Re: PropertyModel with default null model object ?

[Per Newgro]

The code you provided should work. The NPEs comes from within the Panel? So 
can you give us an example how you access the model in the panel (with an NPE 
throwing component)?

Re: A few clustering questions

[richardwilko]

Thanks for the feedback.

You for anyone elses information, after following the instructions here:
http://docs.codehaus.org/display/JETTY/Session+Clustering+with+Terracotta

I found that I had to include the terracotta wicket module, as I was getting
terracotta exceptions without it.

But now clustering with terracotta seems to work, i can shut down the
instance im running on and my session is still valid on the other instance.

Testing with IModel mocks

[Per Newgro]

Hi *,

i try to test a page with some panels. They all get their models thru the 
constructor. The assigned models are always implementing IModel. At the 
highest level (page) there is a CompoundPropertyModel and all sub-components 
use a chain of PropertyModels. So far so good.

Now i try to use "easymock - interface api" to unit test the page. I assign 
the mock proxy (IMpdel) to the page and the sub-components should get their 
part of the model. The problem is that i can't find a way to give the 
sub-component an appropriate new IModel mock proxy, because on the original 
IModel only getObject() will be called. I don't have the abillity to 
distinguish by property expression.

Another way would be to use the class extension of easymock. But i would like 
to avoid it. Maybe someone solved this issue somehow with only usage of the 
easymock - interface api.

I hope i made my points clear.

Thanks

Re: Testing with IModel mocks

[James Carman]

I don't usually mock the actual models.  If I'm using a
LoadableDetachableModel, I'll mock the DAO or "repository" that the
model is using to find its data, but I never actually mock the model
itself.

Advisory question

[Martijn Lindhout]

Hi,

My web app background is from page oriented frameworks, and now while
using wicket, I find myself creating pages over and over.
I think I can miss many of them, because most of the time all I do is
adding an intelligent reusable component to it.

How do you guys handle this? Are you creating some basepage that is
suitable to contain more than one functional part of your application?
Or just create page by page?

But then i have to know the structures "under the IModel". Don't misunderstand 
me. I don't mean IModel and wicket related structures - i mean stuff from the 
IModel.getObject() instance (business object). And that's exactly what i try 
to avoid. I only try to access everything by the property name.

The background is the following:
In our project everyone has access to "business model instances". They simply 
get the interface and call the appropriate (get/set) method. We now tried to 
refactor some code and found that we have "deployed" business logic all over 
our panels and pages. Thats because you can access deeper model by the 
accessor chain. That sucks :-).

So i set up a little test project. In this the frontend components have only 
access to the "business interfaces". Within this you only have some methods 
defined like "doMyBusinessStuff()". There are no more getMyModel() and stuff 
like that. 
The accessible way for component binding is using a constant for property name 
in association with a PropertyModel. The real accessor methods 
(getter/setter) are departed in another "accessor interface" which can't be 
used from within the frontend (and thus is hidden for frontend tests to).

So i would like to ignore the "accessor interfaces" and only use the calls for 
the propertyname to return the appropriate IModel instance.

Thanks

Re: Advisory question

The nice thing about wicket is that it will give you freedom to choose
whatever you like.
You can create individual pages but if you markup is mostly the same
it is easy to to use markup inheritance from a single basepage.
You can also have just one page and replace panels as required.
It is all a matter of personal preference / application needs.

questions about Matt Raible's web framework comparison

[David Chang]

I just started migrating from Spring MVC to Wicket. I
found Matt Raible's interesting slides at this place:

http://static.raibledesigns.com/repository/presentations/ComparingJavaWebFrameworks-ApacheConUS2007.pdf

Matt's says 

1. regarding Bookmarking and URLs, "Wicket allows
pages/URLs to be mounted". What does this "mounted"
mean? Can somebody provide an example?

2. regarding Post and Redirect, Wicket has "flash"
support. What is "flash" support?

3. regarding Page Decoration, SiteMesh is not
supported or recommended for use with Wicket. This
worries me since I am Sitemesh fan. Can Sitemesh be
FULLY integrated with Wicket? Any Wicket user did
this?

Thank you so much for help!

you can mount a (bookmarkable) page on an url of your choice like:

application.mount("/login", LoginPage.class)

then the login page will be shown when somebody does http://host/login

If you have error or info messages that these are  shown over multiply
requests
So if you do a redirect you dont loose those messages.

Wicket just cleans the messages when they are rendered once (when ever that
happens)

I dont think sitemesh will be a great match for wicket at an time
It is really build for different  frameworks.
Wicket has for that build in support with Markup Inheritance and Panels

I guess if you are in mixed world (wicket and a jsp x framework) you could
try to mix that with sitemesh

I set model of radio on the group.

And thats logical, your code looks weird.
You cant set the model of a radio also on the group.
Then the submit will update the selected in the radio groups model.
Butthen the radio model is also uopdated. So that one is still
selected..

The nice thing about wicket is that it will give you freedom to choose
whatever you like.
You can create individual pages but if you markup is mostly the same it
is easy to to use markup inheritance from a single basepage.
You can also have just one page and replace panels as required.
It is all a matter of personal preference / application needs.

Re: Difficulty getting QuickStart

Maven requires some setup to get through your proxy server.  Look for
your MAVEN_HOME/conf/settings.xml file.  There's an example of how to
set up a proxy server.  That should fix it, I would think.  The
central repository is working for me. :)  Good luck!

It means to attach a relative URL to the page, e.g. mounting LoginPage
to "/login" means you can get to the LoginPage via the URL
http://foo.com/myapp/login. If you don't mount the page, Wicket
generates a URL that's not as nice.

A common pattern is to post a form to one page, then redirect to the
next page. If your post handling code needs to send a message to the
user (e.g. "Your order successfully placed!"), it stores the message in
a well-known place in the session. Then when the subsequent page
renders, it looks for a message in the session. If one is there, it
displays it and removes it from the session so it is only displayed once.

In other words, it's a way to "flash" a message to the user.

Look into Wicket markup inheritance. One think I disliked about Sitemesh
was the limited ability of each page to affect what was going on in the
decoration. With Wicket's markup inheritance, the decoration is just
rendered by your page's superclass, so you can have full programmatic
control over it by calling or overriding methods in the base class. Much
more powerful than Sitemesh, IMHO.

JS/CSS references different in Jetty versus Tomcat

[Scott Sauyet]

I'm having a problem with different behavior when my Wicket application 
runs on Jetty versus on Tomcat, and I'm wondering if anyone has a 
suggestion as to why.


I'm running Wicket 1.3.0 inside Jetty 6.1.8 or Tomcat 5.5.26.

The only place I'm seeing this right now is the second and subsequent 
pages of a PageableListView.  This is one of the few places where I 
don't have clean URLs, and I don't know if that's a cause.  (Aside: is 
there a way to get cleaner URLs in pages with PageableListViews?) 
Almost every page the user sees is a BookmarkablePage, but this one 
isn't, so maybe that's the difference; I just don't know.


A search form with a GET method is on every page.  When searching for 
the term "acct", the form redirects to a BookmarkablePage with a URL 
that looks like:


http://jetty-host:port/app/FindTagByName/tagname/acct/

and on that page there are Javascript and CSS elements with SRC and HREF 
attributes like this:


 ../../../css/standard.css

Links in the PagingNavigator point to pages like this:

http://jetty-host:port/app/?wicket:interface=:6:1:::

and the SRC/HREF attributes here look like this:

css/standard.css

Which works fine.  But when running on Tomcat, starting from here:

http://tomcat-host:port/app/FindTagByName/tagname/acct/

the links are fine, and the subsequent pages have URLs like

http://tomcat-host:port/app/?wicket:interface=:3:1:::

All my SRC/HREF attributes here are wrong, pointing to the Tomcat 
directory and not my web application:


../css/standard.css

Anyone have a suggestion as to what I might be doing wrong?

Thanks,

  -- Scott

Johan,

Thank you for your information. 

If I want an entire site to have nice URLs, I have to
MANUALL add the line such as this

application.mount("/login", LoginPage.class)

for each WebPage component of this application?

David

yes but you also can mount 1 package is 1 go.
But are all pages that you make accessible directly from the outside world?
So they should really all be bookmarkable?

It depends what you want to achieve.
For simple things just use IndicatingAjaxButton/Link from

Jonathan Locke:
Wicket.Ajax.registerPreCallHandler(onStartAjax);
Wicket.Ajax.registerPostCallHandler(onStopAjax);
Wicket.Ajax.registerFailureHandler(onStopAjax);

then just hide and show your indicator in onStartAjax() and onStopAjax() and
every single AJAX request on your site will magically spin that little
wheel.

way to traverse / get all form validators

[michalb_cz]

Is there some way how to traverse all validators which are associated (added
through the add(IValidator) method) with the form? I look for something like
get(IValidator) [like List.get(Object obj) method] or List
getValidators() methods on Form component

validation: Wicket does the right thing? Or right tool?

[David Chang]

I am migrating from JSP+Valang+...+SpringMVC to Wicket
and am also still evaluting it. So far so good until I
saw this instance about using Form Validator to
validate two related form fields.

Problem (p81-82, book Enjoy Web Development with
Wicket, PDF version only):

Suppose a postage calculation form has two fields that
accept weight and patron discount code. For a
particular patron p1, you will never ship a package
that is weighted more than 50kg. Here is the code from
the book:

public class LightValidator extends
AbstractFormValidator {
  private TextField weight;
  private TextField patronCode;

  public LightValidator(TextField weight, TextField
patronCode) {
this.weight = weight;
this.patronCode = patronCode;
  }

  public FormComponent[] getDependentFormComponents()
{
return new FormComponent[] { weight, patronCode };
  }

  public void validate(Form form) {
String patronCodeEntered = (String)
patronCode.getConvertedInput();
if (patronCodeEntered != null) {
  if (patronCodeEntered.equals("p1")
  && ((Integer)
weight.getConvertedInput()).intValue() > 50) {
error(weight);
  }
}
  }
}

I have the bad feeling about this way of validation

1. It is too much coding. Anybody used Valang in
Spring Module? By using Valang, the validation code is
much clean and a lot fewer and you dont need to create
a class simply for this simple validation.

2. Valang covers both client AND server-side
validation. Please note that client-side validation is
equally important as server-side's. I feel it is a
must for web apps in terms of user experience.

3. In Valang + Spring MVD, you have all the validation
code for a form in one place in stark contrast to
spreading it in "controller" code as in Wicket and
mixing validation code with visual manipulation code.
Valang's way is much easier to understand and
management.

So in terms of elegance, productivity, management,
..., I am not sure Wicket's is right.

Can Wicket provide a better solution? 

I would like to share my concern regarding the
Wicket's WebPage, where you put a form's code for some
visual aspects, validation, ajax, etc. in one place. A
big object. I feel it is too ambitious and it looks
like spaghetti code and mixes concerns/modules in one
place. Comment?


I am very new to Wicket and don't know the best ways
of using Wicket. I love to hear from expereinced
users/guru here.

Thanks for your input!

Warm regards,

David

Re: What is session.dirty() for?

[Matej Knopp]

Hi,

session.dirty() should be invoked when the session object has changed,
so that wicket changes the http session attribute to make cluster
replicate the session object (assuming you're running in clustered
environment).

I think the only case when you need to call dirty() yourself is when
your application has only stateless pages and you have a statefull
session object that you need to replicate accros cluster. But IMHO
that's not very common usecase.

Could you please elaborate what you mean by "session object has changed"?

Let's say I have some variables in my session. If these variables
change, do I have to call session.dirty?

I think you'll find the Wicket team has very strong aversion to doing
things declaratively rather than with Java code. The problem is that
with declarative approaches, once you step outside of the use-cases
envisioned by the designer of the declarative system things become much
more difficult.

Wicket doesn't come with a client-side validation framework by default;
however, the validators have an opportunity to participate in the
component rendering, so it wouldn't be too tough to create your own set
of validators that also rendered the appropriate Javascript to do
client-side validation.

A Wicketer would view it differently: in Valang+Spring MVC you have Java
code for your controller and validation "code" in XML, whereas in Wicket
it's all in Java code.

That said, it probably wouldn't be too hard to implement a FormValidator
that accepted valang syntax and applied it to a form.

Weird. Your experience is exactly opposite to mine. I found Spring MVC
to be hopelessly scattered: declarations in XML, controller code in
Java, view code in templates. In Wicket, I can create self-contained
components, each including all the functionality, markup, validation,
JS, etc. it needs to get along in the world. I can then stitch these
components together into pages that can be re-jigged and reorganized
very quickly.

It feels to me like Wicket allows me to work at a higher level of
abstraction, while with Spring MVC I was always down in the weeds
dealing directly with the request/response cycle.

That was exactly it.  Thank you.

Unfortunately, this issue has not been resolved as of Wicket 1.3.3. 
There was a bizarre note at the end of that issue from Al Maw that it 
had something to do with having an "index.jsp" page in the application. 
 Sure enough, when I removed that page, it seems to work fine.


The client wanted that "index.jsp" for consistency with the application 
that I'm replacing.  I will find out exactly how important that is.  I'd 
really rather not go with the "app/*" route unless necessary.  But I'm 
curious if anyone has figured out a solution to the underlying problem.


Thanks again, Jeremy.

Al,

I'm CC'ing you because in the last notes I saw for issue 1205 you were 
off to try to fix this.  Did you ever get a useful test project to 
duplicate the error?  If not, I can try to create something, although 
I'm not much of a Maven user.  Just let me know.

[Jonathan Locke]

don't agree at all of course.  ;-)  and i'm going to give you about the same
stock answer i always give: if you're repeating yourself, stop doing that.

writing redundant form code?  writing redundant validators?  think.  use OO
design patterns.  it's amazing what you can do with objects.  at thoof i
never wrote validation code.  we adopted the sun constraint library more or
less as described in this video:

Re: validation: Wicket does the right thing? Or right tool?

[David Chang]

>>The problem is that with declarative approaches,

I would like to think practical. How many such

that accepted valang syntax and applied it to a form.

I really want to see such a thing in place.
Auto-generation of client-side validation code, IMHO,
is a much needed thing. At least, Wicket should have
this capability. It would be nightmare to wrtie
validation twice: one for the WebPage, one for
client-side validation.

I found Spring MVC to be hopelessly scattered:

evaluating. 

One thing I have is really the opposite to your
experience. I feel this "scatter" is not hopeless; but
it is a nice separation of concerns. Think about it. I
have no objection to puting everything in WebPage, but
these different concerns should be separated in Wicket
somehow, code should look clean and good...

Thank you for sharing your thought and experience,

Wicket : Navigation Test Case Failure

[iwessels]

Hello all, 

I am trying to write a test case to simulate that when the user clicks on a
button, they are navigated to a new page.

// Test Case 
public void testProgramPageNavigation() {
   WicketTester tester = new WicketTester();
   FormTester formTester = tester.newFormTester("programForm");
   formTester.submit("programButton");
  
   // this line fails (expected NewProgramPage but was ProgramPage)  
  tester.assertRenderedPage(NewProgramPage.class);
}

// Program Page
public class ProgramPage extends WebPage {
 
 public ProgramPage() {
Form programForm = new Form("programForm");

programForm.add(new Button("programButton") {
public void onSubmit() { 
   setReponsePage(NewProgramPage.class);
}
}

add(programForm);

  }
}

Any help would be much appreciated

Re: Wicket : Navigation Test Case Failure

[Maurice Marrink]

Do you do tester.startPage(ProgramPage.class) before you use the FormTester?
You should get a different error if you didn't but i don't see where
you tell wicket which page to load, so i am just checking.

Re: validation: Wicket does the right thing? Or right tool?

[Jonathan Locke]

auto-generation of anything is a horrible idea.  it's a computer-driven
violation of the DRY principle and you'll get what you deserve.  there are
pretty much always smarter approaches than code generation.

you ought to be able to use wicket to create a constraint driven validation
system that does:

 - client side validation
 - server side validation
 - database validation
 - automatic limits unit testing

we did the last 3 at thoof, and while the client-side validation was not a
goal, it should be possible to integrate and drive a JS validation lib using
the same annotations.

Re: Wicket : Navigation Test Case Failure

[Izak Wessels]

You are correct, I omitted it, due to it being done in the superclass, but
tester.startPage(ProgramPage.class) is def being called

I just realized that you may not be clear on the role of FormValidators
in Wicket. A FormValidator is only used when the validation of one field
depends on the value the user entered for another field. The vast
majority of validation uses only field-level validators, which are much
less verbose than FormValidators:

  new TextField("name").setRequired(true);

  new TextField("ccNumber").add(new CreditCardValidator());

My current Wicket application (~35,000 LoC, ported from SpringMVC BTW,
so I speak from experience!) has no more than a handful of
FormValidators.

In this case I think "separation of concerns" is just a nice way of
saying "lack of cohesion/encapsulation". I *want* my validation to
follow my component around, especially when I have a form composed from
several re-usable panels. 

Here's a real-world example. In my app we have a component that captures
credit card info (card number, expiry, etc). It's not a form, just a
Panel with a bunch of form components on it. We re-use this panel in
several very different forms, each of which has various additional
fields.

Each time this panel is re-used, I just drop it into the form like this:

  form.add(new CreditCardPanel(ccModel));

I don't have to add the CreditCardValidator to each one of these forms.
It comes pre-wired in the CreditCardPanel.

> have no objection to puting everything in WebPage, but

> somehow, code should look clean and good...

Very few Wicket applications put "everything in WebPage". Pages are
usually componentized into various Panels, which in turn can be composed
from other Panels and components. Each of these panels/components can
come with their own validators, as well as with other contributions to
the page such as JS, CSS, etc.

Re: Bulk form field edits - possible? - RESOLVED

[Ritz123]

Thanks guys for the response.

Just to complete the thread...

Like you guys mentioned, yes it is possible, like Igor said if the form or
its children (DataView or any other related view) has the model (e.g.
CompoundPropertyModel) on the form objects, the model will be updated on
form submission and hence you will have all the fields on the page updated.

My requirement was to work with an existing ShoppingCart - so I had to
create transient POJO to hold form fields and on form submission take the
new values and pass it on to the ShoppingCart.

Pro-Wicket book has this covered in its CheckoutPage example (Chapter 3) in
case someone needs details.

I will typically just put those fields on the form itself instead of
creating a separate pojo/bean.  For what it's worth...

RE: RTFM messages

[Andrew Broderick]

Maybe that is the problem - 10% of the people give 90% of the answers. This 
means they have less time to explain stuff in detail. However, you are right - 
the answers are fast (within minutes) and, even if not complete, usually give 
enough information to find the right place to dig.

I do in fact search all the sources I can find before asking the list, 
including: wicketstuff.org, Google (Nabble has excellent Wicket stuff), the 
list archives, and Wicket In Action.

As for explaining it to new users myself, I would if I knew the answer! I am 
still a newbie, although if I have anything to say about it, we will be using 
Wicket for a long time to come, so I will eventually become expert at it. The 
code is of extremely high quality, and one taste of using it is enough to make 
me never want to touch another front-end framework again. Good work all.

I have to add here that I have asked quite a few questions on this list, and
always received a plethora of helpful information - 90% of the time from
core contributors.  This list is the best open source mailing list I have
ever subscribed to or asked questions on.  Many times I have sent emails to
other user lists, even active ones, with questions I could not find the
answer to, and never received a response - at all.

The entire Wicket community is very friendly and helpful.  And, honestly, if
I asked a question for which there were an answer in the javadoc - I would
appreciate Martijn's answer - it would remind me to look for it myself
(which we sometimes get so busy we forget) - and it has much better longterm
benefit than giving a direct answer, or even copy-and-paste the javadoc.

Of course, Andrew, you always have the option of explaining it to the new
user, too - that might help with the wide spread adoption.  I see from your
message history that you love Wicket like the rest of it, and have received
many fine answers from the same core committers that you criticize here.
Just saying - it goes both ways.

THANK YOU WONDERFUL WICKET COMMUNITY AND ESPECIALLY THE CORE COMMITTERS
(Igor, Martijn, Johan, and everyone)

Re: PropertyModel with default null model object ?

[smallufo]

Yes .
In the WebPage , I add MyPanel like this :

myPanel = new MyPanel("myPanel" , new PropertyModel(this , "myobj"));
myPanel.setVisible(false);
myPanel.setOutputMarkupPlaceholderTag(true);
add(myPanel);

And in the MyPanel :

public class MyPanel extends Panel
{
  private MyObj myObj;

  public MyPanel(String id , IModel model)
  {
super(id);
this.myObj = (MyObj) model.getObject();

add(new Label("xxx" , myObj.getFieldX.toString()));
add(new Label("yyy" , myObj.getFieldY.toString()));

  }
}

Because myObj passed to MyPanel is initially null ,
In the MyPanel construction time , myObj.getFieldX , myObj.getFieldY will
throw NPEs here...

I don't know how to solve it .

This is the problem. Don't store the instance in the panel. Use the provided 
model. The Labels can get their data by a PropertyModel related to that 
model.
 public class MyPanel extends Panel
 {
  // removed while not required private MyObj myObj;

   public MyPanel(String id , IModel model)
   {
 super(id, model); <-- use this constructor
 // removed while not required this.myObj = (MyObj) model.getObject();

 // instead add(new Label("xxx" , myObj.getFieldX.toString()));
 add(new Label("xxx" , new PropertyModel(model, "fieldX")));
 // instead add(new Label("yyy" , myObj.getFieldY.toString()));
 add(new Label("yyy" , new PropertyModel(model, "fieldY")));
   }
 }

You simply wire the models together. So a model related to view can't be null 
(instanciated in panel self). That's what i mean if i always say "path to 
data". It's a description which properties have to be used to get the data. 
So the underlying business object can be null. The behavior if a null will be 
return will be determined by the component. A label for instance is 
displaying simply a blank. Textfield to.

Pros and cons of WicketBench

[Frank Silbermann]

 
When I was developing in Wicket 1.2 I used Jbuilder 2006; it was what
the employer provided.  Other developers, however, use Eclipse for their
(non-Wicket) projects, and Jbuilder 2007/8 are Eclipse-based, so I
figured might might as well start my Wicket 1.3 experiments using
Eclipse.

What are the pros and (if any) cons of using the Wicket Bench plug-in?
Is it worth setting up if all I'm really going to be doing is (perhaps)
to upgrade a Wicket 1.2 application to Wicket 1.3?

Re: Can the UploadProgressBar not submit if the file field is blank?

[Matthew Young]

>Can you just mark it as required?

It's not the validation part I have problem with. I want to prevent the
UploadProgressBar from showing up when the field is blank and show a
javascript alert in that case.  There is no need to submit to the server.

The UploadProgressBar installs an 'onsubmit' event handler to show itself.
It's installed by adding a AttributeModifier to the form. Is there any way I
can put stuff *in front* of its javascript?  So I can have something like
this:

"if (field.value == null || field.value==""){alert("You must choose a file
to upload");return false;}[the rest of UploadProgressBar stuff]"

Re: PropertyModel with default null model object ?

[Martijn Dashorst]

You can nest models and use a model as the value for a PropertyModel.
A PropertyModel knows how to cope with null values as it will return a
null. Components and the label component in particular will render an
empty string when the model value was found to be null.

So nest or chain your model inside PropertyModels:

add(new Label("xxx", new PropertyModel(model, "fieldX")));
add(new Label("yyy", new PropertyModel(model, "fieldY")));

Read the model documentation on the wiki [1]. Try to understand it and
commit it to your brain. Print the page, and put it under your pillow
at night. Read it while on the toilet, pin it to the side of your
monitor, stick it to your rear view mirror, print it on transparent
foil and stick it to the inside of your glasses.

Re: Pros and cons of WicketBench

[Igor Vaynberg]

for me there are two cool aspects to wicket-bench:
1) refactor support - if you rename a class that extends Component it
will find any matching .html and .properties file and rename those
also

2) editor - wicketbench replaces java editor with a tabbed editor that
lets you quickly switch between java/html/properties files when you
open a class that extends Component. very handy.

however, it does have its problems. eclipse' java editor is not built
with embedding in mind, so once you start using (2) you will miss out
on such useful things as "mark occurences", double clicking the left
border to set a breakpoint ( right clicking still works ), ctrl
clicking into a class wont always work, etc.

i think the idea is awesome, too bad eclipse makes it so hard to implement :(

[ANNOUNCE] Apache Wicket 1.4-M1

[Frank Bille]

The Apache Wicket team is proud to announce the availability of the
first milestone release of our first java 1.5 Wicket version: Apache
Wicket 1.4-m1.

Eager people click here to download the distribution, others can read further:

http://www.apache.org/dyn/closer.cgi/wicket/1.4-m1

We thank you for your patience and support.

The Wicket Team

=== Apache Wicket ===

Apache Wicket is a component oriented Java web application framework.
With proper mark-up/logic separation, a POJO data model, and a
refreshing lack of XML, Apache Wicket makes developing web-apps simple
and enjoyable again. Swap the boilerplate, complex debugging and
brittle code for powerful, reusable components written with plain Java
and HTML.

You can find out more about Apache Wicket on our website:

http://wicket.apache.org

=== This release ===

The Apache Wicket team is proud to announce the availability of the
first milestone release of our first java 1.5 Wicket version: Apache
Wicket 1.4-m1. This is the first release with java 1.5 as a minimum.
Not everything has been converted to java 1.5 yet but we are getting
there.

=== Migrating from 1.3 ===

If you are coming from Wicket 1.3, you really want to read our
migration guide, found on the wiki:

http://cwiki.apache.org/WICKET/migrate-14.html

=== Downloading the release ===

You can download the release from the official Apache mirror system,
and you can find it through the following link:

http://www.apache.org/dyn/closer.cgi/wicket/1.4-m1/

For the Maven and Ivy fans out there: update your pom's to the
following, and everything will be downloaded automatically:

   
   org.apache.wicket
   wicket
   1.4-m1
   

Substitute the artifact ID with the projects of your liking to get the
other projects.

Please note that we don't prescribe a Logging implementation for
SLF4J. You need to specify yourself which one you prefer. Read more
about SLF4J here: [http://slf4j.org]

=== Validating the release ===

The release has been signed by Frank Bille, your release manager for
today. The public key can be found in the KEYS file in the download
area. Download the KEYS file only from the Apache website.

http://www.apache.org/dist/wicket/1.4-m1/KEYS

Instructions on how to validate the release can be found here:

http://www.apache.org/dev/release-signing.html#check-integrity

=== Reporting bugs ===

In case you do encounter a bug, we would appreciate a report in our JIRA:

http://issues.apache.org/jira/browse/WICKET

=== The distribution ===

In the distribution you will find a README. The README contains
instructions on how to build from source yourself. You also find a
CHANEGELOG-1.4 which contains a list of all things that have been
fixed, added and/or removed since the first release in the 1.4 branch.

Please don't. These examples are *OLD* and not maintained much. We
have been telling folks to not look at those examples for over a year.
Wicket stuff is the place to look for the examples. For
debugging/learning/running corporate demos you really should download
the examples and run them locally.

If you subclassed the Session class and your attributes are properties
of the subclass.

But you are required to call session.dirty() only if your pages are
stateless and your application is deployed on cluster.

Re: Can the UploadProgressBar not submit if the file field is blank?

I solve this problem by putting an 'onclick' handler on the Submit button to
check for blank input.
