My first Wicket question

[David Chang]

I just started to learn Wicket.

This question may seem naive to many people and please
forgive me.

a WebPage component is created for each session and
its data members are not shared by different sessions.
Correct?

Thanks!

p.s. Where can I find a useful FAQ list to answer
questions similar to that? Thanks!

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!

David

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?

Regards,

David

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

[David Chang]

>>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.

I would like to think practical. How many such
unexpected situations would happen? Besides, you can
always code extra validation in Java in controllers
using things such as Wicket's form validators.



>>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.

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.



>>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.

I dont have any real experience yet. It is mere my
observation and thinking. I am learning but still
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,
which is immensely helpful!

Regards.

[David Chang]

Eelco,

Thanks so much for your input! I am still seriously
learning Wicket now and will see if I will change my
mind.

BTW, what is the best Wicket example website? I often
have many questions when reading tutorials with simple
examples. I wonder Wicket can do or how do more
callenging/complex situations that I can easily handle
with Spring MVC.

Regards,

David

[David Chang]

Eelco,

I am reading the PDF version of the book called Enjoy
Web Development with Wicket. Basically it is a good
one with many interesting examples, but these examples
are simple and keep me wondering whether Wicket can
handle other more complicated situations. 

I feel this book does a good tutorial job, but it has
many how-tos and lacks whys (the Wicket design ideas).
I feel switching from JSP+Spring MVC to Wicket it is
crucial to know those whys to fully appreciate or
effectively use Wicket.

How is your Wicket in Action?

Thanks,

David

Pre-built wicket sample app for a starter to copy?

[David Chang]

Hello, I have a web project to do and this time I am going to do it with Wicket 
instead of Spring MVC. And I need your input.

The tools I plan to use include Wicket, Spring, Hibernate, Acegi, and 
Displaytag.

I recall when I started my first Spring project, I copied Matt Rabile’s example 
application and started to modify it, which got me off the ground pretty 
quickly.

For my Wicket project, I hope to see a similar pre-built or semi-built Wicket 
application that uses the above tools for me to quickly start without spending 
much time to figure out the “optimal” organization of files and directories.

Any idea or suggestion?   Thank you!

Cheers!

Any easy way to do client-side javascript-based validation with Wicket?

[David Chang]

I am now reading the book "Wicket in Action" to learn about Wicket. The more I 
read and the more I like it!

I did a few projects with Spring MVC in the past. In these projects, I defined 
form field validation rules in an XML file and Spring adds both client side and 
server-side, which I think is quite helpful.

I just want to know how to do the same thing in Wicket. The validation rules 
dont have to be in an XML file and they can be in Wicket's Java files, but I 
hope Wicket can generate client-side validation.

Please dont argue with me about the good or bad things about client-side 
validation. I simply want to know whether Wicket can do it or how to it, as 
well as any attempt in this regard. 

Thanks so much for your help!

Cheers!

Re: Any easy way to do client-side javascript-based validation with Wicket?

[David Chang]

Thanks for your input, but I am looking for something different.

In Spring MVC, I can use Spring Modules' Valang Validator to define validation 
rules in applicationContext.xml for a form bean. Then Spring generates both 
client- and server-side valudation. This write-once approach is very appealing. 

I am not planning write validation rules in Wicket's Java components and write 
Javascript-based client validation again in markup.

Cheers!

RE: Any easy way to do client-side javascript-based validation with Wicket?

[David Chang]

Frank, thanks so much for your input. It seems your jQuery validation plugin is 
a cool tool.

Does it mean that by using Wicket AND your jQuery validation plugin I only have 
to write validation rules ONCE (not write second time for the client side 
validation)? Is it correct? If it is true, I am eager to donate after tests:-)

Warm regards.

RE: Any easy way to do client-side javascript-based validation with Wicket?

[David Chang]

Jeremy, thanks so much for the input. I will look at it later. 

I feel that, in addition to server-side validationi, the client-side validation 
is much needed since it reduces lot of network traffic and server workload for 
a busy website. 

I have been doing consulting for many years and I do see customers really like 
client side validation. In my experience, that need is an order from the God 
and we, as programmers, have to deliver. I am surprised that no mature solution 
in this regard can be found from the Wicket or related projects.  

Still, Wicket is great!!!

Cheers!

How to receive digested emails once a day from this mailing list ???

[David Chang]

I am new to this mailing list and I like it very much. I like the active 
community and the questions and answers, but I prefer to receive all the emails 
combined together in a single email once a day. I want to stay in the loop.

I tried user-digest-subscr...@wicket.apache.org and there is no such list.

Do you happen to know how I can do this? I looked at the Wicket project website 
but failed to find such a way.

Thanks for your help!

Error filterStart -- how to know what caused tomcat start failure?

[David Chang]

Hello, I am in the process of learning Wicket and testing different things. One 
of the biggest problems so far is that when starting Tomcat, I often get the 
following error message:

SEVERE: Error filterStart

AND Tomcat gives no detail what cuased the problem

Any way I can make Tomcat produce more information about the cause of the 
failure?

Thanks!!!

Re: Error filterStart -- how to know what caused tomcat start failure?

[David Chang]

I googled a lot but failed to find satisfactory answers. I just find a way to 
make tomcat to produce more error info than simply

May 30, 2009 12:06:57 PM org.apache.catalina.core.StandardContext start
SEVERE: Error filterStart
May 30, 2009 12:06:57 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/wic] startup failed due to previous errors

I am learning from the book Wicket in Action. The funny thing is that the new 
stuff is no problem, but the tomcat error is.

Re: Error filterStart -- how to know what caused tomcat start failure?

[David Chang]

Vitek, you are right. Under tomcat\logs directory, one type of logs called 
localhost contains more info than what tomcat start screen reveals.

Thanks for the pointer.

Large internet rich UI Wicket websites?

[David Chang]

I am still learning Wicket. The more I read from <>, the more 
I like it.

The backgound for this request is that we may use Wicket for a large 
highly-active website. 

Cheers!

Martin, I looked at the list and it seems none of them meets what I said about 
large rich ui Wicket website. Likely I am ignorant. Please enlighten me. By 
large, I mean something similar or close to amazon.com or ebay.com that have a 
large number of concurrent users. Which Wicket website in your knowledge seems 
to the largest one?

Thanks!

Re: Large internet rich UI Wicket websites?

[David Chang]

Jeremy, thanks for your input. I don't quite understand the side note in your 
reply. For a large website such as Amazon to work, there should absolutely be 
different technologies/tiers, tuning, security, and other considerations. The 
basic question is whether a framework is up to that task and whether there is 
evidence in reality.

Still back to my original question, any there any large Wicket website out 
there? Wicket people have to face it, me too, if I am going to use it.

Wicket Bench website is down

[David Chang]

I am hoping to download the Eclipse plugin and followed the link from the 
Wicket website, but the site is down.

http://www.laughingpanda.org/mediawiki/index.php/Wicket_Bench

Any other place to download this plugin?

Thanks.

Serialization of a page with a long and dynamic list of records

[David Chang]

I am learning and evaluating Wicket now and have a question to ask.

I have a page that displays a long list (say 2000) of records. This page is 
dynamic, which means the list of records may change for each reload. I 
understand that I should use loadable detachable model. My question is: does 
Wicket serialize each page reload with all the records on a particular reload?

Thanks!

Questions about Wicket sessions

[David Chang]

Reading <> to learn Wicket, I understand that sessions are 
not thread-safe. I have the following questions about a Wicket app:

1. If I open another tab on the same browser (IE or FF), visitor activities on 
the same Wicket app are considered in the same session?

2. If I start IE or FF in another window, visitor activities on the same Wicket 
app are considered in the same or different session?

3. If dirty() is called within a method of custom session object, then it is 
the developer's responsibility to implement dirty() to synchronize with other 
clustered web servers, correct?

Thanks!

Re: Questions about Wicket sessions

[David Chang]

Another question: 

By default, Wicket's SessionStore stores older pages to a temporary directory. 
It is stored as files, correct? In case of a large website demanding high 
performance, it should be stored in a high-performance database, correct?

Thanks!

So if I dont use clustered web servers, custom methods on a custom session 
object do not need be "synchronized". Put it another way, Wicket session is 
thread-safe in case of a single web server. Correct?

Cheers.

the effective ways of wicket models to access database

[David Chang]

Hello, I am reading <> to learn Wicket. The example on Page 
99 is about teaching detachable models. Here it goes:

---
public class CheeseModel extends Model {
private Long id;
private transient Cheese cheese;
public CheeseModel() {
}
public CheeseModel(Cheese cheese) {
setObject(cheese);
}
public CheeseModel(Long id) {
this.id = id;
}
@Override
public Object getObject() {
if(cheese != null) return cheese;
if(id == null ) {
cheese = new Cheese();
} else {
CheeseDao dao = ...
cheese = dao.getCheese(id);
}
return cheese;
}
@Override
public void setObject(Object object) {
this. cheese = (Cheese)object;
id = (cheese == null) ? null : cheese.getId();
}
@Override
public void detach() {
this. cheese = null;
}
}
---

I would like to know how dao is obtained as indicated as follows:

CheeseDao dao = ...

Use a locator pattern? Or should I let CheeseModel extend a custom model in 
which dao is set via Spring? Does the latter way create more memory footprint? 
What are the effective ways of getting DAO avaiable to wicket models?

Thanks for your input!

Cheers!

Re: the effective ways of wicket models to access database

[David Chang]

Martin and all, thanks for your input.

>>You can use spring to inject the service, using @SpringBean and
calling in the constructor InjectorHolder.getInjector().inject(this);
(or use salve)

You mean add a member to this CheeseModel class and use @SpringBean to inject 
it? From reading this book, I know it works. How about creating a super custom 
model (implements IModel) which has DAO ready and other classes such as 
CheeseModel simply extends it?

What do you mean by "salve"?

Thanks.

Why just 26 tricks?More please..! 

I feel the learning curve for Wicket is kind of tall and more tricks can

How Wicket's big concepts/objects work together and in what order?

[David Chang]

Hello, I am learning Wicket now and feel a bit confused by the new concepts in 
Wicket regarding how they work together and in what order.

The big concepts I am talking about include:

Application
Session
Request
RequestCycle
RequestCycleProcessor
RequestTarget
SessionStore
Request
Response

Suppose I have a simple page with just one Wicket label. A user requests this 
page. I would like to know how the above objects/concepts get involved and in 
what order.

If it needs too much description, then forget it. If it does not take too much 
of your time or you want to refresh yourself by give me an explanation, I 
really appreciate it.

I want to be a good Wicket programmer.

Thank you!

Re: How Wicket's big concepts/objects work together and in what order?

[David Chang]

Igor, thanks for the tip. I read that wiki page "The Life-Cycle of a Wicket 
Application". The page has useful info but it is still lacking. It does not 
mention RequestCycleProcessor, RequestTarget, or Response objects. Can any 
Wicket expert update this page?


Have a better understanding now but hope to have more explanation.

Re: How Wicket's big concepts/objects work together and in what order?

[David Chang]

Jeremy, thanks for the good tip. It makes sense, though not the best way. The 
more I read about Wicket, the more I like it:-) Just hope to know every detail. 
Wicket is a great tool but learning curve is tall.

Where can I find this Wicket application?

[David Chang]

Hello,

I am reading Wicket-related stuff on the net and came across this Wicket 
discussion thread:

http://osdir.com/ml/users-wicket.apache.org/2009-05/msg01196.html

In the response, "my wicket-advanced example application" is mentioned. 

I would like to know where I can find this application?

Thanks!

avoid setters / getters by using ?

[David Chang]

Hello,

I have Wicket+Spring application. It has a service object which has a few DAO 
members. I can use Spring's autowiring to avoid mentioning the DAO dependencies 
for the service bean. However, in the Java program for the service bean, I 
still have to add setters and getters for each DAO member, which I don't like. 
How can I avoid these setters and getters? Using AOP? Any examples?

I understand that this question is not strictly a Wicket, but I definitely want 
to ask my Wicket friends here.

Thank you!

Re: avoid setters / getters by using ?

[David Chang]

Martin,

Thanks for your input. My intention is how to get rid of these boring 
setters/getters from service beans that are usually generated only for the 
purpose of spring-injection.

Cheers!

Can Wicket automatically remove beginning and trailing spaces in a text field?

[David Chang]

How to set it up in a Wicket application? I would like to set it up in the 
application level.

Thanks!

Re: Can Wicket automatically remove beginning and trailing spaces in a text field?

[David Chang]

For this to work, I have to overwrite this method either for each form or write 
a custom class extending FormComponent. Correct?

If yes, then it is not what I hope to get. I dont want to do it for each form 
or a custom class.

I came from Spring MVC camp. This task is very easy in Spring.

Cheers.

How to store/load strings shared by many (but not all) pages?

[David Chang]

I am reading <> and have this i18n/i10n-related question :

Suppose that I have a string that is used on multiple (but NOT ALL) pages. One 
solution is that I can put this string in the property files for each page on 
which the string is used. 

Any other better solutions?

Thanks for your input!

Start a panel, border, or page with an XML declaration?

[David Chang]

Hello, I am reading <>. The Tip on page 291 says "it is good 
practice to start your panels and  borders (possibly your pages) with an XML 
declaration to force Wicket to work with them using the proper encoding". 

Does this mean that starting a panel, border, or page with something such as

Move shared wicket components to a base page?

[David Chang]

I have two wicket pages, both of which extend a base page. In the first 
version, each page used a wicket componet as follows:



In the second version, I moved the above markup to the base page. However, I 
always got this error from wicket:

WicketMessage: The component(s) below failed to render. A common problem is 
that you have added a component in code but forgot to reference it in the 
markup (thus the component will never be rendered).

I checked the base page's code and markup many times. It is there. 

Can someone tell me whether it is doable in wicket and what went wrong?

Thanks for your input!

How to list files by name in Eclipe's Package Explorer?

[David Chang]

Hello, 

I am using Eclipse for devleopment. The files in its Package Explorer are 
listed by extensions: java files first. This is good for non-wicket 
development. Now each page's java and markup files are in the same directory 
and I hope to see them naturally stay together, which means making Package 
Explorer to list files by name.

How to do this?

Thank you!

Re: Move shared wicket components to a base page?

[David Chang]

Hello Igor,

I have quickstart installed and looked at it everywhere. It has two application 
clsses only: WicketApplication and HomePage. I am unable to find anything 
related to my question.

Did I miss something?

Thanks!

Re: Start a panel, border, or page with an XML declaration?

[David Chang]

Phil,

Thanks very much for your reply. By XML declaration, you mean something like:



Correct? I found this piece and it may be interesting to all:

http://learningtheworld.eu/2008/farewell-xml-declaration/

>>I prefer to include it in my source, and then have
Wicket strip it out at the last moment - at least when I'm forced to
be IE6 compatible

I am interested in this solution. Could you please share with us the detailed 
how-to?

Regards.

Tor, you are right. I found a coding error in my program. Yes, this whole thing

Re: How to list files by name in Eclipe's Package Explorer?

[David Chang]

Thanks for your input! It seems to does the trick. The only thing I don't like 
is that it shows all the levels of directories, which is unnecessary and makes 
the Navigator view quite wide.

links on the page after invalidating the session

[David Chang]

I am reading the book: Wicket in Action.

The first sentence of the Note on page 274 reads:
-
Always set a bookmarkable response page after you invalidate the session.
-

My understanding is that if this page has any Wicket-generated links, it MUST 
be bookmarkable links too. 

Correct?

Thanks!

A question about the book WIA

[David Chang]

I am reading the book: Wicket in Action.

The first sentence of second paragraph of page 273 reads:
-
In the UserPanel, we created a model that extends LoadableDetachableModel for 
representing the current user (if any).
-

In this chapter (Chapter 11 Securiing your application), I am unable to see any 
code for the above-mentioned model creation. I cannot understand it.

Could someone out there elaborate on this?

Thank you for your help!

Fix super(new CompoundPropertyModel(this)) error in the WIA book

[David Chang]

Hello, I am learning Wicket by reading <>. I am using Wicket 
1.4.5 and Java 6. 

On page 244, the sample code is as follows:

private int counter = 0;
public MyPage() {
  super(new CompoundPropertyModel(this));
  final Label counterLabel = new Label("counter");
  add(counterLabel);
  counterLabel.setOutputMarkupId(true);
  add(new AjaxLink("counterLabelLink")
@Override
public void onClick(AjaxRequestTarget target) {
counter++;
target.addComponent(counterLabel);
}
});
}

The line has super(new CompoundPropertyModel(this)); gives a compiler error. I 
replaced it with the following:

super();
setDefaultModel(new CompoundPropertyModel(this));

and it works. 

My question is: 

1. Am I doing the right thing?
2. Any better or more elegant way?
3. How much of WIA remains true as far as Wicket 1.4.5 concerned?

Thanks!

Re: Fix super(new CompoundPropertyModel(this)) error in the WIA book

[David Chang]

Martijn,

It is so nice of you to reply to my questions. One question I have about your 
book:

The bottom of Page xxi says: .. from Terracotta for giving Wicket a vaiable 
scaling strategy.

What do you exactly mean by that? Do you mean Terracotta makes the stateful 
programming model less of a concern in terms of memory consumption?

Regards,
David

Questions about how wicket serialization works

[David Chang]

I am reading the book Wicket in Action. Page 88 about serializing models says: 

"At the end of the request, after the markup has been sent to the browser, 
Wicket stores the page, component hierarchy, and associated models (the state) 
in the page store."

Does "Wicket stores the page" means Wicket stores all the page content (markup 
plus Wicket-inserted content) sent to the the browser? 

I did an experiement in which there are two clock pages with dynamtic models 
(same java class and markup, but differnet class/file names). Clicking on a 
link goes to the second clock page. When I click IE Back button to go back to 
the first clock page, it always shows the current date/time. How so? Why not 
showing the previous date/time when the first clock page was loaded?

My understanding is that when a page is refreshed, each Wicket componet on a 
page calls its getObject to update content. Does the Back button get the 
getObject method called too?

What did I miss?

Thanks, David

Re: Questions about how wicket serialization works

[David Chang]

Erik,

Thanks so much for reply to my questions.

>>No, only the serialized form of the page hierarchy is stored.

What do you exactly mean? WiA mentions three things:

Wicket stores 
1. the page, 
2. component hierarchy, 
3. and associated models (the state) in the page store."

By "only the serialized form of the page hierarchy is stored.", you mean the 
first two things?

Regards,
David

Better way to find a parent compoent in page hiearchy?

[David Chang]

I have two pages. The first page is extended by the second page. On the second 
page, I want to access a component on the first page. One way to do this is to 
make the component a member variable of the first page. I feel this way may 
have two drawbacks:

1. A member variable uses more resources (memory, clustring, etc.)
2. Not all pages extending the first page may need to access this component, 
which make it seem unnecessary for such pages.

Is there any more elegant way?

I just started Wicket programming for a personal project. Thanks for any input!

Regards, David

Re: Better way to find a parent compoent in page hiearchy?

[David Chang]

igor, thanks for prompt help! 

I can use Component#findParent(SomeClass.class) to find the first page. How can 
I further find the component by this Wicket ID? I need to overwrite its display 
value.

Thanks again.

Make Wicket component ID HTML element ID?

I have many Wicket components that are unique on pages. I would like to make 
their wicket ID HTML element ID instead of typing HTML id attribute. How can I

Thanks for the info. But this method is only component-level. How can I make 
all Wicket components do this without repeating setOutputMarkupId(true) for 
each component?

Re: Better way to find a parent compoent in page hiearchy?

[David Chang]

Thanks for your input. This is interesting. Somehow I got confused. 

Shouldn't this method be natural part of a Component? As you know, each 
component has child components, which is why a Wicket page has a hiearchy of 
components. 

Let's take MarkcupContainer for the moment. Using this class means I have to 
add another element in the markup page, which seems complicate thhings a bit 
and does not seem elegant.

Did I miss something?

Regards.

Major, thanks for the info. You are right. I did not look down further along

Re: Make Wicket component ID HTML element ID?

[David Chang]

Thanks for the tip. I added this approach to the top page. Here is my 
implemenetation:

visitChildren(new IVisitor() {
@Override
public Object component(Component c) {
c.setOutputMarkupId(true);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});

Is this the right way to implement?

I notice one thing that is not what I want: instead of generating wanted HTML 
element ID such as "signInOut" or "feedback", Wicket added one number or letter 
to wicket ID as HTML element ID (for example: signInOut4, feedbackb).

How can I overcome this?

Regards.

Re: SV: Make Wicket component ID HTML element ID?

[David Chang]

You are right. I need to be cautoius on this. I am new in Wicket. Just for the 
sake of discussion. I put the following code in the top page's constructor:

visitChildren(new IVisitor() {
@Override
public Object component(Component c) {
c.setMarkupId(c.getId());
c.setOutputMarkupId(true);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});

I notice that sub-page Wicket componets did not get their ID outputed as HTML 
element ID. I am confused. Aren't sub-page components are children of the top 
page?

Thanks!

Thanks for this new tip and it shows another approach, which makes me  feel the

How to strip Wicket tags in development mode?

[David Chang]

I understand that in deployment, all Wicket tags are stripped from the rendered 
markup that is sent to the client. 

How can I strip all Wicket tags from the rendered markup in development mode. I 
want to see clean HTML content in the client.

Thanks for help!

Dynamically change feedback panel border color?

[David Chang]

I am using a div with border color to enclose feedback messages. I can control 
whether to generate the feedback div based on whether there is any message to 
render. Now I hope to change its border color depending on the severity of the 
message. But (1) always causes error:

Cannot modify component hierarchy after render phase has started (page version 
cant change then anymore).

How can I change the border color when there is message to render? What is the 
best way?

Thanks!

HTML:



Java code:

add(new FeedbackPanel("feedbackHolder") {
@Override
 public boolean isVisible() {
(1)  if (anyErrorMessage()) 
   add(new SimpleAttributeModifier("class", "redBox"));
  return anyMessage();
 }
});

For FeedbackPanel, I am not sure how to do this. I tried onComponentTag(), etc. 
and it seems there is always compile error. Looks like FeedbackPanel is a 
special beast.

Example of configuring JCaptcha within Wicket?

Where to put an application's configuration parameters?

[David Chang]

Hi, I am new in Wicket. 

I did Spring web applications before and I usually put an app's configuration 
parameters in the application context file. 

I would like to know the best practice in Wichet for setting parameters such as 
SMTP server, LDAP server, etc. Where should I put them? I dont feel 
WebApplication is a good place. Put them in an old java properties file? I want 
these parameters can be changed without touching source code.

Thanks!

Re: Example of configuring JCaptcha within Wicket?

Eelco, 

Thanks for reply. I already read this book and already got the code working by 
understanding the sample code int the book. But I don't like what the default 
image and font look like and hope to change it. 

So I would like to see if there is existing work by folks here so that I dont 
have to re-invent wheels.

Best, David

Wicket allow multiple Spring context files?

[David Chang]

When I did my Spring web applications, I split Spring context files into a few 
smaller ones (example: one for web beans, one for DAO beans, one for Service 
beans, etc). 

I would like to follow the same approach in my Wicket application, but I notice 
a few odd things:

1. The order of these Context files in web.xml plays a role. If not right, 
Tomcat will not start and report wicket "WebApplication" cannot be found.

2. Service beans specified through the following:

@SpringBean
private SupportService supportService;

result in runtime error that the bean of type SuppportService cannot be found 
if a service bean is specified in a different context file other than that of 
wicket "WebApplication".

Any of you had similar experience. Any fix?

Regards.

A question about using Spring in Wicket 1.4

[David Chang]

Yesterday I was looking at the page "Migrating to Wicket 1.4"

http://cwiki.apache.org/WICKET/migrating-to-wicket-14.html

Regarding SpringWebApplication, it says: 

SpringWebApplication has been deprecated in favor of SpringBean annotation. See 
SpringWebApplication javadoc for how to setup SpringBean based injection.

I went to Wicket API about SpringWebApplication and it says:

Deprecated. when using java5 it is preferrable to use SpringBean annotations 
for injection rather then this spring-specific application subclass with its 
helpers. To setup SpringBean add the following line to your WebApplication 
subclass init method add(new SpringComponentInjector(this)); 

Here is my way of using Spring in my wicket app.

1. In the init method:

addComponentInstantiationListener(new SpringComponentInjector(this));

Please note that it is not: add(new SpringComponentInjector(this)); 

2. In wicket components that access Spring beans:

@SpringBean
private SupportService supportService;


Am I doing Spring in Wicket right way?

Thanks for input!

Re: A question about using Spring in Wicket 1.4

[David Chang]

James, thanks for quick reply. I guess I am a little confused is that in the 
init method, I use

addComponentInstantiationListener(new SpringComponentInjector(this));

instead of 

add(new SpringComponentInjector(this));

as "Migrating" guide specified. The Guide-specified approach actually generates 
compiler error.

How to dynamtically generate an image via an Ajax link?

[David Chang]

Hello, I am playing with JCaptcha. My JCaptcha is working (thanks to WIA book). 
I also have an Ajax link for a visitor to change the displayed image if he 
wishes. 

I am new in Wicket and I am trying to follow the idea of defining a model for a 
Wicket image component. However, based on my undersstanding of WIA's 
implementation of JCaptcha, no model is explicitly set and the book code simply 
sets ImageResource.

Does anyone out there know how to dynamically updage an image via Ajax link?

Any pointer or info is really appreciated.

Regards.

Design of Locale-aware dropdown list?

[David Chang]

This question may be beyond Wicket’s scope but I would like to ask folks here. 
I am impressed by their creativity, capability, and passion.

I need to display a dropdown list which is in English or Korean. The options of 
the dropdown list MUST be stored in database. It switches between English and 
Korean depending on the locale in the session. 

How can this requirement be addressed elegantly in all three tiers: web 
(wicket), service, and database, plus the domain objects?

Any input or pointer is really appreciated.

All the best.


P.S. I played with the Locale selection example in the WIA book. It seems the 
options values in different languages are stored text files. Correct?

Recommend two good complete clean Wicket+Spring+Hibernate apps?

[David Chang]

Can anybody recommend to me two good complete clean sample or open source 
Wicket + Spring + Hibernate applications?

One of the effective ways I learn is by learning from good examples.

I would be very much grateful for any info. Hopefully, the sample or open 
source applications are not too big, but still show many points.

Thanks a lot!

Re: Recommend two good complete clean Wicket+Spring+Hibernate apps?

[David Chang]

James, 

I just downloaded your application. Do you have any documentation/presentation 
about this application? 

Do you happen to have knowledge of another good sample/demo app?

Thanks, 
David

Replace "Choose one" from DropDownChoice?

[David Chang]

Hello, I understand that there must be a solution for this. I googled for some 
time and found one or two results that seem to match what I am looking but they 
did not answer my question. Tried myself, not successful. So I want to ask 
folks here. I have a form and it has a dropdown list. Here are my requirements:

1. Replace "Choose one" with a blank line

2. This blank line is the first option and it is always listed no matter 
whether a value is selected or not, no matter whether the form field of this 
dropdown list is required or not.

3. I am using ChoiceRenderer to convert between selection and objects.

4. This behavior is applicable to all DropDownChoice. 

How can meet these requirement?

Thanks for your help!

Regards.

RE: Replace "Choose one" from DropDownChoice?

[David Chang]

Martin,

Thanks so much for chiming in. I tried the 

null=

approach. The blank line in the dropdown list simply disappears. As I said in 
my requirements, I hope to have it there no matter whether a value is selected 
or not, no matter whether it is a required field or not.

Again, thanks for help!
Best,
David

Re: Replace "Choose one" from DropDownChoice?

[David Chang]

Martin, 

According to what you said, do I need to add special processing in 
ChoiceRenderer if this blank line is the selected and I need to convert 
selected value to object?

Thanks,
David
