Re: Scala DSL for Wicket
Just wanted to share my experience playing a little more with Scala and
Wicket A few minutes ago I got this excelent code:
I know it is too simple, and it can be accomplished as well in Java with
static imports. But still, for my project it's being great (and cool) to do
such things.
object btnEditar extends Button(btnEditar) {
override def onSubmit() = {
-/* show fields */
-camposForm.setVisibilityAllowed(true)
-btnSalvar.setVisibilityAllowed(true)
-cancelar.setVisibilityAllowed(true)
-
-/* hide them */
-camposTela.setVisibilityAllowed(false)
-btnEditar.setVisibilityAllowed(false)
+show(camposForm, btnSalvar, cancelar)
+hide(camposTela, btnEditar)
}
}
add(btnEditar)
Methods show/hide are imported as import code.DSLWicket._

Thanks Martin,
There was only a small little problem in your code. The correct syntax is:
def label[T](id: String, model: IModel[T] = null): Label = { val label
= new Label(id, model); add(label); label }
The suggestions were updated on Gist.

Idea for simplification: use named parameters.
For example
def label[T](id: String, model: IModel[T]): Label = { val label = new
Label(id, model); add(label); label }
would become
def label[T](id: String, model = _ : IModel[T]): Label = { val label =
new Label(id, model); add(label); label }
this way you'll have just one declaration of label function which will
handle the current three
additionally you may add a pimp:
implicit def ser2model[S : Serializable](ser: S): IModel[S] =
Model.of(ser)
now even when you pass String as second param to label() it will be
converted to IModel

they should.

The method onSubmit() of button is void, as well onClick(), so there's

Problem while decouple page flow by using SpringBean
Hi,
i would like to decouple the page dependencies. My page flow is
implemented by using bookmarkable page links.
As we all know they take a page class as parameter. This couples both pages.
So i thought it's a good idea to give the page class a name in my Spring
application context and reference it in
the caller page.
public StartPage extends WebPage {
@SpringBean(name=nextPageClass)
private Class? extends Page _nextPageClass;
public StartPage() {
add(new BookmarkablePageLink(toNextPage, _nextPageClass);
}
}
My application context defines:
bean id=nextPageClass class=java.lang.Class factory-method=forName
constructor-arg value=my.NextPage/
/bean
But it's not working while java.lang.Class is final. I get
Caused by: java.lang.IllegalArgumentException: Cannot subclass final
class class java.lang.Class

Re: Problem while decouple page flow by using SpringBean
Found a solution, but would be great if i could get some tips about the
consequences.
I was wrapping the beans in proxies by setting the flag in
SpringComponentInjector to true.
Now it's set to false and it's working. But i'm a bit in doubt that i
opened pandoras box
with this.
It was
addComponentInstantiationListener(new SpringComponentInjector(this,

and is now
addComponentInstantiationListener(new SpringComponentInjector(this,

Re: Problem while decouple page flow by using SpringBean
It is quite easy to extend SpringComponentInjector so that it will
look for another annotation, e.g. @SpringBean2 which wont be proxy-ed.
Yet another one is to create a ticket to add an additional attribute
to original @SpringBean (proxy = false).

Or, put another way, maybe the question would be what I wished I knew when I started Wicket - what tripped you up or what made you kick yourself later? Not ten things, but a few anyway. This is what I really try to get across in training classes: - Understand how models work, that they are a shared reference to a domain object, and they connect your components. If you find yourself shoveling data around manually, have a second, third and fourth look at it, you're probably doing it wrong. - Detach your models. There's a simple rule: Any model that you instantiate or that you get passed in from elsewhere you need to either - detach yourself - or pass it to another component, thus delegating the responsibility for detaching it. Detach it or pass it on. - Try to use as few instance variables in your components as possible. Use instance variables only for handling state completely internal to your component. Use models for everything else - that is, everything that might be visible from outside your component. Internal state is stuff that never leaves your component, neither to whomever called you, nor to anything you call. The latter includes components that you aggregate in your panel. This rule greatly simplifies refactoring later on. - Did I mention that models are important? :-) Carl-Eric www.wicketbuch.de - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Ten things every Wicket programmer must know?
In my humble opinion: The most important thing that you should know are models en how powerfull they can be used. Models can be quite confusing, especially to programmers who've just started using Wicket. I remember how I struggled with the concept, when I started to use Wicket. How and when to detach them, how to use them when using an ORM-framework, etc. Ted 2011/7/28 Carl-Eric Menzel cmen...@wicketbuch.de On Thu, 28 Jul 2011 11:10:30 +0300 Martin Makundi martin.maku...@koodaripalvelut.com wrote: * compressing code by use of ids matching property names combined with CompoundPropertyModel and/or PropertyListView Oh.. that will lead to fragility.

Re: RFC: Ten things every Wicket programmer must know?
From my experience, stuff where I screwed up or wasted time: 1. Wicket is a UI framework, delegate as much as possible to your own neutral code base service and components. Data Models etc. Both Server and Client Side. Client Side:: Don't wrestle with Grids etc in Wicket; if you can get away with a cheap JavaScript/DHTML implementation instead. 2. Wicket Data Models should ideally wrap you native business objects. Wicket wotks over the native business objects; your business objects POJOs are not designed for wicket. 3. Use Detachable models effectively. (Am still learning the meaning of *effectively*). Example: Everyone talks about using it, but it depends on the underlying business objects in use. If they are poorly designed and load in an in-effiient manner, then load() will mess with re-loading stuff each time. 4. Do not try to instantiate Wicket Components via Spring. there is no sane reason to do this; this was an area of special interest and very tempting. One can rely on Spring for native objects and develop better mechanisms for Components to instantiate over the Spring defined layer. 5. @SpringBean is bloody useful 6. Learn to hack Mount Paths. The default Markup Page classpath relating to the component is Web non-intuitive. Its great if you can live with the default setup but learn to mess around with mounting. 7. Learn to the differences between Markup Inheritance, Use of Panels and Include when it comes to designing reusable templates and reducing boilerplate markup code. 8. Mess around with Fragments; they are useful. Like Anonamous classes ; but just in the markup world. 9. Learn atleast one other Web Framework like Struts, appreciate the beauty of Wicket. 10. Learn to respect velocity templates and the co-existence of Wicket with Velocity.

Re: Problem while decouple page flow by using SpringBean
Thanks Martin for the work-around.

i would like to decouple the page dependencies. My page flow is
implemented by using bookmarkable page links.
As we all know they take a page class as parameter. This couples both

So i thought it's a good idea to give the page class a name in my
Spring application context and reference it in
the caller page.
public StartPage extends WebPage {
@SpringBean(name=nextPageClass)
private Class? extends Page _nextPageClass;
public StartPage() {
add(new BookmarkablePageLink(toNextPage, _nextPageClass);

My application context defines:

A safer way to build PropertyModels, version 1.2
https://github.com/duesenklipper/wicket-safemodel As I wrote earlier on this list, SafeModel lets you turn the fragile strings of this: IModelString childNameModel = new PropertyModelString( myBean, child.name); ...into this, gaining refactor-safety: IModelString childNameModel = model(from(myBean).getChild().getName()); I have just built SafeModel version 1.2, with the following improvements: - fixed an oversight in the initial version: You can now use a model as your root object for the from() method. - Based on an idea from Matt Brictson, you can now quickly build LoadableDetachableModels using fromService instead of from: IModelUser userModel = model(fromService(userEJB.loadUser(42))); This is experimental. fromService may be refactored later to end up in a different class (but that would at worst force you to change imports, so no big deal really).

Re: RFC: Ten things every Wicket programmer must know?
Hi Jeremy, I think the most important things a wicket programmer should know relate to building their own set of resuable components.Here are my top ten on that theme: 1. Build a reusable set of components tailored for your business domain. 2. Solve a few problems then push up the common functionality into an AbstractBaseComponent class where the other uses are subclasses. 3. Or externalize the component setup choices through an interface and keep the class non-abstract. Then the callers setup an implementation of the interface for each case. The interface would control things like show/hide on no results or enable/disable certain fields, basically any choice that is useful to externalize. 4. Understand how extending FormComponentPanelBusinessObject can hide complexity and provide improved form validation options. e.g. We have a query application and the form builds the Task to be executed. We have a filter that contains ListVariableFilterfilters and each Variable Fitler is itself a ListStringoptionsList. Creating a custom Form component at each layer we can be assured that the complicated elements at each level have been validated properly before the task is submitted. Since the top level submit need only deal with the objects being assembled into the task, their internals are assured to be valid. 5. convertInput needs to setConvertedInput(new BusinessObject()) and this is what the validators run against. Only when they pass does the modelObject = convertedInput. 6. Build separate class files for custom Models and Columns (no dynamic inner classes) since any IDE can easily handle the separation and because having them separate enables more reuse. 7. Know how repeaters like ListView and DataTable work and internalize them within your own panels to hide their complexity from the callers of your panel. 8. Know how to emit javascript to the browser both as one off and in terms of a custom DOM object for your application. Especially important is how to write this javascript so that it will scale. i.e. the panel can be used more than once per page. 9. Understand wicket serialization, typically with the experience of having your spring container with some big data store write out to disk on each page change. A versioned page with ajax and this case is the most fun. And how @SpringBean creates serializable proxies that prevent this. But also how getting an inner object from the @SpringBean proxy will leave you open to the same cascading serialization issue. 10. Understand how to layer models to traverse the BusinessObject graph to access certain fields. Don't use PropertyModels in production instead layer models to access the fields of interest. e.g. new BusinessAccountModel (IModelBusinessAccountbackingModel, Type.ACCT_NUMBER) to create the get/set pair for the account number from the backing model. I can image the backing model being a LoadableDetachableModelBusinessAccount() that loads the account data from the database.

resource file handle issues on windows?
Greetings, We are in the process of migrating our project to 1.5 and have discovered an issue with editing CSS and JS files with the app serve running. We're curious if there is anyone else experiencing similar issues. We are working on Win7 with eclipse running Jboss 5 locally with wicket 1.5. The issue is that when the server is running and editing a JS or CSS file that is referenced via the renderHead method saved changes are not copied by eclipse to the output directory. It logs a warning to the console WARN [UrlResourceStream] getLastModified for file:/C:/path to project/path to component or panel.html/ It does so for every panel or component html file that was present on the page that was open in the browser where you were editing the CSS or JS on the page. It appears that there are still file handles open by wicket or jboss when that happens. Eclipse is not able to build the project after this because if can't delete the jar file that the opened files are in so it takes a project clean and server restart to get things going again. Has anyone else who is developing on windows seen similar issues with editing CSS or JS with the app server running or any other ideas as to what might be the cause? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/resource-file-handle-issues-on-windows-tp3701938p3701938.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: What does this syntax say?
This syntax is for use when you need a generic placeholder. In this case, it means that W is determined by the call site: IModelBusinessObject model = OtherModel.wrapOnInheritance( Component ); The above means that W is checked to be BusinessObject for all occurrences of W. A better to understand example is to have a look at java.util.Collections, eg: addAll http://download.oracle.com/javase/6/docs/api/java/util/Collections.html#addAll%28java.util.Collection,%20T...%29 It's signature is: static T boolean addAll( Collection? super T c, T... elements); Which means: you can only add elements of the generic type constraining the collection (e.g. only add String elements to a CollectionString).

Generic types are lost by the time the method is executed, so there's really nothing the method implementation could check. Another fun example is org.apache.wicket.model.Model#of(). The general subject is called type erasure, and is one of the more confusing aspects of Java generics.

getInput and getDefaultModelObject and validation
If I am using some form validator, I notice that getDefaultModelObject
does not have the value from the getInput. I am assume this
intentional. Is there a way to force wicket to update the modelObject?
How and when does the modelobject get updated.
myForm.add(new AbstractFormValidator() {
public void validate() {
String val = component.getInput(); --- has the correct value
from the request
String val2 = component.getModelObject(); does not have
value.
}
});
...
In the case above, I could use the proper ajaxbehavior (like onBlur on a
textfield) and the modelObject gets updated.
But if I weren't using ajax, is there a way to force wicket to update

Right but Model.of accepts an instance of the generic type so it's not lost and is available at runtime. static ModelT of(T instance) vs. public W IWrapModelW wrapOnInheritance(Component component) On Thu, Jul 28, 2011 at 6:33 PM, Dan Retzlaff dretzl...@gmail.com wrote: Generic types are lost by the time the method is executed, so there's really nothing the method implementation could check.

Ajax broken in IE 8
Wicket 1.4.9's Ajax doesn't work in Internet Explorer; in particular, AjaxFallbackButtons fall back to non-Ajax POSTs, and the Wicket Debug window is never seen. In 1.4.17, Ajax is still broken, but the fallback never happens, because Ajax sort-of works: the the Wicket Debug window doe show up, and when the AjaxFallbackButton is clicked, a attempt is made to to XMLHTTP, but fails with Automation server can't create object. This looks like the same bug as reported in https://issues.apache.org/jira/browse/WICKET-3887 and https://issues.apache.org/jira/browse/WICKET-1432. It's apparently fixed in 1.5, but while bug 3887 is claimed to be fixed in 1.4.18, the latest snapshot exhibits the same behavior as 1.4.17. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: What does this syntax say?
I actually meant the no-argument version of of(). Since this is getting off-topic, I suggest you search around under java type erasure. There are people far more expert than I to describe what's going on. :) On Thu, Jul 28, 2011 at 9:26 PM, Ben Tilford b...@tilford.info wrote: Right but Model.of accepts an instance of the generic type so it's not lost and is available at runtime. static ModelT of(T instance) vs. public W IWrapModelW wrapOnInheritance(Component component) On Thu, Jul 28, 2011 at 6:33 PM, Dan Retzlaff dretzl...@gmail.com wrote: Generic types are lost by the time the method is executed, so there's really nothing the method implementation could check.
