Re: Java Wickets Delete and Checkbox

[Jeremy Thomerson]

Ashu, the most likely cause of your problem is that the ListView is not
implemented correctly. Likely, rather than passing the ListView an
IModel you are passing it just a List when it is created.
This leads to the ListView having stale data. Then you think you need to
"refresh" the ListView. In most cases when it is correctly implemented, the
ListView will "just work" because it will reload its model, getting the
up-to-date list after you've modified the underlying data store (e.g.
deleted things from the database).

The best way for you to get more assistance is to post a code snippet with
your next email that shows how you're creating the listview, the
checkboxes, and the delete.

Re: # in URL

[Jeremy Thomerson]

Browsers don't send the # or anything after it to the server, so you can't
get access to that on the server. You can test this by watching in Firebug
or dev tools in your browser and submitting a request to
http://www.example.com/test/something/#afterhash or anything else. Only the
http://www.example.com/test/something/ part gets sent to the server. Most
JS frameworks use the # and what's after it for client-side state.

 Wicket version: 6.7.0

 I need to get the url parameters even if there is a #, because I have an
 AngularJS app running inside my Wicket page, which requires it. E.g.:
 mysite.com/myapp/#/john. John is shown by Wicket and AngularJS.
 However if there is a # in the url, the PageParemeters object comes in
 null.

 Is there a way to preprocess the url parameters before converting it to a
 PageParemeters object? Or is there another way?

 Thx,
 Carlos.

Re: Wicket and Responsive Design question

[Jeremy Thomerson]

Responsive design means different things to different people. However, the
most common definition these days has to do with markup that adjusts to
various types of devices. Accomplishing this primarily centers around your
HTML, CSS (using media queries, etc), and JS for enhanced features. Thus,
most of that doesn't have a strict requirement for Wicket. If you're new to
responsive design I'd suggest you compare responsive CSS frameworks like
Bootstrap [1] or some alternative [2].

You can use most of these frameworks without any additional Wicket-specific
code by using their flavor of markup and CSS class names, etc. However,
there are integration projects that folks have made available to make
common components that work with these frameworks (like wicket-bootstrap
[3] or [4]) that you can also take advantage of.

There are, of course, finer details to responsive design like providing
alternative image sizes for different devices, etc. However, there are a
myriad of ways those things can be accomplished and what you do largely
depends on your other integrations (i.e. how you serve your static assets,
etc).

Re: Wicket Sessions and Akamai Caching

[Jeremy Thomerson]

Pages that are session-specific should not be cached in a way that allows

session-specific.

Re: Brix CMS has stopped development?

I think that Matej and Igor's company stopped using it, so they had no
reason to develop more on it.  Brian Topping also did some work on it and
tried to lead a second generation of development on it, but I think he too
was pulled in a different direction by $work.

It is a very nice project.  If you are interested in using it and adding
features / updating it, I'm sure that you could be added to the team, or
you could fork it and submit pull requests, etc.

Be careful about the tone of your email.  You may not have meant it this
way, but it sounds a bit snarky and disrespectful.  Sven knows what he's
talking about, and it would be rude if you meant to imply that he doesn't.

To your points:

1) HTML may not allow nested forms, but Wicket does.  It handles this
automatically for you.  Try it some time.
2) Okay, Sven didn't know that because it wasn't mentioned in your first

Solution for your problem:

Use two buttons - one for save, one for search.  Move your onSubmit
logic out of your form and into each button.

Our of curiosity: among the wider community: what security framework(s) do
you use with with Wicket, and why?

[  ] I use my own custom framework
[  ] I use Shiro
[  ] I use Spring Security
[  ] I use WASP/Swarm
[  ] Other (please specify)

And don't forget the why.

Re: Twitter Bootstrap in Wicket

 Is it possible/feasible to 'selectively' use the Twitter bootstrap in a
 wicket app?

 Scenario: our app serves many different clients. Some will want the
 Twitter Bootstrap look and feel but others will be happy to use any
 number of existing CSS/JS templates that we have created for them over
 the years.

 Currently we use a combination of Wicket variations and conditional
 header injection to provide different look and feel for customers even
 though they all use the same Wicket page classes.

 Is it possible to use Twitter Bootstrap in the same way? i.e.
 conditionally use it when rendering a page for one customer but not
 using it when rendering that same page class for another customer?


It sounds like you already have the system for this built.  Bootstrap is
just HTML and CSS, so keep doing what you were with the variations and
different header contributions.  Is there something else that you need?

 *Last cause: The component(s) below failed to render. A common problem is

The error message says it all.  Somewhere you have a component added to
your java hierarchy that is not in the markup.  Look for message in your
codebase.  If you can't find it, put a breakpoint in the Component class
constructor with a conditional if the ID is message.  Find where that
component is being created but not referenced in the markup.

You can also turn this check off, but that's not a fix.  The message is
indicative of a problem.  If you do decide to turn the check off it's
somewhere in the app's settings (debug or markup - can't remember) - look
for component use check.

I'd suggest just using JS for this and doing the highlight on the

the parent TR of the link and then add the appropriate CSS.  There's no
reason to go back to the server just to highlight a row.

If you're just looking for something like data retrieval via normal AJAX
(json/xml/etc as opposed to Wicket's component-replacement AJAX) you can
always use jQuery (or similar) and make calls to a Wicket shared resource
that returns JSON/XML/etc.

Or, in your link override onComponentTagBody and write the text out.  But a

Re: Wicket 6.0.0: RenderStrategy.REDIRECT_TO_RENDER and missing FeedbackMessages in ComponentFeedbackPanel.

If I had to guess I'd guess it's because your KeyValuePair class does not
properly implement either equals or hashCode.  As I say many times during
my classes: don't get so distracted with how do I do this in Wicket that
you forget that this is just java.

It will require JavaScript, so I'd just make it an entirely client-side

 At the MyPage site, the constructor creates a:
 IModelMyModel model = new IModelMyModel() {

 This variable is used to create a CompoundPropertyModel for a Form.

 The first time when I click on my link to the MyPage site, everything

 variable is filled with the selected values from the first time when
 I clicked on the link to the MyPage site.

 I do not understand this behavior. Normally, the MyModel variable

 Has someone an idea?

You'd need to show more code for us to be more helpful.  I'm suspecting
that you are clicking a stateful link on that page, which means of course

 Hi,

 when I apply the Wicket 1.3 way to determine session size,

 Now with Wicket 1.5 using
 Session.get().getSizeInBytes()
 session size is 857bytes. And I can add or remove as many Lables as I
 wish, that size stays the same. Obviously I use it wrong. Currently I
 just add the session size result to a Label added to my single WebPage:
 public HomePage(final PageParameters parameters) {
  ...
  add(new Label(ssize, String.valueOf(Session.get().getSizeInBytes(;

Here you're doing it in the constructor.  So, if this is the first page you
visit there won't be any (Wicket) stuff in the session yet.

Have you tried just adding the debug bar to your page?  Add a dependency to
wicket-devutils in your pom.xml and then add(new DebugBar(someID)); to
your page (and add it to the markup obviously).

Re: Wicket Events

[Jeremy Thomerson]

Have we talked about adding an IEventDispatcher that dispatches events by
their class type based on event method signature?

Example:

class MyComponent {

@EventListener // or some annotation
public void onUserAddedEvent(UserAddedEvent event) {
  // do something here
}

}

Then when someone calls sink(new UserAddedEvent()) it gets dispatched to
only those methods that take a UserAddedEvent as their method argument?

Would that be useful (it seems like it to me - it avoids the instanceof
checks)?  Am I off track?  Is there something like this or better already
built?

An alternative would be that the annotation could take an argument of event
class(es) that it want's to be notified of.

 All components are still detached, but if you override IModel#detach() in

 This has the behavior you describe, since (1) the entity does not need to

 transient (2) it goes away as soon as another page is accessed, and (3) it
 does not get replicated among the cluster.



Well, you admitted you should be reprimanded :)  Doesn't that hack

definitely would not recommend that hack to someone new who is just trying

 Yes. I know that I can redirect all requests but the question is how to

 Parallels Panel and you have to upload your WAR file and the files are

 That's why my application is available under
 www.domain.com/warfilename/home
 My context.xml file in the application has path= so it should start on
 default path


It's a GoDaddy hosting-related question, not Wicket.  Maybe someone here
has done it before, but as someone upthread mentioned you'll really just
have to search GoDaddy tech docs or contact their support for further help.

Re: Wicket 1.5: sessions

[Jeremy Thomerson]

Put a breakpoint in the WebSession constructor and see where it's getting
called.

Or, perhaps you won't see anything there if this is happening because you
are in a serialized WebSession.  You can test that by clearing all cookies,
etc, and starting a new session.

Did you actually read the entire javadoc?  The setStyle javadocs give you a
link to the Session (class) javadocs.  These docs explain what style is and
then give a long list of exactly how all the resources are loaded -
including the style parameter and how it effects resource names.  If you

 Hello again,
 I have the following problem. I have a customized DateTimePanel component,

 pressing submit the date is not valid anymore due to date format.
 For example I have set the locale de-DE, date looks 02.02.2012 I press
 submit, lets say the validation fails for other reason, when I change the
 locale to en-GB the date is still the german format. I have to choose again
 the date, and now it has the right format. If I don't press submit, when
 changing back to de-DE the date has the german format(even if before was
 english format). If I press the submit when locale is en-GB and the I
 change
 to de-DE the date has english format.
 I hope it is clear the situation, and maybe you have an answer for this.
 Thanks.


Please provide code so we can see your custom component and offer
assistance.  It seems like your component should pull the locale from the
session - perhaps in onBeforeRender - rather than requiring that it be set
on the component at construction.

Re: Communication (in-vm) between webapps

[Jeremy Thomerson]

I agree a messaging queue is a nice scalable system.  But I also think
pragmatic approaches are best.  You don't have messages that need to be
sent right now (data sent between disparate apps).  You have a single
command that needs to be invoked.  That happens to be what HTTP is *really*
good at.  And, you're already writing a web app.  That said, I'd choose
Serban's recommendation.  Create a Wicket bookmarkable page that takes a
pre-shared key or some other method of authentication and call that from
the app.  If it's just an encrypted URL param that gives authorization you
don't even need to call it from the other app - just give the user a link
to click that goes straight to the flush cache page on the frontend.
 Open that in a new window, have your page print out all your strings are
belong to us and you're done :)

 It may be overkill at first glance. Only at first glance,

 If you want something scalable and secure, go for a messaging bus:
 For example, why not using  JBoss HornetQ messaging system ?
 It's scalable, multi-protocol, embeddable.

 Your components will be loosely-coupled, scalable and secure, and your
 unit tests  much easier.
 Especially if you deploy your web app to a cluster

 The only thing I need to take care of then is access control, normal

 since the call made from the admin to the frontend will not go over a

 Maybe your web server runs with a user which has no permissions to
 become different user (via sudo).
 When you run it as a normal Java program you run it with your user
 which has this permission.

 In any case it has nothing to do with Wicket.


And if your webapp *is* running as a user with sudo access you're just
asking for trouble.

 The site had some web pages that were stateful and had a sort bar. That
 was removed. Wicket parms in the url are encoded.

 So, a previous link might look like:

 www.site.com/something.html?page=2z=afhyewifewicfhewichewicvhweripcvh

 These pages were indexed by the search engines. Now that the sort
 functions are gone, and, we've made the page a stateless page, requests to
 pages with the wicket parms (in the z=) now return an error as so:

 on stateless page

 Wel, is true of course since that's been removed. However, we want pages
 to still work, just, ignore the wicket stuff.

 Can this be handled via some method in wicket? i.e., something that can
 tell wicket to ignore the wicket stuff for the specific page in question?
 Some stuff in the query string are still used on those pages, just want to
 not process the wicket stateful stuff. Or, is it best handled with
 mod_rewrite in Httpd?


I'm sure it can be handled in Wicket, but even then I'd default to
mod_rewrite for something as simple as always remove parameter X from
query string for pages A, B, C.  To me dealing with old URLs is better
done at that level rather than cluttering the application with it.

You can override newRequestCycle in your application, provide a custom

 I want to know if it's possible to do what i'm trying at the component.html
 , i mean, declaring all types of containers i have (but only 1 will be
 built, at the getType().buildContainer()), and by declaring the wicket:id
 of
 them, it will get the wicket:id from the fields declared at the container
 too.

 It's kinda confuse to explain, i hope someone understand.
 Sorry for bad english.

 Thanks.

This is an XY problem [1].  You're asking can I do this weird thing with a
panel.  Hard to say.  Why don't you explain to us what you're really
trying to accomplish.  My bet is that there is a much better way of doing
it than what you're asking about above.  That's the nature of XY problems.

Re: AW: Dynamically choosing component to add

 Hi Bertrand,

 I have almost the same problem you do (i think, im still a newbie).
 I'm trying to create a component that creates one specific container,
 depending on it's type. So i'd like to add only this container. I'm having
 problem at the .html, since i don't know if i should declare all
 wicket:id=idContainer or just the chosen one, since each container have
 it's own .html, how to 'link' the component html to the container .html.

 I want to know what you did on your .html, 'cause since your adding only
 the
 chosen panel to add, how you declared all possible panels on the .html? i
 wonder if you declared all panels on the .html or only the chosen one...


I think I just responded to you in your own thread - where I didn't know
what you were trying to do.  I still don't claim to fully understand, but I
think I better understand your question here.  If you mean that you have
one panel that *may possibly contain any one of X panels*, then here's one
solution:

ContainingPanel.html:

wicket:panel
  Some markup here
  Blah, blah, blah...
  div wicket:id=childPanel/div
  More surrounding markup...
/wicket:panel

ContainingPanel.java:

class ContainingPanel extends Panel {

  public void onBeforeRender() {
if(getModelObject() is of some type) {
  addOrReplace(new SomePanel(childPanel));
} else if(getModelObject() is of some other type) {
  addOrReplace(new SomeOtherPanel(childPanel));
}
  }
}

You only need one wicket:id in your containing panel.  You just swap at
runtime which component actually shows up in that spot.

Re: Added issue for assertFeedback

 I've just submitted issue WICKET-4246 for the problem I found where
 WicketTester.assertFeedback required the actual feedback messages to be the

 unspecified and nondeterministic order, testing for the existence of

 I'd provide a patch, but I'm not sure what is more Wicket-y; have
 assertFeedback compare a sorted version of the expected messages to a
 sorted version of the actual messages, or to add a
 WicketTester.assertFeedbackInAnyOrder method.

 I did later attach a Maven quickstart project. This has a test class with
 two methods, one of which will fail in each run; the one that does cannot

 Dear wicket community,

 In a project that I'm working on, I need to build a live log viewer or

 Much like how hudson/jenkins displays the console output.

 The idea is to dynamically display the new data added to a log file along
 with the existing content.

 How to go about doing this? Please throw some light on this.

 I searched about this in the web, mailing lists but couldn't find what I
 was looking for, so I'm posting it here.
 If this is asked elsewhere, kindly re-direct me to the respective resource.


I suppose you're only asking about the web UI portion of this application.
 The service / backend stuff is out of the context of this forum.
 (Although I would suggest looking at using something like Camel that has
all the necessary stuff for monitoring files and file streams and then
routing messages through to your application and/or other processors - see
[1] below).

For the web UI part, there are basically two methods: push, poll

1 - push - using something like cometd, etc to do AJAX push events (really,
these are long-pollers, leaving long-running HTTP requests going and
processing a stream of events that are received over the life of the
connection)

2 - poll - if you have some component that shows the last X lines of a log
file, just call component.add(new AjaxSelfUpdatingTimer(someDuration)).  As
long as you've written your IModel correctly (it always retrieves the most
up-to-date data), this will work out of the box

[1] http://camel.apache.org/stream.html - and things like scanStream

Re: Apache Wicket is a Flawed Framework

[Jeremy Thomerson]

 the same things - it's not the
silver bullet for every application on the internet.  You'll find a lot of
pragmatic and open-minded developers in this community.  But you can't come
think you're going to teach us all something by telling us how stupid we
are and talking in a demeaning way.


 I am definitely in the “I like to hand-code HTML, CSS, and Javascript”
 camp.


You should love Wicket then.  It gives you absolute control over your HTML.
 You won't get that in JSF (
http://code.google.com/p/maps4jsf/wiki/JSFMarkupPrototypes)


 I even like hand-coding SQL.  I get complete control.  These are all pretty
 easy languages; most of them are declarative.  They are easier than Java.
  I
 know most Java developers do not feel this way and want to just do
 everything in Java.  I think you should use the best tool for the job.
  Java
 is a mediocre tool to use in every domain.


I agree.  I use a fair amount of other languages within various
applications that I write.  I'm even refactoring some image and video
processing that I previously did in Java to be done with a combination of
bash and perl using linux applications, communicating with my Java app
through STOMP (through ActiveMQ).  It's fun stuff.  Much better than
image/video processing in Java, which is a total nightmare for the simple
things I need.

 I am letting Wicket set the markup ids.  Only one user is setup in a

 {
  MyDisplayRow row = new MyDisplayRow();

 Hi Peter,

 I was wondering if you had a chance to go through the estimates. The hybrid
 option (3) comes in at around 4.4 days and gives Logica a system that will
 allow them to demonstrate uploading of payroll files and progress through
 the workflow using the existing functionality while providing no risk
 because we aren’t adding any extra functionality or model changes – purely
 reskinning and mocking up other features. This option’s effort actually
 comes in slightly less than option 1 – adding changes to the existing mock
 up because simulating many of the feedback features in a mock up is not
 trivial and many of them are already present in the current prototype.

 ** **

 Given the 4.4 days effort on the hybrid option I could complete this by
 Saturday our time, Friday their time (by working standard days or quicker if
 I put in some 14 hour days – but probably not necessary) which would allow
 them to get acquainted with it for their demo on 2/11. In fact, given that
 the changes in the hybrid are purely mock up (except for the addition of NI
 number – which is a trivial addition of an extra field) there are no reasons
 why they couldn’t start preparing for their demo earlier as only the look
 and feel will be changing as the hybrid option avoids ‘blow out’ risk by
 avoiding any underlying model changes.

It'd definitely be worth optimizing if we can prove it's a bottle-neck.  But
we try to avoid premature optimization.  Can you put together some numbers

Heh.  You just said we have a very active community.

While I do like Stack Overflow for many things, it's not a true way of
building a community.  It's a way of asking questions.  (Yes, this is just
my opinion - not meaning to start a flamewar).  We have a vibrant community
here - I don't think the mailing list is limiting the community.

Plus, mailing lists are still THE way to communicate in open source.
 Especially is this true with Apache projects.


 Moreover, research on old messages are poorly referenced. I
 have recently experienced it one more time  during the migration of my
 project on Wicket 1.5. The solution to my problem has already been
 discussed
 and resolved but it took me a long time to find it. Why not drop this
 mailing list and discuss all questions
 onStackOverflow. The business community would be more visible.


How can we quantify such a statement?  If you can provide some kind of proof
that it's easier to find an answer by searching SO rather than mailing list
archives, we could look into alternatives.  But such a statement just isn't
easily (if at all) quantifiable.


 Source management and bugs are also outdated. The version on github is much
 better.


Github is awesome.  I don't care about the issue management on it.  JIRA has
a ton more features and support.  It works for us.  I think that we would
like to move to git at some point - but it's not (yet) supported for all
projects at the ASF.  There is a public beta running of git for one project
at the ASF right now.  If it succeeds, I think we'll be one of the first
projects to switch as soon as they make it available to all projects.


 My 2 cents,

 Gaetan

Re: AutoCompleteTextField which uses an Object, not a String

Re: Getting Parameters from URL

[Jeremy Thomerson]

Hielke's response is spot-on.  The real question is: why do you need to
access parameters in your session?  At least your example is concerning -
it's not typically a good sign to be pulling the User ID from the request
(where it looks like you're using it to create a session for a user).

 If you wish to check url parameters for each request I would suggest you
 do this in RequestCycle.onBeginRequest(). There is also
 RequestCylce.onEndRequest() if you need to do anything at the end of the
 cycle (letting go of variables and what not).

 If you want to check parameters only for a few pages then you could also
 choose to use the Page(PageParameters) constructor, wicket will give
 that constructor a hashmap with all the parameters from the url.

 Subject: Getting Parameters from URL

 We have code in our session object as follows:

 public class OurSession extends WebSession {

   public OurSession(Request request)}{
   super(request)
   // GET PARAMETERS FROM REQUEST
   userId = request.getParameter(userId);
  }

 }

 This works the first time, so if the url has a parameter of userId=JOHN
 then this can be picked up in the above code.
 However, if the application is again requested from the browser (and the
 session already exists), this code will not get called.
 What is then the best way to pick up the parameters on the url?
 Thanks

Re: Use of AbstractReadOnlyModel

[Jeremy Thomerson]

On Fri, Apr 15, 2011 at 8:43 PM, Marek Šabo ms...@buk.cvut.cz wrote:

 Hi all,

 I would like to ask for some examples where use of AROM comes in handy. We
 had a sort of dispute in one project whether it is better to provide static
 text, no i18n labels with Model.of(Object o) or

final Object o;
new AbstractReadOnlyModel(){

getObject() {
return o;
};
 }


Functionally, your two models are equivalent.  They both have a private
instance variable that contains the object that will be returned by
getObject.

Could someone who uses them in fitting scenarion provide some advice? It
 shows up in our code more and more often and I'm not convinced of that being
 right. That argument was augmented by ResourceModel being sublclass of AROM.



I see people use AROM all over the place for all the wrong reasons.  Doing
things like the following are typically *bad*:

// this should typically be a LoadableDetachableModel:
new AbstractReadOnlyModelFoo { public Foo getObject() { return
database.getFoo(); } }

// this is almost always from a wrong understanding of what models are:
(in a ListView):
newItem(ListItemFoo item) {
  final Foo obj = item.getModelObject();
  add(new Label(label, new AbstractReadOnlyModelString() {
public String getObject() {
  return obj.getSomeString();
}
  });
  // see guys!  I'm awesome!  I used a MODEL
}

AbstractReadOnly models are good to use when your use meets all the
following criteria:
1 - you're using it for a read-only component (label, etc)
2 - whatever you must store in it is okay to be serialized (remember that if
your getObject method references a final variable declared outside of the
AROM, that entire object will be serialized into your AROM as a private
field by the compiler)
3 - whatever you are returning is cheap to retrieve (if it's not, like you
must get it from the database, you will typically want a
LoadableDetachableModel)

Acceptable use:
add(new Label(username, new AbstractReadOnlyModelString() {
  public String getObject() {
return getSession().getUser().getUsername();
  }
});

In this example:
1 - I'm using it on a label
2 - I'm not stroring any state in my AROM, because I have no fields in the
anonymous class, and I'm not accessing a final variable declared outside the
class
3 - Assuming the user is kept in session memory, I'm not doing a DB lookup
or other expensive operation to get that string in my AROM

Of course, I could have also done this:
add(new Label(username, new PropertyModelString(this,
session.user.username)));

Honestly, I don't use AROM a whole lot.  LDM and PropertyModel are generally
the most common.  But I'm sure Igor will prove me wrong :)

iain.redd...@beatsystems.comwrote:

 Firstly, that LDM code is broken - calling detach() on load() makes no
 sense.


Right - you should *not* call detach from within load().


 Also, it will hit hibernate on every call to getObject(), as you aren't
 caching the loaded Parent entity. This is probably the cause of the
 hibernate exceptions you are seeing.


Wrong - LDM caches the returned object within it.  That's the whole point of
LDM.


 Check out http://wicketinaction.com/2008/09/building-a-smart-entitymodel/for 
 a solid persistence backed LDM implementation.

 Unrelated, your ParentsService.load() method probably doesn't need to take
 the entity class a parameter - the service should know the entity type it is
 querying hibernate for.

Re: fter 1 minute the Pagemap null is still locked by: Thread[[ACTIVE]

[Jeremy Thomerson]

You should use some asynchronous querying.  In other words, you search is
submitted to a background process and the Wicket request completes to some
intermediary please wait while we do your search page (like all the big
airline middlemen do)  It polls the background service to see if it's
complete, and when it is, continues on.

You don't want page requests that literally take minutes.

Re: Set all form fields to output markup id automatically

[Jeremy Thomerson]

On Sun, Mar 27, 2011 at 11:43 PM, Bruno Borges bruno.bor...@gmail.comwrote:

 For now, I simply did this:

  object autoMarkupId extends IComponentInstantiationListener {
 def onInstantiation(component: Component) {
if (component.isInstanceOf[FormComponent[_]]) {
   component.setOutputMarkupId(true)
   component.setMarkupId(component.getId())
}
 }
  }

  getComponentInstantiationListeners().add(autoMarkupId);

 I've been playing with this technic, of having all Form components
 outputing
 their ids as is. Of course, this is application-specific, and Wicket should
 not take this to its core.


I personally would suggest *not* having that second line
component.setMarkupId(component.getId()) there.  Let Wicket generate the
IDs for you so that they're all unique on a page.  Your approach above
breaks using two EmailAddressTextField (fake example class) components on
the same page.

Designers should use css class to style.  An occasional ID that isn't
attached to a Wicket component can also help (div surrounding content
section, etc).

But it seems that improves development time, when the web designer codes CSS
 and HTML with the application running on his machine. No more code like

  wicket:id=foo id=foo

 Now, I'm considering to implement a different way to define a Wicket
 component in the HTML:

   div id=w_foo
   /div

  add(new WebMarkupContainer(foo));

 What you guys think of this?


This approach of coding in the markup and automagic generation of components
has been discussed numerous times.  It's not in line with Wicket's core
principles, so we won't add it, but we've made it easy enough to add it to
your own app.  However, watch out: the example you give above is useless -
it just creates a markup container.  So, the next request will be let me
configure that component by adding attributes in the markup; maybe I can
have 'property='firstName'' to show that this should be a label that
displays the first name.  Now you're programming in markup - you might as
well use PHP!  :P

 For the past nine months I have been quietly working on a book about
 Wicket. Unlike other books on the market this one does not attempt to
 teach you Wicket from the ground up. Instead, it is for developers who
 already know the basics and want to learn how to implement some of the
 more advanced use cases. Essentially, it contains recipes that show
 the reader how to implement solutions to some of, what I think are,
 the most commonly asked questions and stumbling blocks. This morning I
 was informed that the book has been published! You can read more about
 it and pick up a copy on PACKT's Site[1]. I hope you enjoy it, more
 details below...

 [1] https://www.packtpub.com/apache-wicket-cookbook/book

 ## Description ##

 Apache Wicket is one of the most famous Java web application
 frameworks. Wicket simplifies web development and makes it fun. Are
 you bored of going through countless pages of theory to find out how
 to get your web development done? With this book in hand, you don't
 need to go through hundreds of pages to figure out how you will
 actually build a web application. You will get practical solutions to
 your common everyday development tasks to pace up your development
 activities.

 Apache Wicket Cookbook provides you with information that gets your
 problems solved quickly without beating around the bush. This book is
 perfect for you if you are ready to take the next step from tutorials
 and step into the practical world. It will take you beyond the basics
 of using Apache Wicket and show you how to leverage Wicket's advanced
 features to create simpler and more maintainable solutions to what at
 first may seem complex problems.

 You will learn how to integrate with client-side technologies such as
 JavaScript libraries or Flash components, which will help you to build
 your application faster. You will discover how to use Wicket paradigms
 to factor out commonly used code into custom Components, which will
 reduce the maintenance cost of your application, and how to leverage
 the existing Wicket Components to make your own code simpler.

 A straightforward Cookbook with highly focused practical recipes to
 make your web application development easier with the Wicket web
 framework

 ## What you will learn from this book ##

 * Leverage Wicket to implement a wide variety of both simple and
 advanced use cases in a narrative that gets straight to the point
 * Make forms work in the crazy world of the Web by learning the ways
 of Wicket's form processing
 * Simplify localizing your Wicket applications
 * Take the boring out of your forms by discovering how to improve the
 user experience while simplifying your code at the same time
 * Leverage the built-in Table component to make displaying tabular data a
 snap
 * Think Wicket's Borders are not very useful? Learn to use them in
 unexpected places to simplify things
 * See how to integrate with Flash components and create interactive
 charts at the same time
 * Web 1.0 too boring? Learn how to tame Wicket's AJAX support and
 bring your application into Web 2.0
 * Simplify your security code by learning various security techniques
 * An application cannot be built with Wicket alone; see how to make it
 play nice with other frameworks

 ## Approach ##

 This is a hands-on practical guide to a large variety of topics and
 use cases. This book tries to use real-world examples when possible,
 but is not afraid to come up with a contrived pretext if it makes
 explaining the problem simpler. Unlike a lot of other books, this one
 does not try to maintain a continuous theme from chapter to chapter,
 such as demonstrating solutions on the same fictional application;
 doing so would be almost impossible given the wide variety of recipes
 presented here. Instead, this book concentrates on focused problems
 users are likely to encounter and shows clear solutions in a
 step-by-step manner. This book tries to teach by example and is not
 afraid to show a lot of code because, after all, it is for coders.

 ## Who this book is written for ##

 This book is for current users of the Apache Wicket framework; it is
 not an introduction to Wicket that will bore you with tons of theory.
 You are expected to have built or maintained a simple Wicket
 application in the past and to be looking to learn new and better ways
 of using Wicket. If you are ready to take your Wicket skills to the
 next level this book is for you.

 Cheers, and I hope you enjoy the book!

Re: Wicket in Action: problem with redirection

 I'm a Wicket newbie, working my way through /Wicket in Action.

 /I don't understand redirection too clearly yet, but there is
 an example in the book which doesn't work right when I
 try it and I'd like to ask if the book example code makes
 sense to more experienced folks.

 Page 271 Listing 11.3 line 4: The onSubmit() method calls
 !continueToOriginalDestination().


continueToOriginalDestination() lets the user continue on to the place they
were going before being interrupted by the security mechanism if they aren't
logged in.  i.e:

user on home page
user clicks restricted page link
security strategy says can't go there without being logged in as X,
redirects user to login page
user logs in, and continueToOriginalDestination() redirects to restricted
page (original dest) and returns true.

another example:
user clicks bookmarked link in a new tab in their browser to login page (or
goes to unrestricted home page and clicks link for login page)
user logs in, and continueToOriginalDestination() can't redirect them
anywhere, because there is no original destination that was interrupted

Page 272 Listing 11.4 , new Link(...){ ... method onClick():
 throws new RestartResponseAtInterceptPageException(signInPage)


This is a way to stop processing at ANY point in your application and
redirect the user to a certain page.


 How is this supposed to work?

 Suppose the user is on the Home page, and the Home Page
 has a UserPanel, and the user clicks on the Sign In link.
 Then  the link itself sets an intercept to the sign-in page
 (that is how the link arranges to take you there, as far as I can
 understand).

 But then, when the user enters name/password and submits, and
 the submit method  calls continueToOriginalDestination(), it will
 always succceed, and find the original destination to be the signIn
 page, regardless of where it really originated (the Home Page, in
 this case).


You're a bit confused by original and destination.  Since the user
clicked the signin page link, the *destination* was the signin page -
which is unrestricted, so the continueToOriginalDestination() method can not
redirect them anywhere, and thus returns false.  You now need to redirect
them somewhere manually or the signin page will re-render.

The *origin* was the home page - but that doesn't matter.  Don't be thrown
off by original (destination) and origin - which are two different
things.  :)

For a while my code was working like that: Signing in worked,
 i.e. it did sign you in, but you were returned to a blank sign-in page.
 (My code doesn't work like that just this minute, but that is only
 because I've been enhancing it with other bugs.)

 Can anyone explain how the book-example is supposed to work?

 Thanks
 Jim

If this were a sum of something else dynamic on the page, it should be done

 Doing it, for instance, an AbstractReadOnlyModel would ensure that the

Don't share components across pages.  It will cause problems.  Most likely,
it is not your component that actually takes a long time to load - it's
probably the data.  You may be loading it in the constructor, but you
shouldn't be.  You should be loading it in a model
(LoadableDetachableModel).  And, you should load it from a service that does
this caching / refreshing for you.  It shouldn't be managed by your UI.

I could be off - but that answer is right 99% of the time for these
questions.  If I'm off, send more details, preferably including code.

 thanks for the reply , yes it is the model which takes time to load, I did
 not start the coding yet  to show you the code  I am   looking for

 write now my idea is to create this model object when user logs in and put
 in his session, this panel gets the data from session  and  it will have
 AjaxSelfUpdatingTimerBehavior  to  update  itself.
 but the difficult part   where  I need advice is how to tell my session to
 reload this model at frequent intervals?
  if this is not a good idea please advice me  with  better way to do .


I don't think you should be doing this in your UI layer at all.  It'd be
better IMHO as a function of a service that handles caching, uses a least
recently used map, expires caches after X seconds / minutes, optionally
refreshes that cache after X seconds / minutes, etc.  Your UI component
would just get it from this caching / data management service, which should
always be a quick operation after the first retrieval.

Re: Unable to update FeedBackPanel within AjaxEventBehavior call

That error is on the client side, meaning that the markup can't be found.


 my question is how do I find this component programmatically? is there a
 getComponentByID call or something?? I call my compenent feedback, where
 is the 'feedback91' comming from??


You must have already found or referenced your component in your server
side code to add it to the ajax request target.  So, what do you mean by
this question?

feedback91 is the markup ID associated to the component by Wicket.  That's
the markup ID that is not showing up in the client side of the page.

Your problem is most likely related to the feedback panel or one of its
parents being invisible during the initial request, which is why it can't be
found on the page when you do the ajax update.

Try calling feedback.setOutputMarkupPlaceholder(true) where you created the
feedback panel.

Also, I am using AjaxEventBehavior on a checkbox so that once the checkbox
 is clicked, I would like to update the feedback panel without refreshing
 the
 page. How could this be accomplished?? is there some sort of render that
 would show the new message in the feedbackpanel?


It appears that you're already doing what needs to be done (namely, adding
the feedback panel to the ajax request target), but it's not appearing
because of the aforementioned problem.

Re: usage of JavascriptFilteredIntoFooterHeaderResponse

 Hi Jeremy,

 Thanks for the implementation ( I've found that you're the author of most
 of
 the files :) ) - it will be really useful in the future.

 1st problem I ran into - no usage example in Javadocs :) However, mailing
 list helped!
 ... after that
 I've found that one of the core WiQuery classes renders javascript with
 response.renderString method (
 org.wicketstuff.jquery.JQueryBehavior.renderHead(IHeaderResponse) ):


Hmm, yeah, renderString doesn't give us any metadata to work with to realize
it's JS and therefore filter it.  It could be anything, or any combination
of things.  I think you should ask the WiQuery guys to change their usage to
use renderJavascript so that you can use this with it.


@Override
public void renderHead(IHeaderResponse response) {
try {
super.renderHead(response);
if(getIncludeJQueryJS(response)) {
response.renderJavascriptReference(JQUERY_JS);
if
 (Application.DEVELOPMENT.equals(Application.get().getConfigurationType()))
 {
response.renderJavascriptReference(JQUERY_DEBUG_JS);
}
}
CharSequence script = getOnReadyScript();
if ((script != null)  (script.length()  0)) {
StringBuilder builder = new StringBuilder();
builder.append(script
 type=\text/javascript\\n$(document).ready(function(){\n);
builder.append(script);
builder.append(\n});/script);
response.renderString(builder.toString());
}
} catch (RuntimeException exc) {
throw exc;
} catch (Exception exc) {
throw new RuntimeException(wrap:  + exc.getMessage(), exc);
}
}


 Which is not being filtered and gets into header - which causes the
 $('document') string to be not valid before jquery.js was loaded.

 Basic features looks good and definitely a good start!

 Probably I'll need more examples how to use
 AbstractResourceDependentResourceReference to create JS Reference
 dependencies and make sure the order is all right.


Take a look at the examples and start a thread for questions if you have
them.

 I'm sorry that I said that I loaded the list from a database, since that
 has
 apparently created a distraction from my key point, which is that if you
 start with a ListC and pass it to Model.listOf, you get back something
 that is not a ListC, which is undesirable and perhaps unnecessary.


I understood your key point, which is why I said as a side note but my
point still remains.  Loading a list and then sticking it into Model class
is in almost all cases a *bad* idea.


  So use the Model constructors instead.  The factory methods are just
 there
  to help remove some verbosity related to generics.
 

 Have you tried this yourself?  Because it doesn't work.  You can only
 instantiate Model with a Serializable instance, and java.util.List does not
 implement Serializable.  The whole point of the ofList method is to
 generate
 serializable lists, and the documentation even says so: This factory
 method
 will automatically rebuild a nonserializable list into a serializable one.
 You're confusing Model.listOf with Model.of.


Sorry, yes, it was early and I wasn't paying attention.  Hadn't had my
Wheaties yet :)  Have you looked at the ListModel class?  It may help with
what you're looking for.

Do you have a suggestion for a better method signature for that method?  The
problem you are describing, if I understand your description correctly, is a
problem with Java generics, not with Wicket's use of them.

Re: DataTable and toolbar

[Jeremy Thomerson]

WebMarkupContainer requires an ID.  The magic here is happening in the
ToolbarContainer class, which is delegating its rendering to the toolbar
that you passed in.  The requirement of the toolbar component ID appears to
be somewhat arbitrary, probably just to remove confusion about what ID to
use, or else for legacy reasons where it may have appeared in the markup.

 I'm constantly running into problems with this method:

 public static C IModelList? extends C ofList(final List? extends C
 list)

 This says that ofList takes, as a parameter, a List of C or some subclass
 of
 C, and returns a List of C or of some subclass of C.

 The problem that I keep having is that the type of the input list and the
 type of the output list may not be the same.  I think that in practice they
 are, but the compiler does not know that.  If C = StringedInstrument then
 the parameter may be ListViolin while the returned list may be
 ListGuitar.

 So every time I call Model.listOf, the type parameter of my List becomes
 hazy, which has annoying downstream effects.  If I load a
 ListStringedInstrument from a database, then pass it to Model.ofList, I
 wind up with a List? extends StringedInstrument--the compiler has no idea
 what the generic type of the List is, only that whatever it is, it is
 compatible with StringedInstrument.


As a side note, rarely should you ever use Model class for a list of things,
especially things loaded from a database.  If you then pass that model to a
component, all the things in it will be serialized.

You should be using LoadableDetachableModel and have the load from
database logic in the load method.

Model is just a dataholder implementation of IModel that should typically
only be used for transient data (data that can't be loaded from somewhere)
because it must serialize whatever you get it.  This is especially bad
whenever you are dealing with any collection of things.


  I can still get StringedInstrument
 instances out of the List, but I can't pass it to any method (like a
 component constructor) that takes a ListStringedInstrument or an
 IModelListStringedInstrument without ugly casting.

 Since Model.ofList must return a list that is compatible with the original
 list--it's a wrapper, not a transformer--can't it just take ListC and
 return ListC?

 Same goes for the other ofCollection-type methods.


So use the Model constructors instead.  The factory methods are just there
to help remove some verbosity related to generics.
