Re: Apache Wicket is a Flawed Framework
@Alex Objelean Igor Vanyberg-2 Yea, my bad on just posting something up here without looking at any previous posts. Look, it was my rant and how I felt about things at the time. Nothing personal. This was actually the clean version for public consumption. It was probably still too rude though. Sorry about that. I suppose it would be lame to spend a lot of time on a framework and then have some kid post up a “Wicket Sucks” post. If you want to blow off steam and tell people you think X sucks, that's fine, but do it on a blog or something. It's just bad style to do this on a list that is meant to help out with X. If at all, the developer list would be better, but even then, you may want to consider having a chat with some of the developers first to see what their reasons for some of the things you dislike may be. Anyway, constructive criticism is good on a list like that, but I didn't get much of the constructiveness... @Jonathan Locke I agree that Java is fast. I don't worry about scaling and performance because of that. To the people worrying about memory, I don't think that is a big deal. Sure any framework is going to waste more memory than bare bones JSP/Servlets, but memory is cheap. Eclipse is like the biggest hog ever and look at how successful it is. Also, I am sticking with Java. I have a really good job and such. The only reason I would ever move is if I could land a leet job in the Valley doing Python at some sweet start-up. Not likely though. Do you live in the Bay Area? Seems to me there's plenty of work for folks wanting to do coding in other languages than Java, particularly for startups. Java is better than some of the alternatives out there: http://harmful.cat-v.org/software/ruby/rails/is-a-ghetto. Scala is still too unstable. The other Java web-frameworks are all flawed too. I don't hate my job either. Any choice will have it's own disadvantages. Also depends on what you use a language for. I'm not sold on Scala, but I wouldn't think it's not stable enough for production. May have to be careful doing upgrades maybe. @sthomps LOL! You know Eleco Hilenius wrote the “Wicket in Action” book? For some reason I can't stop laughing. Now everyone is going to think you are a badass at work. The book is decent, but it would be nice if the next edition would have a chapter at the end that rewrites the “Cheese Store” into “Cheese Store 2.0,” using all the advanced stuff that was explained in the latter chapters. It would help Wicket newcomers like me. It would also show how to do a real app with best-practices. Well, I can tell you that I hated every minute of writing it :-) One of these things one can do to 'just have done once in a life' and I'm happy to hear from people that were helped by it, and hope it helped the framework reach a certain stage of 'maturity', but never again will I write tech book in my life. Anyway, I always thought and still think that a good set of examples and test cases are often more valuable to a project. Imho the first chapter of Wicket In Action is the most important one, as it goes into the why and rough outline of how. After that, I think you should hit the examples and dig through the code. That at least works best for me... then again, I'm very much an autodidact kind of guy and respect that this is not the best way for everyone. Now, since I'm typing anyway, here are my 2c on your points: * Violates Dry - It does a bit, but I believe for a reasonable purpose. We've explored several alternatives at some point, but felt this was the least of evils * Not previewable - Hah, this one is funny... point by point; - First, we don't have seperate designers at my company - so... who's fault is that? - Second, it is better if the samer person - ah, so you think that 1 is a good idea. Well, I - as I'm sure most people who've worked on projects with some scale will agree with - disagree with you on that. Unless you are a fantastic UX persons. But most likely (just statistics, sorry) as you're posting to a programming list, you're not does development and design. - Third, if you use extends your page will not be priviewable... - Yep. So if you use it, you lose that benefit. You could not use it, or just suck it up and still be happy with the other benefits that a good separation of concerns give you. * Violates MVC - Who cares about MVC purity. It hasn't been 'pure' since the original article. Funny you mention Spring MVC, as I think that having special constructs for 'flow' is just very silly unless maybe you are writing a business process engine. * Excessively verbose and complicated - Verbosity is often there to make it easier to understand what something is/ might do. I'm sure we don't always succeed in that. Complicated is something that Wicket is also. We've been trying to find the right balance between that and power. Some things worked out better than others. * Breaks POJOS - every frameworks comes with

I didn't have a look one the wicket books for quite while. Good you told us. I orderered yours yesterday on Amazon. :) 2011/11/18 Igor Vaynberg igor.vaynb...@gmail.com * there are three books written about wicket: two for beginners and one for intermediate-advanced users. * there is a searchable mailing list archive that spans years upon years of users asking questions and getting answers. * there is a wiki that lists examples and has some good articles. * there is stack overflow questions and answers. is there an answer to every single possible question out there? of course not. no framework has that. look at projects like spring and hibernate. do those have great documentation? i bet you would say yes. are their mailing lists any less busy than our own? no. so what does that say? if i had to make up a number i would say that armed with the resources i listed you would be able to answer about 80% of your own questions. and i think that is a pretty good number. there is a very active user list to help you answer questions you cant answer yourself, usually faster then a commercial support contract. for free. not too shabby. -igor On Thu, Nov 17, 2011 at 3:30 PM, Gaetan Zoritchak g.zoritc...@moncoachfinance.com wrote: I must admit that I agree with you.

AJAX update and file download on Wicket 1.5
Hi,
I want to do an AJAX update and then start a file download.
I've found this solution for Wicket 1.4.x
https://cwiki.apache.org/WICKET/ajax-update-and-file-download-in-one-blow.html
This is not working on Wicket 1.5 because this deprecated code:
public void onRequest()
{
getComponent().getRequestCycle().setRequestTarget(
new ResourceStreamRequestTarget(getResourceStream(),
getFileName()));
}
Which is the best way to do this in 1.5 ?

Re: Radio button selection
I think I can give you another option based on Alexander's code. I added
comments to explain how does it works. I didn't test it but If you have any
problem just tell me:
// model that indicates if I have to show the textfield
final IModelBoolean yesNoState = new ModelBoolean();
// this is because when textfield is hidden you can't reference it by
markupid because html component doesn't exists.
final WebMarkupContainer fieldContainer = new
WebMarkupContainer(fieldContainer);
// this indicates wicket to create an id for tag. Necesary to update by
ajax.
fieldContainer.setOutputMarkupId(true);
// textfield to show with isVisible redifined based on previous model
final TextFieldString textField = new TextFieldString(text) {
@Override
public boolean isVisible() {
return yesNoState.getObject();
}
};
fieldContainer.add(textField);
// just a component to agrupate options
RadioGroupBoolean yesNoGroup = new RadioGroupBoolean(yesNoGroup,
yesNoState);
yesNoGroup.add(new AjaxFormChoiceComponentUpdatingBehavior() {
@Override
protected void onUpdate(AjaxRequestTarget target) {
// this is to update container by ajax and consequently textField
visibility.
target.addComponent(fieldContainer);
}
});
yesNoGroup.add(new RadioBoolean(yes, Model.of(Boolean.TRUE)), new
RadioBoolean(no, Model.of(Boolean.FALSE)));
add(fieldContainer);
add(yesNoGroup);

Hi, 1. I guess you need to extend org.apache.wicket.request.resource. DynamicImageResource. (for example, http://code.google.com/p/xaloon/source/browse/trunk/xaloon-wicket/xaloon-wicket-components/src/main/java/org/xaloon/wicket/component/resource/FileResource.java ) Then you should be able to load images from any place you like. 2. Mount your Resource: String resourceKey = your key here; getSharedResources().add(resourceKey, new FileResource()); mountResource(resourceKey, new SharedResourceReference(resourceKey)); 3. Generate link to your image using Image, or custom implementation (for example, http://code.google.com/p/xaloon/source/browse/trunk/xaloon-wicket/xaloon-wicket-components/src/main/java/org/xaloon/wicket/component/resource/ImageLink.java ) On Tue, Nov 22, 2011 at 1:24 PM, crackAT manfred.kram...@everyone.atwrote: I did it outside. but the problem is, that wicket is using for every pic the resourcereference and not only for the application pics.

Re: Can't Reset Form After DropDownChoice OnChange Handled
Not sure what you mean, exactly. The only alternative I can see it to keep
an original copy of the form model (assuming there IS a single) model,
then add an onclick handler() to the reset button, then go back to the
server, overwrite the current model with the original model, then add the
form component to the AjaxRequestTarget so it's re-rendered. This could be
ugly error prone real fast, especially if all of the form fields weren't
covered by a single model. \
Am I missing something here?

Yes, you can reset the form quite easily, with or without Ajax. I haven't
read the rest of the thread, but if you just reset the object that the
form
is referencing all the fields would stay in sync and be 'reset'.

All you need is an AjaxButton with .setDefaultFormProcessing(false)

getForm().setModelObject(new MyEntity());
target.add(getForm());
i.e. set a new empty model object for the form and all its form

Do whatever is the best for your logic.
If this is a create form then use empty Entity. Whatever 'empty'
means in your domain.
If this is an edit form then re-fetch the Entity from the DB by its
id and set it as model object.

Putting together two seperate wicket projects into a multi-module maven project
Hi, I have created 2 separate wicket web projects. Now i want put them together in multi-module maven project and put the dependency as required. Will it give problem when i have have 2 web-inf folders. Example Project A has web-inf and web.xml etc. Project B also has web-inf and web.xml etc. Now i put both Project A and B into a multi-module maven Project named C, and have the pom.xml of project B changed so it includes the dependency of A Finally i want to deploy war of project B. Also should the project A be packaged as jar or war? Thanks Sameer - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: ValidationForm.addPropertyValidators sometimes looks for child properties in parent's model
its very hard to figure out problems like this without having running
code. you can either create a quickstart with a failing testcase, or
even better make a pull request on github that will add the failing
testcase directly into the codebase.

Igorbut you can create a testcase, reproducing the bare bits of code in a
testcase just like you did in the email below. the advantage would be
that i would have something i can play with which makes it much easier
to find the problem.
I will work on a quick start tonight, when I'm not at work. But here's what
I'd like to do, possibly extending Metagen. I have a Report object which
includes an abstract Document object. Document has 3 concrete subclasses,
Book, Article, and Monograph. I have FormComponentPanels for each, which I'd
like to swap in and out. I've used Metagen to create ReportMeta,
DocumentMeta, BookMeta, etc. I'd like to extend Metagen so I can write code
like
IModelBook bookModel =
MetaModel.of(report).get(ReportMeta.document).as(Book.class);
and
IModelString isbnModel =
MetaModel.of(report).get(ReportMeta.document).as(Book.class).get(BookMeta.isbn);
Since I don't want to modify the MetaModel class on my own, I've written a
SubClassModel class like so:
private static class SubClassModelT extends MetaModelT {
private static final long serialVersionUID =
3511732306311269529L;
public SubClassModel(MetaModel? super T superModel, ClassT
clazz) {
super(superModel);
}
@Override
public T getObject() {
return (T) super.getObject();
}
@Override
public void detach() {
super.detach();
}
public static T MetaModelT as(MetaModel? super T
superModel, ClassT clazz) {
return new SubClassModelT(superModel, clazz);
}
}
}
Unfortunately, when the validation system gets its hands on this, it throws a
NPE as it adds the property validators:
Caused by: java.lang.NullPointerException

This happens when Model is that SubclassModelBook.
How would you use Metagen for this case? Is it worth extending it?

Re: Putting together two seperate wicket projects into a multi-module maven project
You can use maven war overlays. But it would be much easier if your two projects would be packaged as jar only. With Wicket there's hardly a reason to require project specific web.xml files in A and B. Sven Am 22.11.2011 16:52, schrieb Sameer Patil: Hi, I have created 2 separate wicket web projects.

Page serialization problem with wicket 1.5?
Hi, There seems to have page data that are not correctly unserialized with wicket 1.5.x. I have done a quickstart application to show you the problem with a ModalWindow using a page (not a panel) : http://apache-wicket.1842946.n4.nabble.com/file/n4097909/myproject.zip myproject.zip How to reproduce the problem : 1- start the application (mvn jetty:run) 2- open your browser : http://localhost:8080/ 3- Click on click me a couple of time (optional!) 4- Enter the label field then submit. You should see submit ok in the feedback panel. 5- Click the open modal link 6- Enter the description field and submit. 7- The model is serialized with all the data and next when the data are unserialized, the description data is lost. Here's the log : using the click me link! INFO - HomePage - Serialized [Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@6da05bdb - nbClick = 0 - label null - desc null INFO - HomePage - Serialized [Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@6da05bdb - nbClick = 1 - label null - desc null INFO - HomePage - Serialized [Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@6da05bdb - nbClick = 2 - label null - desc null Submit form with the label field INFO - HomePage - Serialized [Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@6da05bdb - nbClick = 2 - label ddd - desc null submit modal with the description field INFO - HomePage - *Serialized *[Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@6da05bdb - nbClick = 2 - label ddd - *desc fdfdfd* INFO - HomePage - *unSerialized *[Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@7d98d9cf - nbClick = 2 - label ddd - *desc null* INFO - HomePage - Serialized [Page class = com.mycompany.HomePage, id = 0, render count = 1], bean = com.mycompany.bean.MyBean@7d98d9cf - nbClick = 2 - label ddd - desc null desc has been set to null With wicket 1.4.x it's working just fine (there's a pom.xml.wicket.1.4 in the project if you want to try) : there is no page that is unserialized. If I use a panel instead of a page in the modal window, it's working just fine. So I guess it has something to do with multi-window/multi-page handling... Is there a new option to turn on with wicket 1.5 to have it works like in wicket 1.4?

How to test just a panel using apache wicket?
Hello,
In our project, we have some panels and we embed those panels
dynamically to pages.
public class DoublePanel extends Panel {
public DoublePanel(String id, Panel leftPanel, Panel rightPanel) {
.
}
}
I am not sure how to write unit test just for this class without a webpage.
public class DoublePanelTest {
private WicketTester tester;
@Before
public void init() {
tester = new WicketTester();
}
@Test
public void testDoublePanel() {
tester.startComponentInPage(new DoublePanel(double, leftPanel,
rightPanel));
}
}
I tried to run something like above. But got the below exception. I checked
some sample test case but in all, they have used tester.startPage(xxx.class)
and then used tester.startPanel(). Is it possible to test just the panel
without a webpage?

I did try something like this,
public class DoublePanelTest {
private WicketTester tester;
private class TestPage extends WebPage {
private static final long serialVersionUID = 1L;
public TestPage() {
super();
add(new DoublePanel(double, leftPanel, rightPanel));
}
}
@Before
public void init() {
tester = new WicketTester();
}
@Test
public void testDoublePanel() {
tester.startPage(new TestPage());
}
}
But still I am getting the same exception,
java.lang.NullPointerException
