AjaxFormValidatingBehavior with multiple FormComponents

[Jochen Mader]

Wicket 6.9.1:
I ran into a weird issue:
I am trying to submit a form when pressing enter. Using
the AjaxFormValidatingBehavior (same for AjaxFormSubmitBehavior) I can
submit a form with a SINGLE FormComponent.
When adding a second one the form won't submit when pressing enter.

Sourcecode below shows what I am doing. Removing the DateTextField makes
the whole thing work:


Form form = new Form("taskForm", new
CompoundPropertyModel(new Task())) {
@Override
protected void onSubmit() {
taskListModel.getObject().addTask(getModelObject());
setModelObject(new Task());
send(getPage(), Broadcast.EXACT, new TaskCreatedEvent());
}
};


add(new
FeedbackPanel(FEEDBACK).setOutputMarkupPlaceholderTag(true).setOutputMarkupId(true));
add(form
.add(new TextField("title").setRequired(true))
.add(new DateTextField("dueDate").add(new DatePicker()))
.add(new Button("submit").add(hideIf(javascriptEnabled(
);
add(new AjaxFormValidatingBehavior(form, "onsubmit"));

Re: using static fileds in a page

[Jochen Mader]

If you are already using Spring why do you need the field to be static?
Beans are by default singleton scoped and can be tailored to
session/request scoped.

Re: Eclipse or IntelliJ

[Jochen Mader]

Well, weighting a few years of Eclipse usage vs one week of Idea is
not really a fair comparison.
It took me about 4 months to really get into Idea (short-cuts,
different compile behavior ...).
If you ever really consider switching an IDE don't base your
assumptions on a week of usage.
If there weren't any differences we wouldn't have several major IDEs.

But that's just my two cents ;)

P.S.: Netbeans is also an awesome IDE, it just gets horribly slow with
bigger projects (and that's based on the most recent Release of
Netbeans I tried a week ago).

Re: Eclipse or IntelliJ

[Jochen Mader]

I don't really like forcing people to use a specific IDE. We keep our
stuff IDE-agnostic as far as possible.
That said:
I have about 50 lines of code in my current multimodule project in Idea 12.
No slow down or any other problems ;)
But I have to say: Idea 10 was a horrible failure.

Re: Eclipse or IntelliJ

[Jochen Mader]

I abandoned Eclipse for IntelliJ after using it for almost 10 years
because of Maven. Since then I have become a big Idea-Fan :)
Working with Wicket using the community edition (the free one) is no
problem at all as you can use the Maven-Jetty-PlugIn. I did that for
quite a while.
I only switched to Ultimate because I have to work with several
app-servers (JBoss, TomcatEE, Glassfish,...).

Re: ASK: Updating one wicket page's component from other wicket apps

[Jochen Mader]

I would say he already provided all workable options:
1. Use a dedicated messaging mechanism (JMS) through a container
(Spring, JEE6, ...)
2. Build your own messaging mechanism

Which one is best for you depends on your requirements.

Re: update panels inside webmarkupcontainer

[Jochen Mader]

As long as you are not holding references on your own it will be
collected after a replaceWith.

On deleting pages: You could use DefaultPageStore.removePage but I am
not sure if that's a really good idea. Wicket is pretty good in
managing what's in the store and you should rely on its behavior as
much as possible.

Re: Constructors take vararg of Component? (Enhancement RFC)

[Jochen Mader]

Why aren't you using fluent interfaces?
The API ist built around that and allows for a much cleaner structure
inside your constructors.
Just watch out for those Auto-Formaters ;)

new Form("frmRsvp", cpm)
.add(new StatusPanel("pnlRsvp"))
.add(new ConfirmPanel("pnlConfirm"))
.add(new RsvpRulesPanel("pnlRsvpRules"));

Re: JPA annotations

[Jochen Mader]

I think you should first understand what the different JPA-annotations
actually do.
@Entity, @Table, @Id, @GeneratedValue are annotations used on the
entity level to tell the mapper what to do with properties. These
informations are of no interest to Wicket.
@EJB, @PersistenceUnit, @Resource are annotations used for isntances
injectable by an appropriate container (which can bee CDI, Guice
Spring, ...).

Re: Why is SortParam.getProperty generic?

I was just about to answer my own question.
We migrated a big part of our application to use LambdaJ instead of
PropertyModels. With getProperty being generic it's now possible to
use it instead of passing around strings.

Why is SortParam.getProperty generic?

[Jochen Mader]

It might be due to the fact that I am sick but I don't get why
SortParam.getProperty doesn't return a String but T.
So far I always used getProperty as vasis for a PropertyModel to resolve things.
Any hint would be appreciated,

Re: Thread safety of various Wicket classes?

[Jochen Mader]

First of all:
You shouldn't start optimizing without having an actual problem.
I don't see a real benefit in sharing a validator between several components.

ON THE OTHER SIDE

There shouldn't be a problem using Validators across several component
instances as I am not aware of a single stateful validator.
No state = threadsafe (wack me on the head if I'm wrong)

 I currently use

Re: Wicket 6 and CDI

[Jochen Mader]

Hehehehe, that was easy :)
It's just a couple of package-renames and fixing the
ConversationExpiryChecker to use the new way of getting the
AjaxRequestTarget:
AjaxRequestTarget target = RequestCycle.get().find(AjaxRequestTarget.class);
if (component instanceof Page ||target != null)
Took me like 3 minutes.
I just did a quick smoke test in Glassfish and so far things are looking good.
Will hopefully get some more time tomorrow evening to test a little more.
If I find any problems I will let you know.

CU,

Jochen

Re: Wicket 6 and CDI

Tried it out a few minutes ago.
Looks a few things got moved into the core package (e.g. IPageRequestHandler).
I had a quick look and so far I didn't find anything beyond renamed
packages (but that's just a few minutes of looking).
I might just give it a shot and try to get it running.

To get that out of the way: I know that Wicket 6 won't be shipped with

I still would like to use Wicket 6 in Glassfish.
Are there plans to port wicket-cdi to Wicket 6? I couldn't find

New book on Wicket 1.5

[Jochen Mader]

Hey,
Sorry for spamming I couldn't figure out who to contact to (hopefully)
get this listet in your books section:

a few weeks ago my book on Wicket 1.5 got released:
http://www.amazon.de/Wicket-Komponentenbasiert-objektorientiert-alternative-Java-Webframework/dp/3868020810

It's written in German and has been published by Entwickler Press.


Titel   Wicket: Komponentenbasiert und objektorientiert- das alternative
Java-Webframework
Autor   Jochen Mader
Verlag  Software + Support, 2012
ISBN3868020810, 9783868020816
Länge   219 Seiten

Kurzinfo
Apache Wicket ist ein komponentbasiertes Webframework, das sich in den
letzten Jahren zu einem der beliebtesten Vertreter seiner Gattung
gemausert hat. Man könnte diese Beliebtheit mit der einfachen
Integration von Ajax oder der rigorosen Trennung von Markup und Logik
erklären. Aber was Wicket wirklich über die Masse konkurrierender
Frameworks erhebt, sind der Verzicht auf eine eigene Markup-Sprache
und das objektorientierte Programmiermodell. Dadurch rücken Java und
seine Sprachmittel stark in den Vordergrund. Das ermöglicht es
erfahrenen Entwicklern, sehr schnell in die Kernkonzepte von Wicket
einzusteigen und auch komplexeste Anwendungen umzusetzen.

Ziel dieses Buchs ist es, die grundlegenden Konzepte von Wicket zu
vermitteln und im weiteren Verlauf auf fortgeschrittene Aspekte
einzugehen. Hierzu wird eine Beispielanwendung entwickelt und Schritt
für Schritt erweitert. Anhand detaillierte Codebeispiele werden
Sachverhalte wie der Wicket Request Cycle, Models, Validierung und
JUnit Testing erklärt. Des Weiteren werden Themen wie
Deplyoment-Szenarien (JEE6, Spring, ...) , jQuery-Integration und
Performance-Tuning in separaten Kapiteln behandelt. Durch Studium
dieses Buchs soll ein Entwickler befähigt werden, skalierbare,
wartbare Webanwendungen in Wicket zu bauen, und er soll lernen,
eigene, wiederverwendbare Komponenten zu entwickeln und fremde
Komponenten zu erweitern.
Zielgruppe
Entwickler mit soliden Java-Kenntnissen und einem Grundverständnis der
wichtigen Webtechnologien wie HTML und CSS
Der Autor
Jochen Mader hat über zehn Jahre Erfahrung  im Bereich Architektur und
Entwicklung. Derzeit ist er bei der Senacor Technologies AG für
verschiedene Wicket-Projekte als Technical Lead verantwortlich.


Thanks,

Jochen

Modifying PageParameters

[Jochen Mader]

Hello,
I am currently working on a Weld-Integration for Wicket 1.5.
Got almost everything done but Conversations are giving me a headache.
When navigating to another page I need to provide the conversation ID.
Only at the very end of a request I am able to figure out if the
conversation is valid.
For an AjaxLink using setResponsePage I thought the following would be
the thing to do:
Use onRequestHandlerExecuted to do the stuff at the end of the request.
There I look for an IPageRequestHandler and modify its PageParameters
using one of the following methods:
pageHandler.getPage().getPageParameters().add(WeldMetaData.CONVERSATIONID,
conversation.getId());
pageHandler.getPageParameters().add(WeldMetaData.CONVERSATIONID,
conversation.getId());

Apparently this doesn't work and parameters set in this way won't end
up in the response page.
What do I have to do to achieve this?

Thanks,

Jochen

Re: Problem with IMarkupResourceStreamProvider

Problem with IMarkupResourceStreamProvider

[Jochen Mader]

I implemented a panel as a IMarkupResourceStreamProvider.
It works perfect if I add it to a page using the add method. If I use
"replaceWith" to replace another panel with this one I get

"Tag expected"

and the following stacktrace

 MarkupStream: [markup =
org.apache.wicket.util.resource.StringResourceStream@19aea6e2:
http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";>
   
   
  
http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";>
   
   
  , index = 0, current = [Raw markup]]
at 
org.apache.wicket.markup.MarkupStream.throwMarkupException(MarkupStream.java:526)
at org.apache.wicket.markup.MarkupStream.getTag(MarkupStream.java:258)


Original Markup:
http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";>









I create a StringResourceStream using the markup stored in a String:

new StringResourceStream(ret);

Any idea?

Re: Statful image

[Jochen Mader]

Uh, sorry :)
It all comes doen to the handling of shared and-nonshared resources.
If a resource is non-shared (read: not registered with
sharedresources). If the Image resource is null it can't assume that
it's shared, therefore handling is at a non-shared/stateful resource.

We just stumbled upon the following code in the Wicket(1.4.17) Image
class getStatelessHint method:
return (getImageResource() == null || getImageResource() ==
localizedImageResource.getResource()) &&
localizedImageResource.isStateless)

My question is:
Why does an image become stateful because of a missing reference?

Got some code for you (ObjectSizeOfAgent)

[Jochen Mader]

Hey,
a while ago I wrote about the difficulties to get the ObjectSizeOfAgent to run.
As I needed it pretty badly for a project I built something new and
added some more accurate size measurement for objects.
I put all my code on Github and I am going to add some more
performance related things in  there.
https://github.com/pflanzenmoerder/object-size/

I copied the code from the size of agent (with proper mentioning of
where I got it from) and added it as one of the possible strategies to
estimate the size of pages in ram.
It all uses AspectJ and has no direct dependencies to Wicket and can
be deploied as an agent using LoadTimeWeaving.
It's all Appache 2 License (I hope that's correct).

Would that be of any interest for the Wicket-project?

Usage of ObjectSizeOfAgent

[Jochen Mader]

I am trying to get the ObjectSizeOfAgent to run in Tomcat.
So far I had no look as it has quite a lot external dependencies.
has anybody got this to run or got some pointers what to do?

What I did so far:
added the javaagent to the commandline and it gets loaded.
I had to put all libs required by the agent into the endorsed dir
(wicket, agentlib, slf4j related stuff) so it can start.
It is starting up but as soon as it tries to start my webapplication
it gives me a ClassNotFoundException when loading javax/servletFilter.


The servlet-api is in the lub directory and there is no other copy of
it in the war or in endorsed.

Wicket archetype for hibernate 3.5 and spring 3

[Jochen Mader]

I created a Maven archetype for wicket application containing the
following things:

- Everything is configured using Spring 3
- Hibernate 3.5 is used for persistence
- Example classes using JPA-style annotations
- Example DAOs and base classes for CRUD-operations
- Everything runs on an InRam-HSQL

I will add some better unit tests this week.
I added the Apache License so it should be compatible with Wicket.
It is somewhat based on the original Wicket-Archetype. I hope I did
everything right and didn't break any licenses.

Grab your copy from:

Re: Speeding Up HTML Parse???

[Jochen Mader]

a) Read the speed tracer output, if the time is spent with the redirect or
loading the actual markup it will tell you.
b) HTML rendering in the browser is influenced by the markup and ajax. Read
the speed tracer output and it will tell you where the time is spent. It's
most likely not wicket that costs the initial 30 second delay but some
resource taking long to load, an AJAX component doing its magic ...
But that's all client(browser)-side stuff.

Re: Wicket, Spring 3 and UnitTesting

[Jochen Mader]

Oh man, you are right.
My eyes got a little selective on that line :)

Re: Wicket, Spring 3 and UnitTesting

[Jochen Mader]

Sorry for my late answer.
StaticWebApplicationContext doesn't cut it for  me.
Your example contains a small mistake:
Inserting the mock-object won't work as registerSingleton expects to get a
Class.
As I want to create mock objects with EasyMock there are two approaches (as
far as I know).
The one I have shown before, involving the creation of the custom
ApplicationContextMock or using easy mock inside a testing-spring.xml.

Re: wicket osgi (not Pax)

[Jochen Mader]

I ran into a lot of use-cases for it.
Just take a look at esper and drools. They are packaged as OSGi and need to
be able to work with classes provided by people using them.
But yes, we are getting a little off topic here :D

Re: wicket osgi (not Pax)

[Jochen Mader]

Buddy-class loading is real OSGi since 4.1 ;)
The new MANIFEST.MF entry is named "Bundle- *BuddyPolicy".*

Cheers,

Jochen

Wicket, Spring 3 and UnitTesting

[Jochen Mader]

Just figured out how to do UnitTesting with Spring 3 and Wicket.
Spring 3 introduced a check to see if a given context was a
WebApplicationContext. That means ApplicationContextMock is not suitable for
testing (giving the infamous " No WebApplicationContext found: no
ContextLoaderListener registered?" message).
I simply extended the class and added WebApplicationContext interface.

The following example shows how to get it going (I hope the code doesn't get
messed up):


public class TestHomePage extends TestCase {

private WicketTester tester;


 @Override

public void setUp() {

final WebApplicationContextMock appctx = new WebApplicationContextMock();


 final ServiceOfDoom mock = createMock(ServiceOfDoom.class);

expect(mock.getIt()).andReturn("whups").anyTimes();

replay(mock);

 tester = new WicketTester(new WicketApplication()) {

@Override

public ServletContext newServletContext(String path) {

MockServletContext servletContext = (MockServletContext) super

.newServletContext(path);

appctx.setServletContext(servletContext);

appctx.putBean("scratchy", mock);

servletContext

.setAttribute(

WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,

appctx);

return servletContext;

}

};

tester.getApplication().addComponentInstantiationListener(

new SpringComponentInjector(tester.getApplication(), appctx,

false));

}


 public void testRenderMyPage() {

// start and render the test page

tester.startPage(HomePage.class);


 // assert rendered page class

tester.assertRenderedPage(HomePage.class);


 // assert rendered label component

tester

.assertLabel("message",

"whups");

}


 private class WebApplicationContextMock extends ApplicationContextMock

implements WebApplicationContext {

private ServletContext servletContext;


 public  T getBean(Class requiredType) throws BeansException {

// TODO Auto-generated method stub

return null;

}


 public  A findAnnotationOnBean(String beanName,

Class annotationType) {

// TODO Auto-generated method stub

return null;

}


 public Map getBeansWithAnnotation(

Class annotationType)

throws BeansException {

// TODO Auto-generated method stub

return null;

}


 public void setServletContext(ServletContext servletContext) {

this.servletContext = servletContext;

}


 public ServletContext getServletContext() {

return null;

}


 }

}

Re: JSR 330 Spring

[Jochen Mader]

Thanks for the quick answer.
I never came across a scenario where somebody did or I would use two IoC
containers in the same application.
Why would you do that?

JSR 330 Spring

[Jochen Mader]

Hello,
I am using wicket together with spring. Getting it going with @SpringBean
was pretty straight forward but now I am wondering if it is possible to get
it going with JSR 330 annotations as the spring side of my app is already
using it.

Thanks,

Jochen
