Re: [Wicket-user] Best practice and use of detachable models
no, not exactly. if you havent set a model on the component (or set it to
null) and call getmodel() wicket will search upwards for a model that
implements the compound model interface. look up compound property models on
that wiki page.
Thanks, will do.
One last question:

write a simple model
private static class foomodel extends abstractreadonlymodel {
private final imodel wrapped;
public foomodel(imodel wrapped) { this.wrapped=wrapped; }
public object getobject() { return wrapped.getobject()+"bar"; }
public void detach() { wrapped.detach(); // important }
}
you do this a lot, so it is very helpful to create a superclass of the
above that helps with setting and detaching. i leave that as an excercise to
you.
Can I assume that doing all this may not be worth it if you are only trying
to derive a simple String value to put into a label - so the "hardcoding"
may be okay for most scenarios?

Ok I get it. Also, when you do "getModel()" Wicket will search upwards the
component hierarchy right? So it does not matter even if you are on a child
panel within the page or something, yes?
e) While rendering each row of the ListView, how do I initialize Labels so

just what you did above - new PropertyModel(item.,getModel(), "name");
or if you use PropertyListView just add(new Label("name")) :)
Yep. Honestly was not aware of PropertyListView and will look into that as
well.

Hi,
I use Hibernate and have got a reasonably sized app working with Wicket.
I am aware of the concept of detachable models and want to use it
effectively and I have the following questions. If the information is
already there on the wiki or something - feel free to point me there.
Apologies in advance for the dumb questions, but I'm sure there is a general
consensus that Wicket models are tricky to understand.
what can be tricky about interface IModel { T getObject(); void
setObject(T t); } ? :)
there is a great wiki page on models that explains all this stuff in detail.
a) If you don't use detachable models, it is ok but the downside is that
when your page is serialized, your models get serialized and this could take
up a lot of memory. Is my understanding correct?
yes. generally you want to keep your session as small as possible. generally
there are no reasons to stick things in there that can be loaded from the
db.
b) In some cases I use new Label("foo", new PropertyModel(fooModel,
"foo"))); and in some cases I use new Label("foo", fooModel.getFoo());
which should I stick to or when should I use which?
if you dont mind the object put in session then you can do foomodel.getfoo()
(like if its something simple like a string)
c) I have a list of objects I got from Hibernate. Can you provide (or link
to) some simple code that will show me how to "install" this model on the
parent component, and I mean in detachable mode. In my case it is just a
WebPage.
add(new listview("list", new loadabledetachablemodel() {
public object load() { return
getsession().createcriteria(user.class).list();
}
}
thats all there is to it. consider this:
public class entitymodel extends loadabledetachablemodel {
private final Class clazz;
private final Serializable id;
public entitymodel(Class clazz, Serializable id) {
this.clazz=clazz; this.id=id;
}
public object load() { return getsession().get(clazz, id); }
}
the above model is a generalized hibernate entity model. you can do thigs
like
setresponsepage(new ViewUserPage(new entitymodel(user.class, 15)));
this model will load the user when getobject() is called, and keep it in
memory during the request. once the request is done and before the page is
saved this model will null the variable that keeps the user so it is not put
in session. only the two key pieces of information necessary to retrieve
this user (and which are hopefully much smaller then the actual user object)
are kept in session.
d) Now I am iterating using ListView. How exactly do I initialize the
ListView so that it uses the "installed" detachable model?
what do you mean? you just pass it into the constructor.
e) While rendering each row of the ListView, how do I initialize Labels so
that they in turn get the right chunk of the detachable model?
just what you did above - new PropertyModel(item.,getModel(), "name");

[Wicket-user] Wicket dev job in the LA Area
Hopefully a job listing isn't out-of-place on wicket-user (if so, I appologize). We are looking for two great wicket developers at FIM Labs, a newly-formed new product research and development group at Fox Interactive Media. We're building a high-profile site witin MySpace using Wicket, and have a bunch of other interesting projects going on. We're a small group that maintains a startup culture while still having access to the resources of Fox (MySpace, FoxSports.com, IGN, AmericanIdol.com, etc). Or focus is on new social web applications. Right now, our group has one Software Engineer and one Sr. Software Engineer position open. We're in the LA area, but we'd be willing to relocate the right person. While we normally go though HR, feel free to send resumes for this position to me (Daniel dot Gould at fox com) and I will forward them along to HR. The job listing is below; that said, we care far more about smart people who can pick things up than any laundry list of tools and languages. (The HR folks normally attach all the info about benefits, free movies on the Fox lot, lunch at our building, stuff about being an equal oppt'y employer, and all that to the bottom of these, but I wanted to send this out to the wicket community right away, so if you need the even more official version, let me know.) -- Daniel Gould VP, Technology Fox Interactive Media 407 N Maple Dr Beverly Hills, CA 90210 Fox Interactive Media (FIM), a start-up division of News Corporation, is seeking a Software Engineer to work on a dynamic and innovative projects. The Newroo team is a part of FIM Labs, which creates new ideas and products used across FIM; we are currently building an exciting system that will be integrated into MySpace and other sites. This project brings together the many of the new and interesting technologies that form what is today, Web 2.0. We are a small, focused, internally driven team--we'd expect the same out of any prospective candidate.

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!
In production mode, the toolbars disapers after refreshing the page a number of times. This means that there are no column headers and no paging lnks. The difference compared to development mode is that in development mode a check for unrendred components is performed, so there I get the exception from the first post.

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!
Yes I can. I simply downloaded the Wicket examples application http://sourceforge.net/project/showfiles.php?group_id=119783&package_id=138752 http://sourceforge.net/project/showfiles.php?group_id=119783&package_id=138752 and deployed the wicket-examples-1.2.5.war, which is in develpment mode, and the exception in below in first post. I am however *not* able to reproduce it with Sun jvm and/or when a debugger is attached! I am running it in a clean/new/default WL 8.1 SP5 installation where Jrockit is selected as JVM.

[Wicket-user] Could this be a bug in Wicket 2?
I've posted this as a reply to another thread but I think it deserves a
thread of its own.
What happens is that I'd like to show and hide a label by setting switch
between setVisible(true) and setVisible(false) when clicking on a
AjaxFallbackLink. I've wrapped the label inside a WebMarkupContainer to make
this doable. Here is the code:
public BasePage() {
final WebMarkupContainer table = new WebMarkupContainer(this,
"tableId");
table.setOutputMarkupId(true);
final Label label = new Label(table, "labelId", "This is a label");
label.setOutputMarkupId(true);
label.setVisible(false);
new AjaxFallbackLink(this, "linkId") {
private static final long serialVersionUID =
5523627214368899839L;
@Override
public void onClick(AjaxRequestTarget target) {
final boolean visible = label.isVisible();
label.setVisible(!visible);
target.addComponent(table);
}
};
}
When I click on the AjaxFallbackLink the first time everything is fine, the
label (with wicket id "labelId") gets visible. But when I click the link
again to make it invisible, I get a NullPointerException when executing
label.setVisible(..). Debugging down into the wicket source code tells me
that the NullPointerException occurs on 327 in class Page, when it tries to
execute "versionManager.componentStateChanging(change)". However
versionManager is null. Why is this? Is this a bug or am I doing something
wrong?
Thanks

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!
Yes, it can be reproduced by the "wicket examples" application from www.wicket-library.com. Of cause we run our application in production mode, but the wicket-examples application is in development mode when downloaded, so it makes no effect on the error other than in development mode the below exception is shown instead of the toolbars just disapering.

Re: [Wicket-user] Dumb question about serialization
If you don't need back button support at all, just have all your pages (or probably some base page) override isVersioned (or use setVersioned) and let it return false. Wicket will not record changes then, and your URLs between what otherwise would have been versions keep stable. Also, set IPageSettings#setMaxPageVersions to 1 and it is best to use the HttpSessionStore.

Sorry about that, that was a slip. We recently had a change that would
allow you to pin the session's locale in the constructor. Setting the

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!
Do you think you can isolate the case and have it reproducible in a test case or quickstart project? I'm also wondering why you run the application in development mode. It doesn't run those render checks when you're in production mode.

This pattern works good for when you have dialogue style pages (gather some info and then return) that could be accessed from a number of different pages (so where to navigate back to is something you want to keep flexible). But the price for the ease is that you'll keep a reference to the page to get back to thus preventing it to be garbage collected. Eelco - Take Surveys. Earn Cash.

[Wicket-user] Strage Weblogic problem with DataTable - help needed!
Hi We were ready to put a new wicket application into production, but after deploying it it on our pre-production server with Weblogic 8.1 SP5+JRockit, we see a really strange and serious problem. Initially after deployment, everything works fine, but after refreshing a page with a DataTable 10-50 times, the toolbar components added to the DataTable (column headers and the paging) disapears! And they disapear on ALL pages using the DataTable component. No errors in any logs, and otherwise everything works perfect. Only re-deploying or restaring the server will make the toolbars come back. Then we tried to download and deploy the Wicket-examples-1.2.5.war, and it also fails in the same way, after refreshing the "DataTable Example" a number of times. Since it is configured as development mode, it does show an exception instead of the toolbars jst disapering. The exception is below, and indicate that the markup has "lost" it references to the toolbars. We can recreate the problem running WL+JRockit locally from IntelliJ, but not when a debugger is attached (probably because optimization is then turned off). The strange thing is that only the toolbar components fail, and that it fails only after showing such a page a number of times. Also when one page with a DataTable has failed, all the pages in the application using DataTable component will be in error Since we are otherwise ready to go into poduction, we really need a workaround or a fix, but changing the application server or JVM will be really difficult because we are a big company with standardized production servers.

[Wicket-user] Dumb question about serialization
Sorry for the dumb question, but I don't see any overview documentation talking about models and serialization in the API. Is there any way to not have to serialize objects in a model? I don't need support for back button / undo / etc. I have some objects that cannot be serialized which need to be displayed in a ListView, and when I try to modify the contents of the ListView, it causes exceptions because it automatically tries to serialize everything which I call modelChanging(). Is there a setting I can change somewhere to run everything in memory? --Jesse Barnum, President, 360Works http://www.360works.com (770) 234-9293 - Take Surveys. Earn Cash.

[Wicket-user] wicket 2.0: setting default locale
hi all,
any ideas how to set a default locale for sessions (wicket 2.0
snapshot)? i support only a limited amount of locales in my app and need
to get some localized data from my database using the sessions locale.
my first thought was to set the locale in my websession's constructor.
but it gets overwritten in WebApplication.getSession again
if (session == null)
{
// Create session using session factory
session = setSessionFactory().newSession(request);
// Set the client Locale for this session
session.setLocale(request.getLocale());
}
as in the Session class constructor the locale is set anyways, is there
a special reason to set the locale again right after the creation?
protected Session(final Application application, Request request)
{
this.locale = request.getLocale();
if (locale == null)
{
throw new IllegalArgumentException("Parameter 'locale' must not
be null");
}
}
thanks for your help!
h.

Re: [Wicket-user] Session is valid?
use for a login or landing page stateless links and forms. (only possible in 1.3/2.0) what do you mean with session is still valid? if you are in a request the session will always be valid or maybe if you have a really long request the session could be invalidated by the container beneath your feet.. but i dont think there is a method on the HttpSession like isValid() The wicket session sessionInvalidated is only set by you if you call invalidate() johan On 2/21/07, Robert . <[EMAIL PROTECTED]> wrote: Hi, Is there a way to see if a session is still valid.

Re: [Wicket-user] Navigation between pages
You can also employ an easy way to go back to the previous page by passing the
current page to the next page. It's been pretty useful for us. Or even telling
the page which page to goto next.
Small pseudo snipplet:
public class mypage extends WebPage {
public mypage(final Page Previous, final Page next, Model model) {
on next button: setresponse(next);
on previous: setresponse(previous);
}

You probably could get by using simple variable substitution like is supported. If you need to do more complex stuff - working with conditionals and loops etc - you could let it be processed by e.g. Velocity in the same fashion variable substitution is done now. But to me it seems unlikely you ever really would need that. > Im thinking that I could store the custom > CSS In either a database or some xml structure, would that be okay because > im having some trouble seeing how I can apply the sharedressource decorator > to the template I don't know... why from a database or xml file when you can just have the raw (non-interpolated) css file with your sources, served as a package resource, and then interpolate with the variables that are specific for the user (and e.g. come from a database)?

Re: [Wicket-user] java.util.ConcurrentModificationException
that looks the problem.
you are adding resource loaders in a page constructor??
why?
You should do that in the Application.init()

Is in the keyboard panel.
Custom resource loader is added in prototype page constructor:
public TemplatePage() {
ClassStringResourceLoader loader = new
ClassStringResourceLoader(this.getApplication(), this.getClass());
this.dbAction = new DBAction(
loader.loadStringResource(this.getClass(),"envContextName",null,null)
