newbie in Wicket. I'm trying to add a Behaviou to my link, it works fine with link.add(myBehaviourHere) I'd like to know how to avoid any page redirect the link does. I left onClick without code but it redirects to the page that I'm actually(expected behavior) Any tips?

Doubt with Maven config
Hi Guys, I'm using lolite archetype but I'm having a 'problem' I want to run my tests (JUnit) and keep the Jetty server alive after the tests. Every time that I run my maven tests, it creates a Jetty server that is killed at the end of the process. I'm trying to do the same thing as Wicket in Action, I changed the Start.java that comes with lolite but it not helped. I'm sure that I'm missing some detail, I'd appreciate some help with it.
