We had to disable and skip components instead of columns, but the principle might be relevant: We created custom components for all form field types we use (textfield, dropdown, radiochioce, etc.) The component consists of an "editable" and a "read-only" variant of the underlying control, but only one or the other is visible depending on the "enabled" flag of the composite component. (unauthorised users wouldn't be much interested in what they can not set a radiochoice field to for example. Disabled textfields are hard to copy-paste from.) The "visible" flag is obeyed too. (the markup is a bit nasty because of this: the form is a table, and the components are table rows so they can be omitted without visual glitches. Shouldn't be a problem with table rows.) We also added convenience constructors to the components, passing the "enabled" and "visible" flags, matching with convenience service methods on the logged in user meeting authorisation criteria. Here we are implicitly relying on wicket being "safe" in the sense that no client side forgery can result in the activation of a missing or disabled component. (all operations are double-checked in the service layer nonetheless.) We didn't use wicket-auth-roles because the categories were too simple at first (but then project scope drift started...) You'll have to substitute table columns for components, it already has isVisible, and you can just add isEnabled. Hope it helps!

Yes, and that's a (non-)web programming model some of us are considering currently. I would summarise the principle as "RESTful service, stateful GUI", the former being 100% server-side, the later being 100% browser-side. I said non-web model because it uses the browser not as a web browser but as a platform to download and execute the stateful client. Some of that state might be made bookmarkable with some tricks, but that's probably just a way to pass initial parameters to the client, ignored by the (static) server. At the risk of getting increasingly off topic, I'd like to continue this discussion for the off chance of inspiring somebody to extend the wicket AJAX functionality in this direction (of which I have very little understanding currently). I for example been looking to broaden our web GUI development skill portfolio (currently wicket only :-) ) by experimenting with something more "rapid". Sometimes I just don't need an elaborate, server-controlled application, just some JS-heavy HTML kicking around simple web services which already exist or I have to provide anyway. I'm about to plunge into GWT, hoping to replace its built-in server-side components, XML-RPC and serialization mechanism with external JSON-encoded REST services if possible. (Same Origin Policy is one obstacle, authentication is another...) So assuming this works (and it does seem to work similarly in GMail which I right now use to compose this message along with possibly hundreds of thousands of others at the same time), can wicket be extended with this principle? Wicket could work as it does now as fallback and for the parts of the application that fit the wicket model better, but have some of its AJAX callbacks "outsourced" to pure data services. The fallback could call the same or a more direct (trusted or an EJB even) service from the server side. Oh well, just a thought.

I think he meant you should also clear the value from the model of the

stubbornTextField.setModelObject("");
Or if you have a CompundPropertyModel for the form instead of
individual models on the fileds, update that directly.

Re: ajax popup on traditional form
On 3/4/08, Gabor Szokoli <[EMAIL PROTECTED]> wrote: > In the ajax debug window, I can only see the modalwindow form > submission, and no further activity. Woops, this part was wrong. The component was sent in the ajax response, but without the new choices added to the model by the modalwindow from submission. So we looked deeper, and we found the mistake we made: It has nothind to do with ajax. It was passing the model to the ListMultipleChoice: new ListMultipleChoice(wicketId, PropertyModel(parentsCompundPropertyModel, wicketId)) did the trick. With other components, this is equivalent to the wicketId-only constructor. Browsing the sources it seems to me that AbstractChoice breaks this convention: If you supply a model, that's your "choices" model. If you don't, your choices model is the empty list. I understand the reason (the choices model is only the secondary model), just wanted to point out the possible (and now actual) source of misunderstanding.

You are right, adding the specific component to the ajaxtarget prevents the unaffected fileds from being effected, thanks.

ajax popup on traditional form
Hi there, We have a regular form with an ajax modal window as popup helper for populating one of the form fields, looks a bit like a datepicker. Except the helper produces the form data in a non-trivial manner, involving server roundtrip. The field does get populated nicely, but all entries in all other fields on the same form are lost. What behavior should I put on what component to make form fields silently persist their current, unsubmitted values to the server when the modalwindow is opened? Any pointers would be aprechiated. And on top of that, some kind of general "roundtrip-less wicket for the ajax illiterate" guide document would be nice. Something brief enough as a javadoc to the wicket ajax package would suffice. We love wicket because we got by with it fine without substantial html knowledge. Until we stumbled into ajax. Now we suddenly have to catch up on html, javascript, DOM, xmlhttprequest, etc just to figure out what's what. And then in the end the solution never involves any of that, just passing the right thingie hadler as the whotsit to the doohickey.

Do people ever use non trivial getters and setters in their JavaBeans? We don't. Type safety and JPA are nice though, so we use JavaBeans everywhere else :-) But I just can't help wondering how the complexity (and performance) of current reflection/bytecode generation efforts would compare to porting all the JavaBean based tools and utilities to some different datastructure convention? One designed for programmatic manipulation. Like a Map where the key contains the type of the value. Some EnumMap-like optimisation could be employed when the keys are known compile-time.

loosely coupled panels: react to model object change
Hi! We are trying to build our application from loosely coupled panels, sharing models here and there as needed. It works wounderfully 90% of the time: as long as the panels contain wicket components only, and no further UI logic. One panel can update a model, and the data is reflected in the components of the other panel, as it should. But sometimes one panel needs to perform an action when its model object is changed from an onClick handler on another panel. OnModelChanged is not called, because the other panel has no direct reference to this panel to perform a setObject on it, they only share a model, and do setObject on that. Where do I put my OnModelObjectChanged event handling code without sacrificing too much from my lovely loosely coupling? Any advice is warmly welcome.

Instead of embedding localised strings into the java code, you could
try to put them into property files, and use a StringResourceModel to
reference them:
Label lblTest=new Label("lblTest",new StringResourceModel("testKey"));
This is a good strategy to prepare your application for multi-language

"Streaming" a huge ZIP file
Hi there,
The downside of an easy-to-use framework is the influx of users with
little understanding of the underlying servlet technology, like me.
Observe:
I'd like to provide a ZIP file (could be TAR, anything Windows PCs can
save and later extract from) as a download, one that is potentially
too big to be kept in memory in full.
So I guess I'd need to "stream" it in chunks, or as a java stream or channel.
Can I do that from wicket?
Or does the servlet interface require a fully assembled response in memory?
Currently I assemble the ZIP file in a byte array in full, but it
feels awkward. Would extending WebResource fit the bill?
ByteArrayOutputStream bout = new
ByteArrayOutputStream();
ZipOutputStream zout = new ZipOutputStream(bout);
// Add entries
zout.finish();
zout.close();
Resource resource = new
ByteArrayResource("application/zip",
bout.toByteArray());
ResourceStreamRequestTarget target = new
ResourceStreamRequestTarget(resource.getResourceStream());
target.setFileName(new
SimpleDateFormat("MMddHHmmss").format(Calendar.getInstance().getTime())
+ ".zip");
getRequestCycle().setRequestTarget(target);
All suggestions are welcome.

and the embedded model must reference the live user object instead of
copying it, so new PropertyModel(user) would make more sense.
I sure hope I got it right this time :-)

Re: Silly problem with button model

I think the problem is you set the enabled/disabled model value once,
statically, in the constructor, so it forever maintains the value
correct at that time.
The simplest way to work around this is to set the model object every
time from the buttons @Override onSubmit() method.
Now a nicer (but more advanced) way would be to keep your strings for
the button captions in (localised) property files in the form of
toggle.true=Disable
toggle.false=Disable
and then the buttons model can be something like this:
IModel action = new StringResourceModel("toggle.${account.enabled}",
this, new Model(user));
Not 100% sure, I'm just making it up :-)

PageParameter backed models?
Hi there, I'd like to have a search form, which keeps the last submitted search parameters in PageParameters in a bookmarkable fashion. I am wondering about the "wicket way" of doing this, and I keep coming back to an imaginary LoadableDetachableModel variant which would store a unique key, and load/store its object value from/to the PageParameters. I'd appreciate some advice: What would be the nicest way to get hold of the pageparameters in the current request from a model, and to set one in the next response? Or Is there some better way to achieve bookmarkable (partial) form state?

ListMultipleChoice to take choices model from parent
Hi there, We sometimes need a component for editing sets of arbitrary strings. We currently use a ListMultipleChoice component, whose choices model contains the actual set, and selected elements can be deleted with a button. Is there a simple way to instruct ListMultipleChoice to use the model looked up from its parents CompoundPropertyModel by its wicket:id as its "choices" model instead of its "selected elements" model? I can do new PropertyModel(parentModel,"myWicketId"), but its clumsy and more static. Or is there some other component we should be using to make a "free-text palette" set editor? (regular palette does not work, as we must have a text entry field for adding new elements, there is no finite universal set to chose from.) Thank you in advance for any ideas!

Re: How to set wicket's locale?
I'm planing to have a little celebration in our office when our webapp is officially released to customers.

How hard can it be to order pizza online in any language, I thought.

Thanks for the support and ideas.
But for the record:
Overriding getLocale() would surely work, but sounds like even worse
of a hack than setLocale(_), and when I set the locale in the
ISessionFactory it gets reset by the locale in the request just like
when I set it in the session constructor. (which is to be expected,
really.)
Here's my current plan to manage the locale (and to display the logged
in user while I'm at it), please tell me what's wrong with it, I get
an exception about the model being a null object:
public class DetachableSessionModel extends LoadableDetachableModel {
@Override
protected Object load() {
return Session.get();
}
}
public class LocalePanel extends MCCNPanel {
public LocalePanel(String id) {
super(id);
Form form = new Form("form");
add(form);
form.setModel(new DetachableSessionModel());
List locales = new Vector();
locales.add(new Locale("hu"));
locales.add(new Locale("sr"));
locales.add(CentrexSession.get().getLocale());
form.add(new DropDownChoice("locale", locales, new
ChoiceRenderer("language", "language") ));
form.add(new Button("submit"));
}
}
When I submit:

I saved this message from a few weeks ago, and I finally got around to localize my application. I use wicket 1.2 for now. I extended the wicket.WebSession class, and set the locale in its constructor, just to see if it works. It does not: the request overrides my setting, so I get my pages in the language I configured the browser to prefer. I do not want this, think internet cafes or locked down corporate machines. I can't override setLocale/1 to disable this feature, because it is declared final in wicket.Session. So what is the wicket way to make my application ignore the locale in the request?

We've been using wicket for a couple of months now, our first application is about to be deployed, so I looked back at the templates and started wondering how much this separation of concerns applies to us. We have a base page with some panels supplied by subclasses, then those panels are made up of subpanels, fragments, datatables, all with their respective HTML templates. We have a wrapper panel for each form input component to add a label and a nicer read-only view. All this even before we introduced a navigation border! We did start from a single HTML page from a designer, and all we had to do was slice that up, so there is some truth to the separation of concerns, but it is was a one-way road, there's no way the designer will understand all these HTML sniplets: We can only ask him to beautify a full, rendered page, and slice that up again to update the small template files. I'm not complaining or anything, haven't used any other web framework, and still can't see any I'd switch to, (well, theoretically, if designers could do OpenLaszlo all by themselves and we only had to supply the business logic via a web service...) just wanted to share my thoughts on the separation of concerns slogan.

We use RadioGroup for something similar and it works fine.
The form has a CompoundPropertyModel with attributes including
"radioGroup", "panel0", "panel1", which the subcomponents can find
even when they are nested into each other.
Here's a simplified example:
form constructor:
RadioGroup radioGroup = new RadioGroup("radioGroup");
Panel panel0 = new Panel("panel0");
Radio choice0 = new Radio("0", new Model(new
Integer(0)));
radioGroup.add(panel0);
radioGroup.add(choice0);
Panel panel1 = new Panel("panel1");
Radio choice1 = new Radio("1", new Model(new
Integer(1)));
radioGroup.add(panel1);
radioGroup.add(choice1);

WicketTester vs Component.error()
Hi, I'm using wicket 1.2, and use the WicketTester startPage(...) method in a unit test. (In fact there's nothing else in it, I just want to test if the markup matches the component hierarchy.) Problem is, a component on the page uses its error(...) method to display its dissatisfaction with the mock data in a feedbackpanel, which is perfectly normal operation. But that causes an exception: java.lang.IllegalStateException: No Page found for component [MarkupContainer [Component id = signInForm, page = , path = signInForm.LoginPanel$SignInForm]] Is this expected? Did I do something wrong? Any advice is appreciated. Upgrading to wicket 1.3 is planned, but I'd rather have tests even before that. Thank you for your attention and the great framework!

No, I think it's a quick hack to get it working in the component->model direction :-) I think the design of DropDownChoice implies you use a list of the same class for choices as the actual model. Then you use a ChoiceRenderer to pretty print them on the user-visible choice list. But I could be wrong because I don't remember seeing this in any documentation or tutorial :-) Or is there a way to express "this" in the property expression language? "." maybe? Because the rating string in your model object is the choice id itself. Gabor - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Fwd: [Wicket-user] editable form
Hi,
Sorry if duplicated:

I think what happens here is form.setCategory(ratingList.get(chosenOne)).
That's why you see generic toString output as the assigned value.
As a simple hack, you could override the toString() method of the rating class.
For a semi-decent solution, override the convertValue method of DropDownChoice.
I think what you really need is to add a Converter to ratingChoice.
(but IConverter does not extend IBehavior, so I don't know how to do
that properly)
I also don't know how these conversion tricks will work in the reverse
direction, when displaying the rating already in the model.
And in an unrelated note, you could call this component "category"
instead of "rating", and give a CompoundProertyModel to the form.
Saves a lot of typing in the long run,
