what could have caused this: a page ID in listener URL getting a wrong page instance

2011-11-03 Thread Kent Tong

Hi,

My users are frequently getting internal errors after a few minutes
of inactivity. From the log I can see that mostly this is caused by:

org.apache.wicket.WicketRuntimeException: component foo not found
on page XYZ[id = 3], listener interface...

The weird thing is that there is no foo component on page XYZ, but
it is on page ABC. It means that while the browser believes that page
3 is an instance of ABC, actually it is an instance of XYZ.

What could have caused this? I know this is a long shot, but just to
see if there is any (remote) ideas. I can rule out session expiration
as it only took a few minutes to occur.

We're using Wicket 1.4.9.

Thanks in advance!

Strange issue in RequestCycle

2011-10-16 Thread Kent Tong
Hi,

In 1.5, the request cycle (indirectly) contains a stack of request handlers.
According to the Java docs, it seems the purpose is to allow a request
handler to execute another request handler in its respond() method by
calling the execute() method in the request cycle. However:

a) There seems to be no code in Wicket doing that and I don't see why
one would want to do that. What's the use case?

b) There is no execute() method in the RequestCycle class at all. So
there is actually no way for a request handler to call execute() on invoke
another. Does it mean that there is inconsistency here?

c) Even if there were a way to execute another request handle inline,
there is only one scheduledAfterCurrent in the request cycle. This would
cause problems of the inlined request handle schedule another handler,
right?

Re: Strange issue in RequestCycle

2011-10-16 Thread Kent Tong

Hi Igor,

Thanks for the reply!

 the usecase is simple, one requesthandler handing work off to another
 one. an easy example is a request handler that handles a callback
 (such as a link being clicked) scheduling the handler that renders the
 page after it handled the click.

Yes, it is very common for one request handler *scheduling* another
to be executed after its own execution. However, I am referring to
one request handling *executing* another during its own execution.

 all scheduled handlers go into a queue and are executed in order.
 usually there are only two handlers scheduled - event handler and page
 renderer.

The code shows that the scheduled handler is stored into the single
scheduledAfterCurrent field in RequestHandlerStack, while the
requestHandlers linked-list is not really used. The only location
a request handler is added to the linked-list is in the execute()
method, but it is immediately removed after its execution.

why generate hybrid URL for stateless page?

2011-09-13 Thread Kent Tong
Hi,

In 1.5 I found that even if a page is stateless, Wicket still generates
hybrid URLs (with PageInfo) for stateless links/forms. This is done in
AbstractBookmarkableMapper (see below). Any idea why? Thanks!


if (requestHandler instanceof BookmarkableListenerInterfaceRequestHandler)
{
// listener interface URL with page class information
BookmarkableListenerInterfaceRequestHandler handler =
(BookmarkableListenerInterfaceRequestHandler)requestHandler;
Class? extends IRequestablePage pageClass = handler.getPageClass();
if (!checkPageClass(pageClass))
{
return null;
}
Integer renderCount = null;
if (handler.getListenerInterface().isIncludeRenderCount())
{
renderCount = handler.getRenderCount();
}
PageInfo pageInfo = new PageInfo(handler.getPageId());
ComponentInfo componentInfo = new ComponentInfo(renderCount,
requestListenerInterfaceToString(handler.getListenerInterface()),
handler.getComponentPath(),
handler.getBehaviorIndex());
UrlInfo urlInfo = new UrlInfo(new PageComponentInfo(pageInfo,
componentInfo),
pageClass, handler.getPageParameters());

assuming that you the button to open the modal window has a Wicket ID of

Hi James,

 Why is spring-orm version 3.0.1.RELEASE and not 3.0.3.RELEASE?  Why
 not just uset a {spring.version} property in your POM so that it all
 stays in synch?

Thanks for your good advice. I've updated the tutorial.

 Why do you have page - service - dao?  Why not just talk directly to
 the DAO for the getAll() method.  This level of indirection just
 causes more code (and confusion) in your simple example.  Is this just
 a best practice that you've devised?  I've never really understood
 folks' aversion to talking to the DAOs from the view layer, especially
 when it means you have to have duplicate methods in your service layer
 to do so.  It just doesn't make sense to me.

I agree that if the service is simply delegating to the DAO without
adding anything, then it is probably be a good idea to merge them.
However, this sample application is meant to demonstrate how to do
it in a general case where the service does more than simple delegation.

Re: Confirmation dialog during file upload

2010-06-18 Thread Kent Tong
 I have a form which allows a user to upload a file. The form is
 patterned after upload Wicket example.

 If the file being uploaded will overwrite an existing file I need to
 prompt the user if they want to replace the existing file or not.
 What's the best way to implement this functionality?

There is nothing special about it. Just display a confirmation page. Only
if the user chooses to go ahead, will it save the file. Below is an example
doing that written in Scala (as my exercise in learning Scala):

class MyPage extends WebPage {
  val f = new Form[Unit](f) {
override def onSubmit = {
  val exists = true
  if (exists) {
setResponsePage(new ConfirmSavePage(upload.getFileUpload))
  } else {
Console.println(saving the file
+upload.getFileUpload.getClientFileName)
  }
}
  }
  add(f)
  val upload = new  FileUploadField(upload)
  f.add(upload)

}

class ConfirmSavePage(upload: FileUpload) extends WebPage {
  val f = new Form[Unit](f) {
override def onSubmit = {
  Console.println(saving the file +upload.getClientFileName)
}
  }
  add(f)
  val cancel = new Button(cancel) {
override def onSubmit = {
  Console.println(Aborting)
  setResponsePage(classOf[MyPage])
}
  }
  f.add(cancel)

Re: Confirmation dialog during file upload

 1. User clicks Upload button and form submission request is sent to the
 server
 2. The code on the server detect the file name collision and causes a
 ModalWindow to display

These can be done with an AjaxButton to send the upload request. Then
show the ModalWindow in onSubmit().

 3.1 If the user clicks Confirm button then upload form submission is
 resumed.

The Confirm button would be another AjaxButton then. Just save the
file in onSubmit(). Of course, make sure you copied the file content
in the first place for use here.

Re: How to test a link in wicket:links

2010-06-03 Thread Kent Tong

Hi Kent,

Thanks for the answer, but that looks like it requires Spring, I'm not using
Spring. I was hoping to use the test framework that is included in Wicket,
not go outside it. 


Well, it doesn't require you to use Spring in your code. However, it is
indeed assumed that you're using a IoC framework (eg, Spring or Guice).
Why? Only when you do, is it possible to really unit test a page,
otherwise your page will be invoking the real business logic and
database access in the tests.


I come across this doing a demo of Wicket and it kind of broke the whole
spiel about Look, you can do unittests of the GUI!! thing.


That's exactly the point. If your tests are touching the database, then
they aren't really unit tests anymore.

Didn't notice that. wicket:path would work. However, I really think my
solution is better because
you don't need to specify the full path (which may change easily). In most
case, one only needs
to specify wicket=//my-component-id.

Wicket page test 1.3 is now available

2010-03-26 Thread Kent Tong
Dear all,

Wicket page test 1.3 is now available. It is a library allowing you
to unit test your Wicket pages easily, supporting AJAX and
Javascript without changes to your pages.

New features implemented in this version:

* Provide a generic starter page to launch another page whose
constructor needs some arguments.
* Provide a page navigator to inspect the arguments passed to the
response page.
* Easier way to open a page.

Get it from maven as described in http://wicketpagetest.sourceforge.net/

Wicket page test allows you to unit test Wicket pages easily including

Major enhancements in 1.2 is that now you can wait for the completion
of Ajax easily, without writing any Javascript. For example, in a test

WicketSelenium ws = new WicketSelenium(selenium);
selenium.click(link=Calculate next); //this is an ajax link
ws.waitUntilAjaxDone();
assert selenium.getText(output).equals(Current: 1);

The javascript condition is usually testing for existence of some HTML

In my view, this is part of the test: it is part of the expected behavior

small library to unit test Wicket pages

2009-11-08 Thread Kent Tong

Dear all,

I've made a small library to unit test Wicket pages: It launches Jetty
to run your webapp in-process and launches the Selenium client. Then you
inject POJO mock objects into @SpringBean annotated fields and use the
Selenium client to drive your page.

Why I think it is useful?
* The key benefit is that you can control the right thing (the data your
pages get, from the services), and then observe the right thing (HTML
DOM elements, possible manipulated by Javascript/AJAX).

* Your real application is run. You don't need to modify it in anyway.

* It's very easy to implement as it relies on well established tools
(Selenium and Jetty). It means it can easily be kept updated with new
versions of Wicket.

* Potentially this approach can be applied to frameworks other than
Wicket.

You're welcome to test it. Visit
http://wicketpagetest.sourceforge.net/index.html for more info.

Leaving it as is just doesn't make sense as it doesn't support the use case

Using IDataProviderI, T is OK too. For those whose I == T, we can always
have a convenient base class:

abstract class ModelProviderT implements IDataProviderT, T {
  IModelT model(T object) {
return object;
  }
}

IteratorIModelT will make the interface simpler. For those who
need to wrap domain objects as models, we can provide a wrapper
iterator:

abstract class ModelWrapperIteratorT implements IteratorT {
  ModelWrapperIterator(IteratorT source) {
...
  }
  abstract IModelT map(T sourceElement);
}

You can always create your own TabPanelTester that may have a getTab(id) 
method. This class will encapsulate the internal knowledge.

Why not add the form validator to the wizard step? It has an add() method

You may try overriding the onRender() method in the Page class in
your own page class to retrieve the cached output.

However, I really don't think this is necessary as Wicket pages involves
no compilation of any kind like OGNL, the render time should be quite
consistent.

 As far as I can tell, there's still only 1 resource, which has the

Every time the page is rendered, it will generate a different variant of

 But I have a link on the page which allows you to change the locale. 
 This link is stateful, so it just calls the callback on the current page

No problem. If the link is a normal link (not ajax), you'll render the
page again and thus will have a new resource reference. If it's
ajax, you need to put the setLocale() call into a callback and
refresh the link.

 Incidently there is a Classes class that has some handy cached stuff for

 see org.apache.wicket.util.lang.Classes
 

You can certain make the PanelFactory a spring bean:

public class TestPage extends WebPage {
@SpringBean(name = panelFactory)
private PanelFactory panelFactory;

public TestPage() {
add(panelFactory.getPanel(testPanelOne));
}

}
bean id=config class=myapp.Config scope=singleton

valuemyapp.TestPanel/value
/property
/bean
bean id=panelFactory class=myapp.PanelFactory scope=singleton
property name=config ref=config/
/bean


The Wicket Classes class is not meant for performance. Normal classloaders
probable 
provide better caching support. It was introduced to fix concurrency

required for Checkbox

2008-01-07 Thread Kent Tong

Hi,

I observed that if required is set to true for a Checkbox, Wicket will
ensure that the Checkbox is checked. If it is cleared by the user, it
will be treated as an error. See 
https://issues.apache.org/jira/browse/WICKET-1221 and
https://issues.apache.org/jira/browse/WICKET-1260 for some
background.

For me, required means that a value must be provided. For a 
check box, if it is checked, it has a value of true. if it is unchecked, it 
has a value of false. So it always satisfy required. Treating required 
as having a value of true doesn't sound correct to me.

If we consider the error message that should be used, for the case of
forcing the user to check the box (eg, [x] I have read the agreement), 
it should say you must check xxx, which is quite different from the 
error message for required: you must provide xxx.

For the use case of forcing a checked check box, I think an CheckedValidator 
should be used, which can provide a much better default error message.

Not that it's an important, but just to see what others think.

validator, try PatternValidator([+|-]?(\\d)*[1-9](\\d)*) but then the
model has to
be a String, not a number.

Re: Empty ListChoice

 I believe that doing this causes the list to contain one empty, but 
 still selectable, element.  That is what I am trying to avoid--I just 
 want a plain empty list.  I'm starting to wonder whether empty lists are 
 considered to not be the Wicket way, as it seems like it should be 
 easier than this.  Does ListChoice *intentionally* not allow for an 
 empty list?  I expected to find something like 
 allowEmpty(boolean)...but no dice.
 

Have you tried my code? The list has no selectable entry.

Re: CompoundPropertyModel stops working when form validation fails.

 You were right Kent, thanks a lot! Calling clearInput() in the
 updating behavior really fixes the problem.
 
 What I miss now is why the CompoundPropertyModel breaks if the form is
 not manually reset by calling clearInput(). Is it a bug or a feature?
 :)
 

It's a feature. When the selection changes, the user might have entered
something into say a text field. Generally we don't want to lose that
input (because all you want to do may be to show or hide a certain component
depending on the selection), therefore it is saved and redisplayed to the 
user. By default it is clear only when the form is submitted and validation 
is passed successfully.

Re: CompoundPropertyModel stops working when form validation fails.

2007-10-05 Thread Kent Tong


Fabio Fioretti wrote:
 
 This is what I do, basically:
 1) Select a choice from the ListChoice;
 2) The form automatically fills with the data of the selected
 recommendation instance;
 3) Modify the data in the form so that validation will fail;
 4) Submit data -- validation fails;
 5) Select another choice from the ListChoice;
 6) The form doesn't get updated anymore (and keeps showing old data of
 the recommendation instance that failed validation)
 

I suppose you're using wantOnSelectionChangedNotifications() to trigger
the refresh? In that case it won't refresh any input entered by the user.
Validation plays no role here because such a form refresh does NOT invoke
the validation logic.

In order to refresh the data and erase what the user has entered, call
clearInput() on the form:

ListChoice recommendation = new ListChoice(recommendation, ...) {
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
protected void onSelectionChanged(Object newSelection) {
recommendationForm.clearInput();
}
};

Re: Page.detachModels() not working like it used to

2007-10-05 Thread Kent Tong


Dan Syrstad-2 wrote:
 
 Actually, Page.detach() is not callable from a JUnit test that uses
 WicketTester in 1.3.0beta3. It throws an exception:
 

I used your code and the test passed. Here is my test page:


html
body
test
/body
/html
public class Test extends WebPage {
public Test() {
ListView listView = new ListView(listView, Arrays
.asList(new String[] { a, b })) {

protected void populateItem(final ListItem item) {
item.add(new Label(labelWithDetachableModel, 
new
LoadableDetachableModel() {
protected Object load() {
return item.getModelObject();
}
}));
}

};
add(listView);
}
}


However, I really think your test case is broken. After startPage() returns,
the page has been detached. Why it passes on my computer is because
of your call to debugComponentTrees(). Therefore, you should really be
testing if the model is now detached. That's it. By checking the output 
you can be sure that the model was once attached.
