SV: Localizer in a new Thread
To clarify, I want to use Localizer#getString(...) in a thraed I create. I have seen other posts on this issue, but haven't been able to figure out the solution. The Localizer.getString() looks for its messages in Wicket's property file structure, which depends on Application, the resource-oriented classes, hierarchies and so forth. Your best bet is to pre-read the values you need into a Properties object that you pass to the thread code. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

RE: Localizer in a new Thread
There was a long discussion about this. One of the proposal was to use
InheritableThreadLocal which would solve this problem, but there was a lot
of concerns about this approach.
The solution I have found was this:
If you create the thread with ExecutorService, you could do the following:
final ExecutorService service = new ScheduledThreadPoolExecutor(1) {
@Override
protected void beforeExecute(final Thread t, final Runnable r) {
Application.set(app);
};
@Override
protected void afterExecute(final Runnable r, final Throwable t) {
Application.unset();
}
};
and execute you thread like this:
service.submit(new Runnable() {
@Override
public void run() {
//do stuff
}
});
This will ensure that Application is accessible from within newly created
thread.

How to Update contents of a child component?
Hi All I would like to know an elegant solution to deal with the following issue. For CRUD operations this is the approach I have taken. List of Components 1.ContainerPanel 2.SearchPanel 3.SearchResultsPanel 4.DetailsPanel and this contains a child component that has a MultiSelectControl The ContainerPanel adds the SearchPanel. The SearchPanel, adds SearchResultsPanel and DetailsPanel. So when I first load/render the ContainerPanel, I hide the SearchResultsPanel and DetailsPanel. When some search is done then I make the SearchResultsPanel visible. OnClick event of an item of the SearchResultsPanel , I unhide and update the Model of the Details panel. Now,for some reason it does not seem to refresh the child component in DetailsPanel(.ie. MultiSelectControl) So on every OnClick, I want the Details panel to refresh the content of the nested component in Details Panel. At the moment, I can't see a way to do this, other than removing the nested component and re-creating it. I am sure its not the right way to do it. Has anyone had a similar scenario before? I would like to use a cleaner way to approach this. Also is this approach for CRUD acceptable as in using the container approach?

Re: How to Update contents of a child component?
Hi, Have you checked that rendered values in your components are model-driven? If so then I think it should work. I sometimes set values in the constructor with brute force when I do not expect any changes. This is not what you want in this case. I found it most helpful to exclusively use LoadableDetachableModel, remove the Serializable interface from my model objects and let SerializableChecker sort out some model problems for me. I went so far as to use a LDM in my WebSession. After some time I had sufficient practice with models that things started to become really easy.

Re: Single session per user
For that you may need to do your own session tracking using an HttpSessionListenerhttp://download-llnw.oracle.com/javaee/5/api/javax/servlet/http/HttpSessionListener.html, and trying to handle yourself a Session cache (Be carefully of not leaking those session by not preventing the container to reclaim that memory when needed if they got stale). Also i believe Spring Security (former Acegi) has builtin support for this use case.

Trouble creating a behaviour that adds JS and also a Body onLoad event
Firstly, I'm having some trouble finding a decent behaviour tutorial. If anybody knows of one post a link up. Now, the problem I am having is creating a behaviour that adds some JS to the head and sets an onLoad method. The JS project instructs users to add: body onload=jsfunctionhere ( options, callback ); but I'm not sure how Wicket supports this. Any ideas? Cheers
Re: Trouble creating a behaviour that adds JS and also a Body onLoad event
Hi!
You could try this:
public class HomePage extends WebPage implements IHeaderContributor {
@Override
public void renderHead(IHeaderResponse response) {
response.renderOnLoadJavascript(javascript)
}

RE: Localizer in a new Thread
I am not sure how to preload the the values. I am trying this, but am not getting anywhere. myApp.getResourceSettings().getPropertiesFactory().load(ScanManTask.clas s, com.scanman.cron.task) I have a properties file named ScanManTask.properties and have added it to my app like this: getResourceSettings().addStringResourceLoader(new ClassStringResourceLoader(ScanManTask.class)); ScanManTask is not a commponent. The load method has a clazz and path argument. I am assummeing the class is the class associated with the property file and the path is the package it is in? I guess I could just load them manually, but I would like to take advantage of localization.

Re: Wicket and JEE6
I have found an elegant solution to the serialization problem.
Basically, in the ComponentInstantiationListener that perform injection, I
am also attaching a new InjectionBehavior. The injection behavior has a
private transient boolean field indicating whether injections are up to
date. Upon serialization/deserialization of a component, this field is reset
to false because it is transient. As a result, I can detect in the
beforeRender() method of the behavior whether I need to do injection.
The code of the component instantiationlistener is now as follows:
@Override
public void onInstantiation(Component aComponent) {
injector.inject(aComponent);
aComponent.add(new InjectionBehavior());
}
With the InjectionBahavior defined as follows:
public class InjectionBehavior extends AbstractBehavior {
private transient boolean injectionUptodate;
public InjectionBehavior() {
injectionUptodate = true;
}
@Override
public void beforeRender(Component aComponent) {
if (!injectionUptodate) {
InjectorBuilder.getInjector().inject(aComponent);
injectionUptodate = true;
}
}
}
This solution prevents unnecessary injection. This is required because
injection is expensive. For a simple class with only one injection I
measured only 1400 injections per second (I understand the weld project is
working on improving performance at the moment).
Another part of the solution is to be able to deal with detachable models
that need to keep a reference to an entity manager. The problem is that
these detachable models are also serialized/deserialized. For this I am
using a similar trick now to create a dynamic proxy of an entity manager
that delegates to a dynamically looked up version of the entity manager. The
lookup is done by creating a dummy object with a @persistenceContet in it
and using CDI to inject/obtain the entity manager. Here similarly, the
lookup caches the entity manager as a transient reference so it knows when
to recompute the entity manager.
The object that does this lookup is in fact a managed bean with a producer
method annoted with @Produces @ApplicationDatabase and @PersistenceContext:
public class EntityManagerLookup implements Lookup {
private static class EmHolder {
@PersistenceContext
private EntityManager em;
public EntityManager getEm() {
return em;
}
}
private transient EntityManager em;
@Override
public Object lookup() throws Exception {
if (em == null) {
EmHolder holder = new EmHolder();
InjectorBuilder.getInjector().inject(holder);
em = holder.getEm();
}
return em;
}
@Produces
@ApplicationDatabase
@PersistenceContext
public EntityManager getDefaultEntityManager() {
LookupProxyFactoryEntityManager factory = new
LookupProxyFactoryEntityManager(
EntityManager.class, new EntityManagerLookup());
return factory.getProxy();
}
}
Using this method, I can inject this serialization-safe entitymanager into
any object using
@Inject @ApplicationDatabase EntityManager entityManager;
So, in fact, I have a two-part solution. First of all it is robust in the
sense that @PersistenceContext still works. Second, I can also use a custom
injection to obtain serialization safe entity managers. When the entity
manager is obtained using the custom method however, problems can still
exist with for instance application scoped objects which also appear to be
serialized (this is in fact wrong as the objects will no longer be
application scoped because several copies are created).
A consequence of this solution is that all injected dependencies should be
declared as transient because this is more efficient.
The code for this can be found at http://utils.wamblee.org (wicket/inject,
support/inject, and support/cdi).
Re: Localizer in a new Thread
Yes, the solution I've mentioned in previous post should solve your problem.
