Re: Remove underline in OrderByBorder link
I think his problem is how to set add the class attribute. In addition,
he probably want another class for each sort direction.

Thx, I agree.but how do I set the CSS for the link in the border and
have that CSS changed when the sort changes? By default the link has a
void CSS while the Border CSS manages the sort changes, and I am not sure
how to manage the link CSS. The OrderByBorder hieracharchy is:
Border (with CSS modifier)
--link (void CSS modifier)
Which renders as
td class=myCSS(either asc, desc, or normal)
a class=
.
I haven't found an easy way to get to and manager the link part.
If you have any ideas, let me know.

Re: Comparing JSF and Wicket
Thanks Scott. Nice experiment. In my experience, not many organizations would be willing to commit resources for such a research. But the result is hard to dismiss: after all, when everything is said and done, the most important factor in most companies is - how fast can you deliver this? Still, I'd like to ask - can you point to any advantage JSF has over Wicket? Anything at all? Scott Swank wrote: My company compared several frameworks and settled on either JSF or Wicket. We then had a 2 week development effort implementing the same proof-of-concept app with 2 teams of 4 devs each. Everyone was at least somewhat familiar with JSF, while only one person in our department had ever worked with Wicket. After 1 week the Wicket team was done, while the JSF team was struggling over whether to use facelets or jsp for rendering, which rendering implementation to use, which ajax library to use (and how that required re-deciding some of the previous items). Now many of those problems that plagued the JSF team are one-time decisions that are not indicative of day-to-day development. That said, every developer who worked with Wicket ended up advocating for it as our web framework, even though most of them had initially preferred JSF. In fact, after seeing the Wicket JSF code side-by-side most of the devs on the JSF team voted for Wicket, as did the rest of the department. In the previously recommended article http://ptrthomas.wordpress.com/2007/05/14/a-wicket-user-tries-jsf/ go down to [The List Forums Screen] and compare the JSF tags with the Wicket html. We can hire presentation-layer developers who only need to know html css. Also, go into a working Wicket page and screw up something (misspell a wicket:id, whatever). Now examine the exception you get. It will likely describe in rather clear terms what is wrong. Now try this with JSF. Now take your problem and post it to the Wicket forum (perhaps with a different e-mail address) and ask for help. Now try that with JSF.

Re: Facebook Wicket Integration
Thanks Cao, but I don't see how this helps me. Let me further explain my situation. 1) I need to display links to the users of my facebook application. These links are DYNAMIC, so I can't put them in the markup. I have to use some sort of wicket Link component. 2) In your example, the URLs are relative URLs, as opposed to the absolute URLs that I want to display to the user. In my application, all the links (currently) are relative links, i.e. when I hover over the link when the application is running in facebook, the URL displayed at the bottom left corner of the screen is: http://my-server-doamin/page-address But I would want them to be: http://apps.facebook.com/application-name/page-address My trouble with achieving this is described at my previous post on this thread.

Thus, for them, the issue is decided more an economical merits, then on its design/architectural ones. Always look at the facts, never just go on a hunch. What may sound like common sense, especially from a managerial point of view, not always is that sensible. In this case, while having a whole bunch of standard components might sound good and sell well, you have to wonder how much time it actually saves you. Very often you'll have to customize components to exactly fit your needs. How hard is that, and is it possible at all is something you need to look at. The fact that component lib X has a datagrid component doesn't mean it fits your needs. It might be inflexible or - when it is flexible - hard to use because the API is big and clumsy. The great thing about custom components is that extending a base component often is just as easy or even easier than having to figure out an of the shelf component that does it all but needs to be configured for a specific use case. Also, because you'll make it fit to your needs without having to do lots of configuration, you'll likely avoid a lot of code duplication, and it might be easier to optimize for specific cases because you can access internals more easily. This is a classic advantage a standard solution usually offers - a thriving ecosystem. (than again, I've got to admit, I don't really know that much about JSF's ecosystem...). And again, look at the facts. If you look past the marketing slogans en count the available high quality components for the two frameworks, I honestly don't think the difference is that huge. I actually expect Wicket's community to do a bit better. And we don't need as many components because extending a baseclass is very often a more efficient way of customizing than designing complex components upfront and guiding them through configuration. How many Wicket components are there, and how mature are there? Are there tables with sorting, filtering, scrolling, paging etc.? Are there tree-controls with all the typical tree-functions? Is there Ajax support, as well automatic fallback for non-javascript browsers (and what about comet)? You'll have to do your homework here. It's simple, just check out the Wicket core projects, and a bunch of wicket-stuff projects in your IDE of choice, and look for an inheritance view (F4 in Eclipse) of the Component class and see what components there are. We can't really give meaningful numbers imho, because many components gradually go from covering just base functionality to supporting very specific functions (like TreeTable or tables with sorters and filter fields). You should also consider doing the same thing for the IBehavior interface, because often you can add behavior to a component through behaviors. Final remark... it seems that many people are always looking for 'winners' and 'losers'. Why don't you just take the projects you're thinking off, see what you really need and match that with the frameworks you're evaluating, and try to get a hunch of what it would be like to actually do these projects with the frameworks so that you can decide whether it would fit your needs?

Hi everyone, Just wanted to say a quick thank you to Cemal, Al et al for organizing this event, last night was very informative, especially the Terracotta presentation.

Re: Questions about wicket features
This assumes that the hacker correctly guesses the application key
(which you of course changed from the default setting), or has access
to your application to harvest URLs.
Making the SunJceCrypt user specific is as simple as:
new SunJceCrypt() {
@Override public String getKey() {
return MySession.get().getUserKey();
}
}
And all you have to do is implement your own user key generation that
generates a key based on some random information and is constant
throughout the session (e.g. md5 sum of a salt + Random.nextInt).

Re: Questions about wicket features
CSRF uses urls to do something on another side right? for example img src= http://bank.example/withdraw?account=bobamount=100for=mallory; How would that work in a default wicket application? Is it really so stupid developed that these kind of things uses client side state? So this cant be done with just an url. So you have to have real scripting.. So for this to work in wicket you have to know upfront so many things.. First the page id of the bank transfer page.. Which is pretty random. Only if all users would go over the same path always to the same page then the id could be guessed. Then it has to get the right form, fill in the right values and do the submit And do modern browsers allow js script like that? johan On Thu, Aug 7, 2008 at 10:54 AM, Arthur Ahiceh [EMAIL PROTECTED]wrote: 4.

Javascript in onBeforeRender
Hello everyone,
I have a small problem. I have a wicket component and the idea is that the
programmer can add numerous messages to it and whenever the component is
rendered some javascript is executed to iterate over the messages and
displays them.
I thought that I could simply override onBeforeRender(), or onAfterRender(),
but I simply can't figure out to append javascript. Basically I just want to
have a line of javascript executed, like
messagebox.displayMessage('asdasdasd').
Before someone asks why I just don't add a label with the message, the
messagebox is dragable, fades after a while and should display messages for
a set amount of time (before the next message is displayed) and should also
be used on client side without requests.
Any thoughts? Help would be appreciated.
Tom

Re: How to protect against Session Fixation attacks?
no what you see is that by default the http session store has a new window browser detection (new pagemap) It needs that because of the way pages are stored and rollbacked. The DiskPageStore doesnt need that it can get all the pages back that it wants so for that the new window detection is by default not enabled. Old sessions are not cleand up with the diskpagestore?

How to include some parameters in template? Custom tag? Component?
I have some page template which I want to include some blocks which look same but some minor differences. Something like this ... body Please try our my:productInfo category=foodmy:idapple/my:id/my:productInfo and play on our cool my:productInfo category=hardwaremy:idapple/my:id/my:productInfo computers. /body So, after rendering my:productInfo could be replaced by some html which may contain given product description, image, link to buy, etc. I cannot to use span wicket:id=food-apple because it less obvious and cannot give me structured parameters (like category, id) and I have to add each wicket:id in .java-file, which could be annoying to change two places. I found wicket:component tag, but it's experimental and not recommended to use. I think to implement own IComponentResolver to handle my:productInfo tags. Is it the best way? Or is there other way to do it? -- WBR, kan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Comparing JSF and Wicket
If you can find JSF components that do exactly what you want then JSF
is more compact. If, however, you find JSF components that do nearly
what you want, but you have to add a bit of functionality, well then
you're into the lovely world of phase listeners and the
request/response life cycle. Dante located JSF phase listeners within
the 4th circle of hell if I remember correctly.
One of the first ah ha moments I had with Wicket was when I needed
to copy customer names from one field to another. If a customer
purchases several items (tickets to shows, books a tour, reserves a
hotel room) then the guest name associated with one item is typically,
but not always, the guest name for all of the items. With a nominal
amount of reasonably clear code I was able to create a behavior that I
simply attach to all of the first names and last names. It copies the
value of one field to all of the matching fields that are empty and
updates all of these fields via ajax. It's 22 lines if you don't
count whitespace braces and it is completely reusable. It can be
attached to any two or more form components and it just works.
public class ModelPropagationBehavior extends AjaxFormComponentUpdatingBehavior
{
private static final long serialVersionUID = -451063727688504933L;
public enum PREBUILT
{
FIRST_NAME, LAST_NAME;
public ModelPropagationBehavior getBehavior()
{
return new ModelPropagationBehavior(name());
}
}
private final String name;
public ModelPropagationBehavior(String n)
{
super(onblur);
this.name = n;
}
private String getName()
{
return name;
}
private boolean hasMatchingBehavior(Component component)
{
for (Object behavior : component.getBehaviors())
{
if (behavior instanceof ModelPropagationBehavior
((ModelPropagationBehavior)
behavior).getName().equals(this.name))
return true;
}
return false;
}
@Override
protected void onUpdate(final AjaxRequestTarget target)
{
final FormComponent thisComponent = getFormComponent();
thisComponent.getForm().visitChildren(new IVisitor()
{
public Object component(Component otherComponent)
{
if (otherComponent.equals(thisComponent))
return
CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;
if (hasMatchingBehavior(otherComponent)
otherComponent.getModelObjectAsString().isEmpty())
{
otherComponent.setModelObject(thisComponent.getModelObject());
target.addComponent(otherComponent);
return
CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;
}
return CONTINUE_TRAVERSAL;
}
});

well, it is the way you setup the model by doing new model(value), so
the model acts as the container for the value rather then some glue
between value and some other container such as a class field. see the
models page on the wiki.

modify an arbitrary dom element
I have a case where I want to modify the css class of the dom element that contains the component I'm working with. I found the wiki page: http://cwiki.apache.org/WICKET/how-to-modify-an-attribute-on-a-html-tag.html but that will allow me to modify the component only. Specifically what I'm doing is something like: ul li class=selectedItema href=# wicket:id=homePageLinkHome/ a/li /ul so I actually want to modify the css class of the containing li element (not the a element).

SecureMarkupContainer
I created a SecureMarkupContainer following Maurice's example (http://
www.nabble.com/Swarm%3A-Authorization--for-WebMarkupContainer-
td17206272.html#a17219441), with the only difference being it's its
own class (not subclass). For some reason, the component doesn't
seem to be added to the page after authenticating. The correct
values are returned by typeOfData.isAuthenticated(). However, it
seems whatever hides/displays the component is not getting executed
or executed correctly. Below are some snippets of code:
Search:
SecureMarkupContainer typeOfData = new SecureMarkupContainer
(typeOfData);
add(typeOfData);
Search.html:
div wicket:id=typeOfDatasecurity works!/div
cnv.hive:
permission
org.apache.wicket.security.hive.authorization.permissions.ComponentPermi
ssion ${cnv}.Search:typeOfData, inherit, render, enable;
Also, I have a few other secure components working fine (ie
SecureLink). Any ideas?

Re: How to Embed PDF in a Web Page

Help!! TextField in ListView = NULL
Hi,
I am very new with wicket and I have a problem with TextField within
ListView , I try to getModelObject from the Textfield but return NULL ?
I am trying my best to find the solution, unfortunately I am running out of
time with my final project. Already spent 2 days dealing with this small
problem :,(
Hope you guys can help. Below is the some part of the codes:
textfieldModel = new Model();
textField = new TextField(textfield,textfieldModel );
listItem.add(textField);
listItem.add(saveLink = new Link(saveLink) {
public void onClick() {
String myText = (String) textField.getModelObject();

Re: Comparing JSF and Wicket
2008/8/7 nlif [EMAIL PROTECTED]: While it is very good to know that it's relatively easy to develop Wicket components, bear in mind that management (at least mine) is more easily convinced when presented with a wide selection of 3rd party component libraries, since that provides an alternative to allocating time and resources of our own developers. Thus, for them, the issue is decided more an economical merits, then on its design/architectural ones. Your company should concentrate on what it does as its core competency as that will bring you the most value for time invested. Based on past experience with many companies, I can most glibly and universally sum this up as: Don't write a ticketing system unless you sell ticketing systems. You are presumably building web apps because you think you're quite good at it (or perhaps will be), and you're worried about working at the right level of abstraction to achieve good productivity. You're concerned that Wicket might be at too low a level of abstraction compared to JSF, because JSF has a plentiful array of off-the-shelf components that you think will let you work at a higher level of abstraction, and therefore you'll be more productive with it. It's a nice idea. It certainly looks tempting. Unfortunately, it just isn't the case. Why is that? Go and read Joel Spolsky's article on leaky abstractions[1]. Right now: http://www.joelonsoftware.com/articles/LeakyAbstractions.html Good to have you back. Here are just a few reasons why pre-built components in JSF are not the answer. At some point, normally just after you've completely wedded yourself to a component, someone important will want you to change something that on the surface should be trivial. At this point, you will need to unpick the entire component and figure out how it works, and change it. This will be hard. You will probably introduce bugs. Unless it's a component with a lot of distinct regions of complexity, it will probably be so hard that you may as well have developed the code yourself from scratch (in either JSF or Wicket). Reading code is harder than writing it. Anything remotely complex will need to you restyle it all to make it fit in with the rest of your web pages. This will likely be painful unless the component developer has a clue. Nine times out of ten, it will take you so long to find the component you need, test it works in your environment, make sure it does what you need, make sure it probably does what you might need, discover it doesn't, find another component that does, sort out the licensing, file a purchase order for it, etc. etc. that you could have developed something in Wicket that did exactly what you wanted in half the time. It seems to be the case that if the component is sufficiently complex that you think you will save time/money by buying it in rather than building it, it doesn't do what you want. There are only about five or six truly universal components that are applicable to almost everyone. These are: tree, tree but in a table, sortable paginated data-driven list, date picker, modal pop-up window, AJAX auto-complete drop-down. I can't think of any others, but there might be a couple. Wicket has all of these. Which you'd know if you'd bothered to look at the examples, which are live and prominently linked from the site. Sorry to sound harsh, but how much web development are you going to do? Hmmm? Eight hours' worth? Go use PHP or JSP or DHTML or whatever. Your use case isn't complex enough to be having this discussion. Eight months' worth? What? You're going to make a decision without investing a day in each option at least? Are you crazy? How many Wicket components are there, and how mature are there? Are there tables with sorting, filtering, scrolling, paging etc.? Are there tree-controls with all the typical tree-functions? Is there Ajax support, as well automatic fallback for non-javascript browsers (and what about comet)? Come back here when you have real questions that you can't answer for yourself in ten minutes. http://www.justfuckinggoogleit.com/search.pl?query=wicket+tree http://www.justfuckinggoogleit.com/search.pl?query=wicket+ajax http://londonwicket.org/content/LondonWicket-ListEditor.pdf etc. etc. etc. Alastair - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: 7th August London Wicket Event
Thanks for the kind words. I really liked Carl's Terracotta stuff - very cool. Wille's presentation on his WicketRAD framework was also great. It's really cool to see people getting inspired by and building on people's code from previous meet-ups! I can't begin to tell you how rewarding that is. ;-) Thanks very much to everyone who came along, asked such good questions and gave the event such a nice feel. I'm definitely thinking about increasing the frequency if people are keen (even if it's a less formal gathering in a pub somewhere or something). It's somewhat dependent on the number of people who'd like to give talks and things. Who'd be up for a monthly event? While we're on the subject, who might be up for doing a quick talk at the next one? I was really impressed by the scope and preparation that went into the talks this time around, but if you just want to do a quick demo of your Wicket-based site, or give a five minute talk with no slides and must arm-waving, that would be cool too. Thanks again, Alastair P.S. Apologies for the slightly warm beer! It was cold at 6:15pm, but the usual rooms next to a kitchen (with a fridge) weren't available this time around. I promise we'll fix that for next time! 2008/8/7 Chris Miller [EMAIL PROTECTED]: I'd also like to pass on my thanks, I enjoyed meeting and chatting to you all and I learnt a lot in the course of the evening both through the presentations and just chatting informally. It's great to see such friendly and talented people involved in this project. If anyone reading this happens to be in/near London when one of these events is on, I can say it's well worth heading along to regardless of your level of experience with Wicket. Cheers, Chris Yiannis Mavroukakis-3 wrote: Hi everyone, Just wanted to say a quick thank you to Cemal, Al et al for organizing this event, last night was very informative, especially the Terracotta presentation.

Re: AjaxButton does not work
This may be a client tag interpretation problem? Try using gt;gt;
instead of . I don't think inside HTML attributes is valid HTML.
Use firebug and/or the wicket ajax debug window (link bottom right on
your page) to see what's going on.

Do you have any form validation going on? If yes implement the onError
method on the ajax button. Example:
form.add(new AjaxButton(order) {
@Override
protected void onError(AjaxRequestTarget target, Form form) {
//Ops we got some errors, show them in a feedback panel
target.addComponent(feedbackPanel);
}
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
//Do whatever you need here :)
setResponsePage(Index.class);
}
}.setOutputMarkupId(true));
Hope that helps.

Hello All,
I encounter a problem while I am using an AjaxButton.
In my form page i create an Ajaxbutton that I attach to a markupContainer
and in my HTML I add the folowwing HTML code :
input type=button value= wicket:id=selection /
The button is set default form processing to false.
The problem is that when i click on this button nothing happens !!
I have the same problem with ana AjaxSubmitLink.
I use the Wicket framework 1.3.4.
Can someone help me to see what is wrong with that button ??
Thanks
Bertrand

Re: Help!! TextField in ListView = NULL
Have you done any web development before using Wicket?
If so, you should be able to solve this problem by asking yourself the
following questions:
What happens if you click a link on a web page?
Do you think the browser sends the data in a text field on the page to
the server if you click a link?
What about if you put the input tag in a form and click a link?
What about if you put the input tag in a form and click a submit button?
In short, I'd suggest thinking a little more about the fundamentals
before playing around with user input in listviews. Have a look at the
examples.
Alastair
P.S. There are ways to do what you're trying to do without needing to
put things in a form, etc., but they involve AJAX and therefore
probably aren't the best solution for whatever it is you're trying to
do.

I have add testsListView.setReuseItems(true), but still doesn't work.
:confused: Hope anyone able to give me hints and guide me to the correct
implementation... thanks
Refer to HERE below:
ListView testsListView = new ListView(tests, tests) {
public void populateItem(final ListItem listItem) {
final Test myTest = (Test) listItem.getModelObject();
final Link editLink1;
listItem.add(editLink1 = new Link(editLink) {
public void onClick() {
Long test_id = myTest.getTest_id();
TestCanvas testCanvasPage = new TestCanvas(test_id);
setResponsePage(testCanvasPage);
}
});
editLink1.add(new Label(title, myTest.getTitle()));
String test_dateNow = df.format(myTest.getTest_date());
listItem.add(new Label(date, test_dateNow));
listItem.add(new Label(time, myTest.getTest_time()));
listItem.add(new Label(duration,
myTest.getTest_duration()));
listItem.add(new Label(status, myTest.getStatus()));
HERE --testMeModel = new Model();
testMeField = new TextField(testMe,testMeModel);
listItem.add(testMeField);
Lecturer lecturer =
getQuestionnaireService().getLecturer(myTest.getLecturer().getLecturer_id());
String lecturerName = lecturer.getPrintableName();
listItem.add(new Label(creator,lecturerName));
final Link removeLink = new Link(remove){
public void onClick() {
getQuestionnaireService().removeTest(myTest);
TestManager testManagerPage = new TestManager();
setResponsePage(testManagerPage);
}
};
listItem.add(removeLink);
removeLink.add(
new JavascriptEventConfirmation(
onclick,
Delete test of +
myTest.getTitle() +
on +
myTest.getTest_date()+
, time +
myTest.getTest_time()+
?
)
);
final Link testMeLink;
listItem.add(testMeLink = new Link(testMeLink) {
public void onClick() {
HERE --String test_Me2 = (String) testMeField.getModelObject();
System.out.println(#);
System.out.println(### test_Me = +test_Me2);
System.out.println(#);
info(### test_Me = +test_Me2);
}
});
}
};
HERE -- testsListView.setReuseItems(true);
border.add(testsListView);

I am trying my best to find the solution, unfortunately I am running out

Hope you guys can help. Below is the some part of the codes:

RE: Questions about wicket features
Hello I've browsed over the wicket documentation and examples. There are a couple of things I don't seem able to determine. So I would really appreciate your input on this questions. 1. Can I write a web application without coding any HTML whatsoever?... I mean, is there some kind of html or whole page component which renders an entire HTML page? You need to use something like Echo2 or Echo3 to write pure Java web apps with no HTML whatsoever. All the HTML and all the AJAX is completely transparent to the developer - it's more like writing a desktop app than a web app which has benefits if you come from a Java/C++ background and some disadvantages if you like having the power to hack around with HTML and Javascript code. With wicket you're still in control of the markup (HTML) which means you have to write it but it's pretty straightforward. There is support for a single section of markup to be overridden (inheritance) from a base page markup to a derived page markup which means you can perform some level of markup reusability at the page level. On some occasions I've found the need to have multiple sections in a base markup to be 'overridable' in a derived markup pages but this is not yet possible as far as I know. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: 7th August London Wicket Event (6th August!)
Yiannis, Chris, This is good to hear, thanks. We've been getting plenty of positive feedback since we started this thing well over a year ago, albeit mostly verbally until now. Perhaps your reviews here will make others aware of how much our guests enjoy and look forward to these events. The quality and variety of the presentations and the increasingly interactive atmosphere we have been gently encouraging is definitely heading in the direction I had envisaged from the start. There are a few more improvements and unorthodox ideas that I want to gradually introduce in the months to come which I think people would get into, especially now that we seem to have established a healthy core group of regulars. I'll talk to Al and we'll come back with some suggestions regarding the frequency (if I get a chance I may set up a little Wicket component for our http://jweekend.com/dev/LWUGReg/ registration page to gauge your feedback so we don't swamp this mailing list). Several people have asked me about this, so perhaps we could consider going back to once a month, but I am mindful that we do nothing to disturb the good balance and successful events we are currently enjoying. Regards - Cemal http://www.jWeekend.co.uk http://jWeekend.co.uk PS To those who were present on August _6th_ (I don't know what event on the 7th you got us mixed up with Yiannis, but we'll accept the compliments ;-) , don't forget to send http://jweekend.com/dev/ContactUsBody/ jWeekend a note if you'd like to be entered in the draw for the pre-paid http://manning.com/dashorst/ Wicket In Action MEAPS edition , let's say by the end of next week. Chris Miller wrote: I'd also like to pass on my thanks, I enjoyed meeting and chatting to you all and I learnt a lot in the course of the evening both through the presentations and just chatting informally. It's great to see such friendly and talented people involved in this project. If anyone reading this happens to be in/near London when one of these events is on, I can say it's well worth heading along to regardless of your level of experience with Wicket.

The only gripe I've got (besides warm beer :-P ) is the frequency of the event..I think bi-monthly is far too far apart for such a fast paced framework as Wicket..Any chance this can be done on a monthly basis?
