Re: Type Inference for Wicket 1.4
I can sympathise with that. However I don't think it would be a
maintenance nightmare if the constructors are set to private; but that
would mean a dramatic API change for such convenience and I'm guessing
you're not willing to do this.
Best,
James.

[wicket] Load Testing Wicket Applications
Today I looked for a programmatic way to load test a Wicket application and there doesn't appear to be any tools at present to do so.

I was thinking of an API that specifies the a test suite contain individual load tests, which contain the amount of threads to create and the target components to test.

Re: Wicket + Hibernate without Spring for lazy loading
Well you can use your business logic objects inside Wicket but you have to ensure that you you hold one, and only one, instance for each business object (assuming these objects are stateless) and that you do not accidentally serialize these objects and their dependencies within your Wicket pages. If you don't want to use Spring, have a look at Google Guice - which is a very simple, elegant yet powerful DI framework. Wicket provides support for Guice so you don't have to worry about accidental serialization. Once you have got to grips with Wicket and Guice then you can get really creative to enable Guice to inject Wicket components in your Wicket application. Cheers, James.

Re: [OT] Book/pointers on caching
Caching wicket components is a really bad idea as you will run into concurrency issues. IMHO the caching strategy depends on the how immutable the data is, its transaction isolation (read-only, read-write, etc) and what performance problem you are encountering (Cartesian product, N+1 select, etc). Have a look at the Java Persistence with Hibernate for a primer on the subject. Cheers, James.

I understand that I need some caching mechanism. And as many have pointed out on this list, it is preferable to not do this in the presentation layer (caching Wicket components) but to move the caching to the business logic or persistence layer. So my Wicket models still make the same calls, like service.find(blabla), but behind the scenes, a cache speeds up the access. The question is just: what are good caching strategies? When to update the cache? Should the cache itself know when to invalidate entries? Etc. Is there any sample code, articles, or books on this that you can recommend?

Re: @SpringBean vs getApplication().getDao()
As far as I am aware, the main internal differential is that annotations provides a quick, safe way to access your spring beans and ensure that the whole container does not get serialized via a proxy. However the magic comes at a cost that it will serial the bean id (as a string) - which can be costly if used a lot in your components. On the other side of the coin, using the other option does not have any serialization cost but its very vulnerable to accidentally serializing the bean and, potentially, the whole application context. Personally I use the latter option where I access my service facade bean by a static import. I prefer this route as I am paranoid about memory usage but each their own. Best, James.

I'm using JCR, and have a RepositoryDao bean configured in applicationContext.xml. RepositoryDao has a template property which points to an instance of JcrTemplate in applicationContext.xml, all repository access is performed through that template. I have an AccessPage which has a RepositoryDao injected via @SpringBean. There is an inner class Form on that page, it has a default submit button and three submit buttons that skip default processing and perform their own operations onSubmit(). Both default button and skip-default-processing buttons use the same repositoryDao property of AccessPage to perform certain operations on repository. I noticed that when I actually open that AccessPage, there's a new RepositoryDao object created, and it's template property is null. When I press any of those non-default submit buttons of the form, everything works fine. But on default button onSubmit(), I see that there's yet another insance of RepositoryDao created, and it's template is also null, which leads to NullPointerException. I assumed that beans configured in applicationContext.xml are actually singletons, so there won't be any new instances of such nodes upon pages-with-injections instantiation. Regardless of whether that assumption is correct/incorrect/my-god-rtfm, I still won't understand why default submit button reaction is NPE as it uses same partnershipDao property of AccessPage. Could someone please elaborate some internal differences of the annotation-based approach as opposed to storing DAOs in Application object. In the latter case it's quite clear that there's a single instance of RepositoryDao as a property of MyApplication which is pulled on ((MyApplication) Application.get()).getRepositoryDao().

Re: When to pass object instance /class type?
That is incorrect. You can pass data to your CoolPage regardless of the setResponsePage() method signature. Just try implementing both and observe the URL once you invoke both its signatures. One will be bookmarkable and the other will not be but I'll leave it to you which signature is bookmarkable. Once you have explored this, investigate PageParameters, WebApplication's mountBookmarkablePage method then URL Coding strategies. Oh, make sure you have either a default constructor or a constructor passing in a PageParameters in your CoolPage before playing around with the setResponsePage(Class pageClass) signature. ;-) Best, James.

Re: Wicket + spring + jpa/ hibernate = lazy load exception
Firstly, your code is rather strange. That getFoos() method is not part of
the List Interface API.
Two possible solutions:
The filter chain maybe incorrect in your web.xml. Your
OpenEntityManagerInViewFilter might not be preceding the Wicket filter.
Check that it does precede it.
If you have a deadline then I recommend having one query that retrieving
both foos and bars in one hit. I've never touched JPQL but in Hibernate
Query Language (HQL), one could write this:
select f from Foo f inner join fetch f.boo b where b.id = :id
Good luck,
James.

I am experiencing exactly the problem outlined in the subject of this post,

It's the first time I'm using Wicket with JPA, and I just don't understand
why this isn't working.
I have a Wicket dataprovider that looks like this (I've simplified it a
bit):
public abstract class FooDataProvider extends SortableDataProvider
{
private static final long serialVersionUID = 1L;
@SpringBean
protected MyAPI myApi;
public FooDataProvider()
{
super();
// Injects the spring bean
InjectorHolder.getInjector().inject(this);
}
public Iterator iterator(final int first, final int count)
{
ListBar bars = myApi.getBars();
ListFoo foos = bars.getFoos();
return foos.iterator();
}
}
I am using a very standard Spring JPA setup, and my web.xml includes a
OpenEntityManagerInViewFilter. The spring bean is being injected properly,
and my list of Bar is returned correctly. But I get a
LazyInitializationException no matter what I try. What am I doing wrong?
Many thanks,
Julian

Re: GetModelObject returns null-filled Object?
What model are you using for the form? How are you setting it?
While you're there have a look at IFormValidator (look at its
implementations to see how to use it) as it's much neater to add your
Hibernate validator like this rather then hard coding it in your
overridden onSubmit method.
Best,

When I use the debugger and look at foo, every variable is filled with null,

Why is this the way it is? Can I change it?
Because Hibernate Validator also can´t read out the correct content and says

Re: application scope objects in Wicket
Firstly I hope you are enjoying building your first Wicket web app.
Is this application scope object immutable? What is the data structure?
IMHO, if it's immutable then it's OK to use composition within your
WebApplication by adding this object as a field within WebApplication.
I would just make it final so it never gets incorrectly pointed to a
different object once initialized.
However if this has mutable shared data, then do not use the
WebApplication's intrinsic lock as you will jeopardize its throughput
to process requests. For example:
public class FooBarApplication extends WebApplication {
private MyAppScopeObject appScopeObject;
public synchronized MyAppScopeObject getAppScopeObject(){
return appScopeObject;
}
public synchronized void setAppScopeObject(MyAppScopeObject appScopeObject) {
this.appScopeObject = appScopeObject;
}
}
Instead, use your application-scope object's intrinsic lock or use a
suitable mutex in the Java 5/6 API.
Best,
James.

Hi all, I'm new to Wicket and developing my first Wicket website.
I have some temporary objects created inside a users' session but needed by
a parallel process which uses them

I'm looking at using application scope objects but I'm not sure how to do it
best
in Wicket.
I guess I should override the get() method of WebApplication
mimicking the pattern used for custom Session objects.
public class WicketApplication extends MyWebApplication
{
private Object applicationScopeObject;
public WicketApplication() {
setApplicationScopeObject( init value );
}
@Override
public static WicketApplication get() {
return (WicketApplication) WebApplication.get();
}
public Object getApplicationScopeObject(){
return this.applicationScopeObject;
}
public void setApplicationScopeObject( Object applicationScopeObject ){
this.applicationScopeObject = applicationScopeObject;
}
[...]
}
public class PageInsideUserSession
{
public PageInsideUserSession(){
[...]
// object has already been initialized
WicketApplication.get().setApplicationScopeObject( object );
}
}
public class PageOutsideUserSession
{
public PageOutsideUserSession(){
Object object = WicketApplication.get().getApplicationScopeObject();
[...]
}
}
In my case synchronizing the access to the application scope object should
not be needed.
Is this approach correct (and efficient) or is there a better solution ?
Should I maybe use a separate parent class (parent of WicketApplication and
child of WebApplication) for
overriding the get() method (in case the override interferes with something
else in the framework) ?

I use Spring/Hibernate as my stack and I find it fits perfectly with Wicket and my domain models. I personally think Spring offers rich transaction management with its transaction managers, DAO template classes and generic DAO exception hierarchy. I don't have any experience with Spring or Java EE or EJB, but have been avoiding Spring because of what I have read and seen online with so much XML-coding. Is it possible to use spring transaction module by itself and without too much XML? I'd really appreciate hearing what y'all are you guys using for your transactional needs. As of Spring 2.5, you can configure your beans with non-evasive, fine grained annotations. It's declarative transaction model is now annotation based (as of Spring 2.0) so you can make your methods transactional using the @Transactional annotation and it can even be declared on an interface. The propagation and isolation can also fine tuned like: @Transactional(propagation=Propagation.NOT_SUPPORTED, readOnly=false) void updateOrderLineQuantities(ListOrderLine orderLines); Read this chapter to understand how Spring does transaction management: http://static.springframework.org/spring/docs/2.5.x/reference/transaction.html Best, James.

Re: Transactions won´t work?
How are you configuring Spring within Wicket? Correct me if I'm wrong but the transactional weaving that you are trying to advise will only work if Spring can see them in its object factory (i.e. constructed within spring) - which I suspect is the case. Perhaps having spring managed service beans and proxy those in wicket using the @SpringBean annotations. Cheers, JP.

Re: Wicket + Spring 2.5
For an example app for Spring 2.5, download the full distrubution jar with dependencies; which contains ample sample apps. To understand how Wicket and Spring can be integrated and its implications, go to: http://cwiki.apache.org/WICKET/spring.html. As for a wicket app that uses Spring: http://wicketstuff.org/confluence/display/STUFFWIKI/wicket-phonebook/. However, I would recommend injecting service beans rather than your DAOs Good luck, JP.

Re: Getting started
Bonjour Gervais,
To help you understand the fundamentals of Wicket, I would strongly
recommend reading the first few chapters of Wicket in Action. It's
available for the Manning Early Access Program.
To answer your third qestion on how to bind more then one domain model
to a form, I would recommend using the Data Transfer Object which has
associations to the domain models you are binding. Then use a
CompoundPropertyModel
to access the associatios.
For example, if you are wanting to bind both Foo and Bar to a form,
you would do it like this
public class FooBarDTO implements Serializable {
private static final long serialVersionUID = 1L;
private Foo foo;
private Bar bar;
}
And the inner class form would look like this:
private final class FooBarForm extends Form {
public FooBarForm(String id, FooBarDTO fooBarDTO) {
super(id, new CompoundPropertyModel(foorBarDTO));
add(new RequiredTextField(foo.name));
add(new RequiredTextField(bar.name);
}
@Override
protected void onSubmit() {
FooBarDTO fooBarDTO = (FooBarDTO) this.getModelObject();
}
}
If it's a big form then I would recommend using a Wizard.
Cheers,
James.
3° In a big form ( with more than 20 fields ) that represnet more than
one Pojo Bean how must i work ?
Thanks

Repeater View with an empty List
Hello fellow Wicket users, If I have a FooDataProvider going to a DataView which provides a ListFoo. How do I get the DataView to display default markup, for example: trtd colspan=2There are no Foos fool!/td/tr, if this list is empty. At the moment, my table is empty and I want to give indication that there are no Foos. I am asking as I have convinced my boss to re-write our SilverStream legacy information system using Wicket.

How to enable AJAX in a Wicket application
I am wanting to use AJAX for my Wicket application but I could not find any reference documentation on how to configure it. I looked at the examples and it appears that you need to add the following to the application's init() method: getRequestCycleSettings().addResponseFilter(new AjaxServerAndClientTimeFilter()); Is this correct?

Re: Strange behavior with DropDownChoice and PropertyModel

Re: Strange behavior with DropDownChoice and PropertyModel
I would also recommend using CompoundPropertyModel rather than using lots of PropertyModels; it will save you a lot of time and code. J.

Re: Question about Guice integration with Wicket 1.3 beta 4
Hello Peter, Out of interest why did you migrate from a Spring/Hibernate design to Guice? Cheers, James. On Nov 9, 2007 5:03 PM, pmularien [EMAIL PROTECTED] wrote: Hi Wicket folks, I've just spent some time converting a Wicket 1.2.6 / Spring 2.0 / Hibernate 3 project that we did to Wicket 1.3 beta 4 / Warp (bleeding edge ;) / Guice 1.0. I am happy to report it went very smoothly. I actually had a question on the class hierarchy for wicket-ioc and how it relates (or doesn't) to wicket-guice. Was there a conscious design decision to not use the org.apache.wicket.injection.web.InjectorHolder class (and, by association, have the wicket-guice stuff inherit from ConfigurableInjector)? It would be pretty convenient if the GuiceComponentInjector worked similarly to the SpringComponentInjector and stuffed away a reference to the Guice injector - for easy access throughout the application, and also for easier mock testing. Just curious - thanks for all the hard work :) Peter Mularien -- View this message in context: http://www.nabble.com/Question-about-Guice-integration-with-Wicket-1.3-beta-4-tf4778901.html#a13671046 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Problem with selecting default value with DropDownChoice
I have a problem with the DropDownChoice. More specifically, I have a
Product class which is like:
public class Product implements Serializable {
private static final long serialVersionUID = 1L;
private Manufacturer manufacturer;
//other states
//getters and setters
}
I have a form which allows to edit a product, which allows to change the
manufacturer object with a DropDownChoice. However, an Xbox product for
instance, it should display its Microsoft manufacturer object as selected
but it selects 'Choose One' instead. Also, the setRequired for the
DropDownChoice does not work as it allows users to select 'Choose One'. I
notice it works with primitive types but not with my compositional objects.
Here is my EditProductPage:
package net.sourceforge.springcart.wicket.pages.admin;
public class EditProductPage extends AdminPage {
private static final long serialVersionUID = 1L;
@SpringBean(name = adminService)
private AdminService adminService;
public EditProductPage() {
this(new Product());
}
public EditProductPage(Product product) {
MenuBorder border = new MenuBorder(libBorder);
border.add(new EditProductForm(productForm, product));
add(border);
}
private final class EditProductForm extends Form {
public EditProductForm(String id, Product product) {
super(id, new CompoundPropertyModel(product));
add(new RequiredTextField(name));
add(new RequiredTextArea(description));
add(new RequiredTextField(sellValue, BigDecimal.class));
add(new RequiredTextField(units, Long.class));
add(new CheckBox(onSell).setRequired(true));
add(new DropDownChoice(category, catalogService.getCategories
())
.setRequired(true));
add(new DropDownChoice(manufacturer, catalogService
.getManufacturers()).setRequired(true));
}
@Override
protected void onSubmit() {
Product product = (Product) getModelObject();
product.setEntryDate(new Timestamp(System.currentTimeMillis()));
adminService.updateProduct(product);
setResponsePage(ViewProductsPage.class);
}
}
}
Any advice please?
Cheers,
James.
Re: Problem with selecting default value with DropDownChoice
Hello all,
Thanks for the replies so far.
Well I have taken the feedback and my manufacturer object and category
object are certainly are there when it passed to my form.
It is really bizarre as if I select a manufactuer and persist the product
obejct upon the form's onSubmit, it's correctly persisted. So I don't
understand why it can correctly set the manufacturer object when changing a
manufacturer yet it doesn't select the correct manufacturer upon going to
EditProductPage.
Any thoughts? I tried it with a RadioChoice and it has the same problem. :-(

Hi James,
While the implementation's not a big deal, and you'll probably want
one, Choose One is the default for when the selected (or
pre-selected) item's not found in the DDC list of values, so I don't
think it's directly that. I'd be tempted to double-check (either via
logging or via a debugger) that all the data's there as expected
(although an anonymous implementation of a IChoiceRender's as good a
way as any of having somewhere to set a breakpoint!)

Re: Problem with selecting default value with DropDownChoice
Some notes I have observed.
* All my objects within the list are correctly in the DDC
* All my objects within the list have an implemented equals/hashcode.
* It doesn't correctly pre-select both my Manufacturer associations within
Product; it just goes to 'Choose One'
* It correctly sets Manufacturer if we change the pre-selected 'Choose One'
to any object within the DDC.
So why is it not correctly pre-selecting? For example, my Xbox is not
pre-selecting to Microsoft instead going to 'Choose One'.
Cheers,
James.

Best practises and advice for integrating Wicket with Spring
Dear Wicket community, What are the best practises and advice for integrating Wicket with Spring. I have read the Wiki so I'm aware of injecting Spring's beans using annotations. I am also interested to know if I should just keep an Spring ApplicationContext in Wicket's Application class, inject the proxy-based Service POJOs into the Application or just inject them into each component that needs to use my service's methods? Look forward to your advice, James.
