Getting position of elements in a ListView
Hi all,
I use a ListView holding Components to implement a dynamic form, i.e.,
where the user can add and remove DropDownChoices herself. (See
http://cwiki.apache.org/WICKET/forms-with-dynamic-elements.html.)
Now, a problem is the removal of elements when the user clicks the
remove link next to a DDC. My original code looks like that:
ListView menuList = new ListView(MENU_LIST_ID, dropdownMenus) {
public void populateItem(final ListItem item) {
final DropDownChoice choice = (DropDownChoice)item.getModelObject();
item.add(choice);
AjaxFallbackLink removeMenuLink = new
AjaxFallbackLink(REMOVE_MENU_LINK_ID) {
public void onClick(final AjaxRequestTarget target) {
// Parent is the ListView, its model object is the
list of menus.
ListPositionAwareDropDownChoice choices =
(ListPositionAwareDropDownChoice)
item.getParent().getModelObject();
choices.remove(choice);
target.addComponent(enclosingContainer);
}
};
removeMenuLink.add(new Label(REMOVE_MENU_LINK_TEXT_ID,
removeMenuLinkText));
item.add(removeMenuLink);
}
However, choices.remove(choice) doesn't always work because the list
doesn't seem to contain the DDC choice, i.e., equals() is not true.
So I thought of removing the DDC by their position in the list, but
that means I have to store it myself. Currently, I extended DDC,
adding getPos() and setPos(). The line where the removal happens now
looks like that:
choices.remove( ((PositionAwareDropDownChoice)choice).getPos() );
It seems a bit clunky and verbose to me. Does anyone know of a better way?
Cheers,
Thomas

Important concept in wicket? Please advise
Hi to all,
I want to display one label when I click one button.
I have wrote the code. but i am not able to display that message.
my code is looking like

validationMessage);
final Label filterPanelMsgLabel = new
Label(validationMsgLabel,
filterPanelMsgModel);
filterPanelMsgLabel.setEscapeModelStrings(false);
filterPanelMsgLabel.setOutputMarkupId(true);
add(filterPanelMsgLabel);
//in submit button,
AjaxSubmitLink saveButton = new AjaxSubmitLink(saveButton, this)
{

{
// To display the string in html page.
setValidationMessage(Please enter valid date);
}
}
//getter and setter methods
private String validationMessage =;
public String getValidationMessage() {
return validationMessage;
}
public void setValidationMessage(String validationMessage) {
this.validationMessage = validationMessage;
}
in FilterPanel.html
span wicket:id=validationMsgLabel[Message goes here]/span
in the above code, i did not get any error in console. And I am not able to
view the message.
Why? Please advise.
Thanking You.

However, even if you slow it down to 1 second per hash a cracker will easily be able to do dictionary attacks with his botnet, so it does not adequately protect weak passwords anyway. And 1 second per hash is quite expensive for a high volume site. So I still think you're better of make sure you don't lose your password database instead of making the login slow.

Re: Wicket Modal Window
I had similar problem. I changed Button to AjaxButton and override onError()
and everything was alright. Note that you must call setOutputMarkupId(true)
on
components which use in another ajax-enabled component (like AjaxButton
is..).
In case below I must call feedback.setOutputMarkupId(true) where feedback =
new Feedback(feedback's wicket id).
like this:
Button btnOk = new AjaxButton(btnOk, form) {
@Override
protected void onSubmit(AjaxRequestTarget target, Form
form) {
// something to do, when everything is ok and
valid...
}
@Override
protected void onError(AjaxRequestTarget target, Form
form) {
target.addComponent(feedback); // show feedback
message in feedback
component
}
};
This works ok.

you must add the component you want to update to the target in onSubmit
method, like this:
target.addComponent(filterPanelMsgLabel);
The code, tells to wicket which component to update on ajax request.

Re: Wicket 1.3 rc1 Relative URLs not working properly
Hi, I encountered this problem a week ago, too, and digged a little into code and forum. Here's my summary: the problem seems to be the /* filter mapping. If you specify a /app/* filter mapping, relative URLs work just fine. In my base-page-class (all my pages are derived from it through Wicket's great markup inheritance) my stylesheet is referenced in the head-section by a relative reference like link rel=stylesheet type=text/css href=style/myapp.css / Checking the generated HTML in the browser (when using /* filter mapping) shows that this reference is modified by Wicket, so that it now reads link rel=stylesheet type=text/css href=../style/myapp.css / This is an invalid path and addresses a wrong location. I digged into the code and found that relative stylesheet and image references where automatically prepended by ../ by ServletWebRequest.getRelativePathPrefixToContextRoot(). This seems to work well for the /app/* filter mapping, but fails for /* (since theres no parent-directory in between to skip) I currently decided to use the /app/* filter mapping. Following workarounds came into my mind: 1. use of absolute references like /myapp/style/myapp.css. pro: works, Wicket doesn't modify the absolute paths cons: must code the context-path into all style and image references, which is a NO GO 2. use of /app/* filter mapping pro : works cons: after having seen the much nicer /* mapping I want to use it :-)) 3. in HTML it is possible to add a base href=http://localhost:8080/myapp// line into the head section, which is used to resolve all relative references pro : would be great, since it allows the use of relative URLs, and it must be configured in just one place (the base-page's head section) would also be great to use when using a front end server (Apache), since references would be resolved to root context cons: since Wicket isn't aware of the base tag, relative references are still modified and prepended by ../, so no stylesheets/images were found 4. fix it :-)) Related threads and infos: - is it a bug - use of /* filter mapping - http://www.nabble.com/is-it-a-bug--%28using-beta-4%29-tf4649929.html#a13284326 - Wicket behind a frontend proxy - http://www.nabble.com/Wicket-behind-a-front-end-proxy-t4776982.html - http://cwiki.apache.org/WICKET/best-practices-and-gotchas.html#BestPracticesandGotchas-WicketServletMapping Jeremy Levy-3 wrote: WICKET-1205 On Dec 3, 2007 5:16 PM, Jeremy Levy [EMAIL PROTECTED] wrote: Sorry for now explaining this properly.

two dropdownchoice inputs combined as a fragment/panel/component ??
Hi all, I'm now on the second phase of the project I'm working on and starting to find cases where I'm repeating code which means one thing : refactor. As an example I've got two dropdowns that select make and model with a bit of ajax to populate the second dropdown, these are always going to be together so it makes sense to permanently couple them and be done with it. What is the best way to prevent duplication in a case such as this while still keeping the ability to validate etc? Many thanks Simon

The whole point of using random salts + slow hashing is to make even simple passwords hard to crack when your DB is stolen. I certainly don't disagree with you (or the author) that using BCrypt is better that MD5. But it won't protect your weak passwords. Sure, it'll take a little more effort; but the protection will not be enough. I've seen dictionary attacks on actual password databases with a relatively small dictionary succeed on 50% of the passwords. With botnets or other distribution methods, testing an entire dictionary (plus simple variations) will always be feasible. And the users will blame YOU for losing it, so don't. Hey, there's some good security advice. Don't worry about your password hashing scheme, just don't let anyone steal your database. Ask the guys at Reddit how that worked out (http://blog.moertel.com/articles/2006/12/15/never-store-passwords-in-a-database). I'm not saying NOT to use a password hashing scheme. But I think in the reddit case blaming it on the absence of password hashing is just finding a scapegoat; they had some MUCH MORE SERIOUS security failures when they let their database get stolen. Security failures you are NOT going to fix by introducing password hashing. For example, some elementary questions: 1) what was their security policy that allowed somebody who is unauthorized to access the backup database? 2) if the backup contained confidential information, why was it not encrypted? My original point was that MD5 hash plus salt is adequate in most use cases; and I still stand by that. If you're developing a high profile site, then I STRONGLY suggest you hire a security expert to audit your entire site: security policy, operating procedures, and systems.

Re: wicket cluster on tomcat 6
It has to do with the page store. Note that the back button will work, but clicking on links on the page after you use the back button will cause page expired. See: http://www.slideshare.net/jcompagner/session-stores-page-maps-and-pages/ if you want the nitty gritty details. But I still think you should first verify that this is actually what is happening.

Wrapping up the Amsterdam Wicket Meetup
Hi all, Thanks for all your kind words. I did have an excellent time last friday, and I'm very happy to hear everyone else did too. There were just a couple of things that didn't really work out - like the hackaton for example. Maybe it's because it was the first time, maybe it was because we were running an afternoon/evening show instead of the whole day. I'd like to do that differently next time. Also, I think the programme was quite pressing, given that it was at the end of the week *and* at the end of the day. Next time, I'd like to have some more kick ass demoing on stage just to keep up the vibe. I was exhausted afterwards :) But it was incredible to have so many people show up and stick around until 11 PM. At the peak, I counted 74 people in the room and given the fact that we had 92 people signed up, I think that was much more than we could've ever wished for. It says something about the community and the project when sending out 2 emails (one to the user list, one to the NLJUG list) is enough to bring together such a crowd. It also says something about the type of event - low barrier, easy access, and free. Community driven. It makes an excellent addition to the much broader targeted ApacheCon conferences [1], attracting new people to the Apache communities. I'm looking forward to the next edition :) What if we just block the same room again around the ApacheCon Europe in April? Not to be an alternative to ApacheCon - rather as an addition.

RE: Wrapping up the Amsterdam Wicket Meetup
Hi all, Just to warn you all - I've taken the liberty of making some reservations around the ApacheCon :) There's two possible locations: the building we were in, or another one which is quite NEXT to the ApacheCon venue (Pakhuis de Zwijger [1]). I've booked for the Friday before the ApacheCon (April 4), monday 7 and tuesday 8 of april. But I really need to discuss this with the ApacheCon Planners, as I don't want to mess with their training schedules on monday and tuesday (which are very important for ApacheCon revenues). So maybe the friday before is the best date after all. Anyway, the rooms are booked, start thinking about the content ;) -- Arjé [1] http://www.dezwijger.nl/index.php?nid=184 -Original Message- From: Arje Cahn [mailto:[EMAIL PROTECTED] Sent: dinsdag 4 december 2007 16:30 To: users@wicket.apache.org Subject: Wrapping up the Amsterdam Wicket Meetup Hi all, Thanks for all your kind words.

Re: Wrapping up the Amsterdam Wicket Meetup
Congratulations, it sounds like you all had an experience to remember in Amsterdam. I've had a quick look at some of the slides (and photos); these seem to back up my hunch! It's already been around 6 months we since we started-up the http://jweekend.co.uk/dev/LWUGReg/ monthly London events ( http://jWeekend.co.uk jWeekend with http://herebebeasties.com Al Maw ). We have had varying attendances to date and our guests have told us how much they have enjoyed the events and presentations (although most of our lot seem to be too shy to post about it ;-). Maybe looking ahead, we can also organise an annual event where we try to get together our London Wicket Users Group event with yours and those of anyone else in the region who can make the trip to wherever we decide to run such an event; a European Wicket event peut-etre? jWeekend would be happy to contribute to the funding and organisation of this event too. If we give people plenty of notice and have a nice set of presentations lined-up, I imagine we'd have quite an event on our hands!

Change: Tree has all nodes collapsed by default
Hi, before today the default behavior for wicket Trees was that all nodes were expanded by default. This caused problems with lazily initialized modes (e.g. file system model or JSR model) where wicket attempted to load the entire data during tree render. So I changed the default behavior to have all nodes collapsed. If you want to have all nodes expanded, just call tree.getTreeState.expandAll() on your tree. -Matej - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: How to dynamically generate HTML page?
I looked into the example wicketstuff-crud, this is basically in memory
database with basic CRUD operation. this is not what exactly I am looking.
Let me restate the question. We have application where in user can create a
webpages using web designer by drag-n-drop where is html elements like text,
image, selection box, combo box and save it in DB.
It will be Json format parse it to POJO and store in DB. for example Image
object looks like this
which has got position, style, etc .
[{position:({left:60, top:40}),
size:({width:100,height:80}),
positionTop:40,positionLeft:60,sizeWidth:100,sizeHeight:80,
cssClass:,
style:left:60px;top:40px;width:100px;height:80px;,
]}}]})
Now we need to read from the DB and reconstruct the same Image object has a
html page. We can construct the above object with HTML tags.
But the question is how to display this html pages, since it exists only in
memory and also how to navigate to this newly created page.

Re: How to dynamically generate HTML page?
Generate on one side the html by a servlet or special template
generator, that reads in your db data and generate the component
structure on the other side.

Re: Wrapping up the Amsterdam Wicket Meetup
I already replied on wiki on eelco's popup about the meeting around apache con eu. My idea was also tue (on the training day) or fri (after conf) but fri is a bit to late, last sessions start at 15:00 and every body would be a bit worn down i guess. So maybe the friday before it does make sense except for the people that will not follow the trainings anyway... 2007/12/4, Arje Cahn [EMAIL PROTECTED]: Hi all, Just to warn you all - I've taken the liberty of making some reservations around the ApacheCon :) There's two possible locations: the building we were in, or another one which is quite NEXT to the ApacheCon venue (Pakhuis de Zwijger [1]). I've booked for the Friday before the ApacheCon (April 4), monday 7 and tuesday 8 of april. But I really need to discuss this with the ApacheCon Planners, as I don't want to mess with their training schedules on monday and tuesday (which are very important for ApacheCon revenues). So maybe the friday before is the best date after all. Anyway, the rooms are booked, start thinking about the content ;) -- Arjé [1] http://www.dezwijger.nl/index.php?nid=184 -Original Message- From: Arje Cahn [mailto:[EMAIL PROTECTED] Sent: dinsdag 4 december 2007 16:30 To: users@wicket.apache.org Subject: Wrapping up the Amsterdam Wicket Meetup Hi all, Thanks for all your kind words. I did have an excellent time last friday, and I'm very happy to hear everyone else did too. There were just a couple of things that didn't really work out - like the hackaton for example. Maybe it's because it was the first time, maybe it was because we were running an afternoon/evening show instead of the whole day. I'd like to do that differently next time. Also, I think the programme was quite pressing, given that it was at the end of the week *and* at the end of the day. Next time, I'd like to have some more kick ass demoing on stage just to keep up the vibe. I was exhausted afterwards :) But it was incredible to have so many people show up and stick around until 11 PM. At the peak, I counted 74 people in the room and given the fact that we had 92 people signed up, I think that was much more than we could've ever wished for. It says something about the community and the project when sending out 2 emails (one to the user list, one to the NLJUG list) is enough to bring together such a crowd. It also says something about the type of event - low barrier, easy access, and free. Community driven. It makes an excellent addition to the much broader targeted ApacheCon conferences [1], attracting new people to the Apache communities. I'm looking forward to the next edition :) What if we just block the same room again around the ApacheCon Europe in April? Not to be an alternative to ApacheCon - rather as an addition. This will give people even more reason to attend the ApacheCon. Let me know.

Re: Component toString() implementation and java.lang.StackOverflowError
This sounds famliar. I think we already fixed something like this but
dont know if it is done in the 1.2.x stream
Send in a patch if you like and attach it to a jira issue
2007/12/4, Seldon, Richard [EMAIL PROTECTED]:
Working with Wicket 1.2.6. Having trouble with the implementation of
Component toString() - it has been implemented by wicket framework to
use an overloaded 'detailed' version that contains the following:
.append((isRenderAllowed() isVisible())
The repercussions of this is that where component.toString() is called
from within an overridden instance of component isVisible() method we
get ourselves into a recursive loop. Eventually, this leads to a
java.lang.StackOverflowError with varying results depending on app
server. In IBM Websphere version 6.0.2.2 it actually crashes the server
altogether.
Unfortunately, the wicket framework itself unwittingly corroborates in
this situation arising. A contrived example code and scenario where this
can occur is in wicket.model.AbstractDetachableModel :-
public final Object getObject(final Component component)
{
attach();
try
{
return onGetObject(component);
}
catch (RuntimeException e)
{
throw new WicketRuntimeException(unable to get
object, model: + this
+ , called with component +
component, e);
}
}
Above the WicketRuntimeException message string calls the
component.toString() method. Below is an overridden isVisible()
implementation (from within MyPage component) where a PropertyModel
fails to find the appropriate getXXX for the expression XXX leading to a
WicketRuntimeException in wicket.util.lang.PropertyResolver. For
instance:-
final PropertyModel model = new PropertyModel(this,
incorrectNameOfListGetMethod);
Panel myPanel = new MyPanel(myPanel) {
public boolean isVisible() {
return
((List)model.getObject(this)).size() 0;
}
};

Is there some way we can work easily around this sort of issue? Eg. A
hook in the framework etc to create our own versions of components (with
overridden implementaiton of toString() via a factory? Would rather
avoid patching the wicket jar if possible. Thanks in advance for any
help.

Re: Wicket 1.3 rc1 Relative URLs not working properly
But a mapping shouldnt matter to much. With the filter there should be no need for a filter mapping like a servlet. Johan 2007/12/4, Oliver Lieven [EMAIL PROTECTED]: Hi, I encountered this problem a week ago, too, and digged a little into code and forum. Here's my summary: the problem seems to be the /* filter mapping. If you specify a /app/* filter mapping, relative URLs work just fine. In my base-page-class (all my pages are derived from it through Wicket's great markup inheritance) my stylesheet is referenced in the head-section by a relative reference like link rel=stylesheet type=text/css href=style/myapp.css / Checking the generated HTML in the browser (when using /* filter mapping) shows that this reference is modified by Wicket, so that it now reads link rel=stylesheet type=text/css href=../style/myapp.css / This is an invalid path and addresses a wrong location. I digged into the code and found that relative stylesheet and image references where automatically prepended by ../ by ServletWebRequest.getRelativePathPrefixToContextRoot(). This seems to work well for the /app/* filter mapping, but fails for /* (since theres no parent-directory in between to skip) I currently decided to use the /app/* filter mapping. Following workarounds came into my mind: 1. use of absolute references like /myapp/style/myapp.css. pro: works, Wicket doesn't modify the absolute paths cons: must code the context-path into all style and image references, which is a NO GO 2. use of /app/* filter mapping pro : works cons: after having seen the much nicer /* mapping I want to use it :-)) 3. in HTML it is possible to add a base href=http://localhost:8080/myapp// line into the head section, which is used to resolve all relative references pro : would be great, since it allows the use of relative URLs, and it must be configured in just one place (the base-page's head section) would also be great to use when using a front end server (Apache), since references would be resolved to root context cons: since Wicket isn't aware of the base tag, relative references are still modified and prepended by ../, so no stylesheets/images were found 4. fix it :-)) Related threads and infos: - is it a bug - use of /* filter mapping - http://www.nabble.com/is-it-a-bug--%28using-beta-4%29-tf4649929.html#a13284326 - Wicket behind a frontend proxy - http://www.nabble.com/Wicket-behind-a-front-end-proxy-t4776982.html - http://cwiki.apache.org/WICKET/best-practices-and-gotchas.html#BestPracticesandGotchas-WicketServletMapping Jeremy Levy-3 wrote: WICKET-1205 On Dec 3, 2007 5:16 PM, Jeremy Levy [EMAIL PROTECTED] wrote: Sorry for now explaining this properly.

Re: How to dynamically generate HTML page?
thanks Johan for your reply. I did take look into your slides.
We can generate HTML pages, we have no issue with it. But how to display
this newly created HTML pages which only exists in memory, there is no
physical file. And also to navigate to this new HTML page.
For example If I create a simple HTML page at runtime like below test.html.
How to display it and navigate to it. As it also requires corresponding
test.java. This is simple one. But what if we have wicket:Ids we need
construct the Java files with all the action listener also.
test.html
html

html

How to create the webpage(html) on the fly
Hi,
I am new to wicket.
I am working on a small scenario, where in I am trying to change the
contents of an html page and navigating to that page while the application
is running.
The code is as follows .
My first page is Demo.html, in which I am adding a simple link element.
html
body
div Message goes here /div
Just testbr
Test page
/body
/html
In Demo.java, inside the onclick() event of the 'link' I am trying to add
content to a html file called ShowEnty.html with a component and
initializing the corresponding ShowEnty.java.
public class Demo extends WebPage
{
File outputFile = new File(C:\\web\\pages\\ShowEntry.html);
public Demo()
{
IModel messageModel = new Model(Hello World!);
final String compName = msgInputForm;
Link link = new Link(link) {
public void onClick() {
ShowEntry showEntry = new ShowEntry(compName);
try{
FileWriter out = new FileWriter(outputFile);
out.append(htmlform wicket:id=+compName+input type=\text\
wicket:id=\messageInput\/input type=\submit\
value=\update\//form/html);
out.close();
}catch(IOException iox){iox.printStackTrace();}
setResponsePage(showEntry);
}
};
add(link);
Label message = new Label(message, messageModel);
link.add(message);
}
Now the ShowEntry.html looks like the following code with a form, having a
input text field and a submit button (as the contents I was adding from the
onclick() method in the above Demo.java)...
html
form wicket:id=msgInputForm
input type=text wicket:id=messageInput/
input type=submit value=update/
/form
/html
Similarly the ShowEntry.java is as follows
public class ShowEntry extends WebPage{
public ShowEntry(String component) {
IModel messageModel = new Model(Hello World!);
add(new MessageForm(component, messageModel));
}
private final class MessageForm extends Form
{
public MessageForm(String id, IModel model)
{
super(id);
add(new TextField(messageInput, model));
}
protected void onSubmit()
{
System.out.println(inside submit);
}
}
}
My problem now is, as I was writing the html text into the file, I need to
wait to see the contents or probably restart my tomacat.
Is there any way that we can write this html content to the in-memory file
to have the immediate effect instead of writing it to a file on the disk.

Re: Template Page and the URLs
Hey I managed to answer my own question. Sweet.
If you change the Change Ad link component to an AjaxLink and then
implement this onClick instead you don't end up with a non-bookmarkable url
where once you had one.
public void onClick(AjaxRequestTarget target) {
if (currentBanner.getClass() == Banner1.class)
{
currentBanner = new Banner2(ad);
currentBanner.setOutputMarkupId(true);
TemplatePage.this.replace(currentBanner);
}
else
{
currentBanner = new Banner1(ad);
currentBanner.setOutputMarkupId(true);
TemplatePage.this.replace(currentBanner);
}
target.addComponent (currentBanner);
}
However is the non-Ajax link behaviour expected upon a Panel change within
the page? Since the page was obtained via a bookmarkable link do I HAVE to
use an AjaxLink if I want it to remain with a bookmarkable URL?
Cheers
Nick

Re: Problem with 1.3 Validation and Conversion order
yes. that is why our validation is more then just validators
validate() {
validateRequired();
convertInput();
validateValidators();
}
this also has the advantage that type conversion is only performed once

IComponentResolver question. Was: How to dynamically generate HTML page?
I was looking at the code of AutoComponentPanel and found similarities
between this and IComponentResolver. AutoComponentPanel has an
overridable getMarkupComponent(ComponentTag, MarkupStream) where
IComponentResolver has resolve(MarkupContainer, MarkupStream,
ComponentTag). Can someone explain this class and its uses to me? Is it
something that I should want to use for AutoComponentPanel?
We user AutoComponentPanel as a base class for some other panels that
provide dynamic markup. Would it be better (aka the wicket-way (tm))
when AutoComponentPanel is re-written as an IComponentResolver that can
be used by the currently subclassing panels. They would then need to
implement IComponentResolver too but can call my rewritten
AutoComponentPanelAsResolverSomething in their implementing methods.
Would this be a better way to go?
How should this work when I add my resolver with
Application.getPageSettings().addComponentResolver(resolver)?
Thanks,

Hello Praveen,
Wouter Huijnink presented something similar to what you need at the
wicket meetup in Amsterdam. We generate html dynamically from xml,
using xslt. A component called AutoComponentPanel parses the html and
adds components to the hierarchy accordingly. This is actually a
two-step process. The first step is telling wicket you want to supply
markup yourself instead of letting wicket read it from the
corresponding html file. You can do this by implementing
IMarkupResourceStreamProvider and if applicable also
IMarkupCacheKeyProvider. Then you need to parse the markup stream and
add components.
If you're interested I can send the AutoComponentPanel code. It still
needs some work to make it shine, but we plan to open source it anyway
as part of a wicket-based QTI framework.
PS. Unfortunately Wouter's slides aren't uploaded yet.
