WicketFilter 1.5
Hi, WicketFilter with 1.5 doesn't seem to use/support 'getRelativePath' any more. I used to override this to apply Locale selection and stripping this information off: /de/myRelativeWicketPath - /myRelativeWicketPath + Session Locale 'de' Where can I hook that now?

Re: Scala, dependency injection and wicket
Hi Haim,
Yes, I remember seeing that. How would you add it to wicket? by adding
ServiceInjector trait to the Application class or using the wicket-guice way
(addComponentInstantiationListener(new GuiceComponentInjector(this));)?
the Injector is just a trait, so anywhere it's needed, I just add it to the
corresponding class - whether it's a Wicket component or not doesn't matter. So
you have
class MyWebPage extends WebPage with Injector {
@Inject val domainRepo: DomainRepo = domainRepo
}
class DomainRepo extends Repo with Injector {
@Inject val customerRepo: CustomerRep = customerRepo
}
This is a general approach, so no need to add a intantiation listener.
One more question though, In the example you're only using constructor
injection. Any reason not to use field injection?
Actually, I use field injection most of the time, see above.
Best regards, --- Jan.

Re: server push
Hi Jahid, We need server push for one of our web application. Is there something that you can suggest? The requirement is, it should work on any server (Tomcat, jetty, jboss,). is there any wicket component that does this? as far as I know there isn't any standard yet which works on any servlet container. This is on the roadmap for the servlet api 3.0. Tomcat has a different API than Jetty than resin. I'm going for pull ATM, which works fine for my purposes. But your mileage may vary.

Re: Wicket-Scala extensions
Hi Antony,
great to see Scala and Wicket getting more popular. :-)
I've been using them together quite a while now and am convinced that there are
lots of benefits in it!
I created a dynamic component (like wicket:component which isn't officially
supported) which also works with Ajax. There's also a 'VarModel' which is
similar to your Fodel. You'll find the sources here:
http://www.footprint.de/fcc/2008/11/some-wicket-scala/
I also use Scala's mixin capabilities to abstract layout information out of the
pages/components. E.g. to define cell styles of datatable columns or to format
cell output, I have something like:
trait Centered[T] extends IStyledColumn[T] {
abstract override def getCssClass: String = {
val style = super.getCssClass
if( style==null ) columnCentered
else style + + columnCentered
}
}
trait DateFormat[T] extends PropertyColumn[T] {
override protected def createLabelModel( embeddedModel: IModel[T] ):
IModel[_] = {
val m = super.createLabelModel( embeddedModel )
m.getObject match {
case dt: DateTime = VarModel( dt.toString( dateFormatter.withLocale(
getLocale ) ) )
case _ = m
}
}
}
To create/apply a cell to use this style I just have to apply this trait:
val col1 = new PropertyColumn[M]( new Model( Date ), COL_DATE, reg_date )
with Centered[M] with DateFormat[M]
Scala's just great to abstract more between logic and layout.

Re: shorter input names
Hi Ian, Thanks for that. For your solution to work it looks like wicket would need to only call getInputName at most once for each input (since subsequent calls would return different names). Is that how it works? no, within the trait I override the 'def getInputName' from Wicket with a 'val getInputName' - i.e. even when Wicket is calling it more than once it is still only evaluated once. That's another nice thing Scala provides... :-) Best regards, --- Jan. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: shorter input names
Hi Ian,
Is there a way to get wicket to generate shorter name attributes for
input elements? I have a largish form and most of the data being sent
to the server is the names of the input elements.
it is by overriding the method 'getInputName' on every FormComponent and
returning a stable identifier over requests - though this is pretty horrible
task to do.
If you're using Scala instead of Java things are getting better, though. I
defined the following trait (aka implemented interface):
---
object FormInputNameId {
private var currId = 0
private def getName = {
if( currId==Integer.MAX_VALUE-1 ) currId=1 else currId = currId + 1
fid: + currId
}
}
trait FormInputNameId[T] extends FormComponent[T] {
override val getInputName: String = FormInputNameId.getName
}
---
This trait can be attached to any FormComponent with just something like
val newFormComponent = new TextField( id ) with FormInputNameId
The Scala compiler does the rest for you (one of my favorite features of Scala
to have real reusable code!).

Re: How To Download Excel File?
Hi,
I could be wrong - but maybe the question is about how best to structure
this in Wicket ..
it's just that easy (this is Scala, not Java):
add( new Link( ImageLink.ID_LINK ) {
def onClick = {
val resourceStream = new ByteArrayResourceStream(
xlsExporter.createExcel, application/vnd.ms-excel );
getRequestCycle.setRequestTarget( new ResourceStreamRequestTarget(
resourceStream ) {
override def getFileName = export.xls
} )
}
})
ByteArrayResourceStream is a simple implementation of IResourceStream. Creating
the Excel bytearray is another issue (I suggest using Apache POI).

Re: Making wicket work with Dynamically created html
Hi Vasya, The velocity template is pretty good at displaying the html elements dynamically, but im not finding an easy way to bind the data back... I'm not really sure what you're trying to accomplish. You can't use the velocity to create wicket-components on the fly and have them bound to a form, that'll not work. If you want to create some dynamic form you should use repeaters and build them up using them - and bind the formcomponents directly to the model (maybe you need to write some specialized model yourself). I did something like that with XML specifying the form and having a ElementModel binding the form elements to JDOM nodes.

Re: handling not mounted URLs
Hi Jeremy,
Can you mount another filter that, if Wicket does not respond, instead
responds with either a valid page or a redirect back to a valid Wicket page?
no, that's no option. I got the ErrorPage-Version working in the way that I
manually set the status code with
val uri = req.getAttribute( javax.servlet.error.request_uri
).asInstanceOf[String]
if( uri!=null ) {
val res = getResponse.asInstanceOf[WebResponse].getHttpServletResponse
res.setStatus( 200 )

That way you get a 200 on the client.

Re: Things I miss in Wicket
Hi Tobias, I don't agree on a couple of points you made on Wicket. Wicket is providing the GUI and you have to make sure your gluing to the backend is as transparent as it can be. So, if you have your interfaces untouched, you wont need to touch the Java code again for your 3-5 years. Also, wicket allows easy separation of your markup from your Java code, making redesign not that a big task as you suggest (given that the hierarchies need to be kept). But, I think a web /application/ is meant to evolve and not left untouched for years. Another thing about Wicket: It's all about reusability. If you design components, you can jar them up and just drop them into another project. That's one thing most frameworks don't allow. If you want to sell a product and don't want the customer to know Java: get your resources from a database and integrate some kind of templating. It just works with Wicket as well. I think I write my web applications at least as fast as you do with PHP. I have my established Wicket base and just put together the components I need: drop in authentication, localize things, complex wizards... I doubt you'll be that error-free in writing such code with PHP than you'd do with Wicket as a base. I never needed to debug much with Wicket at all. Most PHP I've seen mixes business logic and user interface so badly that - when you need to enhance things - you're really in trouble.

TextFilteredPropertyColumn[T] and getFilterModel
Hi,
I'm trying to work out how to handle TextFilteredPropertyColumn with wicket 1.4.
I'm trying to do the following:
tf = new TextFilteredPropertyColumnM( new Model( Name ), COL_NAME, name ){
protected IModelString getFilterModel( FilterForm form ) {
return new PropertyModelString(
getDataProvider.getFilterState.getFilterMap( FilterMaps.LIKE ), getSortProperty
)
}
}
COL_NAME (= sort property) / Filter value are organized in a simple
HashMapString,String.
This worked fine with Wicket 1.3.x - Wicket 1.4 insists that getFilterModel
returns an IModelM - which is obscure, since the filter doesn't have to match
the Model of the Column.
Am I missing something?

Re: Migration to 1.4 - generic headache
Hi Igor, yes it sucks. i agree. personally i prefer code written against wicket 1.3. even in 1.3 i hardly had to cast anything and even with those casts i do not remember getting any class cast exceptions. hehe - just as I was saying months ago. *g* anyways, we will see how it goes. until 1.4 i think the generics will stay the way they are unless we hear a ton of users complaining.

Re: Migration to 1.4 - generic headache
Hi Igor, you are against generics completely. but they are going to happen. the way they are now is not perfect, in 1.5 we will try to move them to a better place, but like it or not they are here to stay. huh - hell, no, I'm not against generics at all. Where do you get that from? I'm against generics on Components which are not FormComponents (or ListViews)! I'm using Wicket together with Scala and other than with Java, I can't just drop the generics attributes (and live with the warnings). And the Void is really a hell of a generic... Generics on Models are what is needed and if your vision to decouple models from the component and use introspection/reflection to support them comes true I'd be quite happy (and could use Scala's mixin-feature to have my model functionality on the components).

Re: wicket-ioc/cglib constructor injection
Hi Igor, add a package private default constructor to your class. default constructor wont work in this case. these are all well known limitations of proxying classes, you should try to make sure your injected dependencies are interfaces or you something like salve so no proxies are needed. Defining an interface for the class results in wicket-ioc not injecting the original class/constructor at all. So there's a flaw with this approach.

Hi, Google Analytics? I have my problems with this, actually. There are privacy-policy-issues with Google Analytics, especially in germany.

Google and other companies are started to be questioned about this service and how they comply to German laws on this matter ([1], [2]) - and I for one find the questions valid.

Re: users, please give us your opinion: what is your take on generics with Wicket
Hi Gabor, I was thinking about using the existing wicket 1.4 API from scala, if that's any more comfortable. I tried to migrate a bigger project from 1.3 to 1.4 api - and it isn't really more comfortable. It's easier to do one or two casts than trying to conform the generics Component structure. Especially since there are cases with 1.4 generics (like StringResourceModel) which sometimes aren't recognized as IModelString (which of course is more a Scala than a Wicket problem)...

Re: users, please give us your opinion: what is your take on generics with Wicket
Hi, I'm not sure I like where this discussion is going. I don't see anyone having any particular objections against current state. @matej_k: ugh - you should count again... if I counted right, most of the responses yet prefer 'Component' /not/ being touched by generics. +1, I agree. I think this discussion might be counter-productive if folks who aren't using the generified versions are voting. @jwcarman: There is an issue with generics on components which is leading into a big mess - and as far as I can see, many objections are especially on that topic! It might not be Wicket's fault, though, it might be a language problem (i.e. Java's to blame). But IMHO putting generics on Component is a bad design, since it per se touches all of Wicket's Components without urgent need. Boilerplate over and over. If I look at my components and libraries (and yes, i have tried out 1.4!) - I have at most 30% of my components containing a Model!

The main point is (repeatedly) ignored by the people who are 'pro' generics: Why do you have to put generics on Components, when need is only in a fraction of cases? Discussing the possibility of Void is somewhat an obscure workaround. It's just boilerplate in more than 70% (of my cases), and this boilerplate gets repeated over and over again with each assignment.

Hi Sebastiaan, I *really* would like to see a clarification of this statement. In Wicket the component and model are very tightly coupled. that's part of the problem, agreed. What is a *good design* alternative, where only IModel is generified? getModelObject() returns Object? getModel returns IModel?? IMHO the practical solution would be to leave generics from components and have getModelObject return Object, yes.

hi sebastiaan, You could use Java's covariant return types to override getModel() to return a specific type. Which would mean that you would need to subclass to simulate generics (with a new subclass for each type). not really, you can do generify your components from a certain level and wouldn't have to subclass for each type. that way you could require formcomponents to have generics on them, without the whole component tree generified. but i guess this would also lead to many questions why this and not that... i'd prefer living with have to cast when it comes to getModel/getModelObject... regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: (Class? extends Page?) casting troubles
Hi Johan,
I thing that the example below is exactly the thing that generics are pretty
good:
populateItem(ListItemPerson item) {
add(new LinkPerson(edit, item.getModel()) {
public void onClick() {
setResponsePage(new EditPage(getModelObject()));
}
});
(and EditPage is by itself already generified to Person)
well, just that the LinkPerson is IMHO redundant and unnecessary(just dropped
a note to Martijn, but since you brought that up...)
populateItem(final ListItemPerson item) {
item.add(new Link(edit) {
public void onClick() {
setResponsePage(new EditPage(item.getModelObject()));
}
});
So, it might have sense with ListItem, but not necissarily with Link...

Re: (Class? extends Page?) casting troubles
Hi Johan,
But i really dont think that Person in link is redundant why is it?
the point was, that in this case Link simply doesn't need to have given a model
at all, since you can access the surrounding final vars (you can access the item
in onClick):
populateItem(final ListItemPerson item) {
item.add(new Link(edit) {
public void onClick() {
setResponsePage(new EditPage(item.getModelObject()));
}
});
What else could you do/access in Link what is not possible with this approach?

Hi, IModel getModel() Object getModelObject() I can live with having these methods not being generified. for my own cases, generics have been also been more pain- than helpful with Wicket. I don't see any _real_ advantage in having all components needing a type just for the sake of typing IModel. Isn't there an alternative approach? I'd suggest moving to scala - but that's no real option I suppose... ;-) Else one could just externalize the Model handling out of Component into a Trait which could be generified. For Java actually I have no idea how that could be accomplished for Wicket... Best regards, --- Jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Scheduler in wicket
hi, I am planning to use quartz, but before starting to integrate it in my wicket's app i would like to know if anybody have used it or another scheduler with wicket. quartz is a good choice - it just works (tm). best regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why Localizer Retained so many heapsize?
hi johan, I will also open up Localizer api a bit more so that you can override the cache that is used: please make sure, that you also remove the direct access on the cache to check if it contains a certain key: // Value not found are cached as well (value = null) if ((cacheKey != null) cache.containsKey(cacheKey)) Best regards, --- Jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why Localizer Retained so many heapsize?
hi johan, why? we just have a protected factory method now for a cache implementation that must be a map. if you open up the api to change the implementation of the cache - there are other implementations than map... why limit it to map? (actually, I don't really understand the cache.containsKey(cacheKey) at all since it could just be checked for null when getting the value)... best regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why Localizer Retained so many heapsize?
hi johan, we just have a protected factory method now for a cache implementation that must be a map. another point to that: why not expecting a general cache implementation as you do with MarkupCache.ICache ? best regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
