A question for Igor

[Matthew Young]

I am looking at the wicket.markup.html.tabs.TabbedPanel
(wicket-extensions)http://wicketstuff.org/wicket13/compref/?wicket:bookmarkablePage=%3Aorg.apache.wicket.examples.compref.TabbedPanelPageexample
on
http://wicketstuff.org/wicket13/compref/, I couldn't figure out how you
switch the css.  Is that done in WicketExamplePage?  Unfortunately,
WicketExamplePage.java is not part of the source.

Re: A question for Igor

[Igor Vaynberg]

the code is on TabbedPanelPage, the links simply switch the css class
that is on the div tag used to attach to tabbed panel.

Re: Request for hints: Long duration requests; ajax 'status' line

[lars vonk]

Hi,

The code in the blog contains some visibility issues. So I wouldn't use that
code in your application without making it Thread safe.

Since the write and read of the uploading and uploadComplete flag happen in
different Threads access to those variables must be either protected by a
lock or you can declare those attributes volatile. Otherwise the JMM gives
no garantuee what so ever about changes made to those variables in one
Thread can be seen in another Thread.

So before you use the code either declare the uploading and uploadComplete
flag as volatile or make the isXXX and setXXX methods synchronized.

Cheers, Lars

new TextField(number, ..., Integer.class);

Integer-ness is checked at conversion level before validation.

  what we could do now is the following:

 Hi,

 I am using the autocomplete feature of Wicket, and I would
  like
 the
user
 to see the entire list of available values when the input
  field is
empty.
 Then, as he starts typing values in the input field, the
 list
  of
values will
 narrow down.

 However I see that when the input field is empty, the popup
  for
 autocomplete is not displayed (for example when I press
 down
 arrow).
I
 searched in the wicket code and I saw that in file
wicket-autocomplete.js,
 in function doUpdateChoices there are two checks for the
 situation
when
 the input field is empty. These checks don't allow for the
  popup
 to
be
 visible.

 So, my questions would be: does anyone know why this was
 done
  so,
and can
 I somehow disable this behavior? I would find it really
  useful to
 be
able to
 display a list of values even when the input field is
 empty.

 Thank you,

Re: Show feedbackpanel on modalwindow

[Maurice Marrink]

Add a feedbackpanel to the modal window.
If needed you can also use a IFeedbackMessageFilter on the
feedbackpanels to decide which panel shows which message.
In the ajaxsubmit you should also add the feedbackpanel on the
modalwindow to the ajaxtarget

VOTE: Generics of IDataProvider

[Jan Kriesten]

Hi,

I have a usecase where the current proposed generic Interface for IDataProvider 
with upcoming v1.4 of Wicket would break the implementation concept working with 
Wicket 1.3. The usecase needs different types for iterator + model. Example and 
explanation are found below the vote:


VOTE:

[ ] IDataProviderI,T
[ ] IteratorIModelT , drop model
[ ] Leave as is.


Example:
new IDataProviderInteger, Topics {
  public IteratorInteger iterator( int first, int count ) { 
getForum().getTopics( first, count ); }


  public int size() { getForum().getTopicsCount(); }

  public IModelTopics model( Integer id ) { return new TopicsDetachableModel( 
id ); }

 }

The current proposed IDataProviderT would enforce model + iterator to be of 
the same type, resulting in the above not working without hassle. I.e. either to 
work without type safetey (always use Object to comply), or wrapping/querying 
the type within iterator + model (which could cause time consuming lookups when 
remote services are involved).


To get around this, there are 2 solutions:

- drop the 'model' method and have iterator return an IteratorIModelT

That would fit this usecase since the Model could just be wrapped within 
iterator and no extra lookups would be necessary. Implementation code of 
iterator might get a bit uglier, though.


- add a second type as shown with example above

Would lead to redundant type definitions for many usecases where iterator + 
model actually return the same type.



I'd really like to see support for generics with these cases as well.

Best regards, --- Jan.

Re: default spring transaction on request cycle

[lars vonk]

I would advice you to group the transactional beans in one Service, define
that service in Spring and make it transactional. By using the proper
Transaction Propagation levels the wrapped beans can use existing
transactions if there is one.

See
http://static.springframework.org/spring/docs/2.5.x/reference/transaction.htmlfor
more info on Spring and Transactions.

I dont care much between those 2.
But i definitely  dont like option 1, because your example gives me exact
the feeling why i dont want that
It gives the wrong idea to peoples mind. If they would do what you do,
Integer list of pks, and then in the model you get the Topics objects,
this would for most OR mapping tools be a real performance issue, and we get
the blame for that for being slow.

Hi!

I want to save images to a specified uploadfolder, but I don't want to
define the Folder object with an absolute path. Is there a possiblity to

If memory serves, then you can get access to the servlet request, and pull
out the context path from your page via:

getWebRequestCycle().getWebRequest().getHttpServletRequest()

Re: StatelessForm + UrlCompressingWebRequestProcessor

[Martin Grigorov]

It have to be something with my application settings ...
I just tried with simple quickstart and there is no exception.
Though the produced URL is not compressed again:

form id=loginForm1 action=../login/?wicket:interface=%3A0%
3AloginForm%3A%3AIFormSubmitListener%3A%3A method=post
wicket:id=loginForm

I'll try to debug it.

  Yeah, that's how it works. There's a fileupload.js that leverages
  jQuery. When the user presses the upload button it does a binary upload
  to a page of your choosing - that's where I had to change the existing
  PHP-integrated lib that I used as a template. I used a Page that was
  accessible via a mapped URI to parse out the stream and store it to the
  backend. Then I bounced back a JSON msg, which can contain various
  status and error notifications. Those can be popped up as JS alerts,
  which is kind of cool. I even managed to bounce back the image id and
  the local path, so that I could do some frontend magic. Works just fine
  - one of the other problems was to make it work with Wicket since the
  component ids had to match. This was done by injecting the proper ids
  into the JS lib when loading the enclosing page.
 
  A bit of a hack, I know - but it's working, which is all I care about.

Clicking a tree leaf and confirmation

[Federico Fanton]

Hi all!
First of all, I'd like to celebrate the achieved complete elimination of JSF 
from our project here, thanks to Wicket :)

Next, I'm facing a little problem..
I have a LinkTree and I'd like to make it ask for confirmation (via a JS alert) 
whenever the user clicks on a leaf.. If the user confirms, a component of the 
page should be AJAX-refreshed, otherwise nothing happens.
The AJAX part works right now, I need to add the confirmation bit.. I thought 
I'd override BaseTree.newLink and decorate the AJAX call, but from that method 
I can't tell if the link will be related to a leaf or a folder.. Am I going the 
wrong way? Maybe newLink(id, callback) could be expanded to something like 
newLink(id, callback, model)?

Many thanks for your attention!

Re: Problem with how to make variation

[StephenP]

It seems to be working ok for us although we're not in production yet. One of
our aims is to avoid code duplication across many sites and make deployment
easy (i.e. not having to deploy and cluster individual sites  in their own
war files)

Yes, we do edit the hosts file for testing, but you could investigate if you
could do things with apache virtual hosting or maybe a firefox plugin like
Tamper Data to edit the host header, if thats not an option.

I'll let you decide if its a good idea.

  Hi,

  I have a usecase where the current proposed generic Interface for
 IDataProvider with upcoming v1.4 of Wicket would break the implementation
 concept working with Wicket 1.3. The usecase needs different types for
 iterator + model. Example and explanation are found below the vote:

  VOTE:

[ ] IDataProviderI,T
[X] IteratorIModelT , drop model
[X] Leave as is.

I like the idea that the standard usecase is somewhat enforced by
the interface.  I agree that the integer - object mapping usecase is
not common and could lead to performance problems.  However, I'm
somewhat torn between the last two options.  Having that model method
there was somewhat confusing in the first place when I was learning
about it, but that could just be because generics weren't there to
begin with to make it a bit more clear.  If we go with option #2, then
we're basically putting the modelizing logic onto the user.  But, if
we stick with it the way that it is, we're taking care of modelizing
each item in the iterator for them (by using their method of course).
If 99% of the people are going to have to write a method (the
iteratorT - iteratorIModelT transforming method), then why not
just do that stuff for them and allow them a bit to customize it (like
the model method)?

  In my test I have:

  When I run this through a jetty server I get 1 call to the load method of
  my TestFeature model.

  When I run the test I get 2 calls to the load method.  The 2nd seems to be
  triggered from the assertLabel call.  If I have many assertLabel calls -
  then its still called only twice.  Ie, more assertLabels do no call load
  again.

  Any ideas why?


The first call to load happens during rendering.  When rendering is
done, your model is detached.  Then, the call to assertLabel() forces
the model to be loaded again.  Then, subsequent calls to assertLabel()
would not require a load because the model hasn't been detached.

Can you move the verify stuff up above the assertLabel?  Would that
help?  The verification you're looking for is to verify that stuff is
called correctly during rendering.  The assertions don't need to go on
within the context of the replay of the mocks.

Re: Problem with how to make variation

[Mathias P.W Nilsson]

Another question for this.. 

The site1.com text will be different from Site2.com text even if the
resource key is the same the
text will not be the same. Can you set a resource based on locale and style?

Re: default spring transaction on request cycle

[Stefan Selariu]

Thanks for your answer, but sadly this is not possible.
I cannot group the beans in one service because the beans are invoked
from different wicket components.
I need the request cycle to be transactional because on the submit event
one component calls the required transactional service and at render
time the page components sometimes need to invoke other transactional
beans to complete the rendering.

If I quit using spring's transactions support I could use onBeginRequest
and onEndRequest to start and close the transaction. This approach is
very limited (no nested transactions, very complicated transaction
exceptions handling, the spring beans need to be aware of the
transactions) and I don't like it :)

Has anyone an idea why RequestCycle is a class and not an interface?
This is a problem in my case :(

Thanks again.
Stefan

Re: Gzipping of pages (HTML output, not only resources)

At our wug CPH yesterday we talked about something similar (ajax), I

which does that.

Please, where in wicket can I add such a functionality or what/where should

Modal Window not opening the second time

[Marieke Vandamme]

Hello, 

i'm having problems with the modal window. It shows up fine when I click my
link the first time, but after closing the window with the 'X', it won't
open again.
I don't know if I'm using it wrong or if it's a bug. 
Any help is welcome ! thanks. Marieke.

My code :
public class TestModalWindow extends WebPage {

public TestModalWindow() {
final ModalWindow modal = new ModalWindow(dataChooser);
add(modal);
final MyChooser myChooser = new MyChooser(modal);
modal.setPageCreator(new ModalWindow.PageCreator() {

public Page createPage() {
return myChooser;
}
});

 add(new AjaxLink(lnkOpen) {

public void onClick(AjaxRequestTarget target) {
myChooser.reload(target);
}
});
}

public class MyChooser extends WebPage {

private ModalWindow window;

public MyChooser(ModalWindow w) {
this.window = w;
}

public void reload(AjaxRequestTarget target) {
this.window.show(target);
}
}
}

Re: default spring transaction on request cycle

[lars vonk]

I wouldn't advice you to do it in the requestcycle for the reasons you
already describe yourself:

- Too cumbersome
- All request are then in a Transaction (might no be a problem though).
- How to detect that a rollback is needed.

You could still use Spring transaction though: This could be a possible
implementation, but I don't know if this is rock solid especially the
rollback I am not sure about. This approach  will enable nested transaction
IHMO since it still uses the spring configured transactions.

class TransactionalRequestCycle extends WebRequestCycle {

  @SpringBean private TransactionManager txManager

  private TransactionStatus status;

  public TransactionRequestCycle() {
// this will inject the txManager from the spring context.
InjectorHolder.getInjector().inject(this);
DefaultTransactionDefinition def = new DefaultTransactionDefinition();
def.setPropagationBehavior(...);
  }

  protected void onBeginRequest() {
status = txManager.getTransaction(def);
  }

  protected void onEndRequest() {
txManager.commit(status);
  }
  protected void onRuntimeException() {
if(status != null)
  txManager.rollback(status);
  }
}

Re: Clicking a tree leaf and confirmation

[Thomas Kappler]

Hi Federico,

you gain a lot of flexibility when overriding newNodeComponent()
instead.  There, you return a custom Panel where you can do what you
want, i.e., add the link with all desired functionality.  And you can
of course give your Panel any constructor you like.

An example from our project:

protected Component newNodeComponent(String id, IModel model) {
return new SenseLinkPanel(id, SensesTabPanel.this,
(DefaultMutableTreeNode) 
model.getObject())
.setOutputMarkupId(true);
}

SenseLinkPanel is basically an AjaxLink with the right onClick()
functionality.  You see that via the constructor it gets the TreeNode
it represents, and the Panel the tree is in to update it via AJAX.

Cheers,
Thomas

 Hi all!
  First of all, I'd like to celebrate the achieved complete elimination of JSF 
 from our project here, thanks to Wicket :)

  Next, I'm facing a little problem..
  I have a LinkTree and I'd like to make it ask for confirmation (via a JS 
 alert) whenever the user clicks on a leaf.. If the user confirms, a component 
 of the page should be AJAX-refreshed, otherwise nothing happens.
  The AJAX part works right now, I need to add the confirmation bit.. I 
 thought I'd override BaseTree.newLink and decorate the AJAX call, but from 
 that method I can't tell if the link will be related to a leaf or a folder.. 
 Am I going the wrong way? Maybe newLink(id, callback) could be expanded to 
 something like newLink(id, callback, model)?

  Many thanks for your attention!

Re: Wicket tester calling load twice in loadableDetachableModel

Re: default spring transaction on request cycle

[lars vonk]

Well it technically shouldn't matter if you use the wicket-spring module I
guess.
It think it matters that you use the same TransactionManager and the correct
Propagation behavior (REQUIRED iirc). Did you use the same
transactionmanager in your previous attempt and what was the propagation
setting you used?

For wicket-spring see http://cwiki.apache.org/WICKET/spring.html, I would
suggest you use the annotation based approach.

Building javadoc for Wicket 1.4 from svn download

[Stefan Lindner]

The current Wicket 1.4 trunk does not create javadocs anymore (as
described on this list and on the build webpage). How can I create the
javadoc files with maven? I don't know maven mechanisms for this task.

When I build the project with maven javadoc:javadoc, the javadocs are
generated in the target directorys but not packed to jar files. How can
I let maven create the javadoc jar files?

Re: default spring transaction on request cycle

 Is it not the default propagation setting?


Yes you are correct.

In what way to use the same TransactionManager? The same
 TransactionManager spring bean? Or the same TransactionManager spring bean
 instance?


I meant instance.

Again I am not sure if this is enough, Mixing manual and spring managed
transaction goes a bit above my transaction management experience.

 I need the request cycle to be transactional because on the submit

 If I quit using spring's transactions support I could use

Re: am I doing right? entities no Serializables.

[Martijn Dashorst]

for a new entity you can always return a new entity. There is no need
to keep the filled in data between requests :-) as the fields have the
data already... When you return a new object Wicket's form update
mechanism will repopulate the object's fields.

Re: DropDownChoice getting value into the model

[Russell Webb]

I am experiencing something similar. My LoadableDetachableModel is wrapped
with a CompoundPropertyModel.

Submitting a TexTField acquires the AttachedCompoundPropertyModel whose
setObject() acquires the target object and persists changes. 
   
CompoundPropertyModel$AttachedCompoundPropertyModel(AbstractPropertyModel).setObject(Object)
line: 146   
TextField(Component).setModelObject(Object) line: 2888  
TextField(FormComponent).updateModel() line: 1060   
Form$19.validate(FormComponent) line: 1754  

Submitting the dropdown acquires the read only setObject()
VxsNewUserWizard$3(AbstractReadOnlyModel).setObject(Object) line: 52
BoundCompoundPropertyModel(CompoundPropertyModel).setObject(Object)
line: 72
DropDownChoice(Component).setModelObject(Object) line: 2888 
DropDownChoice(FormComponent).updateModel() line: 1060  
Form$19.validate(FormComponent) line: 1754  

It seems the model is linked to the two components differently and that this
causes different behaviour when using a CompoundPropertyModel (and perhaps
others) like allowing the ReadOnlyModel.setObject to be bypassed.

  two problems

  1) loadable detachable models do not support the setobject() call,

  model.

  2) yes, selectoption object will be put into your model, dropdown

Hi,

Beware of using getRealPath if your app is deployed on a Tomcat server where
it's set _not_ to unpack the wars (for instance 99% of the plesk domain
hostings).

It will always return null.

My 2 cents.

Re: default spring transaction on request cycle

[Igor Vaynberg]

you need to surround your code with something like ths:


PlatformTransactionManager ptm = (PlatformTransactionManager)ctx
   .getBean(transactionManager);

TransactionStatus txn = ptm.getTransaction(new DefaultTransactionDefinition());

...

ptm.commit/rollback(txn)

whether you do this in onclick() or on request cycle is up to you. but
like others have mentioned, you should probably do this lazily so that
not every request starts a transaction unless it needs it.

it is too bad spring doesnt provide a Filter to do this, a
single-transaction-per-request is a pretty common pattern.

The problem with this approach is what do you do if the transaction
cannot commit (i.e. constraint violation) and you've already written
some data back to the response stream (you can't undo that)?  That's
why it's better to bundle up all that you want to do into a service
method and call that under one transactional umbrella.  Once that
completes, then you can go on and render the response.

Wicket 1.4 and Wicketstuff/Dojo/DragAndDrop

[Stefan Lindner]

Is there a Wicketstuff/dojo version that works together with Wicket 1.4?
Is Wicketstuff/Dojo still alive? The latest news on the webpage state
that Wicketstuff/Dojo is still based upon wicket 1.3 beta.

Re: Can I create a form markup on the fly?

[Maurice Marrink]

No, you need to have matching markup and java code.

Perhaps you could set the form to invisible and
setOutputMarkupPlaceholder(true), that way an invisible tag (not form)
is used instead. However before you could submit the form you would
have to make it visible again on the server side (via ajax or a
regular request) the placeholder tag will then be replaced by the form
and you can immediately trigger some javascript to submit it if so
desired.

Re: Anyway to fix this generic warning?

ArthIT: How to suppress the warning is not why I asked the question.  I want
to be sure generify Wicket is correct so user code can be clean and warning
free.

in Eclipse go to Window - Preferences
Type Generic in the search box. Now you should see the
Java-compiler-Errors/Warnings Node.
Open it, and change settings under Generic types to whatever you want
(Ignore f.e.)

I don't do this because that covers up all the warnings of that kind. I
prefer to see the warnings and deal with them.  If the warning cannot be
fixed, I use @SupressWarning on the spot.

unit test of AjaxLazyLoadPanel and ModalWindow

[qk]

Hi there,

I am having problems testing AjaxLazyLoadPanel and ModalWindow using the
WicketTester. Here are my questions:

1. after the page was rendered using WicketTester.startPage(), the real
content (the one that returned by getLazyLoadComponent()) was not loaded by
default. I always got an empty panel. Is there a way that I can have the
real content rendered?

2. how can I bring up the ModalWindow using WicketTester so that I can make
sure that components on the modalWindow work as expected?

Thanks in advance for your help.

Cheers,
Ivan

Re: Best way to use borders tranparently

Re: default spring transaction on request cycle

[Stefan Selariu]

Indeed, my use cases don't allow to group the bean calls in another

Surrounding the bean calls with the transaction manager transaction  
solved my problem.

Now I'm even using wicket-spring since it have some nice features :)

Thanks guys.

Pageless component at AjaxRequestTarget detach

[Thomas Kappler]

Hi,

we have a BaseTree where we implemented reordering of tree nodes via
drag and drop, using wicketstuff-scriptaculous.  Everything seems to
work, i.e., you can work with the page as intended.  In the logs we
see an error on each drop event, however:

org.apache.wicket.RequestCycle detach
SEVERE: there was an error cleaning up target
[EMAIL PROTECTED] markupIdToComponent
[{containerb9=[MarkupContainer [Component id = container, page = No
Page, path = 21:nodeComponent:container.SenseLinkPanel$1]], SNIP
}], prependJavascript [[Droppables.remove($(containerb9));]],
appendJavascript [[new Effect.Highlight('containerb9',
{}
);
]].
java.lang.IllegalStateException: No Page found for component
[MarkupContainer [Component id = container, page = No Page, path =
21:nodeComponent:container.SenseLinkPanel$1]]
at org.apache.wicket.Component.getPage(Component.java:1658)
at 
org.apache.wicket.ajax.AjaxRequestTarget.detach(AjaxRequestTarget.java:437)
[...]

I verified in the debugger that this happens not during our code, but
in the ajax update after everything is done.  The component
container is the (only) top-level component of the panel
representing a tree node.  So, somehow during the node reordering, the
node panel seems to lose its page.

On the UI side, the nodes are DefaultMutableTreeNodes, and the
reordering is basically one line:
dropNode.add(dragNode);

I suspect it might be a bug in there, but I'm not sure where to start.
 Also, as I said, it seems to do no harm.

Using AJAX to change style of component

[Ryan O'Hara]

I'm fairly new to Wicket and was wondering if there is a way to use  
AJAX to change the style of a WebMarkupContainer?  Below is a snippet  
of my code:


IModel sourceModel = new Model() {
public Object getObject() {
return sourceOptions;
}
};
final DropDownChoice source = new DropDownChoice(source,  
new PropertyModel(this, sourceSelection), sourceModel);

source.add(new AjaxFormComponentUpdatingBehavior(onchange) {
protected void onUpdate(AjaxRequestTarget target) {
variationMetricRow.add(new AttributeModifier 
(style, true, new Model(sourceSelection.equals(CHOP_Normals) ?  
display:block : display:none)));

variationMetricRow.setOutputMarkupId(true);
target.addComponent(variationMetricRow);
}
});

In this example,  I would like to change the display to show/hide a  
particular component.  Any help would be appreciated.


Thanks,
Ryan

Re: intro and explanation about DataTable and DetachableModel

[Doug Donohoe]

This may help.  I am moving my DD Poker site to wicket and implemented an
IDataProvider around my database service as follows:

private class HistoryData implements IDataProvider
{
private static final long serialVersionUID = 42L;

private PokerUser user;
private int count;

private HistoryData(PokerUser user)
{
this.user = user;
count =
histService.getAllTournamentHistoriesForProfileCount(user.getId());
}

@SuppressWarnings({RawUseOfParameterizedType})
public Iterator iterator(int first, int pagesize)
{
return
histService.getAllTournamentHistoriesForProfile(user.getId(), count, first,
pagesize).iterator();
}

public int size()
{
return count;
}

public boolean isEmpty()
{
return count == 0;
}

public IModel model(Object object)
{
return new CompoundPropertyModel(new EntityModel(object));
}

public void detach()
{
}
}

Where EntityModel is:

public class EntityModel extends CompoundPropertyModel
{
private static final long serialVersionUID = 42L;

/**
 * Constructor
 *
 * @param object The model object, which may or may not implement IModel
 */
public EntityModel(Object object)
{
super(new NonLoadableDetachableModel(object));
}
}

and NonLoadableDetachableModel is

public class NonLoadableDetachableModel extends LoadableDetachableModel
{
private static final long serialVersionUID = 42L;

public NonLoadableDetachableModel(Object model)
{
super(model);
}

@Override
protected Object load()
{
throw new UnsupportedOperationException(load should never be
called);
}
}

I created this last class because my pages are read-only and the result set
is always fetched through the service.  I didn't want to have my (JPA based)
entities being serialized.

The HistoryData class worked great with the base DataView class in Wicket.

Note that I drew a lot of inspiration from:

http://wicketstuff.org/wicket13/repeater/

and digging around in the source.

I don't know if this will help you or not - hopefully so!

 Hi,
 Can anyone give me an explanation about paging with DetachableModel?
 
 My problem:
 We have records in the DB that can be a-lot.
 We also filter them sometimes.
 
 someone in the company created a non-standard paging.
 He doesn't use the Wicket's paging.
 
 The iterator method of the DataProvider he created returns only the number
 of elements that should be displayed in the current page.
 Eg. suppose we decided we show 20 records per page.
 The DataProvider keeps track on which page we're at.
 Then he calculates the indexes of records.
 It's done in getVisibleTickets() method.
 int fromIndex = (currentPage - 1) * (ticketsPerPage);
 int toIndex = ticketsPerPage;
 
 And then he asks the DB for the records in this range (with the filter).
 This is the size() method:
 public int size() {
 if ((visibleTickets == null) || (update)) {
 getVisibleTickets();
 }
 return visibleTickets.size();
 }
 
 OK, I hope i was clear enough.
 I know that it might be done using Wicket's library.
 Can anyone explain?

PageParameters request-for-enhancement

[Doug Donohoe]

Hi Wicket team:

I'd like to be able to call getInt(name, default) and not have to worry
about catching exceptions.  If the number can't be parsed, just return the
default.

I have a utility method which I use:

public static int getInt(PageParameters params, String name, int def)
{
try
{
return params.getInt(name, def);
}
catch (StringValueConversionException ignored)
{
return def;
}
}

Basically for my bookmarkable pages, I don't care if a user mucks with the
URL - this would let me default to something reasonable.

It would be nice if there were a comparable method on PageParameters ...
like getIntSafe(name, def) or some something similar (and for other
number-based getters).

In addition, it would be nice to have a getInteger() object method that
returns null if not defined or an Integer object.  The way it is now, I have
to pick a default value that I assume won't ever be valid (usually -1). 
There are valid use cases where null is an expected value.

It creates a new frame via JS, yes. I want to send this to you, but it has to 
be packaged properly and commented so you know what is happening. My project is 
keeping me up late, is it okay if I do this during the weekend?

I really don't think it can be done w/o an iframe.

@Fabien - here's the (simple) code:

 Hello Michael,

 Could you share this fileupload.js? I'd bet it creates some iframe tag via
 DOM manipulation ;-)

  Yeah, that's how it works. There's a fileupload.js that leverages
  jQuery. When the user presses the upload button it does a binary upload
  to a page of your choosing - that's where I had to change the existing
  PHP-integrated lib that I used as a template. I used a Page that was
  accessible via a mapped URI to parse out the stream and store it to the
  backend. Then I bounced back a JSON msg, which can contain various
  status and error notifications. Those can be popped up as JS alerts,
  which is kind of cool. I even managed to bounce back the image id and
  the local path, so that I could do some frontend magic. Works just fine
  - one of the other problems was to make it work with Wicket since the
  component ids had to match. This was done by injecting the proper ids
  into the JS lib when loading the enclosing page.
 
  A bit of a hack, I know - but it's working, which is all I care about.

  really?
  are you using the XMLHttpRequest  request to do a binary upload with a

   My researches show FileUploadField does not support ajax behavior
  
   So there is no wicket input, which permits to the user to browse his
   local
   disk?
  
   Thank you in advance.

Hi, I would like to add a behavior on my FileUploadField
   
But I can't get back the path of the file, or the file
   
this.logo = new FileUploadField(inputLogo);

  logo.add(new AjaxFormComponentUpdatingBehavior(onchange) {
  private static final long serialVersionUID = 1L;
protected void onUpdate(AjaxRequestTarget target) {

I have try everything :
   
FileUpload up = logo.getFileUpload(); - null
File file = (File)logo.getModelObject(); - null
logo.getModelObjectAsString() - null
   
So how can i get the file or just the path and the name file

RE: Integer only NumberValidator?

[Michael Mehrle]

Man, of course - I was so focused on NumberValidator that I completely
forgot about the Integer.class setting which I already have!

Q: what is the validator I need to refer to when defining my custom
error message in my properties file?

Integer-ness is checked at conversion level before validation.

Re: Administration in wicket

[Jeremy Thomerson]

I did it this way, although you may not want the extra path for other
pages

In WebApplication.init() :

mountBookmarkablePage(admin, AdminHomepage.class);
mount(admin/pages, PackageName.forClass(AdminHomepage.class));

Hope this helps,

Re: Administration in wicket

[Jeremy Thomerson]

This made me think of an easy extension to
PackageRequestTargetUrlCodingStrategy... what does everyone think?

Where we see that there is nothing left after the mount path, here: (line 88
in 1.3.3)
// There is nothing after the mount path!
return null;

Why don't we return getDefaultPageClass() which could be an optional
constructor parameter?

make sure you use UploadWebRequest in your application subclass, see
its javadoc for details.

Class casting exception while using PageParameters

[jianfei]

Hi, I'm new to the wicket framework, and I have a problem while using the
PageParameters.

I want to add a class instance as the value of one of the page parameters,
so I did this:

MyClass instance = new MyClass();
PageParameters param = new PageParameters();
param.put(classInstance, instance);

Then I want to get back the parameter as the class instance, so I use:

MyClass theInstance = (MyClass) param.get(classInstance);

This works fine if I put it right after the param.put(...) statement.
However, when I tried to pass the param to another page as a parameter for
the constructor, it throws a class casting exception. I also tried to do
new PageParameters(new HashMapString, MyClass()), but that didn't work
as well.

So can anyone help me solve this problem? Thanks a lot!

pageparameters represent url parameters, so they can only contain strings

External Error, Expiry , AccessDenied Pages

[mfs]

Guys,

I was wondering, if i were to redirect to external error, expiry and
access-denied page. Is there a better solution then to make individual
page-class for above and do a redirect to the corresponding pages in their
constructor? Since setAccessDeniedPage, setInternalErrorPage (in
ApplicationSettings) all take Class class as argument..

Thanks in advance
