Right, it doesn't matter from the serialisation point of 
view, but if you replace the component in the component 
hierarchy, you should make sure that you also update these
references to point to the new component instances. 

That's why I prefer accessing child components dynamically
whenever it can be easily done.

You have to do the submit to get the desired username to
server for checking, and then react accordingly. You could
make uniqueness check a validator and then models do not
get updated if the username is not unique.

Servlet context temporary directory, which can be something

some Wicket setting or by providing a custom pagestore).

AjaxFallbackButton and setDefaultFormProcessing(false)

2008-11-03 Thread jpswain


I'm building a registration page for my wicket app, and I'm having trouble
getting an AjaxFallbackButton to work the way I would like it to.  I have
several fields for the user to fill out on my registration page, including
email, password, desired-username, etc.

What I want is to have an AjaxFallbackButton next to desired-username to see
if it is available and then display a label saying whether it is or isn't
available.  This works fine when AjaxFallbackButton's
setDefaultFormProcessing is set to true (as by default).  However, this runs
the onSubmit() of the form, not just the onSubmit() of the button itself as
I want it to.

If I do ajaxFallbackButton.setDefaultFormProcessing(false) then it gets
nothing from the model.


When I have used non-Ajax buttons in the past with Wicket, I called
textField.updateModel() and then called textField.getModelObject(), which
made it possible to retrieve values with defaultFormProcessing set to false
and therefore did not run the form's onSubmit() method.  However when I do
this with AjaxFallbackButton I get a null pointer execption :(.


If this is too incomprehensible, I can try to make a quickstart
demonstrating the problem.  I'm really not sure what appropriate behavior
with these forms/buttons is to begin with though, so I would really
appreciate help.  I have pasted my class which may help.

Thanks!
Jamie

Feedback/Error message.

2008-11-03 Thread Graeme Knight


Hi.

Loving Wicket so far! I had a search and had trouble finding the answer to
this one, if anyone can help:

1) I have a simple form with username/password and a submit button.

2) User enters username/password and hits submit.

3) onSubmit authenticates against the database through a load on a
LoadableDetachableModel, and returns the result as the model's object.

Let's say there is an error on authenticating against the database - what is
the easiest way of giving the user feedback that his username/password was
wrong? I naively thought I might be able to do some sort of conditional
insert of a component into the page or form (similar to Tapestry).

My solution was then to add a panel (regular not feedback) to the page which
consists of an error icon and a custom message. I would like to update this
component on the re-render so it doesn't display if there isn't a problem,
but it does if there is a problem (couldn't get isVisible working this way). 

What's the Wicket way?

Many thanks, Graeme.

Hey guys,

I've been working with Wicket using Ant for the last year with no big
problems.  However, I am now trying to get maven working so I can build a

Anyways, sorry for the extremely long post, but maven is just driving me

I very much appreciate any help you guys can offer.  The Wicket community is

yes, when using the diskstore only the current page is in httpsession.
the other pages are only needed if the user uses the back button.

standard http session replication. when a node receives a page from
another node via session replication it adds it to its own local
diskstore.

 Thanks for your answers - so you think its better NOT to have the
 components as private member variables? I may misunderstand...

 'Tapestry' in Action LOL! Sorry! I'm moving over from that world
 into
 the Wicket world...

 Wicket in Action - VERY readable and well written, but perhaps I didn't
 get far enough along to get to the serialization parts (I'm just
 beginning
 Part 2).

 Cheers, Graeme.

Re: Issue with nested forms

the whole point of a transparent container is that they are
transparent, so your subclasses can add items directly to the page.

Re: Issue with nested forms

2008-11-03 Thread Andrew Berman

So even if I do this, all child pages need to add their components to the
body and not the direct page itself which to me doesn't seem right.  Is
there a way to get around this or is there a better way to add a dynamic
class to the body tag?

Re: How does serialization work?

2008-11-03 Thread Graeme Knight


Thanks Igor! A great help! 

Where on disk are these serialized pages? I remember reading you only cache
the current page in memory. Is that correct? This serializing on disk - what
is the strategy for keeping these files in sync in a clustered environment?

Appreciate the help very much! Graeme.

 I find it easiest to start from Session.requestDetached().
 There you have

   page.getPageMap().put(page);

   =>

   SecondLevelCacheSessionStore.put(Page)

   =>

   DiskPageStore.storePage(String sessionId, Page page)

 and there's already stuff about serialisation.

 I'm sure that someone can give you a more scientific answer :)

 In here

 you add them as children of the constructed component.
 You can always access them for example with a visitor, if
 needed, and holding references to them makes it harder to
 replace them if needed (though it shouldn't be a problem if
 they won't be replaced).

 Best wishes,
 Timo

Re: How does serialization work?

as far as serialization wicket uses default java serialization with a
few tweaks to optimize it.

> Thanks for your answers - so you think its better NOT to have the components
> as private member variables? I may misunderstand...

it doesnt matter if you do this. because the page object is serialized
and those components are fields of the page they are serialized only
once and further references are replaced with links, this is how
serialization works and it preserves proper references.

yes, you are missing a very fundmental point about models and the
reason for your lazy init exception is that you are using Model. there
are quiet a lot of threads on this list that explain and show how to
fix your error. i suggest you search the archives, read the models

Hi.

I wondered another thing - how and when are the serialized objects cleaned
up? Is there a mechanism for making sure large amounts of memory or disk are
not soaked up by long running sessions and lots of user interactions?

Thanks again, Graeme.

Timo!

Thanks for your answers - so you think its better NOT to have the components
as private member variables? I may misunderstand...

'Tapestry' in Action LOL! Sorry! I'm moving over from that world into
the Wicket world... 

Wicket in Action - VERY readable and well written, but perhaps I didn't get
far enough along to get to the serialization parts (I'm just beginning Part
2).

I find it easiest to start from Session.requestDetached().
There you have

  page.getPageMap().put(page);

  =>

  SecondLevelCacheSessionStore.put(Page)

  =>

  DiskPageStore.storePage(String sessionId, Page page)

and there's already stuff about serialisation.

I'm sure that someone can give you a more scientific answer :)

you add them as children of the constructed component. 
You can always access them for example with a visitor, if 
needed, and holding references to them makes it harder to 
replace them if needed (though it shouldn't be a problem if 
they won't be replaced).

How does serialization work?

2008-11-03 Thread GK1971


Hi!

Again, I'm new, so hopefully I'm not posting in a bad way here. I've looked
through the forum but couldn't find the answer. Couldn't find the answers
from Tapestry in Action (I'm sure they are there if anyone can point me at a
page).

I have a simple page and form as below. The AuthenticationModel is a
LoadableDetatchableModel that queries the database for a username/password
based on a cookie id (I've cut all this code out for the example below).

My questions are perhaps super naive, but for some reason I am panicking
about serialized objects:

1) Exactly WHAT is getting serialized and where and when?

2) What are the main classes in the framework responsible for serialization
that I can look at (I have the source)? I guess I am after understanding the
flow of logic.

3) What happens if I make userIdField and passwordField scoped to the
constructor only? Is it common not to have them as member objects and why?
(I've not tried this yet, just wondered).

Many thanks for any help once again...

public class LoginPage extends AbstractWebPage
{
public LoginPage()
{
// create a login form and add it to the page
add( new LoginForm() );
}   
}

public class LoginForm extends Form
{
private static final long serialVersionUID = 3975327499669581927L;

private TextField userIdField;

private PasswordTextField passwordField;

public LoginForm()
{
super( "loginForm", new AuthenticationModel() );

userIdField = new TextField( "username", new PropertyModel(
authenticationModel, "username" ) );

passwordField = new PasswordTextField( "password", new
PropertyModel( authenticationModel, "password" ) );

 
// add the components to the form
add( userIdField );
add( passwordField );
}

@Override
protected void onSubmit()
{
// authenticate user
}
}

Re: Wicket + spring + jpa/ hibernate = lazy load exception


James, thanks for your reply. I've checked that my
OpenEntityManagerInViewFilter precedes the Wicket filter. And my debug log
indeed shows that it seems to be opening and closing the entity manager
before and after the wicket filter runs. I'm hoping to avoid the type of
query you suggest, but I'm realizing I may need to resort to it.

Re: Wicket + spring + jpa/ hibernate = lazy load exception


Igor,

I'm not using a loadable detachable model because I was hoping to get the
list of foos directly from the Bar object, as opposed to having a dedicated
dao method to get the list of foos, which seems to defeat the benefit of
using JPA's object chaining. To answer your question, here's my
implementation of dataprovider#model():

public IModel model(Object object)
{
return new Model((Serializable) object);
}

Of course, it's very possible I'm missing a fundamental point about loadable
detachable models...

Re: Should/Could ServletWebRequest.isAjax be cached?

OK, it doesn't look like it's that then.

Look at where IMarkupSettings.getMarkupCache() is being 
called. It seems that whenever a MarkupContainer is looking 
for its associated markup, it's using the markup cache, 
which in turn returns Markup objects that are already 
parsed markup.

It would be good if you could provide a minimal quickstart 
on which you can reproduce this. Also, 2000+ rows in a table 
on a web page does not sound like very handy to me :)

Me neither, but luckily it's open source :)

Re: Handling exceptions during render


Can you be more specific? What kind of unexpected runtime exceptions are you
talking about? I don't think I understood you correctly. 

Any runtime exception thrown by the wicket is caused by a programming
error... there is no sense to catch it without fixing the problem in your
code. 
Catching runtime exception could make sense if the runtime exception is
thrown by some business logic you are invoking inside wicket components
but this kind of issue is your responsibility..

Something like 

Form form = (Form) tester.getLastRenderedPage().visitChildren(Form.class, new 
Component.IVisitor() {
public Object component(Component component) {
return component;
});
FormTester = tester.newFormTester(form);

In jdave-wicket you have this bundled in and can do just

Form form = selectFirst(Form.class).from(context);

If there are more than one Form visible on the page, you have
to differentiate a bit more in the visitor and it gets more 
messy.

Re: Losing session information

a couple of things to look into:

access to Session is not synchronized, so make sure you sync
everything yourself.

if you have a stateless page it will not store the session in
httpsession, you might have to do that manually by calling
session.bind()

QueryStringUrlCodingStrategy question

2008-11-03 Thread jchappelle


I have the following code:

PageParameters parms = new PageParameters();
parms.put("answerId", Long.toString(answer.getEntityId()));
add(new BookmarkablePageLink("edit", EditBlogEntryPage.class, 
parms));

In my Application init method I have: 

mount(new QueryStringUrlCodingStrategy("answerdetails",
EditBlogEntryPage.class));

When I click the edit link to get to my page my URL looks like:

http://localhost/robojot/answerdetails/?x=SvX0Lakly72TaK8AnLyL*A

Can someone tell me why it doesn't look like the following:
/answerdetails?answerId=123

Thanks

Re: Wicket + spring + jpa/ hibernate = lazy load exception

2008-11-03 Thread James Perry

Firstly, your code is rather strange. That getFoos() method is not part of
the List Interface API.

Two possible solutions:

The filter chain maybe incorrect in your web.xml. Your
OpenEntityManagerInViewFilter might not be preceding the Wicket filter.
Check that it does precede it.

If you have a deadline then I recommend having one query that retrieving
both foos and bars in one hit. I've never touched JPQL but in Hibernate
Query Language (HQL), one could write this:

"select f from Foo f inner join fetch f.boo b where b.id = :id"

Good luck,
James.

Re: Wicket + spring + jpa/ hibernate = lazy load exception


Oops...I meant:

Bar bar = myApi.getBar();
List foos = bar.getFoos();

Losing session information

2008-11-03 Thread Dane Laverty

My site has a form-based test on TestPage. Each question in the test has
a Question object as its model. The Questions all sit in an ArrayList in
a Test object. Each Question has a "markedAnswer" String, which stores
the value of the selected answer. The problem is that, for some users,
the "markedAnswer" fields are become null on the TestResultsPage after
the test is submitted. This behavior is not consistent (I haven't been
able to replicate it) but it happens dozens of times daily, so I know
that it's a real problem.

 

My question is, does anyone have any ideas why
session.user.test.questions[i].markedAnswer becomes null for some users
after they submit the test? 

 

Here's the relevant code. Important lines include:

- TestPage, line 37. This inserts the test results into the database.
Because this is happening correctly, I know that user.test.questions is
still populated at this point.

- TestResultsPage, line 12. This is where question.getMarkedAnswer()is
null (and throws a NullPointerException).

 

1  public class TestPage extends...

2  {  

3private User user;

4 

5public TestPage()

6{

7 user = getSession().getUser();

8add(new TestForm("testForm"));  

9}

10

11final class TestForm extends ApplicationForm

12{   

13  public TestForm(final String id) {

14super(id);

15

16add(new ListView("questions", new PropertyModel(user,
"test.questions")) {

17  

18  protected void populateItem(ListItem item) {

19final Question question = (Question)
item.getModelObject();

20

21// answersRadioGroup will be a group of radio
buttons -- one for each possible answer (4, currently)

22RadioGroup answersRadioGroup = new
RadioGroup("answers", new PropertyModel(question,
"markedAnswerLetter"));

23

24// This loop will generate a radio button for
letters A, B, C, and D. Those letter are hard-coded

25// into the database as answer selections, so
we can't change them.

26for (char letter = 'A'; letter <= 'D';
letter++) {

27Radio radio = new Radio(letter + "", new
Model(letter + ""));

28answersRadioGroup.add(radio); 

29}

30

31item.add(answersRadioGroup);

32}

33});

34  }

35  

36  protected void onSubmit() {

37fhBD.uploadUserTestResults(user); 

38setResponsePage(TestResultsPage.class);   

39  }

40}

41 }

 

 

 

1  public class TestResultsPage extends...

2  {

3 private User user = getSession().getUser();

4 

5  public TestResultsPage()

6  {

7   add(new ListView("resultsListView",
user.getTest().getQuestions()) {

8 

9 protected void populateItem(ListItem item) {

10  final Question question = (Question)
item.getModelObject();

11  

12  Label answerText = new Label("answerText", new
Model(question.getMarkedAnswer().toString()));

13  answerText.setEscapeModelStrings(false);

14  item.add(answerText);

15  

16  }

17  });

18 }

Wicket + spring + jpa/ hibernate = lazy load exception


I am experiencing exactly the problem outlined in the subject of this post,
and I would really appreciate any help I can get, as I am under a deadline.
It's the first time I'm using Wicket with JPA, and I just don't understand
why this isn't working. 

I have a Wicket dataprovider that looks like this (I've simplified it a
bit):

public abstract class FooDataProvider extends SortableDataProvider
{
private static final long serialVersionUID = 1L;

@SpringBean
protected MyAPI myApi;

public FooDataProvider()
{
super();
// Injects the spring bean
InjectorHolder.getInjector().inject(this); 
}

public Iterator iterator(final int first, final int count)
{
List bars = myApi.getBars();
List foos = bars.getFoos();
return foos.iterator();
}
}

I am using a very standard Spring JPA setup, and my web.xml includes a
OpenEntityManagerInViewFilter. The spring bean is being injected properly,
and my list of Bar is returned correctly. But I get a
LazyInitializationException no matter what I try. What am I doing wrong?

Many thanks,
Julian

Re: Add AJAX behaviour to embedded custom form component

a better way is to have a factory method for the internal components,
that way the user can do

component newcomponent(string id, imodel model) {
  component c=super.newcomponent(id, model);
  c.add(whateverbehavior);
  return c;
}

Re: Referencing Request in Spring bean definitions

you need to create a provider, eg:

interface requestprovider { request getrequest(); }

and class requestproviderimpl { request getrequest() { return
requestcycle.get().getrequest(); }}

then inject your beans with the requestprovider.

Re: Referencing Request in Spring bean definitions


Creation of custom sessions is described here:
http://cwiki.apache.org/WICKET/newuserguide.html#Newuserguide-CustomSessions

I do think you can create a session through Spring.

Re: example application for spring wicket hibernate

Hi Miro,

Did you receive my Wicket+Spring(via annotations) sample  application ? Any
feedback welcome :)

I can also provide a sample application with Wicket+Spring(via
annotations)+Hibernate(via annotations) that does nothing except showing a
way to configure the three to work together.
( I only have a big application using the three that I can't distribute,
but I planned to built this week a very light sample to reuse for other
projects ... ).
Just ask If you're interested.

Anyway the phonebook is a good way to start ;)

Re: How to plant dynamic data to the html

from the java code according to the url  I get from the user.

  The problem happens with you configure the filter to use url-pattern = 
 "/*".
  If you change to something else, like "/x/*" the redirect will work as 
 expected!

Re: Incremental migration from JSP-based applications to Wicket?

2008-11-03 Thread Martin Grigorov

Hi Susan,

I'm in the same situation. With the only difference I have few months
advance.
And I'd say the project works very good for now. Currently some of the
pages are backed by Wicket and the rest are still JSP ones and there is
no difference from a customer point of view. 
None of the Wicket pages does include any JSP chunks. They are made
entirely in the Wicket way. So we don't use AlMaw's solution at all. At
the beginning it was slow but now we started to reuse more and more
components and it's getting faster to migrate the next JSP page.

good luck

Re: PageParameters in wicket 1.2.7 problem

Basically, the code that executes is:

public ValidatePage(PageParameters parameters)
{
super("Valideren gegevens");

String code = parameters.getString("code");

If I put a breakpoint right after this, I already get the incorrect
code. The page that I use extends a page that contains the basic
layout/menu from the page, but that page does no redirecting either.

I'm reading up on the session sharing, but from what I can see that is
not recommended because of security issues. I didn't think about using
cookies though, so thanks for that suggestion. That sounds like it would
be the best solution.

Incremental migration from JSP-based applications to Wicket?

2008-11-03 Thread Susan Liebeskind


Hi,

This helpful posting

http://herebebeasties.com/2007-03-01/jsp-and-wicket-sitting-in-a-tree

is often cited as a guide whenever anyone asks about migrating from a 
JSP-based web application to an equivalent JSP-free Wicket application.  


But...

the posting itself is >18 months old and describes work with a 
pre-release version of 1.3. Wicket 1.3.5 is out as of Oct 2008, with 
1.4-M4 just around the corner. I also see that the posting clearly 
states that this is not a boxed solution, or particularly 
well-supported, buyer beware and all that.  Fair enough. So it is with 
low expectations, but with hope for an answer nonetheless :-), that I 
ask the question


"is there a newer/better solution available now for supporting JSPs in 
Wicket 1.3 or the upcoming Wicket 1.4, one which is 
cleaner/easier/addresses gotchas mentioned here. Or is the technique 
referenced here still best practice?"


My guess is that Alistair's technique is still best practice, based on 
newer postings I see on this list, but I'd like to ask the question 
outright, just in case I've missed something.




Some thoughts about migrating a JSP based application to Wicket:

I know that in the long run, one would choose Wicket so as to be JSP 
free.  And certainly there are issues with JSP development as we all 
know.  I would almost say that to some developers,  JSPs are the high 
fructose corn syrup of the web development world, very sweet (in some 
ways), but bad for you in the long haul :-)  

Thing is, going JSP free is a transition if you have a legacy app.  
There's where you are now, there's where you want to be, and a migration 
path which involves some period of time where one would need to support 
both JSP and Wicket pages in the same app.


In the case of our current project, we have some large Struts 1.x based 
applications with many JSPs (nearly 900._ Some JSPs are simple, just 
divs filled in by Ajax components, but other JSPs are complex and use 
scriptlets, inline javascript, 3rd party and custom tags. There's more 
work in recoding these JSPS (extracting the HTML template skeleton from 
the JSPs, recoding the core/3rd party/custom tags from taglibs in Java, 
replacing our simple use of Tiles 1 for page composition again with 
Java, refactoring those scriptlets, calling out to a custom 3rd party 
Ajax toolkit...etc. etc.).


The point is, we cannot simply stop, migrate the whole app over to 
Wicket and bring it back up - a gradual migration is necessary, doing 
JSP migration in bitesize chunks.


My colleague Rich Allen has been posting various questions to the this 
list as we evaluate our replacement for Struts, and after looking at 
Wicket some, I understand why he likes Wicket a lot.  It is a clean 
division of application from presentation, and for a new development 
effort, that would be really cool. But we have a large legacy 
application to support - that's just the way it is.  So a 
straightforward and incremental migration path from existing JSPs to 
Wicket is something that would be critical for our team.


Costs to consider: We have a lot of developers, some experience and some 
newbies, and we have a large code base.  Replacing JSPs is not an 
inexpensive proposition, and we need to do it in small pieces, and 
clearly spell out the approach for our team.  Indeed one argument for 
choosing something like Spring MVC to replace Struts is that Spring MVC 
is another MVC framework that, for better or worse (and I know the 
community on this list would say "for worse" :-) , preserve our 
investment in JSPs.  

Again, if this were a new development, starting with a clean slate, the 
decision inputs are different. But when you have substantial investment 
in JSPs, a valid question is "do we want to pay the cost of retooling 
now vs. later or not at all? Can we simply be disciplined in our use of 
JSPs, but continue to use them nonetheless, because the cost of 
retooling is too high?"  

By choosing Wicket, we would be saying "enough with JSPs", but we have 
to have a cost effective way of incrementally achieving that goal, where 
cost is measured in how easy it is to retrain our developers and to 
migrate in small, manageable pieces.


Any advice/anecdotes are gratefully welcomed.

Thanks in advance.

Susan

Strange, but as you said you had the idea that it could be a bug. But it
still strikes me a bit strange that the page are redirected, and results
in an modifified link.. Could you provide a cut out of the code?

Otherwise the idea with the servlet should be fine, I think you can
enable shared sessions somewhere in tomcat at least... Otherwise you
could do it with an encrypted session cookie..

Yeah, I was afraid it would come to that.
Sorry, you've apparently done some more research already...

Another thing I sometimes do is take the Wicket class and put it in the 
web-project's classpath but with my changes (e.g. remove a final). All 
servlet containers will load earlier from the WEB-INF/classes folder 
then from WEB-INF/lib. Its a huge hack, but it works most of the time.


Regards,
Erik.

Add AJAX behaviour to embedded custom form component

2008-11-03 Thread Gianni Doe

I've developed a custom form component (FormComponentPanel), a date  
picker, that makes use of 2 fields - a display TextField and a  
HiddenField for the model data. I'm then adding this to the page with  
a span tag:

[dropoff date picker]

Then in the java :
DatePicker  dropoffDatePicker = new DatePicker("dropoffDate", new  
PropertyModel(this, "dropoffDate"),
(new LocalDate()).minusDays(0), (new  
LocalDate()).plusYears(3));


I'm after some advice on the best way to attach an AJAX behaviour to  
the component. If for example I add an AJAX behaviour directly to the  
date picker component then it's attached to the span tag and obviously  
doesn't work. The only way I've found to get around this is to expose  
the date display field with a public getter so I can then attach the  
onchange event.


dropoffDatePicker.getDateDisplayField().add(new  
AjaxFormComponentUpdatingBehavior("onchange") {

@Override
protected void onUpdate(AjaxRequestTarget target) {
..
}
});

Any suggestions for a better way to do this that doesn't involve  
exposing the innards?

Re: Handling exceptions during render


If you return null in onRuntimeException -> the stack trace will be shown.
But if you will return a page instance, the application will redirect you to
this page. For instance:
[CODE]
@Override
  public Page onRuntimeException(final Page page, final RuntimeException
e) {
  //do something
  return new LoginPage();
  }
[/CODE]

The above example will redirect you to the LoginPage if any runtime
exception occures.

Re: Handling exceptions during render


It won't. I think you have to dig deeper into the request rendering.

Perhaps that overriding MarkupContainer#renderAll on all your Panels 
that have expected exceptions will help.


But then again, exceptions are intended for controlling the 
non-expected. You should not use exceptions for normal page flow. In 
other words: just make sure that no exceptions are thrown.

   Erik.

In order to catch all runtime exception, you have to override default
RequestCycle (newRequestCycle method) in your application class and
override onRuntimeException method.

Example:
[CODE]

public RequestCycle newRequestCycle(final Request request, final Response
response) {
return new WebRequestCycle(this, (WebRequest) request,  (WebResponse)

  @Override
  public Page onRuntimeException(final Page page, final

Re: PageParameters in wicket 1.2.7 problem

2008-11-03 Thread Rik Overvelde

Hi Nino,

I don't link to the verification page from inside the application
itself. Instead, the link is send in an email to the user when he
changes his email adress. When they click the link, the page is opened.
In a lot of cases the users are still logged in on the application,
meaning that a second tab is opened. If that is the case, the url
changes in the way that I described. If there is no other tab with the
application open when the user clicks the link, the page works fine
(meaning that the page parameters are being read). Also, when the bug
occurs it triggers an error message which tells that the given code is
incorrect, which means that the page parameters are read at that point
as well.

Hi Rik

Im not sure about this, it's been some months(if not years) since i've

instead just instantiate the page with an other constructor..

Hey everyone,

I'm having a problem with page parameters in wicket 1.2.7 when

email adresses, which sends a mail with an url containing a guid to a

which results in an address like:
http://page.com/verificatie?code=0572f18d-a9b1-4b92-bb89-7243b9e35d24.
When the link is opened while you're already logged in though, wicket
changes the url while loading in something like this:
http://page.com/verificatie?code=%5BLjava.lang.String%3B%4087bf0b&wicket:pageMapName=wicket-0

From what I understand, this is a known issue with wicket 1.2 and is
solved in wicket 1.3. The application I'm working on however is
already fairly large and because of time constraints it is impossible
right now to migrate to 1.3 so I'm looking for a workaround for this.

One thing that I've been thinking about is to have the verification
link point you to a non wicket servlet, which writes the guid to its
session, then forwards you to a wicket page that retrieves the guid
from the other servlets session. Is there a way to get the other
servlets session in wicket?

If anyone has another suggestions for getting around this problem I'd
love to hear it.

There are more threads about this issue... 

In order to catch all runtime exception, you have to override default

Try doing wicketTester.debugComponentTrees() (or debugging the exact

FormTester f =

Long component paths like this are a bit problematic anyway.
You could try digging your Form up with a visitor to make it

Handling exceptions during render


Hi, how can I catch any exception thrown while a component is rendering, and
either hide the component or show an error message, but allow the rest of
the page to render?
Modifying or replacing each such component is not an option, I need a
general way to handle exceptions while rendering any unknown component or
child component. Such as a getObject method from a model throwing a runtime
exception.

This problem happens with tomcat (6.0.16, 6.0.18) when you have a

(netbeans default web project).

I will try to investigate more before open a bug...

Re: Repeater with checkbox

2008-11-03 Thread Hannes Schubert


Jurrie,

this goes very well. I use check boxes in repeaters for the same reason. 
Just have a look at the following snippets.



   dynamicContents.add(listView = new DataView("whatever", 
getDataProvider(), 15)

   {
   @Override
   protected void populateItem(Item listItem) {
   final Whatever whatever = 
(Whatever)listItem.getModelObject();


   //log.debug("populateItem() 
whatever="+whatever.getControlnumber()+" => 
"+selection.contains(whatever.getId()));
   final SelectionModel selectionModel = new 
SelectionModel(whatever, selection.contains(whatever.getId()));
   final CheckBox checkBox = new AjaxCheckBox("selected", 
selectionModel) {

   @Override
   public void onUpdate(AjaxRequestTarget target) {
   Boolean selected = selectionModel.getObject();
   Long id = selectionModel.getSelection().getId();
   if (selected)
   selection.add(id);
   else
   selection.remove(id);
  
   log.debug("selected.onUpdate: "+selected+" for 
id="+id);

   }
   };
   checkBox.setOutputMarkupId(true);
   checkBox.setVisible(selectionEnabled);
  
   selectionBoxes.put(selectionModel, checkBox);
  
   listItem.add(checkBox);   
  
   listItem.add(new Label("dmcControlnumber", new 
PropertyModel(whatever, "controlnumber")));

...

This requires a simple class what simply reflects the selection state of 
the selected/unselected rows collected in a map. It is a bit tricky if 
you start up with some rows already selected and dataproviders 
supporting lazy loads . Then you might have to setup the selection 
models on creation only for visible rows and merge afterwards.


Best regards
Hannes

Are you running in deployment or development mode?  I would try your
profiling in deployment mode to see how that helps.

Repeater with checkbox

2008-11-03 Thread Jurrie Overgoor


Hello everyone,

I'm currently creating a Wicket application, and for this I need a 
repeater that lets the user select multiple rows from a list of items. 
So basically a repeater that adds a checkbox in front of every item. Is 
this component available? I remember seeing this somewhere, but I forgot 
where, and I can't seem to find it again.
