Re: Dynamic Generation of wicket Screen

Hi!

You can always use:

field = new Field(...) {
   @Override
   public boolean isVisible() {
   return showIfVisible;
   }
}

Re: Dynamic Generation of wicket Screen

[sravang]

Thank u for your reply.

I will explain my work. if have any idea pls let me know.

My screen have one TextField name is like Customer.

That customer's name come from DB through search option.

Based on the customer screen will display field-wise(some fields display for
some customer and some fields disable for some customer based on the fields
stored in DB)

Awaiting for your reply.

Thanks,
Sravang.

Dynamic Generation of wicket Screen

Hi, Any one have idea about Dynamic Generation of wicket Screen depends on
value Stored on Database?

FeedbackPanel for Dynamic Form

[Brad Grier]

I've written a dynamic form engine which does its work using a ListView and 
Fragment subclasses representing the various form fields. Everything works 
great including saving and retrieving form information. Now that the fun is 
over, I've run into a problem adding validation. In the markup for the fragment 
subclasses, the wicket:id is always "field". That's okay...until I try to add a 
FeebackPanel to the form to report validation errors. Since the identifier for 
every form field is the same, the messages displayed in the panel are useless. 
Any advice?

Thanks,
Brad

Re: wiQuery components with server side state - live demo

[Early Morning]

These look really great Cemal, thanks for sharing. I'm looking forward to
trying them out, as they seem really useful :)

As an aside, regarding storing component position/settings as mentioned by
Vladimir, does anyone have any resources/advice how to best do that for a
multi-user system where users can save their personal preferences? I was
thinking of doing an ajax call whenever the sorting is changed in order to
store the settings in a DB, but that may have too much overhead. Storing
data client side would still have the problem of how to synchronize the data
on the server side. Is there a recommended way to do this? Thanks!

Ces

You would instantiate your FeedbackPanel with an IFeedbackMessageFilter:

Perhaps you would check to see if the form itself is the "reporter" of

Extended Form Question

[Josh Chappelle]

Hi, 

 

I have extended the Form component to include a visitor that adds some
behaviors to required fields so that the validation errors are rendered next
to the corresponding fields. My problem is that I have a form that has a
form level validator that is not specific to a component. So I still need a
feedback panel to be included. My problem is that the feedback panel also
lists all of the component's individual errors.

 

How can I make my feedback panel not filter out form level messages but
filter out component level messages?

 

Thanks,

 

Josh

Wow, this is fantastic. Wish I'd had it 4 months ago before I had to start

We'll pick it up for our next project if possible, its exactly what we need.

Nice stuff guys.

Re: wiQuery components with server side state - live demo

[Vladimir K]

Looks great!

One thing is missing - the components don't restore their state on refresh.
I believe cookie, window name or dom storage can be used to keep the
position and settings of components that are available for
dragging/re-arrangement.

Bookmarkable root page with PageParameters

[Anthony DePalma]

I added a bookmarkablePagingNavigator to my page to enhance seo, and
when the homepage was bound to the context '/stories', it worked very
well (http://www.luckeffect.com/stories/page/1). However I wanted to
remove the stories context so the homepage was bound directly to the
root, and now it seems all my bookmarkable urls are session based like
so: http://www.luckeffect.com/?x=b8xFzszfimM.

Is there anyway to achieve the bookmarkable functionality with the
root context? For example, http://www.luckeffect.com/?page=1.

What have you tried thus far to change the label? Another approach

Re: [newbie] Wicket, Spring, Hibernate and transactions in views.

[James Carman]

Introduce AspectJ and spring-aspects into your build.  You can see an
example of it in my wicket-advanced sample project:

http://svn.carmanconsulting.com/public/wicket-advanced/trunk/

Then, AspectJ will weave the transaction support into your
Page/Component classes like you want.  There are limits on what type
of methods can be transactional, though.  I would also recommend the
OpenSessionInView filter (which my example project also uses).

Thats exactly what I am using, but it doesn't seem to work.

I've set up as per the original posts tutorial (that includes
OpenSessionInViewFilter).

The log below show me calling it - and supposedly opening the
transaction (although it does do everything twice);

Re: [newbie] Wicket, Spring, Hibernate and transactions in views.

[Pedro Santos]

Consider to use OpenSessionInViewFilter

http://static.springsource.org/spring/docs/1.2.9/api/org/springframework/orm/hibernate3/support/OpenSessionInViewFilter.html

The doc: "Intended for the "Open Session in View" pattern, i.e. to allow for
lazy loading in web views despite the original transactions already being
completed."

Wicket button label

[Metzger, Natalie J.]

Hi all,

I'm comparatively new to Wicket and have a question about the wizard button 
labels. I'm using a Wizard with an AjaxButtonBar and AjaxButtons for previous 
and next. I would like to change the labels on the last step of the wizard of 
the cancel and finish buttons. I know how to change those labels for the whole 
wizard, but it escapes me how do change them in the last step only. Is there 
any elegant solution to this?

Thanks,
Natalie

[Colin Rogers]

" I'm not DB expert, but why are you using transactions for "read only"
(SELECTs) queries?"

"If you aren't concerned with "good design" then I wouldn't worry about
transactions at all"

Because you need the transactions for lazy fetching of child elements in
hibernate.

wiQuery components with server side state - live demo

[Cemal A Bayramoglu]

We've been building a few wiQuery components [0], for clients' and
internal projects. These wiQuery components typically maintain some of
their state server-side, in the spirit of standard Wicket components.

Here's a simple demo [1] to show some of them in action.

Look carefully and you'll find lots of stuff to click on [2]. We could
plan to open up the ones we may [3] if they look useful to you or
you'd like to get involved with design/development/testing.

Re: [newbie] Wicket, Spring, Hibernate and transactions in views.

[Riyad Kalla]

I'm not DB expert, but why are you using transactions for "read only"
(SELECTs) queries? I've only ever seen transactions used to wrap
INSERT/UPDATE/DELETE statements (writes)

RE: [newbie] Wicket, Spring, Hibernate and transactions in views.

[Josh Chappelle]

If you aren't concerned with "good design" then I wouldn't worry about
transactions at all. Especially if you are doing read only data retrieval. 

Once you get the code working the way you want you can always add
transactions later and refactor the code into your service methods. That's
the agile method anyway. :-)

RE: [newbie] Wicket, Spring, Hibernate and transactions in views.

[Colin Rogers]

"I'd recommend you to make your transactional control in your services
and call them from your pages instead of trying to control it in your
view."

I'd agree in terms of "good design", but I'm coding something for myself
- and I'm trying to make it easy and as little time consuming as
possible. So, yes, transactions in the presentation layer is "bad" - but
it's only read-only transactions, so I'm letting myself off! ;)

Having the transactionally controlled service methods, individually
instantiate all child entities by hand is also time consuming and would
potentially harm performance (if the view didn't need the children, for
example).

Actually I think in this particular case Wicket didn't make it 'easy' to do
what I needed to do. It would've been easy and logical if I could change
SharedResources method so it doesn't use class name in the first place.

The second logical option (or maybe even first) would've been
CryptedUrlWebRequestCodingStrategy -- but modifications there for this
purpose appear to be non-trivial.

Modifications I've made to WebRequestCodingStrategy are closer to a dirty
hack -- they depend on internal format used by SharedResources and are doing
a guesswork as to what is FQN and what is not. But at least modifications
there are possible and are minor (not likely to break something else).

RE: DownloadLink problem

[Martin Asenov]

Oh my God!!! The problem was that the button that is supposed to do the export 
was of type submit and it reloads the page, instead of refreshing components. I 
changed to type=button and everything's fine...

As people say - there is no patch for human stupidity...

Thank you all for the help!

Best,
Martin

Thanks Ernesto!

But I want to have the link invisible on startup (because the file's empty). So 
I have this: (doesn't work, but has to)

exportedFileLink = new DownloadLink("exported_file_link", new 
LoadableDetachableModel() {

  private static final long serialVersionUID = 1L;

  @Override
  protected File load() {
return exportedFile;
  }
}, PhonebookExporter.OUTPUT_FILE_NAME) {

  private static final long serialVersionUID = 1L;

  @Override
  public boolean isVisible() {
return exportedFile != null;
  }
};
final WebMarkupContainer exportedFileLinkHolder = new 
WebMarkupContainer("link_holder");
exportedFileLinkHolder.setOutputMarkupId(true);
exportedFileLinkHolder.add(exportedFileLink);

rightForm.add(exportedFileLinkHolder);
rightForm.add(new AjaxButton("export_button") {

  private static final long serialVersionUID = 1L;

  @Override
  protected void onSubmit(AjaxRequestTarget target, Form form) {

PhonebookExporter exporter = getExporter();
exportedFile = exporter.export(uploadFolder);

if (exportedFile == null) {
  error(getString("not_exported"));
} else {
  info(getString("exported"));
}

target.addComponent(exportedFileLinkHolder);
target.addComponent(feed);
  }
  
});

I really start to get pissed off by this one!!! g

Weird. Just try this example:

this.download = new DownloadLink("download", new

 add(update);
}
}

and the HTML






download
Click me to update download




Just place them somewhere and do

new TestDownLoadLink("xxx");

It works for me. First time the download link is disable and when you click
on the AJAX link file is assigned, link is refreshed and you can download
your file;-)

I think the Model you are passing to the constructor refers to the choices
Model. Try using EmployeeDropDownChoice("approvaloficer",new Model(), new

Re: How to encrypt/obfuscate resource reference?

[bgooren]

Good to know I contributed something useful to this thread haha.

The code looks like the stuff I had in mind.

You gotta love Wicket for making it quite easy to do this stuff; Although
the URL encoding/decoding can be quite complex for beginners, but that is
likely to be fixed in the future (I've had a look at Matej's wicket-ng
implementation, and it looks very promising).

[newbie] Wicket, Spring, Hibernate and transactions in views.

[Colin Rogers]

All,

 

I've got a bit of a newbie Wicket question involving Spring, Hibernate
and transactions.

 

The question that I can't seem to find an answer to;

 

Can a view be a created/injected/aop'd like a spring bean so that it
honours @Transactional methods for hibernate?

 

An example;

 

public class HomePage extends WebPage {

 

@SpringBean // this is working fine

private SessionFactory sessionFactory;

  

public HomePage(final PageParameters parameters) {

 

this.init();

  }

  

  @Transactional // this is not working

  public void init() {



Criteria criteria =
sessionFactory.getCurrentSession().createCriteria(MyEntity.class);

List myEntities = criteria.list();

for( MyEntity myEntity : myEntities ) {

  

  // where subEntities is a lazy collection

  for( SubEntity subEntity : myEntity.getSubEntities() )
{



// ...

  }

} 

}

}

 

I've been reading Wicket In Action book, various places on the net and
of course, emails on the subject on this list and this particular
tutorial;

 

http://wicketinaction.com/2009/06/wicketspringhibernate-configuration/

 

And I'm still wondering, is this something that is actually possible? I
could full understand that it wouldn't be - i.e. that the injector only
works for Spring injection dependency and not AOP or anything else. So
you inject your dependencies - and they have transaction support etc.
But that means I'll be having to force fetching of lazily fetched
children from outside the views themselves, which is obviously very
painful. It would be so much easier to have transaction support in the
view itself and not have to delegate.

 

Any help would be greatly appreciated.

 

The error message I'm receiving is;

 

Caused by: org.hibernate.HibernateException: createCriteria is not valid
without active transaction

  at
org.hibernate.context.ThreadLocalSessionContext$TransactionProtectionWra
pper.invoke(ThreadLocalSessionContext.java:338)

CompoundPropertyModel issue

[chinedu efoagui]

hello,

i am added a dropdownchoice to a form. The form's model is set to a
CompoundPropertyModel
as shown below
IModel zaModel=new CompoundPropertyModel(selected);
leaveform.setModel(zaModel);

Now the dropdown shows a list of Employees

EmployeeDropDownChoice approvalofficers=new
EmployeeDropDownChoice("approvaloficer",new Model(""));
leaveform.add(approvalofficers);
Now when I run it gives me error that it can find the getter property
of component "approvaloficer"
Now the thing is the component is
So how do i exclude the component from the CompoundPropertyModel and
still have  it show ?
I thought i could achieve that with by passing an emppty model into
its constructor like new model?
how do i solve this??

If you have that string literally copy-pasted in some Java code somewhere,
you need to double escape the escape chars...

Why do you want to use a UrlValidator? An ip-address is not a URL?
Maybe a pattern validator with

Re: Page Expired

[Riyad Kalla]

Alexander,

Maybe this has to do with the persistence store you are using to make Wicket
work on GAE not actually persisting your pages to a location that they can
be retrieved again? I know by default the DiskStore that Wicket uses won't
work on GAE, so I imagine you plugged something else in -- if you did and
it's just tossing out the previous versions of the pages, that would explain
what you are seeing "no version  of page" errors.

What store do you have configured?

The solution is writing a wicket component that finds the image on-disk and

http://old.nabble.com/forum/Search.jtp?forum=13974&local=y&query=dynamic+image

and
these:
http://old.nabble.com/forum/Search.jtp?query=image+on+disk&local=y&forum=13974&daterange=0&startdate=&enddate=

Your
answer is in there somewhere. The thread recently (3 weeks ago?) about it
was pretty long and someone pasted a complete impl that they were using that
folks said worked great. I just don't recall the class name otherwise I'd
search for it :)

ResourceLink with pagerefresh(update)

[Boydens Joeri (OZ)]

Hello,

 

I've created an ResourceLink wich shows the user a download window for
the PDF resource. 

 

Now I want the page to be refreshed when the user clicks the link so I
can update the page and show the user he clicked this link.  How would I
do this ?

 

Regards

Joeri

 

 

ResourceLink pdfAanvragenLink = new
ResourceLink("pdfAanvragenLink", new
DynamicWebResource(documentVO.getDocumentNaam() + "_" +
documentVO.getDocumentId() + ".pdf") {

 

 /**

  * Aangepast door: C501BBJO op 2-mrt-2010 -

   return 30;

 }

RE: DownloadLink problem

[Martin Asenov]

Thanks Ernesto!

But I want to have the link invisible on startup (because the file's empty). So 
I have this: (doesn't work, but has to)

exportedFileLink = new DownloadLink("exported_file_link", new 
LoadableDetachableModel() {

  private static final long serialVersionUID = 1L;

  @Override
  protected File load() {
return exportedFile;
  }
}, PhonebookExporter.OUTPUT_FILE_NAME) {

  private static final long serialVersionUID = 1L;

  @Override
  public boolean isVisible() {
return exportedFile != null;
  }
};
final WebMarkupContainer exportedFileLinkHolder = new 
WebMarkupContainer("link_holder");
exportedFileLinkHolder.setOutputMarkupId(true);
exportedFileLinkHolder.add(exportedFileLink);

rightForm.add(exportedFileLinkHolder);
rightForm.add(new AjaxButton("export_button") {

  private static final long serialVersionUID = 1L;

  @Override
  protected void onSubmit(AjaxRequestTarget target, Form form) {

PhonebookExporter exporter = getExporter();
exportedFile = exporter.export(uploadFolder);

if (exportedFile == null) {
  error(getString("not_exported"));
} else {
  info(getString("exported"));
}

target.addComponent(exportedFileLinkHolder);
target.addComponent(feed);
  }
  
});

I really start to get pissed off by this one!!! g

Page Expired

[Alexander Monakhov]

Hi, guys.

I've got problem with 'Page Expired' message. I'm developing application
that is worked on GAE.
It has one page with help content. There is two help pages. Help page
contains two separated divs. One div for table of content, second - for
content.
When user clicks on link, page is reloaded with appropriated content. So,
when I load this page first time all works fine. But when I click on any
link,
I get 'Page Expired' message.
I set log level to debug. Here is some messages:

13:46:14,140 DEBUG [org.apache.wicket.Session] - Getting page [path =
3:tabpanel:panel:toc-panel:help.panel.navigation:1:help.panel.link,
versionNumber = 1
13:46:14,141 INFO [org.apache.wicket.Page] - No version manager available to
retrieve requested versionNumber 1
13:46:14,141 INFO [org.apache.wicket.AccessStackPageMap] - Unable to get
version 1 of page [Page class = com.dominity.web2care.wicket.pages.BasePage,

13:46:14,142 DEBUG [org.apache.wicket.RequestCycle] - setting request target
to 
[bookmarkablepagerequesttar...@974813593pageclass=org.apache.wicket.markup.html.pages.pageexpirederrorpage]

So, could you explain me what's wrong with this and what is it about: No
version manager available?

If you'd like I show you source code and markup.

BTW, please, bear in mind, that the same page works fine of GAE SDK without
any page expirations, but on server side I get always Page Expired message.

Best regards, Alexander.

Re: How to encrypt/obfuscate resource reference?

[Sergey Olefir]

I admit I didn't research in-depth what you've suggested, but from the
quoted piece it seems that your suggestion will find all subclasses of
ResourceReference. But to actually test that all resources are properly
mapped, it would be necessary to locate all invocations of the
ResourceReference constructors and scan their parameters. I have hard time
imagining how it could possibly work without resorting to AspectJ (or AOP in
general).

Also the same problem may be relevant for e.g. Image() and possibly other
stuff.

Basically, unless I completely misunderstand what you're suggesting, I don't
really see how such scanning might work.

Re: How to encrypt/obfuscate resource reference?

[Martijn Dashorst]

Take a look at the spring component scanner for an implementation of
how to search the class path. Then it is just a series of
ResourceReference.class.isAssignableFrom(clz) queries and applying
your specific logic.

For example we use the following code to scan for specific patterns in
html files (such as style= attributes in html code, which we consider
illegal—use classes and stylesheets instead).

ResourcePatternResolver, PathMatchingResourcePatternResolver are
classes that comes from Spring.

ResourcePatternResolver resourcePatternResolver = new
PathMatchingResourcePatternResolver();
for (String packageName : getPackageNames())
{
String usePackageName = packageName;
if (!usePackageName.endsWith("."))
usePackageName += ".";
String filePatter =
ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX
+ ClassUtils.convertClassNameToResourcePath(usePackageName)
+ "**/*.html";
try
{
Resource[] resources = resourcePatternResolver.getResources(filePatter);
for (Resource resource : resources)
{
if (resource.isReadable())
{
List matches =
getMatches(resource.getInputStream(), pattern);
String fileName = resource.getURI().getPath();
if (errorWhenFound)
{
if (!matches.isEmpty())
addError(fileName + ": " + matches);
}
else
{
if (matches.isEmpty())
addError(fileName);
}
}
}
}
catch (IOException e)
{
addError(e.getMessage());
}
}
assertNoErrors(message);

Not sure... but could you try something like:

DownloadLink downloadLink = new DownloadLink("link_id", new
AbstractReadOnlyModel(){
public File getObject() {

},"myfile.xxx");
downloadLink.setOutputMarkupId(true);

and make linkModel a member variable? This way file will be "refreshed".

Re: DownloadLink problem

[Ernesto Reinaldo Barreiro]

Not sure... but could you try something like:

DownloadLink downloadLink = new DownloadLink("link_id", new
AbstractReadOnlyModel(){
public File getObject() {
return this.linkModel;
};
},"myfile.xxx");
downloadLink.setOutputMarkupId(true);

and make linkModel a member variable? This way file will be "refreshed".

Best,

Re: Ajax File Upload (Safari and Chrome)?

[bgooren]

Possibly this is related to  http://issues.apache.org/jira/browse/WICKET-2657
WICKET-2657 ?
That bug only mentions Chrome though, so it is unclear if it also occurs on
Safari.

Did you check if AjaxButton.onSubmit() gets called to isolate the problem
area (server vs client)?

Hi, Ernesto!

This is most likely the way I'll do the thing. I have a quartz scheduler and

DownloadLink problem

Hi, guys!

I experience some DownloadLink problem - I have these fields:

File linkModel;
DownloadLink theLink = new DownloadLink("link_id", new Model(linkModel));
theLink.setOutputMarkupId(true);

After another button click I have the linkModel field pointing to real file on 
the file system. And then I say:

target.addComponent(theLink);

the link name is still invisible, and when I click on the small clickable area, 
Wicket comes up with:

[MarkupContainer [Component id = exported_file_link]] threw an exception

Re: How to encrypt/obfuscate resource reference?

Err, I guess I don't quite understand what you're proposing... My
understanding is that I need to know all class names that are used by
application as part of ResourceReference (and possibly something else too).
How would I scan for that?

Create a unit test case that scans your application for resources and
checks if the class is set. If not, fail. If set, check if it is
unique, if not fail.

Thank You very much Thomas. 

I move code from getObject() method in IModel to load() method in
LoadableDetachableModel and everything works! - no more useless requests to
db :)

LoadableDetachableModel model2 = new LoadableDetachableModel() {

@Override
protected Object load() {
   ...
   // getting list from DB
   List  list = ;
   return list;
}
};

A flag has been introduced that when set will throw an error when an
fqn would be used. It will be in 1.4.7, which is currently in the
voting phase, so it will be available within a week.

But this would mean you'd have to alias all the classes anyway.

Re: How to encrypt/obfuscate resource reference?

[bgooren]

Ok, scratch that comment too...

I see Antoine dug up an old thread of yours where you already found out
about the possibility to override WebRequestCodingStrategy.

I also see that Antoine created WICKET-2731 and that it has been closed as
resolved/fixed, so there should be some hooks available in wicket 1.4.7
(which is to be release shortly according to the dev mailing list).

Re: How to encrypt/obfuscate resource reference?

[bgooren]

Sorry, I overlooked that part of your original post.

I've been toying with the same idea, since class aliases are bound to cause
problems as projects grow bigger. As long as the aliases are user-generated,
they might not be unique.

So I had a quick look at the source code of WebRequestCodingStrategy, and I
think it should be possible to create a solution for your problem quite
easily:

1) subclass WebRequestCodingStrategy, and use it by overriding
newRequestCycleProcessor() in your application, and return a subclasses
WebRequestCycleProcessor which returns your custom WebRequestCodingStrategy
in the call to newRequestCodingStrategy(). Quickest solution is to create an
anonymous inner class for the custom WebRequestCycleProcessor
2) override the 
http://wicket.apache.org/docs/1.4/org/apache/wicket/protocol/http/request/WebRequestCodingStrategy.html#encode(org.apache.wicket.RequestCycle,
org.apache.wicket.request.target.resource.ISharedResourceRequestTarget)
encode  method which deals with shared resources, and implement "encryption"
(or simply an obfuscated, stable alias for classes)
3) override 
http://wicket.apache.org/docs/1.4/org/apache/wicket/protocol/http/request/WebRequestCodingStrategy.html#addResourceParameters(org.apache.wicket.Request,
org.apache.wicket.request.RequestParameters) addResourceParameters()  and
implement "decryption"

That's exactly what is supposed to happen, as getModelObject() is just a 
shorthand for getModel().getObject(). And in your getObject(), you do 
the database request.


If you need to avoid those database reloads, look into 
LoadableDetachableModels.

Re: Re: FormTester and Select component?

[Leo . Erlandsson]

You could easily extend WicketTester and FormTester to support selecting 
in org.apache.wicket.extensions.markup.html.form.select.Select.

Take a look at the

public void select(String formComponentId, int index)

method in FormTester and

public FormTester newFormTester(String path, boolean fillBlankString)

in BaseWicketTester on how to do it.

[Ernesto Reinaldo Barreiro]

just answered what he was asking;-). Another thing is if this is the best
solution for the use case. Maybe another possibility is to have a
background job that does clean unused files from time to time.

Re: FormTester and Select component?

[Jan Eriksson]

Thank you for the reply. Unfortunately this is not easier for me since
we already have this function implemented using the Select component.
If there is no way of getting FormTester to work with that component
i'll have a look at your code - i really want to have this test
automated without having to use a heavier test framework.

Re: RE: How can i know when a users redirects to other page

[Sergey Olefir]

I'm not sure if session invalidation will be carried out if server
stops/crashes. Although I think the session invalidation mechanism is still
the most reliable of all that was proposed (my personal first reaction was
"you can't do it reliably" -- although after reading the thread I have to
agree that e.g. session invalidation might work).

Anyway, if going session invalidation route, it might be necessary to clean
up the directory at the server startup to make sure all stray files are
cleaned up.

Re: How to encrypt/obfuscate resource reference?

[Sergey Olefir]

As I briefly mentioned before, class aliases are, IMO, a terribly unreliable
thing to maintain. Every time someone comes up with new component that uses
resource reference they must not forget to go and register the alias for it. 

I'm predicting a 100% probability that soon enough someone will forget it
and it'll go into production -- thus defeating the entire purpose behind the
encryption/obfuscation :)

And to comment on what Antoine is saying -- I'm not entirely sure what did
you mean, but if I tried to implement encryption at
CryptedUrlWebRequestCodingStrategy, I will have to ensure that encrypted URL
will have format that will be fully parseable after browser appends relative
CSS URL to it. This is manageable by, say, encrypting only the section of
the path containing the class name. But then I'm completely unsure as to how
properly decode it / fake request for Wicket. The existing code only 'fakes'
parameters string -- but there are API methods that deal with request path
as well, and if those are not correct, I'm not sure what issues that may
cause.

Bottom line -- it must be possible to do encryption at
CryptedUrlWebRequestCodingStrategy, but it will take some serious digging to
make sure all parts fit correctly. It would be far easier to e.g.
automatically add alias in SharedResources method that deals with assigning
the name to shared resource -- the only thing it'll require is to modify
Application class so that e.g. getSharedResources() is not final.

But I'm still hoping for some 'easy' solution that doesn't entail modifying
Wicket source code to avoid headaches when upgrading.

FormTester and Select component?

[Jan Eriksson]

We're using a Select component
(org.apache.wicket.extensions.markup.html.form.select.Select) to
display two groups of SelectionOptions in a Form. I guess that is the
correct component to use when you want to group options and render
them in optgroup's?

Anyway, we would like to test the form using FormTester but when i try
to select a value we get the following exception:

org.apache.wicket.WicketRuntimeException: Selecting on the
component:'0:paymentFormForm:paymentType' is not supported.
at org.apache.wicket.util.tester.FormTester.fail(FormTester.java:824)
at 
org.apache.wicket.util.tester.FormTester.access$100(FormTester.java:59)
at 
org.apache.wicket.util.tester.FormTester$ChoiceSelectorFactory.create(FormTester.java:308)
..
..

and the test code:

FormTester ft = tester.newFormTester("paymentForm", true);
ft.select("paymentType", 0); // paymentType is the id of the Select component


Any help would be appreciated!

Bug in DateTimeField related to Daylight Savings Time

[Tauren Mills]

In case anyone else is having troubles using the DateTimeField (date picker
included in wicket-datetime) with dates on the day daylight savings time
begins (3/14/2010), I've created a Jira issue with a quickstart
demonstrating the problem:
https://issues.apache.org/jira/browse/WICKET-2763

Essentially, I'm having troubles with an exception being thrown when using a
DateTimeField. This is only happening on 3/14/2010 when the Hour field
contains a 2, regardless if it is AM or PM. I believe this is related to
daylight savings time starting at 2AM on 3/14/2010. Times between 2:00AM and
2:59AM don't exist, since at the moment 2:00AM happens, it is actually
3:00AM. This wouldn't be that big of a deal in my app for the 2AM times, but
it even causes an exception when the the date is set to 2PM, because the
logic is setting the JodaTime hour to 2 (not 14) before checking the AM/PM
setting.

Here is the exception:

Caused by: org.joda.time.
IllegalFieldValueException: Value 2 for hourOfDay is not supported: Illegal
instant due to time zone offset transition: 2010-03-14T02:00:00.000
(America/Los_Angeles)

At the moment, I'm using 24 hour mode instead of 12 hour mode so that the
only time there is an error is at 2AM and not also 2PM.

DateTimeField start = new DateTimeField("start", new
PropertyModel(itemModel,"start")) {
@Override
protected boolean use12HourFormat() {
return false;
}
};
add(start);
